Hi,

I'm using the UltraWebGrid, using LoadOnDemand="Xml" for async postbacks.  I have a datatable I keep in the codebehind that I populate when the user requests the grid be filled.  When generating the table, I add a boolean column directly to it as a "selected" indicator.  The reason for this is the UI layout desired is a check box for rows that we will ultimately perform actions on.

Now most of the grid is set with AllowUpdates=false, however this "Selected" column allows updates. Additionally, the grid is set up with Paging.

My desired functionality would be that the customer could click the check box on a few columns, each would get marked, allow the user to go to another page then come back and still see the same items selected.

To achieve this, I subscribe to the UpdateRow event on the grid, putting in the logic to find the row in the data table, update it, and then save it.  Unfortunately, this causes a postback on every click which also presents the user with a "Please Wait" image (set on grid initialize) which is less than desireable.

When I switch to subscribe to UpdateRowBatch, I found the grid doesn't fire this event for me when I change pages, ultimately meaning any selections are lost when switching from page to page.

I've tried catching the ClientSideEvents of afterCellUpdate or BeforeRowUpdate and calling igtbl_cancelPostback, while using UpdateRow, but this doesn't actually prevent a post back.  I've also tried igtbl_needPostback for UpdateRowBatch, but don't get one.

I've also tried using igtbl_doPostBack during BeforeXMLHttpRequest while subscribed to UpdateRowBatch, everything fires as expected, however this ultimately fires a full postback, so clicking from page 1 to page 2 results in a quick display of page 2, followed by a full page postback and back to page 1.

Any suggestions for how I can get the UpdateRowBatch functionality (of a single batch postback) to fire when changing pages?  Maybe there's some way I'm missing to request the grid invoke UpdateRowBatch on page OR postpone postbacks for UpdateRow if a specified column is all that changed?

 Thanks in advance for any help you can offer!
