treeview的autoPostBack。

function postBackByObject()
{
    var o = window.event.srcElement;
    if (o.tagName == "INPUT" && o.type == "checkbox")
    {
       __doPostBack("","");
    }
}

 

<asp:TreeView ID="TreeView1"  EnableClientScript="true" runat="server" ShowCheckBoxes="All" OnTreeNodeCheckChanged="TreeView1_TreeNodeCheckChanged" onclick="javascript:postBackByObject(event);">
                        </asp:TreeView>

 

给treeview的click事件加上这个js方法，treeview实现autoPostBack的效果了。
