Hi,

I have a WebDataGrid and was running Infragistics 11.1 2225 but today upgraded to the 2238 service pack and now have an issue.  My WebDataGrid has a number of columns including a template column containing a button.  When I click the button the idea is that a server side function is called which updates the item in the grid and then refreshes the data source for the grid.  This was working fine using :-

protected void btnCompleteTask_OnClick(object sender, EventArgs e)
{
// get the task to be deleted
int taskId = Convert.ToInt32(tbTaskID.Text);
JobTask task = new JobTask(taskId);

// Switch the complete state of the task
task.CompleteTask(!task.Complete, DateTime.Now.Date);

// Best databind again to update the display
JobTaskList listTasks = JobTaskList.GetForJob(_job.Id);
gridTasks.Rows.Clear();
gridTasks.DataSource = listTasks;
gridTasks.DataBind();
}

Now when I run my application and click the button I get an exception as shown below :-

[InvalidCastException: Unable to cast object of type 'Infragistics.Web.UI.GridControls.GridRecordItem' to type 'Infragistics.Web.UI.Framework.UIObject'.]
   Infragistics.Web.UI.TemplateContainer.OnBubbleEvent(Object source, EventArgs args) +94
   System.Web.UI.Control.RaiseBubbleEvent(Object source, EventArgs args) +37
   System.Web.UI.WebControls.ImageButton.OnCommand(CommandEventArgs e) +111
   System.Web.UI.WebControls.ImageButton.RaisePostBackEvent(String eventArgument) +176
   System.Web.UI.WebControls.ImageButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10
   System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +36
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

Am I going to have to back out the update as I can't seem to get this to work anymore.  f I take out the Rows.Clear() call I do not get the exception but neither does the grid row update to reflect the change just made.
