Code on page one view:
#foreach($customers as $customer)
edit
#endforeach
On page one controller
function edit($id){
$customer1 = Customer::find($id)->get();
return view('page2', compact('customer1'));
}
My route on web.php
Route::get('page2\{id}', page1controller#edit);
Now the thing is id is a primary key so there's no cases of redundancy. However I am getting all the multiple records(all records) on the next page.
On page2 I need to display value related to the customer clicked on the first page although its showing me all the records
I checked my db there is no redundant ids.
On the find() function don't put the ->get(), that's why it returns all values of the Customer model.
Check docs here about that function.
I think you need to remove ->get() entirely.
Instead of using find($id)->get();, use find($id);
it should look like below.
function edit($id){
$customer1 = Customer::find($id);
return view('page2', compact('customer1'));
}
This should return the customer whose id is passed as the parameter

Here I have selected 2nd and 5th row, I also have a button named Send Requests in the section part which is highlighted. If I click this button it calls a javascript controller function which is defined in the extensions of the application. In this js function how can I retrieve the selected rows that are selected?
I have enabled the checkboxes in this page by mentioning this code
"settings": { "gridTable": false, "multiSelect": true } in the manifest.json
As it was recommended by this link https://sapui5.netweaver.ondemand.com/#docs/guide/116b5d82e8c545e2a56e1b51b8b0a9bd.html
I want to know how can I retrieve the rows which got selected?
There is an API that you can use for your use case. It is described here: https://sapui5.netweaver.ondemand.com/#docs/guide/bd2994b69ef542998becbc69ab093f7e.html
Basically, you just need to call the getSelectedContexts method. Unfortunately you will not be able to really get the items themselves, only the binding contexts (which point to the data entities which are selected). Excerpt from the documentation:
After you have defined a view extension, you can access and modify the
properties of all UI elements defined within these extensions (for
example, change the visibility). However, you cannot access any UI
elements that are not defined within your view extensions.
In this type of table there is way.
var myTable=sap.ui.getCore().byId("your table id");
get all rows:
var myTableRows=myTable.getRows();
now get selected Indices
var selectedIndeices=myTable.getSelectedIndices(); //this will give you array of indeices.
now run loop on indeices array. And get particular row item;
// get binding path
var bindingpath=myTableRows[2].getBindingContext().sPath; // this will return eg:"/ProductCollection/2"
// now get Binding object of that particular row.
var myData=myTableRows[2].getModel().getObject(bindingpath); // this will return binding object at that perticular row.
// once your loop is over in the end you will have all object of selected row. then do whatever you want to do.
If you use smart template create an extension.
This is the standard event befor the table is rebinding:
onBeforeRebindTableExtension: function (oEvent) {
this._table = oEvent.getSource().getTable();
}
In your action function (or where you want) call the table and get the context :
this._table.getSelectedContexts();
in my myForm I call in a tableMY a displayMethod_fieldA.
In myForm I insered a some date in a DateEdit and I want to make a selection in table using the entered value. If I crete a displayMethod whit parameter I have an error.
Look like this code I get error:
display myEDTField displayMethod_fieldA (date _dateFromForm)
{
tableMY table;
select table
where table.item == this.item
&& table.dateTable == _dateFromForm;
return table.valueFieldA;
}
I have an error looklike this:
The display method has an incorrect parameter profile.
There is another way to display or set the value in my StrinEdit in Grid by method passing a parameter?
In web I saw the method modifier modifierMothod , but I need some more explanation. I don't know if this method is a right way.
Display methods are not designed with this feature.
display method for a table, form, report, or report design does not
have any parameters. For example: display Amount amount()
A display method for a form data source does require a parameter. You
use the
parameter to specify a table buffer. The type of the table buffer has
to match the type of the table in the form data source.

You can create the desired behaviour with an edit method (and setting the field to AllowEdit(false) or enabled(false).
I have a problem with my front end admin update page. How can I retrieve values from a SiteTree page and populate it into a custom form? Is the setValue($values) function the only way? If yes, which is the best method to get the page variable?
I am using this:
$evens = Versioned::get_by_stage('PageCalendrierEvenement', 'Stage')->byID($evenID);
I'm getting values from an ID of a draft page. After I get variables and values like that:
$field = new TextField('Titre', 'Titre');
$field->setValue($evens->Titre);
or
new TextField('Titre','Titre', $evens->Titre);
Which is the better solution?
The solution is 2 part:
Use TextField::create($constructor, $args) instead of new (optional, but not doing so is a pet hate of mine).

I am using GWT 2.4 and I have an EditorGridPanel in my page for which I want to have a onload functionality. Actually after grid is loaded with rows, I would like populate my form fields with first row values automatically. How can write a listner/handler to execute this logic in gwt.
When your passing datastore values to grid.. try to get first record
store.getModels(); or store.getAt(index) or getRecordAt(index)
once you got record check not null and set values in form.
You can do this after gird loaded by set timer to some milliseconds delay. is this you need..
You don't need a handler for this. Typically, you would have an Activity or Presenter that drives these actions. When you receive your data from a server, you would do something like:
myView.populateMyGrid(ArrayList<MyObject> objects);
myView.populateMyPanelWithFirstRow();
Alternatively, you can add this to the method which populates your grid:
displayItems.addAll(objects);
populateMyPanelWithFirstRow(displayItems.get(0));
Actually when I call loadGrid method on my grid to load rows, it is taking some time to load it (because data has to come from database, but by that time the client code to populate form field with row data which is written after loadGrid method is getting executed and it ended up with not populating anything in my form field as the grid was empty by that time.
So, what I did was that I have added a listener(addStoreListener) to the store of my grid like below and written my logic inside the onLoad method, it worked perfectly.
myGrid.getMyStore().addStoreListener(new StoreListenerAdapter() {
public void onLoad(Store store, Record[] records) {
...
}
});
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.
