Hello,

Try the following code.
C#:
protected void grid_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridDataItem)
 {
  GridDataItem item = (GridDataItem)e.Item;
  TableCell cell = (TableCell)item["UniqueName"];
  if (cell.Text == "text")
  {
   ImageButton img = (ImageButton)item.FindControl("ImageButton1");
   img.ImageUrl = "~/Images/img.gif";
  }
 }
}

Thanks,
Princy.

Hi Princy,

I am not getting the value.
Bellow is my code.
.aspx
                            <telerik:RadGrid ID="grdInbound" runat="server" AutoGenerateColumns="false" AllowSorting="True"
                                Width="100%" OnItemCommand="grdInbound_ItemCommand1" AllowAutomaticDeletes="True"
                                OnItemCreated="grdInbound_ItemCreated"
                                onitemdatabound="grdInbound_ItemDataBound">
                                <HeaderStyle BorderStyle="Solid" Font-Bold="true" HorizontalAlign="Center" />
                                <ItemStyle HorizontalAlign="Left" Font-Underline="false" />
                                <AlternatingItemStyle HorizontalAlign="Left" Font-Underline="false" />
                                <MasterTableView CommandItemDisplay="Bottom" TableLayout="Fixed" EditMode="InPlace">
                                    <Columns>
  <telerik:GridTemplateColumn HeaderText="Comment" UniqueName="comment"  DataField="COMMENT">
                                            <ItemStyle HorizontalAlign="Center" Width="8%" />
                                            <HeaderStyle Width="8%" />
                                            <ItemTemplate>
                                                <asp:ImageButton ID="imgComment" runat="server" ImageUrl="~/images/No_Comments.jpg"
                                                    Width="20px" Height="20px" CommandArgument='<%# DataBinder.Eval (Container.DataItem, "COMMENT") %>' />
                                                <telerik:RadToolTip runat="server" ID="RadToolTip1" Width="160px" Height="40px" IsClientID="false"
                                                    Visible="false" SkinID="Forest" TargetControlID="imgComment" Text='<%# DataBinder.Eval (Container.DataItem, "COMMENT") %>'

                                            </ItemTemplate>
                                        </telerik:GridTemplateColumn>
 </Columns>
  </MasterTableView>
                            </telerik:RadGrid>

.aspx.cs

            if (e.Item is GridDataItem)
            {

                TableCell cell = (TableCell)item["comment"];
                if (string.IsNullOrEmpty(cell.Text))
                {
                    ImageButton img = (ImageButton)item.FindControl("imgComment");
                    img.ImageUrl = "~/images/No_Comments.jpg";

Hello,

Based on the declaration of RadGrid you have post I see that you have one template column. And in the ItemTemplae of this column you have defined the ImageButton control. In this case the cell text is blank, because the ItemTemplate replaces the cell content with the control that is defined in it. In this case you need to use not the GridDataItem object but its corresponding DataItem object, namely:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
   {
       if (e.Item is GridDataItem)
       {
           GridDataItem item = (GridDataItem)e.Item;                       
           if (string.IsNullOrEmpty(DataBinder.Eval(item.DataItem, "COMMENT").ToString()))
           {
               ImageButton img = (ImageButton)item.FindControl("ImageButton1");
               img.ImageUrl = "~/Images/img.gif";
           }           
           else
           {
               ImageButton img = (ImageButton)item.FindControl("imgComment");
               img.ImageUrl = "~/images/Comments.jpg";
           }
       }
   }

Give this suggestion a try and check whether this is the desired behavior.
