I'm trying to bind the UltraWebtree to a WebHierarchicalDataSource using 2 sqldatasources. Practically I'm, following the sample of the sample website. (http://samples.infragistics.com/2008.2/webfeaturebrowser/WebHierarchicalDataSource/UltraWebTreeBinding.aspx)
I'm getting this error
Please verify that the DataFile or Data property has been set on the XMLDataSource.
[Exception: Please verify that the DataFile or Data property has been set on the XMLDataSource.] Infragistics.WebUI.UltraWebNavigator.UltraWebTree.BindTopLevelNodes(Node node, String nodeId) +448 Infragistics.WebUI.UltraWebNavigator.UltraWebTree.PerformDataBinding() +584 System.Web.UI.WebControls.HierarchicalDataBoundControl.PerformSelect() +85 System.Web.UI.WebControls.BaseDataBoundControl.DataBind() +73 System.Web.UI.WebControls.BaseDataBoundControl.EnsureDataBound() +82 System.Web.UI.WebControls.BaseDataBoundControl.OnPreRender(EventArgs e) +22 Infragistics.WebUI.UltraWebNavigator.UltraWebTree.OnPreRender(EventArgs e) +38 System.Web.UI.Control.PreRenderRecursiveInternal() +80 System.Web.UI.Control.PreRenderRecursiveInternal() +171 System.Web.UI.Control.PreRenderRecursiveInternal() +171 System.Web.UI.Control.PreRenderRecursiveInternal() +171 System.Web.UI.Control.PreRenderRecursiveInternal() +171 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +842
What's wrong here ?
Hi ....i m facing the same problem
while running the code from the link:
http://help.infragistics.com/Help/NetAdvantage/ASPNET/2010.1/CLR3.5/html/WebHierarchicalDataSource_Using_WebHierarchicalDataSource_in_Code.html
Can u please let me know eloborately what i should bo to solve the above error.
I had masterpage with script manager and content page without proxy but that was not the solution if I remember it right.
Are you using the Hier.datasource with a UltraWebTree ? Because then you can't set DataKey you have to use
protected void UltraWebTree1_NodeBound(object sender, WebTreeNodeEventArgs e) { e.Node.DataKey = Set data key in this event instead of UltraWebTree.Datakey ; }
What was the solution then? I'm having the same error. Why is there no reply from infragistics 'support'?
Solved, had something to do with an update panel, although the error message had me searching in other places for a while...
