How to fire a server event when cell's value has changed ?
posted

Hi,

In my project, I need to do somethings from server side when value of a cell has been changed.

So what is the event I should use for this situation? I could not find event like CellValueChanged in DataGridView from Microsoft.

Thanks

    I've used UpdateCell() function for this situation. But I got a problem.

    When i set LoadOnDemand=Xml, An Error has occured when I change value of cell

    [NullReferenceException: Object reference not set to an instance of an object.]
       Infragistics.WebUI.UltraWebGrid.UltraWebGrid.RaiseCallbackEventHandler(String eventArgument) +9605
       Infragistics.WebUI.UltraWebGrid.UltraWebGrid.LoadPostData(String postDataKey, NameValueCollection values) +1285
       System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +693
       System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1743

    Could you help me on this issue?

    Thanks
