Disable GridDropDownColumn In InPlace Edit Mode

[Larry]

I have a grid with a GridDropDownColumn.  EditMode is "InPlace".  On Insert I want to access the GridDropDownColumn...no problem there..but when the Grid is in Edit mode I want to disable the dropdown.  How do I go about doing this?
Thanks,
Larry

Hello Larry,

You can try the following code snippet to disable the DropDownColumn in Editmode when the EditMode is InPlace.

ASPX:

 <telerik:GridDropDownColumn DropDownControlType="DropDownList" UniqueName="GridDropDownColumn" HeaderText="GridDropDownColumn">
 </telerik:GridDropDownColumn>

C#:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
       if (!(e.Item is GridDataInsertItem) && e.Item.IsInEditMode)
        {
            GridEditableItem editItem=(GridEditableItem)e.Item;
            DropDownList drList = (DropDownList)editItem["GridDropDownColumn"].Controls[0];
            drList.Enabled = false;
        }
    }

Thanks,
Princy.

Hello Ravi,


For accessing any control placed in template field, use the FindControl() method of the GridItem. The sample will help you.

Code:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (!(e.Item is GridDataInsertItem) && e.Item.IsInEditMode)
    {
        GridEditableItem editItem = (GridEditableItem)e.Item;
        DropDownList drList = (DropDownList)editItem.FindControl("DropDownList1");
        drList.Enabled = false;
    }
}

And the mark-up is:

<telerik:GridTemplateColumn HeaderText="EditTemplate">
    <EditItemTemplate>
        <asp:DropDownList ID="DropDownList1" runat="server">
        </asp:DropDownList>
    </EditItemTemplate>
    <ItemTemplate>
        . . .
    </ItemTemplate>
</telerik:GridTemplateColumn>

Also, go through the documentation: Distinguish edit/insert mode on ItemCreated/ItemDataBound

Thanks for reply.
But how dropdown contols show in grid view, means that how grid goes in Edit State..
