Hi,

I've added the validation for on item request. the GridNumericColumnEditor works ok instantiating the numeric columns. Please send the name for the GridBound column

        protected void GridBlowDown_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridEditableItem && e.Item.IsInEditMode)
            {

                GridEditableItem item = e.Item as GridEditableItem;
                GridNumericColumnEditor editorBldE = (GridNumericColumnEditor)item.EditManager.GetColumnEditor("BlowDownEmissionColumn");
                TableCell cell = (TableCell)editorBldE.NumericTextBox.Parent;

                RequiredFieldValidator validator = new RequiredFieldValidator();
                editorBldE.NumericTextBox.ID = "BlowDownEmission_validation";
                validator.ControlToValidate = editorBldE.NumericTextBox.ID;
                validator.ErrorMessage = "*";
                cell.Controls.Add(validator);

                GridTextColumnEditor editorEventDesc = (GridTextColumnEditor)item.EditManager.GetColumnEditor("EventDescColumn");
                cell = (TableCell)editorEventDesc.Parent;
                validator = new RequiredFieldValidator();
                validator.ControlToValidate = editorEventDesc.ID;
                validator.ErrorMessage = "*";
                cell.Controls.Add(validator);

              
           
            }

        }
