    I'm using the advanced data binding technique from .  However, I need to use GridTemplateColumns to format some of the columns ( <%#String.Format("{0} - {1}", Eval("user"), Eval("name")) %> ) and because I'm using these, nothing comes up.  Is there a way to do this?  If not, is there a better solution?  I did copy the example exactly, but used my datatable instead and it came up, but gave me every single column.  I know I can remove columns, but this doesn't allow me to format columns like I do with GridTemplateColumns.

    Hi William, 

    It would be helpful if you could give us a little more details about the grid settings/markup/code behind. The following code snippet is an example that is bound to DataTable with Dummy data and evaluating of the field is working well.

    <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" CellSpacing="0"
        GridLines="None" Width="800px" OnNeedDataSource="RadGrid1_NeedDataSource">
        <MasterTableView AutoGenerateColumns="False" DataKeyNames="OrderID">
                 <telerik:GridTemplateColumn HeaderText="My Template Column" UniqueName="MyTemplateColumn">
                         <telerik:RadLabel ID="RadLabel1" runat="server"
                             Text='<%#String.Format("You order with id {0} was received at {1}", Eval("OrderID"), Eval("OrderDate")) %>'>

    C# - Code behind:
    protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        RadGrid1.DataSource = GetGridSource();
    private DataTable GetGridSource()
        DataTable dataTable = new DataTable();
        DataColumn column = new DataColumn();
        column.DataType = Type.GetType("System.Int32");
        column.ColumnName = "OrderID";
        column = new DataColumn();
        column.DataType = Type.GetType("System.DateTime");
        column.ColumnName = "OrderDate";
        column = new DataColumn();
        column.DataType = Type.GetType("System.Decimal");
        column.ColumnName = "Freight";
        column = new DataColumn();
        column.DataType = Type.GetType("System.String");
        column.ColumnName = "ShipName";
        column = new DataColumn();
        column.DataType = Type.GetType("System.String");
        column.ColumnName = "ShipCountry";
        DataColumn[] PrimaryKeyColumns = new DataColumn[1];
        PrimaryKeyColumns[0] = dataTable.Columns["OrderID"];
        dataTable.PrimaryKey = PrimaryKeyColumns;
        for (int i = 0; i <4; i++)
            DataRow row = dataTable.NewRow();
            row["OrderID"] = i + 1;
            row["OrderDate"] = DateTime.Now;
            row["Freight"] = (i + 1) + (i + 1) * 0.1 + (i + 1) * 0.01;
            row["ShipName"] = "Name " + (i + 1);
            row["ShipCountry"] = "Country " + (i + 1);
        return dataTable;

    Ultimately you can check out the attached project to see it in action. (Telerik assemblies are excluded to keep the attachment size at minimum).
