<telerik:GridTemplateColumn HeaderText="Starttime" UniqueName="Starttime" >
            <EditItemTemplate>
                <telerik:RadTimePicker ID="rtpStartTime" runat="server">
                </telerik:RadTimePicker>

Hi Waruni,

You can add CompareValidator from code behind as shown below.

CS:

    protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem item = e.Item as GridEditableItem;
            RadTimePicker start = (RadTimePicker)item.FindControl("rtpStartTime");
            RadTimePicker end = (RadTimePicker)item.FindControl("rtpEndTime");

            TableCell cell = (TableCell)start.Parent;

            CompareValidator val = new CompareValidator();
            val.ControlToCompare = start.ID;
            val.ControlToValidate = end.ID;
            val.Operator = ValidationCompareOperator.GreaterThan;
            val.ErrorMessage = "Error message";
            cell.Controls.Add(val);
        }
    }

All the best,
Shinu.
