So I have an application with a dashboard and a main page that has a header. Both of them have a react-bootstrap-typeahead input to perform the same action - a search to open something on a map.
What I would like to achieve is:
when the user search something on the dashboard, the main page opens with the search result and on the header, the search input there shows what was searched on the other component.
on the other hand, when the user search something on the search input on the main page header, and then goes back to the dashboard, the dashboard search input should be prefilled with the value previously searched on the main page.
What I have tried so far:
So when the user picks a search item result, that string is saved on the application state using redux. I also clear it manually when the user clicks on the clear search button. The RBT component is defined to use this variable, as in:
<AsyncTypeahead defaultInputValue={props.currentSearchValue} ... />
This seams to work on the first time, i.e. when the user has not interacted with the other input yet. For example, with the application on a fresh state (just loaded) if on the dashboard I pick a search item, when going to the main page because that search input has not been touched yet. Then, when I pick a search item on the main page and go back to the dashboard, I wouldn't see it because setting defaultInputValue is not enough, as that input is not in its default state anymore.
Any tips? I have been running in circles so far. Tried the key/setKey workaround as described in another answer, but that wasn't enough to cover the case described on the previous paragraph. I also tried comparing the input value to the recorded value, but naturally when starting to typing with the input field the values would be different and therefore I cannot trigger a component reload based on that.
Thanks in advance.
Unless I'm missing something about your use case, the selected prop should do what you need. You can save the selected item(s) in your redux store and populate the typeahead with the value on the given page.
// Get the initial value from the store. This should be an array.
const typeaheadSelections = useSelector(...);
<Typeahead
...
onChange={(selected) => {
// Update the value in the store when the selection changes.
dispatch({
type: 'set-typeahead',
value: selected,
});
}}
selected={typeaheadSelections}
/>

I'm trying to make a form-fillable pdf where List Boxes will affect other parts of the sheet.
I have several Hidden Paragraphs in my document (hiding graphics, etc), and a List Box. I'd like to use the List Box choice as the Condition to dynamically hide and unhide the various Hidden Paragraphs.
Example: The user selects clicks on the List Box, and Cat, Dog, and Bird are listed. If the user selects "Dog" from the list, the paragraph with text and pictures of dogs is no longer hidden.
I get that I have to do Hide Paragraph if [List Box choice] != "Dog" as my Condition, I just can't figure out where to get the List Box choice. Feels like I hit a wall in searching for an answer or guide because I'm missing specific terminology (field? formula?).
I am actually trying to do the same thing, and I'm getting very frustrated by it. I developed a case management database for my law office (actually, it pretty much manages almost every aspect of the office at this point), but because we handle all kinds of different cases (criminal defense, civil litigation, probate, etc.) the information we need to track often varies. For instance, on criminal cases, we need to keep track of the sentencing guidelines scoring, the current offer from the prosecutor, prior convictions, and so on. For family law cases, we need to keep track of things like assets, parenting time schedules, etc. Putting all of these variable on one page at the same time gets very cumbersome very quickly, so I'm trying to set the form up so that when you select a case a "criminal defense", it shows the "Criminal Defense" portion of the page, and hides the "Family Law", "Civil Litigation", "Probate", and other portions.
The only way I could come up to do it was the create a variable (in this case, I called it "CaseType") and set the paragraphs to hide or be visible depending on what the variable is set to. This works great, except (a) it's awkward making users select the type of case it is for database purposes, and then making them select the type of case details to display in the form; and (more importantly) (b) the user has to type the required value of the variable into the dialog directly, which is a pain. I would much rather be able to have the type of sections that are displayed determined by the value of the case type in the database, or at the very list have the panels displayed in a dropdown list.
I came up with an idea to record a macro that would run when you pushed buttons--for example, press the "Criminal Case Panel" button and a script would run that selected the variable via double-click, entered the correct value in the dialog box, and then applied the new variable, but it seems that Writer will not let you record macros that change values in dialog boxes.
There is so much untapped potential in this aspect of the software; if the user variables could be set by forms--or if the "hidden" flags could be triggered to be hidden by the values of database variables--it would open up so many possibilities. Makes me wish I had the coding skills to work on this part of the software.
According to https://help.libreoffice.org/7.0/en-US/text/swriter/01/04090200.html, you can set up a database for Writer conditions. It looks like this would work with LibreOffice Base, where forms with list boxes can be created.
