I have searched the forum, infragistics site, and google and found no examples on how to bind an entity collection to the WebHierarchicalDataGrid. Is this even possible? I have had troubles with their older grids in the past (UltraWebGrid) and completely gave up after reading on here that infragistics was missing something that prevented proper binding to the EntityCollection. I was hoping that their newest version has learned to play nicely as it seems this problem comes up often.
I've tried to bind this a few different ways and I just end up with a series of meaningless exceptions such as:
[InvalidOperationException]
Infragistics.Web.UI.GridControls.WebHierarchicalDataGrid.DataBind() +749
Infragistics.Web.UI.GridControls.WebHierarchicalDataGrid.EnsureDataBound() +35
Infragistics.Web.UI.Framework.Data.HierarchicalDataBoundControlMain.OnPreRender(EventArgs e) +89
Infragistics.Web.UI.GridControls.WebHierarchicalDataGrid.OnPreRender(EventArgs e) +13
System.Web.UI.Control.PreRenderRecursiveInternal() +103
System.Web.UI.Control.PreRenderRecursiveInternal() +175
System.Web.UI.Control.PreRenderRecursiveInternal() +175
System.Web.UI.Control.PreRenderRecursiveInternal() +175
System.Web.UI.Control.PreRenderRecursiveInternal() +175
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +2496
I've posted for help on the infragistics forum as well, but I know you guys are much more on top of your game. If you happen to have a resource that can help me, I would appreciate it.
