I am having a problem with the v13.2 WebDataGrid sort and paging on an asp.net web form (IIS v7 & v7.5, .NET 4, 64bit). The page consists of a WebDataGrid and WebHierarchicalDataGrid on the same page. The first grid on the page is the WebDataGrid and it fails the sort and paging every time while the second grid, the WebHierarchicalDataGrid works everytime. Thinking I simply screwed up my code I created a very simple test page with both grids and manually created data. I receive the same error on the WebDataGrid on my test page. I based the test page on Infragistics samples so I figure I have a configuration problem somewhere. The error and stack trace are below. I am running the latest version of Infragistics4.Web.v13.2, updated this morning. The grids are bound server side to a SQL datatable. None of the values in the datatable are null. I have tested this with different combinations of dataviewstate, ajax, etc., even letting Infragistics handle the column specification.

Any feedback is appreciated. This is a serious show stopper for us. Thank you.

This is my current client implementation of the WebDataGrid:

<ig:WebDataGrid ID="wdgPayments" runat="server" AutoGenerateColumns="false" EnableDataViewState="true" EnableAjax="false" DataKeyFields="PaymentID" DataMember="Payment" Width="100%" StyleSetName="Claymation" ClientIDMode="Static" >
<ClientEvents DoubleClick="ShowPaymentDetailsFromDblClick" />
<Columns>
<ig:BoundDataField DataFieldName="PaymentID" Key="PaymentID" Hidden="True"></ig:BoundDataField>
<ig:BoundDataField DataFieldName="PaymentDate" Key="PaymentDate" DataFormatString="{0:MM/dd/yy}" DataType="System.DateTime">
<Header Text="Date"></Header>
</ig:BoundDataField>
<ig:BoundDataField DataFieldName="Description" Key="Description">
<Header Text="Description"></Header>
</ig:BoundDataField>
<ig:BoundDataField DataFieldName="PaymentAmt" Key="PaymentAmt" DataFormatString="{0:c}">
<Header Text="Amount"></Header>
</ig:BoundDataField>
</Columns>
<Behaviors>
<ig:Selection CellClickAction="Row" CellSelectType="None" ColumnSelectType="None" RowSelectType="Single" />
<ig:Sorting SortingMode="Single" />
<ig:Paging PagerMode="NextPreviousFirstLast" PageSize="10" FirstPageText="First" PreviousPageText="Pervious" NextPageText="Next" LastPageText="Last" />
</Behaviors>
<EmptyRowsTemplate>
<div style="padding: 10px;">(No payments were found)</div>
</EmptyRowsTemplate>
</ig:WebDataGrid>
