Me again, same problem

[Catalina]

I want to access controls inside RadGrid's EditFormTemplate from page_load (not from RadGrid1_ItemDataBound, RadGrid1_UpdateCommand or any other "events" ), or something like this  ... is this possible?

Hello Catalina,

yes it is possible.
try with below code snippet.

protected void Page_Load(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.EditItems)
        {
            GridEditableItem itemToEdit = (item.OwnerTableView.EditMode == GridEditMode.InPlace) ? (GridEditableItem)item : (GridEditableItem)item.EditFormItem;
            RadGrid RadGrid2 = item.FindControl("RadGrid2") as RadGrid;

        }
}

Thanks,
Jayesh Goyani

Hi Catalina,

Referencing the FormTemplate custom edit form on PageLoad is not the most convenient place to do that. One suggestion is you can access the controls in prerender event as shown below.
C#:

void RadGrid1_PreRender(object sender, EventArgs e)
 {
    foreach(GridDataItem item in RadGrid1.EditItems)
     {
        foreach (GridEditFormItem itemm in RadGrid1.MasterTableView.GetItems(GridItemType.EditFormItem))
        {
           RadGrid grid = itemm.FindControl("RadGrid2") as RadGrid;
        }
     }
}

Also check the following help documentation which explains event sequence of radgrid in detail.
