Help Plz...
grid.invokeXmlHttpRequest() doesn't work for Hierarchical Grid.
Grid.Browser = BrowserType.Xml;
Grid.DisplayLayout.LoadOnDemand = LoadOnDemand.Xml;
The grid has to handle the following events: InitializeDataSource, XmlHTTPRequest.
In your javascript event for a new requested page (or new reqeusted data) you can use the CSOM for the grid to get the grid and then call grid.invokeXmlHttpRequest(). Read the online documentation about all the different options for the invokeXmlHttpRequest method. Calling that method will trigger the XmlHTTPRequest event and from there you can do all your work to get your data from the database. When you bind it be sure to bind the grid to null before you bind it to the new dataset or else all the new rows may not show up. When you set the new DataSource to the grid there's no need to call .DataBind() afterwards.
Hope this helps.
