How to find Grid ExpandCollapseColumn Header in Code ?

[Jai]

Hi,

I have one situation where i want to find the header of Grid and apply the custom css. In grid I have following column and want to get the header of this column in code
            <ExpandCollapseColumn Visible="True">
            </ExpandCollapseColumn>
                <telerik:GridTemplateColumn UniqueName="AssociateColumn">
                    <ItemTemplate>
                        <asp:HyperLink ID="Lnktest" runat="server" Text="test"></asp:HyperLink>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>

I have follwoing code to get the header and i am able to get that for other columns but not for this above column.

if (e.Item is GridHeaderItem)
            {
                GridHeaderItem item = (GridHeaderItem)e.Item;
                foreach (GridColumn col in GridAttorney.MasterTableView.Columns)
                {
                    if (col is GridEditCommandColumn || col is GridButtonColumn)
                    {
                        item[col.UniqueName].CssClass = "gridsBlankheadercolumn";
                    }
                }
            }

Can anyone tell me How to get this Column header in this above code ? Also please see the attached screenshot for better understanding.

Thanks,

Hello Jai,

Try the following code snippet to achieve your scenario.
C#:

foreach (GridColumn col in RadGrid1.MasterTableView.Columns)

     {

        if ( col is GridTemplateColumn)//checking for template column

          {

            // set css from here


          }

       if (col is GridExpandColumn)//checking for ExpandColumn

          {

             //set css from here

          }

    }

Thanks,
Shinu.

Hello Jai,

Try traversing the RenderColumns or AutoGeneratedColumns collection instead of Columns.

Hi Lana,

Can you please give me some more detail here or What do you mean by traversing the RenderColumns or AutoGeneratedColumns collection ?

Hi Jai,

Just replcate Columns with AutogeneratedColumn or RenderColumns in your code:

foreach (GridColumn col in RadGrid1.MasterTableView.AutogeneratedColumns)
{
    if ( col is GridTemplateColumn)//checking for template column
    {
        // set css from here
    }
    if (col is GridExpandColumn)//checking for ExpandColumn
    {
        //set css from here
    }
}
