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.
