Hi Hanaa,

Please try the following code snippet to hide a column in the detailtable.

ASPX:

<telerik:GridTemplateColumn HeaderText="HyperLInkColumn">
  <ItemTemplate>
      <asp:HyperLink ID="HyperLink1" runat="server">HyperLink</asp:HyperLink>
  </ItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Posts")
  {
    GridDataItem item = (GridDataItem)e.Item;
    HyperLink hyperlnk = (HyperLink)item.FindControl("HyperLink1");
    if (item["UserID"].Text == "some value")// Your condition goes here
    {
      hyperlnk.Visible = false;
    }
  }
}

Thanks,
Shinu

Hi Hanaa,

Make sure that you have set the Name property of the GridTableView to "Posts". Please provide your code snippet if this doesn't help.

ASPX:

<telerik:GridTableView  Name="Posts">
