DropDownList inside TELERIX AJAX bound grid doesn't work (all EditorTemplates) ASP.NET MVC2 extensions - asp.net-mvc-2

I have a telerik Grid, AJAX binded.
I've added an EditorTemplate to create a DropDownList.
When I push edit / insert in the grid - I can see the DropDownList, but when I try to use it - it doesn't work.
so I've added an int test to the viewmodel, decorated it with the same UIHINT,
and added it to the view.
The DropDownList works great.
What can cause Telerik's grid to disable that activity ?
I've the same problem with the DateTime component, I get the "button" to show the component, but pressing it yields nothing.
UPDATE: changing the DropDownList from :
Html.Telerik().DropDownList()
.Name("ActivityID")
.BindTo(new SelectList((IEnumerable)ViewData["DropActivities"], "Id", "Name"))
to:
Html.DropDownList(null /* the "name" should be null - proper "name"" attribute will be set by the runtime */,
new SelectList((IEnumerable)ViewData["DropActivities"] /*a list of all employee names */,
"Id", "Name"))
Made it work inside the grid, but... when I try to update, I Get 500 server error.. it looks like the selection doesn't pass well back to the model.

Well, it looks like a confirmed bug with telerik.
Here is the post from their forum: Script Registrar Not Loading Scripts for Controls used in Client Templates
I did applied the patch and it didn't solved the problem waiting for the next version.
EDIT: make sure the bound variable apears only once - that might cause the "lockdown".

How to make a custom ListView page in SuiteCRM

I need to make a page in SuiteCRM (v7.9 -- based loosely on Sugar 6.5 CE) that has a list of objects (of a custom module), with checkboxes in front of each one. So far, so good: that's a standard ListView.
The catch is that only some records should be in the list (filtering on whether there is an associated row in a related custom module/object).
This page needs to be distinct from the "regular" list for this module, which should indeed list all records.
It seems to me it makes sense to use a custom "action" to access this page view, and I can get my custom action code to fire with the right URL.
But I don't see how to hook in the filtering. At first, it looked like the process_record logic hook might be helpful here, but it just gives the bean for every record to be displayed. Unless there's a flag "display this record" that I'm not seeing, that's not so helpful.
Ideally, of course, I'd like to be able to inject a different WHERE clause in my custom controller action before calling
parent::action_listview();
to display the page, but I'm not seeing doc to indicate how that might work. I would include source code, but so far, the line above is everything (but boilerplate) that's in the controller.php file.
Create a copy of listview in custom folder and then override the listview's listViewProcess() method and insert your query there:
function listViewProcess() // generating listview
{
$this->processSearchForm();
if($this->where==''){
$this->where.="leads.status='Converted'";
}
$this->lv->searchColumns = $this->searchForm->searchColumns;
if(!$this->headers)
return;
$this->lv->setup($this->seed, 'custom/modules/Leads/ListView/ListViewGeneric.tpl', $this->where, $this->params);
echo $this->lv->display();
}

Another tested working example can be found here:
How to hard code the where condition in list view ,basic search,advance search in sugar CE
P.S: I'm not so sure about "v7.9 -- based loosely on Sugar 6.5 CE" I'd say it's 95% identical apart from API stuff
for custom modules in SuiteCRM.
You may change in function create_new_list_query.

Microsoft Access Where Condition doesn't works in a subform

I built a form called: "clientlist":
I put a macro with where condition on click:
="IDclient_logindata=" & [Maschere]![clientlist]![IDclient]
this means that when I click on an id client, access will open another form with the respective IDclient. For example if I click on IDclient 3:
it open another form called "client_logindata" filter to IDclient_logindata 3.
Then, I built a navigational form:
using clientlist as subform. But when I click a record, any record, it open every time the client_logindata form with IDclient_logindata form = 1, why it doesn' works in a subform?
Design View of "Navigation Form":
Solved in this way: ="IDclient_logindata=" & [IDclient]
When using a subform, references to controls need to be relative to the main form where the subform is treated as a child control.
Consider adjusting the conditional to the following structure. Do note this is the English version:
="IDclient_logindata=" & Forms!myMainForm!mySubform.Form!mySubformControl
Or specifically tailored to yours (be sure to get exact spelling of all objects):
="IDclient_logindata=" & Forms!NavigationForm!clientlist.Form!IDclient
The OP has found a working solution which is much simpler than what follows. However, I was still interested to see if we could get something on the original model to work, and I'd guess that for users attempting to achieve the same thing using VBA rather than embedded macro's the following may still be useful.
The issue with the code in the original question is that the relevant form isn't open at the 'top level' but as a subform.
Form "normal" subforms, you'd refer to the control on the subform like this:
Forms!navform!clientlist.form!IDclient
Where navform is the name of the outer form. Or in the generalised case, like this:
Forms!Mainform!Subform1.Form!ControlName
However, the "Navigation Form" Wizard, when dragging subforms onto the Add New tab in Layout view doesn't name the subforms nicely. So I had to code it this way:
Forms![Navigation Form]!NavigationSubform.Form!ControlName
To my surprise this code continued to work when I added further forms within the Navigation Forms tabs and had controls named the same as one in question. I guess NavigationSubform automatically points to the tab with the current focus.

ExtJS 4 - How to load grid store with its params carrying latest values from a form?

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.

ASP.NET MVC 2, Ajax.ActionLink resets form data

As I have an editor-list, that needs to have additional edit lines, I found this solution for the problem:
Mvc list editor by Stevens Anderson
this works perfectly, excepts that every time when I add a new line, the whole Form is set back to the default values. You can see the behavior in the demo of the linked page.
Try to edit the value of an input box and then add a new line without saving.
Why isn't it possible just to add a new editor line, without changing any data.
Ok, I've found a workaround
Instead of using the Html.AjaxLink I am now using a custom JavaScript function with jQuery
function newProjectExpenseRow() {
jQuery.get("/Controller/Action", function (response) {
$(response).insertBefore("#id");
});
}
it now gets the Control from the controller/action and inserts the result before the #id element

MVC Html.textbox/dropdown/whatever won't refresh on postback

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,
Charles
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.
