Hi!

I want to access the controls such as dropdown and textbox defined in editformsettings of GridTableView in code behind to populate the values from database when the user clicks on add new record on the GridTable View.. right now i cant access those controls ... like we do in this code
if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
            {
                GridEditFormItem edititem = (GridEditFormItem)e.Item;
                DropDown txt = (DropDownedititem.FindControl("Dro");//access the DropDown in FormTemplate
            }
but i want to do when user clicks on add new record, so i extract value from RadGridDataKeyValue and select value from database and populate the controls inside GridTableView ...
note : i want to bind drop down in code behind not in html file..

Hello Winston,

You can differentiate between the grid rows in hierarchy by using GridTableView Name property. Here is the code sample.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted && e.Item.OwnerTableView.Name == "Runs")

{

GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;

TextBox txt = (TextBox)insertItem.FindControl("TextBoxRunCode");

}

Also the documentation shows different ways to distinguish grid rows in hierarchy on ItemCreated/ItemDataBound .

Check out the documentation to know more about distinguishing edit/insert modes on ItemCreated/ItemDataBound:
http://www.telerik.com/help/aspnet-ajax/grddistinguisheditinsertmodeonitemcreateditemdatabound.html

Thanks,
Princy.
