Hi,

I have a treeview on a page, when I select a node it displays the selected node's name on a label and highlights the selected node in red - This works... but does a terrible refresh of the page before excecuting this......

Ive used and update panel(AJAX), but when it "refreshes" the treeview, it :

1. Doesnt Highlight the selected node in red

2. Duplicates the "FIRST" selected nodes text everytime a node is selected......

 Does anyone know of a way to stop this from happening???

Thank you for any assistance....

Perhaps this will help a bit : This is my code below

Dim objConn As String = ConfigurationManager.AppSettings("Fleetcube.ConnectionString")

Dim objCommand As New SqlCommand("select id,name,(select count(*) FROM org_Branch " _

End Sub

'Nodes

ByVal nodes As TreeNodeCollection)

Dim tn As New TreeNode()

'If node has child nodes, then enable on-demand populating

Next

End Sub

'Sub levels

Dim objConn As String = ConfigurationManager.AppSettings("Fleetcube.ConnectionString")

Dim objCommand As New SqlCommand("select id,name,(select count(*) FROM org_Branch " _

myConnection) '//////////////////////

End Sub

If Not Page.IsPostBack Then

End If

end sub

Hi,

In fact,  the ASP.Net Menu and the Treeview control are not compatible with with partial-page updates, and are therefore not supported inside an UpdatePanel control.  You can refer the part of Controls that Are Not Compatible with UpdatePanel Controls of this link: http://www.asp.net/ajax/documentation/live/overview/UpdatePanelOverview.aspx

If  you want to highlight the selected node in red, you can set the treeview's SelectedNodeStyle's forecolor is red,  for example: <SelectedNodeStyle ForeColor="Red" />

Hope it helps.

Hey - Thanks Amanda Wang!

I see that if the tree view is in the update panel, it even gives errors on the page..... thanks for refering me to the page to see which controls are not compatible with the update panel..... I will be using a differant approach.

Thanks
