Enable/Disable telerik:GridButtonColumn

[reza]

Hi
Is it possible to enable/disable icons of telerik:GridButtonColumn in grid rows?
I want to disable "delete icon" for some grid rows through binding expression (or by OnItemDataBound) . 
&
Why this type of column does not support binding expression for

CommandArgument

?
Thank you very much.

Hello,

Please try with below code snippet.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" OnNeedDataSource="RadGrid1_NeedDataSource"
           OnItemDataBound="RadGrid1_ItemDataBound" >
           <MasterTableView DataKeyNames="ID" >
               <Columns>
                   <telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name">
                   </telerik:GridBoundColumn>
                   <telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="~/tempdata/Myphoto.jpg" UniqueName="deleteColumn"
                    CommandName="Delete">
                   </telerik:GridButtonColumn>

               </Columns>
           </MasterTableView>

       </telerik:RadGrid>

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
       {
           if (e.Item is GridDataItem)
           {
               GridDataItem item = e.Item as GridDataItem;

               // Get DataKey - disable image from first row
               string strKey = item.GetDataKeyValue("ID").ToString();
               if (strKey == "1")
               {
                   (item["deleteColumn"].Controls[0] as ImageButton).Enabled = false;
               }

               // Get ColumnValue -- disable image from second row
               string strName = item["Name"].Text;
               if (strName == "bbb")
               {
                   (item["deleteColumn"].Controls[0] as ImageButton).Enabled = false;
               }

           }





       }


protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
       {
           dynamic data = new[] {
             new { ID = 1, Name ="aaa"},
             new { ID = 2, Name = "bbb"},
             new { ID = 3, Name = "ccc"},
             new { ID = 4, Name = "ddd"},
              new { ID = 5, Name ="eee"},
              new { ID = 6, Name ="aaa"},
             new { ID = 7, Name = "bbb"},
             new { ID = 8, Name = "ccc"},
             new { ID = 9, Name = "ddd"},
              new { ID = 10, Name ="eee"}
           };
           RadGrid1.DataSource = data;
       }
