Need to add a linkbutton control to the header of gridboundcolumn[autogenerated column] of radgrid

[Pradeep Enugala]

Hi Telerik team,

In one of my asp page,i'm displaying the radgrid whose datasource is autogenerated columns[autogeneratedcolumns property is set to true for radgrid].Now my new requirement is ,i need to add a control [Link button]to the header of the each autogeneratedcolumn.
I have tried with ItemDataBound,ItemCreated,ColumnCreated events.
finding the header item in these events and then adding the control to the cell..
 if (e.Item is GridHeaderItem)
        {
            TableCell cell = new TableCell();
            LinkButton lnk_edit = new LinkButton();
            lnk_edit.ID = "lnk_" + e.Column.OrderIndex;
            lnk_edit.Text = "Edit";
            lnk_edit.Width = Unit.Pixel(50);
  cell.Controls.Add(lnk_edit);
}

But unable to add the LinkButton control to the header cell of each column.

Please reply ASAP.

Thankyou,
Pradeep

Hi,

I suppose you want to add a linkbutton to all the boundcolumns. Here is the sample code.
C#:

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

 if (e.Item is GridHeaderItem)

 {

  GridHeaderItem item = e.Item as GridHeaderItem;

 foreach (GridColumn col in RadGrid1.MasterTableView.AutoGeneratedColumns)

 {

  LinkButton link = new LinkButton();

   link.ID = "LinkButton1";

   link.Text = "Edit";
   if (col.ColumnType == "GridBoundColumn")
   {
      item[col.UniqueName].Controls.Add(link);
  }

}

 }

}

Thanks,
Shinu.

i want to do all these things in code behind

Hi Prince,

You can add a template column dynamically as shown below.
C#:

string templateColumnName = "Name";
  GridTemplateColumn templateColumn = new GridTemplateColumn();
  templateColumn.ItemTemplate = new MyTemplate(templateColumnName);
  templateColumn.HeaderText = templateColumnName;
public partial class TemplateColumn : ITemplate
{
 public void InstantiateIn(Control container)
 {
  LinkButton link = new LinkButton();
  link.Text = "Sample";
  link.ID = "LinkButton1";
  link.PostBackUrl = "Page.aspx";
  container.Controls.Add(link);
 }
}

Also check this help documentation which explains more about creating grid from code behind.

Thanks,
Shinu.

hi Shinu
i am very new telerik grid. i don't know much about this
can you please elaborate it little more
i am pasting my code in which i have added columns to it.
now i want to add one more column which has link button in each cell and when you click on that link it pops up another aspx page.
(very similar to AutoGenerateEditColumn) the only problem with autogeneratededitcolumn is it gives inline editing
instead of that i want to pop up another page

thanks

hey shinu
i am able to bring up link buttons in each row. now how do i add querystring to postback url
for example
when i am clicking link button of first row it should navigate to another page with querystring as first row id and first row name which is there in the radgrid table.

thanks
prince

Hi,

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

public static string value;
public partial class TemplateColumn : ITemplate
{
  public void InstantiateIn(Control container)
  {
     Button btn = new Button();
     btn.Text = "Sample";
     btn.ID = "Button1";
     btn.OnClientClick = "OnClientClick(" + value + ");return false";
     container.Controls.Add(btn);
   }
}

JS:

function OnClientClick(value)
{
  var oWnd = radopen("Window.aspx?CustomerID=" + value, "RadWindow1");
}

Thanks,
Shinu.

As to your question, could you please share some more details about the current case? It would be helpful if you provide the markup declaration of the RadGrid (or let us know if it is generated in the code-behind).
