[Solved] How to get a Handle to a Control Inside a Formtemplate of a RadGrid

[Suresh Mishra]

Hi,

I am trying to access a dropdown call "DropdownlistOuter" so I can attach a data source to it AFTER a row is put in edit mode. 
How do I get a handle to this control at run time when the Edit link is pressed.

Thanks!

Suresh

Here is the relevant aspx script.

Hi,

Try the following code snippet to achieve the desired scenario.

CS:

 protected void RadGridEmpData_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            DropDownList ddl = (DropDownList)editItem.FindControl("DropdownlistOuter");
            // populate the DropdDown here
            //ddl.DataSourceID = "SqlDataSource1";
            //....
        }

     }

Thanks
Princy
