coolite TreeNode NodeClick传id到后台的方法

重点如下：

1                  < AjaxEvents >
2                      < Click  OnEvent ="PanelTree_Click"   >
3                          < EventMask  ShowMask ="true"  Msg ="正在执行,请稍后"   />
4                          < ExtraParams >
5                             < ext:Parameter  Name ="Id"  Value ="node.id"  Mode ="Raw" ></ ext:Parameter >  
6                          </ ExtraParams >
7                      </ Click >
8                     
9                  </ AjaxEvents >

  <ext:Parameter Name="Id" Value="node.id" Mode="Raw"></ext:Parameter>
这边value="node.id"就可以饿了，模式一定要改为Raw

 

code Behind

 1     [AjaxMethod]
 2      protected   void  PanelTree_Click( object  sender,AjaxEventArgs e)
 3      {   
 4        string str = e.ExtraParams["Id"];
