How to force WHDG to refresh from datasource?
posted

Hi,

My Web Hierarchical Data Source, WHDS, is from two SQL datatables and defined entirely in C#.  I'm using .NET 2.0.

Does anyone know how to force the WHDG to refresh/reload when I want, on a postback?  I'm changing the database from the page, adding and removing rows, but I can't figure out how to get the WHDG to reload and show current data.  All of my inserts/deletes are outside the grid: no direct editing is being done.

Any assistance would be terrific!  Thx.

Charles

           // in a method that I call in page_load and selectively on a postback

           // ... just reloaded my two datatables from SQL stored procedures

           // Declare the datatables as the datasources of the parent and child dataviews of my WHDS
            myWebHierarchicalDataSource.DataViews.FindByID("parent").DataSource = myDataTable;
            myWebHierarchicalDataSource.DataViews.FindByID("child").DataSource = myDataTable2;

            // Now force a rebind of my WHDG
            this.myWHDG.Rows.Clear();
            this.myWHDG.DataBind();
