Filter Error: Cast Not Valid

[Mark Galbreath]

I'm using 2009.3.1314 and I have started getting exceptions from the Microsoft AJAX incporated into the control when I try to filter on a column containing numbers.  The column setup in the aspx:

<telerik:GridBoundColumn DataField = "PRICE"
    HeaderText = "PRICE"
    HeaderTooltip = "AMDF Price of new item"
    DataType="System.Int32"
    EmptyDataText="No Data"
    FilterListOptions="VaryByDataType"
    FilterImageToolTip="Use numbers only with filter!"
    ItemStyle-HorizontalAlign = "Right"
    EditFormColumnIndex = "2"
    UniqueName = "price"
    DataFormatString = "{0:c0}">
</telerik:GridBoundColumn>

And when I insert a number in the filter textbox and select, say, "Greater Than," the following error occurs:

A Runtime Error has occurred.

Line 6
Error:Sys.Webforms.PageRequestManagerServerErrorException:
Specified cast is not valid.

Line 6 is the function:

/* START MicrosoftAjax.js */
//----------------------------------------------------------
// Copyright (C) Microsoft Corporation. All rights reserved.
//----------------------------------------------------------
// MicrosoftAjax.js
Function.__typeName="Function";Function.__class=true;Function.createCallback=function(b,a){return function(){
 // 60,000 characters of code
}
Assertion Failed: {0}","invalidOperation":"Operation is not valid due to the current state of the object.","breakIntoDebugger":"{0}\r\n\r\nBreak into debugger?"};
/* END MicrosoftAjax.js */

Is this a bug?

Cheers!

Is the field your filtering actually an integer or is a decimal? I think that might be the issue, the data type must not be matching up.

The database datatype is Oracle number, and I've tried declaring every numeric datatype in the grid column definition with the same result.
