我做了个树型目录,想要获取选中的节点的名称.但我定义的TreeView_SelectedIndexChange()事件并没有被执行.求高手指教.代码如下:
private void TreeView_SelectedIndexChange(object sender, Microsoft.Web.UI.WebControls.TreeViewSelectEventArgs e)
{
text.Value=TreeView.GetNodeFromIndex(TreeView.SelectedNodeIndex).Text; },其中AutoPostBack属性社为False,如社为ture的话TreeView_SelectedIndexChange()就可以执行，我试过了的，但是刷新得让我感到痛苦，有没有什么方法 ，在AutoPostBack属性社为False的时候，也会执行TreeView_SelectedIndexChange()事件？
private void TreeView_SelectedIndexChange(object sender, Microsoft.Web.UI.WebControls.TreeViewSelectEventArgs e)
{
text.Value=TreeView.GetNodeFromIndex(TreeView.SelectedNodeIndex).Text; },其中AutoPostBack属性社为False,如社为ture的话TreeView_SelectedIndexChange()就可以执行，我试过了的，但是刷新得让我感到痛苦，有没有什么方法 ，在AutoPostBack属性社为False的时候，也会执行TreeView_SelectedIndexChange()事件？
private void Page_Load(object sender, System.EventArgs e)
{
// Reset Error
this.lblError.Text = string.Empty; if (!this.IsPostBack)
{
try
{
SetPageItem(); string strTreeViewImageUrl = System.Configuration.ConfigurationSettings.AppSettings["TreeViewImageUrl"];
tvDocDir.Dispose();
tvDocDir.SystemImagesPath = strTreeViewImageUrl + "treeimages/";
tvDocDir.ImageUrl = strTreeViewImageUrl + "images/folder.gif";
tvDocDir.ExpandedImageUrl = strTreeViewImageUrl + "images/folder.gif";
tvDocDir.SelectedImageUrl = strTreeViewImageUrl + "images/folderopen.gif"; this.rebuildTree("0"); tvDocDir_SelectedIndexChange( new object() , new Microsoft.Web.UI.WebControls.TreeViewSelectEventArgs("0","0"));
}
catch( Exception ex )
{
this.Response.Redirect("Error.aspx?errorMsg="+Server.UrlEncode(ex.Message));
}
} // Set Tree Not PostBack
string strTreeName = "tvDocDir";
string strRef = Page.GetPostBackEventReference(tvDocDir);
string strScript = "<script language=\"JavaScript\"> \n" + "<!-- \n" + " function initTree() { \n" +" " + strTreeName + ".onSelectedIndexChange = function() { \n" + "if (event.oldTreeNodeIndex != event.newTreeNodeIndex) \n" + "this.queueEvent('onselectedindexchange', event.oldTreeNodeIndex + ',' + event.newTreeNodeIndex); \n" + "window.setTimeout('" + strRef.Replace("'","\\'") + "', 0, 'JavaScript'); \n" + " } \n" + " } \n" + "// --> \n" + "</script>";
Page.RegisterClientScriptBlock("InitTree",strScript );
}
