RadComboBox in a NestedViewTemplate of RagGrid

[Carlos Amigo]

I have a rather complicated scenario:
-> Ragdrid (Grouped Data)
    -> NestedViewTemplate
        -> RadGridDetail (Ungrouped or Detail of data, here users can edit data)
            -> GridTemplateColumn
                -> EditItemtemplate
                    -> RadComboBox (For insert or update)
                    -> Imagebutton (open RadWindow)

On insert or update, the ImageButton is enabled and open a RadWindow, with a CRUD of a table that populate the RadComboBox.
When I run any command of CRUD, I need to reload all items of RadComboBox. How I can to do this? (or where can I find info about this?)

Thank in advance

Hello Carlos,

If you want to access the RadComboBox inside EditItemTemplate of inner Grid, first access the EditForm and then get the control like below.

C#:

GridEditFormItem editedItem = (GridEditFormItem)RadGridDetail.MasterTableView.GetItems(GridItemType.EditFormItem)[0]; // get the edit form of inner Grid
 RadComboBox combo= (RadComboBox)editedItem.FindControl("RadComboBox1"); //accessing RadComboBox in edit form
//reload combo

Thanks,
Princy.

Princy: Thank you for your feedback. I've another questions about this.
In your code...

GridEditFormItem editedItem = (GridEditFormItem)RadGridDetail.MasterTableView.GetItems(GridItemType.EditFormItem)[0]; // get the edit form of inner Grid
RadComboBox combo = (RadComboBox)editedItem.FindControl("RadComboBox1"); //accessing RadComboBox in edit form

...you started with RadGridDetail, and this object, is inside of RadGrid1 (nested grids).
How I can to obtain my RadGridDetail for the selected, (opened) RadGrid1 row?
How I can refresh my RadComboBox1 when RadWindow close? (RadAjaxManager.AjaxRequest?)
Have you any "code snippet"?
Thank you.