However, if you are trying to use values from a list box in a standalone Writer template or other document, then looking at that link, it does not seem possible. Writer conditions are restricted to document metadata, not the contents of the document.
One solution is to write a macro that pops up a dialog with a list box, and then when the dialog is closed, modify the Writer document based on the selected values. LibreOffice has a dialog development front end to help you set this up, and then you would need to write code to execute the dialog and do the changes. See https://www.pitonyak.org/oo.php for help writing the necessary code.
I'm trying to implement a live search combo. It suppose to work like this:
When I enter a character into the combo field I read the current value and send it as a parameter to the store's url. In the backend the parameter is used to return any value from the database that contains it, so the store behind the combo gets filled only with those filtered values.
As I continue to enter characters into the combo, the parameter should be updated and sent again to the backend and so on, getting like this a smaller and smaller store.
I tryied to achieve this behaviour using the combo's event keypress, even keyup, but the problem is it's impossible for me to get access to the current value from the combo field.
For example, when I entered the "for" string into the combo, how can I obtain this value using the combo object? comboName.getValue() doesn't work, it returns nothing "".
I already saw the live combo example here: http://docs.sencha.com/extjs/4.2.2/#!/example/form/forum-search.html but doesnt help me at all.
So my big question is: how do i get the current value while still editing the combo's field?
Any help would be appreciated, thanks.
You should be able to use
comboName.getValue();
or
comboName.getRawValue();
Where comboName is your combo box. Are neither working- I note in your post you state getValues() which is an improper method. You may want to also check whether when you're referring to your combo box object, that the reference is actually correct. The first argument from the key events is actually the object itself, so you should be able to do, e.g.
listeners:{
keyup:function(comboBox){
var value = comboBox.getValue() || comboBox.getRawValue();
console.log(value);
}
}
Swapping you the value getting method as appropriate.
I found that the combo already has a quick search behaviour, I just have to set queryMode on 'remote' and some other small configurations. More details here:

In Drupal 7, is there a way to change the standard edit form for a content type based on a certain content?
For example:
I have a content type with a checkbox...once it it checked and the form is saved, I do not want this checkbox to be visible anymore...therefore based on the checkboxes value in the Database I want to hide form fields when showing the form.
I am building a small specific project site, where a company wants to add projects, and their customers are supposed to follow certain steps (upload some content, provide information etc.), and also should be able to check off certain requirements, and once these are checked off, they should not be visible/editable to them.
Also the displayed form fields should depend on an user's role, and then FURTHER be limited depending on the content's database entries.
Is there a module, which could achieve this behaviour? "rules" and "field/permissions" come close to what I need, but are not sufficient. Or did I just miss the option to change a form field's accessibility based on conditions?
What I need is some place to define a logic like "IF (VALUEOF(CHECKBOX_1) == TRUE) THEN DO_NOT_SHOW(CHECKBOX_1)"
hook_form_alter is the way to do this, as explained by Mihaela, but what options do you have inside that function?
If you want just to disable field (it will be visible, but user can't change it) you can do it like this:
$form['field_myfield']['#disabled'] = TRUE;
And if you want it to be hidden, but to keep value it has before editing the way to do that is:
$form['field_myfield']['#access'] = FALSE;
I.e. hiding it (somewhere I saw someone suggesting that):
hide($form['field_myfield']);
really hides the field, but after that, when form is saved this field has empty value, validation fails, etc, so that's not a good way to do this. Hiding makes sense only if you want to print separately that field later, at some other place.
function your_module_form_alter(&$form, &$form_state, $form_id){
switch($form_id) {
case 'nameOfTheNode_node_form':
//your code here. check the value from from_state.
break;
}
}
In this case, I use module Conditional Fields https://www.drupal.org/project/conditional_fields
For example: If my Dependees field has a value, Dependent field can be visible/invisible, enabled/disabled, required/optional, checked/unchecked
I have a window with a search form at the top and grid at the bottom.
User can enter values in the search form and click button - Get Records.
At the click of this button, I load the store of the grid by passing the values in form fields as parameters in following way:
store.load({
params:{
key1:Ext.getCmp('field1').getValue();
}
});
I tried giving parameters in the store proxy itself, but it unfortunately always takes up initial values (values when the form is rendered) and not the latest one entered by the users in the form fields. Following is the method I used for assigning values to params while creating the store:
extraParams:{
key1:Ext.getCmp('field1').getValue();
}
I wanted to seek guidance at two things:
a. While defining a store, can I ensure that store takes latest/current values from the form fields before querying server, so that I don't have to provide these values while calling load function?
