TreeView展开无闪烁的解决方法(VB版，只是将江雨的代码翻成VB的) '实现TreeView展开不提交，点击才提交
            '------------------------------------------------------
            Dim strTreeName As String = "TreeView1"
            Dim strRef As String = Page.GetPostBackEventReference(TreeView1)            Dim strScript As String = "<script language='JavaScript'> " & vbCrLf _
            & "<!-- " & vbCrLf _
            & " function initTree() { " & vbCrLf _
            & " " & strTreeName & ".onSelectedIndexChange = function() { " & vbCrLf _
            & " if (event.oldTreeNodeIndex != event.newTreeNodeIndex) " & vbCrLf _
            & " this.queueEvent('onselectedindexchange', event.oldTreeNodeIndex + ',' + event.newTreeNodeIndex); " & vbCrLf _
            & " window.setTimeout('" & strRef.Replace("'", "\'") & "', 0, 'JavaScript'); " & vbCrLf _
            & " } " & vbCrLf _
            & " } " & vbCrLf _
            & "// --> " & vbCrLf _
            & "</script>"
            Page.RegisterClientScriptBlock("InitTree", strScript)
            '-------------------------------------------------------
*************.Cs 中的代码**************************** string  strScript="<script  language=\"javascript\" >";
strScript+=" function GetNode() \n"+"{ \n";
strScript+=" alert(TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute('Text'));\n" ;
strScript+=" alert(TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute('CheckBox'));\n";
strScript+=" alert(TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute('Checked'));\n";
strScript+=" if (TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute('Checked'))\n";
strScript+="     TreeView1.getTreeNode(TreeView1.clickedNodeIndex).setAttribute('Checked','false');\n";
strScript+="  else \n";
strScript+="     TreeView1.getTreeNode(TreeView1.clickedNodeIndex).setAttribute('Checked','true');\n";
    strScript+=" \n } \n";
strScript+="</script>";
if(! this.IsClientScriptBlockRegistered("myjs"))
{
this.RegisterClientScriptBlock("myjs",strScript); 
}

好象treevalue每次和后台程序连接的时候都会闪烁,不过好象说用iframe可以搞定这样的问题
