Asp.Net Treeview选择相同的节点不会触发

Question

我有一个asp.net树视图,它使用OnSelectedNodeChanged事件并且工作正常,但是如果你再次单击同一个节点它不会触发,任何想法如何绕过这个？

树视图:

<asp:TreeView ID="tvSOWASP" runat="server" ImageSet="Arrows" 
        ShowLines="True" OnTreeNodePopulate="PopulateNode" OnSelectedNodeChanged="SelectNode">
            <HoverNodeStyle Font-Underline="True" ForeColor="#5555DD" />
            <Nodes>
                <asp:TreeNode Expanded="True" ImageUrl="~/tree2/icons/book.gif" 
                    SelectAction="None" Text="Schemes Of Work" Value="Schemes Of Work">
                </asp:TreeNode>
            </Nodes>
            <NodeStyle Font-Names="Verdana" Font-Size="8pt" ForeColor="Black" 
                HorizontalPadding="5px" NodeSpacing="0px" VerticalPadding="0px" />
            <ParentNodeStyle Font-Bold="False" />
            <SelectedNodeStyle Font-Underline="True" ForeColor="#5555DD" 
                HorizontalPadding="0px" VerticalPadding="0px" />    
        </asp:TreeView>

代码隐藏:

protected void SelectNode(Object sender, EventArgs e)
{
    // Code here, ok when select any node, select same node and this code is not hit
}

嘿,请试试这个.

protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e){
// Do whatever you're doing
TreeView1.SelectedNode.Selected = false;
}

希望它能帮到你
