protected void radDeferredIncome_ItemCreated(object sender, GridItemEventArgs e)

                GridEditableItem item = e.Item as GridEditableItem;

                GridTextBoxColumnEditor editor = (GridTextBoxColumnEditor)item.EditManager.GetColumnEditor("AdvanceVarianceComment");

                TableCell cell = (TableCell)editor.TextBoxControl.Parent;

                GridNumericColumnEditor proposed = (GridNumericColumnEditor)item.EditManager.GetColumnEditor("ProposedAdvanceTargetAmount");

                GridNumericColumnEditor expected = (GridNumericColumnEditor)item.EditManager.GetColumnEditor("ExpectedAdvanceTargetAmount");

                CustomValidator val = new CustomValidator();

                editor.TextBoxControl.ID = "AdvanceVarianceComments";

                val.ControlToValidate = editor.TextBoxControl.ID;

                val.ErrorMessage = "*";

                val.Attributes.Add("proposed", proposed.NumericTextBox.ClientID);

                val.Attributes.Add("expected", expected.NumericTextBox.ClientID);

                val.ClientValidationFunction = "advanceVarianceValidation";

                cell.Controls.Add(val);

            }

        }  

I am using in-grid editing. I am passing in 2 attributes that are the clientId's of the 2 textboxes i need to compare.  Basically, If the difference 

between the 2 textboxes is not zero and a comments textbox is blank that the row is not valid.



The javascript is below.






<

 

telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
 
 

<script type="text/javascript" language="javascript">
 


 

function advanceVarianceValidation(sender, args) {
 
 

var isValid = true;
 
 

var proposed = document.getElementById(sender.attributes["proposed"].value).value;
 
 

var expected = document.getElementById(sender.attributes["expected"].value).value;
 
alert(proposed + 

',' + expected);
 
 

if ((proposed - expected) != 0) {
 
 

if (args.value == null || args.value.length == 0) {
 
isValid = 

false;
 
} 
}
 
args.IsValid = isValid;
}
 

</script>
 


 

</telerik:RadCodeBlock>





This works if i am editing the first row but the validation does not fire if i am editing any other.



Anyone have any ideas.







Thanks,





John
