Dears,
In radGrid Template I have radcombobox and a button, when user clicks the button I open a radwindow to let hime insert new choice, if user click ok in the radwindow dialog I have to add a new item to radcombobox item.
I am call javascript function in the main page from the dialog. this function fire the ajaxRequest of RadAjaxManger.

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest();


In the ajaxrequest handler I tried to get the radcombobox of the radgrid template as following:

Dim GridItem As GridDataItem = CType(grdTrngs.EditItems(0), GridDataItem)

Dim cmbDocs As RadComboBox = GridItem.FindControl("cmbTrngsHR_DOCS_ID")

Hello Pavlina,
I could not find the answer, because the examples in the links are accessing the RadGrid Editing Template's controls via e (event argument), unfortunately I can’t do that because I need to update the radcombobox items after RadWindow closing so I am calling a javascript function in the main page from the dialog. This function fires the ajaxRequest of RadAjaxManger.

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest();

the event arguments of ajaxRequest handler don't have any reference to RadGrid Editing Template's controls.

In my case I have to access the controls without using any event arguments, So I added this thread.

Thanks in Advance
Best Regards

Hello,

Check out the following code library submission which explains on how to access the controls embedded inside templates in the grid:

Dears,
I found and used the Telerik.Web.UI.RadComboBox.ComboBoxes.
In my case I have a radgrid template with one RadComboBox, when I call Telerik.Web.UI.RadComboBox.ComboBoxes (of course in the client side) it returned the RadCombobox control and I managed to update its items.
I tried to get more information about this useful array, but I couldn't. every thing I found was in:
http://www.telerik.com/help/aspnet-ajax/combo_clientsidebasics.html
I need to know:
- If it returns all Radcomboboxes in the RadGrid template, and what it will return if I have to RadGrid and each one of them has its template with more than one combo ?
- Does it return just Radcomboboxes in RadGrid templates ?

Thanks in Advance
Best Regards

Hello Bassel,

Telerik.Web.UI.RadComboBox.ComboBoxes can be used to obtain an array containing all the client-side combobox instances. You can review the help articles below for additional information.
