coolite TreeNode NodeClick传id到后台的方法

重点如下：

                <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"];
 5        if (string.IsNullOrEmpty(str) || str=="root")
 6        {
 7            BuildDataTable();
 8        }
 9        else
10        {
11            BuildDataTable(int.SafeParse(str));
12        }
13    }
