assigning grid view hyper link button command argument

[usman]


<telerik:RadGrid ID="RadGrid1" runat="server" Skin="Sitefinity"

           onitemcommand="RadGrid1_ItemCommand"

           onitemdatabound="RadGrid1_ItemDataBound1" >

           

       <MasterTableView AutoGenerateColumns="false" GridLines="None">

        <Columns>

        

       <telerik:GridButtonColumn DataTextField="firstname" UniqueName="col1" ButtonType="LinkButton" CommandName="detail"></telerik:GridButtonColumn>

         

        </Columns>

         

     

     

</MasterTableView>

 

           <HeaderContextMenu EnableAutoScroll="True">

           </HeaderContextMenu>

 

       </telerik:RadGrid> 

Now I want to assign the command argument of GridButtonColumn   with id(pk) from my db table,

so that every row is corresponding to an id which I can access later withour shpwng on the grid view

I tried another approach but got errors ,I wrote this code 

'<telerik:GridButtonColumn DataTextField="firstname" UniqueName="col1" ButtonType="LinkButton" CommandName="detail" CommandArgument= '<%#Eval("MemberID") %>' ></telerik:GridButtonColumn>'
I got these 2 errors 
'Error 20 Databinding expressions are only supported on objects that have a DataBinding event. Telerik.Web.UI.GridButtonColumn does not have a DataBinding event. Line   43'


'Error 21 Literal content ('</telerik:GridButtonColumn>') is not allowed within a 'Telerik.Web.UI.GridColumnCollection'.  Line 45'

Hello Usman,

Try the following code to access the ButtonColumn and assign CommandArgument.
c#:

protected void RadGrid1_ItemDataBound1(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
    LinkButton btn = (LinkButton)item["col1"].Controls[0];
    btn.CommandArgument=//assign the argument here
    }
}

            GridDataItem item = e.Item as GridDataItem;

            // using columnuniquename
            string str1 = item["Name"].Text;

            // using DataKey
            string str2 = item.GetDataKeyValue("ID").ToString();
