I have a RadCombo box inside Radgrid , i need to get that Control in CodeBehind and Populate it Programatically ,
I tried using the Radgrid.FindControl() method but it is returning Nothing ..

 

Dim Cmb As New Telerik.Web.UI.RadComboBox

 

Cmb =

CType(gvSort.FindControl("ColName"), RadComboBox)

Hello Liji Lose,

You can access the RadComboBox in ItemDataBound event of grid and then populate it.

C#:

    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            RadComboBox combo = (RadComboBox)item.FindControl("ColName");
            // Populate the combo
        }
    }

Thanks,
Princy.

The Controls inside the RadGrid ItemTemplate can only be Accessed inside  ItemDataBound Event ?

Hi Liji,

You can try handling the RadGrid ItemCommand event for your purpose as well. For instance as below:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.ExpandCollapseCommandName && !e.Item.Expanded)
    {
        GridDataItem item = e.Item as GridDataItem;
        GridNestedViewItem nestedItem = item.ChildItem;
        RadComboBox comboBox = nestedItem.FindControl("ColName") as RadComboBox;
    }
}

I hope this helps.
