validator callout extender

Posted By: sriram     Posted Date: October 08, 2009    Points:2   Category :ASP.Net
iam using customvalidator with validatorcalloutextender. i'm changing the errormessage of the cusomvalidator based on different conditions using javascript function. but the errormessage is not changing. whatever the value that is given for errormessage attribute , that one only displaying. Even the text box value is < 3000 or > 5000, always 'test1' is only displaying in validatorcalloutextender, instead it should display test2, if the value in textbox is less than 3000, and should display test3 , if its greater than 5000.

<asp:CustomValidator ID="cv_RC_ValidTotQty" runat="server" ErrorMessage="test1"
ControlToValidate="txtTotalQty" ClientValidationFunction="validateTotalQtyForRC" Display="None" ValidateEmptyText="true" SetFocusOnError="true" ValidationGroup="Submit"></asp:CustomValidator>
<ajaxToolkit:ValidatorCalloutExtender id="vceValidRCTotalQty" runat="server" TargetControlID="cv_RC_ValidTotQty" ></ajaxToolkit:ValidatorCalloutExtender>

function validateTotalQtyForRC()
if(parseInt(totQty) < 3000)
oSrc.errormessage = "test2";
args.IsValid = false;
else if(parseInt(totQty) > 5000)
oSrc.errormessage = "test3";
args.IsValid = false;

Hi try like this

sender.errormessage = "Your message";
var cell = sender.ValidatorCalloutBehavior._errorMessageCell;

if (cell != null)
cell.innerHTML = "Test Message";

Also send the object at the client side using this keyword when you are calling the javascript function from custom validator
