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
Hello Abhijeet,
If you are still experiencing this issue and are using .NET 4.0 then it is likely because you are somehow not setting up the grid properly. I am attaching a sample that demonstrates how to properly setup the grid. To go further with this matter you are going to have to send an isolated sample that reproduces the issue you are seeing.
Thanks mike, Please have look into it, I think its challenging query for INFRAGISTIC development team.
