Just to help viewers to provide solution - I am adding few lines from .aspx & .cs, when we select Treenode 'Machine' - it gets selected but 'Assembly1' does not.

TreeView.aspx

<asp:TreeView ID="TreeView1" runat="server" ShowLines="true"

CssSelectorClass="PrettyTree" OnSelectedNodeChanged="OnTreeSelection" OnAdaptedSelectedNodeChanged="OnTreeSelection">

<Nodes>

<asp:TreeNode Text="Machine"

Value="Machine1" ImageUrl="~/Images/Assembly.bmp" Expanded="false">

<asp:TreeNode Text="Assembly 1" Value="Assembly1" ImageUrl="~/Images/Assembly.bmp" NavigateUrl="~/imgPlaceHolder.aspx" Target="RightFrame">

<asp:TreeNode Text="Component A1" Value="ComponentA1" ImageUrl="~/Images/Component.bmp">

</asp:TreeNode>

</asp:TreeNode>

<asp:TreeNode Text="Component 1" Value="Component" ImageUrl="~/Images/Component.bmp">

</asp:TreeNode>

</asp:TreeNode>

</Nodes>

<SelectedNodeStyle CssClass="AspNet-TreeView-Selected" />

</asp:TreeView>

 

TreeViewAdapter.cs

public void RaisePostBackEvent(string eventArgument)

{

...

if (selectedNode != null)

{

bool bSelectedNodeChanged = selectedNode != treeView.SelectedNode;

ClearSelectedNode(items);

selectedNode.Selected = true;

...

}

}
