How to refresh RadGrid after updating data in ItemDataBound event?

[Le Duc Hieu]

hi people!

i wanna rebind my RadGrid after updating data to database, everything works well except that the RadGrid cant rebind data after the action completed, here is my source code.

        protected DataClasses1DataContext context = new DataClasses1DataContext();

        protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
            {
                if ((item["Name"].FindControl("Name") as Label).Text == "Action")
                {
                    var group = (from g in context.Groups where g.Name == "Action" select g).Single();
                    group.Note = "note!";
                    context.SubmitChanges();
                    item.Enabled = false;
                }
            }    
            // i cant call back Rebind() method in RadGrid here because RadGrid does not allow while databinding
        }
i wanna show my data that has been updated in this event but havent still found out the ways to do it yet.
anyone can handle this problem please help me to fix it.

thanks in advance.

kind regards.

Hello Le Duc Hieu,

I strongly recommend that you move this code somewhere else - on Page_PreRender for instance. Using your current approach, you will traverse the whole items collection every time when a grid item is bound. This is not needed and will cause slowdown.
