Hi Abhijeet Dhoke,
Thank you for contacting Infragistics.
From what I can see thus far, you're currently using the WebHierarchicalDataGrid's LoadOnDemand feature. That being said, here are some things to consider:1. The PrimaryKey should be set for each Table in your DataSource2. The DataKeyFields and DataMember properties should be set for each level in your WebHierarchicalDataGrid
To learn more about the LoadOnDemand feature, please review the following help topic:https://www.igniteui.com/help/infragistics.web.mvc~infragistics.web.mvc.igridmodel~loadondemand
Thanks for response.
I am trying to raise below RowExpanded event on parent row of webhierarchicaldatagrid:
Protected Sub ugSearchTrial_RowExpanded(sender As Object, e As Infragistics.Web.UI.GridControls.ContainerRowEventArgs) Handles ugSearchTrial.RowExpanded
'Dim val As string =ugSearchTrial.Rows(e.Row)End Sub
But this event is not firing when I click on any Parent row.
Also RowIslandsPopulating event not firing.
It will helpful for me if you attach/share any sample code to fire these events from webhierarchicaldatagrid.
Thanks,Abhijeet
