preserve expand detailtables after rebind vb.net

[Phillip]

Is there an newer/easier way to preserve the expand state of detailtables after rebind?

I've seen the below example, but I need an example in vb.net and the conversion does not work.

Hello Phillip,

I have converted the code from the code library to VB.
You can find it attached to this message.

I hope it helps.

Thanks.  Should this work with an ajax refresh?  Here is the refresh that I'm using.  It does not appear to be working, yet. 

 

 

<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1"

 

 

 

DisplayAfter="0">

 

 

 

</asp:UpdateProgress>

 

　

 

 

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

 

 

 

<ContentTemplate>

 

 

 

<asp:Timer ID="Timer1" runat="server" Interval="3000" OnTick="Timer1_Tick">

 

 

 

</asp:Timer>

 

 

 

Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs)

 

RadGrid1.Rebind()

 

 

End Sub

Hello Phillip,

I have modified the project from my previous post to implement the desired functionality with the timer. You can find the updated version attached to this post.

I hope it helps.

The demo is working for me, but not when I try to duplicate in my project.  Each time the grid is rebound by timer1 it closes the expanded details tables.  I am using SQLDataSource's.. could this be a problem?  Thanks

Hello Phillip,

I have retested my project and it is working fine on my side.

Please let me know if there are any differences at your end, which I may be leaving out.

Best wishes,