This becomes more necessary as I have a paging toolbar at the bottom which carries a refresh button (along with next, last, previous, first icons for navigation).
Now, whenever user clicks at refresh (or any navigation icon), the store gets loaded without the query parameters.
Thus the second thing is:
b. If the answer of 'a' is that - Pass the latest values to parameters manually when calling load function - then how can I write the handler for 'refresh' button and navigation icons (that is, next, last, previous and first) in the paging toolbar, so that I can pass the latest form values to load function.
Thanks for any help in advance.
PS: I am using ExtJS 4.
yourStore.on('beforeload',function(store, operation,eOpts){
operation.params={
status:cmbStatus.getValue(),
value:txtBuscarPor.getValue(),
empresa:'saasd',
app:'dsads'
};
},this);
Related to your question (b) (and because you especially asked for this in the comments section):
I see only one standard way to hook into the PagingToolbar button handlers which is very limited.
Ext.toolbar.Paging fires a 'beforechange' event before it actually changes the current page. See API docs. A listener that returns false will stop the page change.
All other methods require extending Ext classes which wouldn't be a problem if the ComboBox would make it easier to use your own implementation of BoundList (which is the class that renders the dropdown) or pass through config parameters to BoundList resp. the paging toolbar.
I tried to bring this lack of flexibility up on the Ext message board once but was pretty much ignored.
A possible solution for this is to use 'beforeload' event of the store and provide the list of parameters in it. This way, whenever the store is loaded, then its beforeload event is fired and the values picked up are always the latest. Hope this helps someone looking for something similar.
OK, let's start with the Html.Textbox. It is supposed to contain text read from a file. The file read is based on what the user picks from a dropdown list.
The first time it is fine. The user picks a value from the dropdown list. The controller uses that value to read some text from a file, and returns that text to the view via the view model. Everything is fine.
THen the user picks another value from the dropdown list. The controller reads a new value from a file and returns it via the view model. Debugging to the LINE BEFORE THE HTML.TEXTBOX is set in the view shows that the model contains the correct value. However, the textbox itself still shows the PREVIOUS value when the page displays!
If I switch from Html.Textbox to a plain input, type="text" html control, everything works fine. That's not so hard, but the same thing happens with my dropdown list -- I can't set the selected value in code. It always reverts to whatever was chosen last. Rendering a "select" tag with a dynamically-generated option list is a pain. I would love to be able to use Html.Dropdown.
What am I missing here?? This is such a simple thing in webforms!
When you post a form, the values that are posted are put into ModelState. When the HtmlHelper renders an html iunput element, e.g. Html.TextBoxFor(x => x.FirstName), it'll search various locations to get the value for the textbox... ModelState is before ViewData.Model in the list of locations. So there for, the previously posted value will appear in your textbox.
To fix this you could clear the ModelState value or update the ModelState value. BUT I would kinda view that as a hacky way of getting around the problem.
The real issue has more to do with the flow of the posts and requests. I would personally look into that and maybe implement the PRG (Post Redirect Get) pattern.
HTHs,

Following on from what Charles/Charlino said:
Model binding updates the ModelState object, which contains validation and model binding errors that are collected during model binding.
Inside an action method, model binding has occurred already to update the model, and generated the ModelState object. If you now update the value on the model inside the action, you must also manually update the model state (since the helpers use it to generate their HTML). Below is an example:
model.CaptchaIsValid = CaptchaService.ValidateAndExpireCaptcha(model.CaptchaAttempt);
if (!model.CaptchaIsValid)
{
ModelState.AddModelError("CaptchaAttempt", "Incorrect - please try again");
}
// I'll clear the value on each attempt, to force them to re-enter a CAPTCHA.
model.CaptchaAttempt = string.Empty;
// Since I updated the model, I must create a new ValueProvider result...
ValueProviderResult clearedValue = new ValueProviderResult(
model.CaptchaAttempt,
model.CaptchaAttempt,
CultureInfo.CurrentCulture);
// ... and update the ModelState's value.
ModelState.SetModelValue("CaptchaAttempt", clearedValue);
The biggest issue I see here is that you are trying to do a postback within MVC. That model is really not supported, and is actually way more trouble than it is worth (as it seems you are finding out). I would recommend using Ajax to update the contents of the dropdown dynamically.
