Hallo,  this is my first post and sorry for my english (google-translate for ever)..

There are a problem with Load on Demand wenn i built it on runtime.

I got an 2-level WebHierarchicalDataGrid, 2 SqlDataSources and WebHierarchicalDataSource with default properties.

I make binding at runtime, in WebHierarchicalDataGrid_Init Funktion.

If i set InitialDataBindDepth="-1" it works properly (no Load on Demand).

If i set InitialDataBindDepth="0", after expanding of ParentRow is result of ChildDataView duplicated.

 

Here is my Code:

Protected Sub hdgAgentWork_Init(sender As Object, e As EventArgs) Handles hdgAgentWork.Init

 ' Create the view

Dim viewOfDay As New Infragistics.Web.UI.DataSourceControls.DataView()

Dim viewOfWeek As New Infragistics.Web.UI.DataSourceControls.DataView()

 

' Set the required properties

viewOfDay.ID = "dsAgentWorkByDay_View"

viewOfDay.DataSourceID = Me.dsAgentWorkByDay.ID

 

viewOfWeek.ID = "dsAgentWorkByWeek_View"

viewOfWeek.DataSourceID = Me.dsAgentWorkByWeek.ID

 

' add Views to HierarchicalDataSource

hdsAgentWork.DataViews.Add(viewOfDay)

hdsAgentWork.DataViews.Add(viewOfWeek)

 

 ' create Relations

Dim dr As New Infragistics.Web.UI.DataSourceControls.DataRelation()

dr.ParentDataViewID = viewOfWeek.ID

dr.ParentColumns = New String() {"AW_AGENTID"}

dr.ChildDataViewID = viewOfDay.ID

dr.ChildColumns = New String() {"AW_AGENTID"}

Me.hdsAgentWork.DataRelations.Add(dr)

 

hdgAgentWork.DataKeyFields = "AW_AGENTID"

hdgAgentWork.DataSourceID = hdsAgentWork.ID

 

End Sub

 

It's wrong to do that in WebHierarchicalDataGrid_Init Funktion ?
