重點(diǎn)如下：

1????????????????<AjaxEvents>
2????????????????????<Click?OnEvent="PanelTree_Click"?>
3????????????????????????<EventMask?ShowMask="true"?Msg="正在執(zhí)行,請(qǐng)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>
這邊value="node.id"就可以餓了，模式一定要改為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));
