需要使用__doPostBack调用服务器端事件 [英] Need to call server side event using __doPostBack

问题描述

我有这样的服务器端事件.

I have server side event like this.

protected void RadTreeView1_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)
    {
         // implementation here.
    }

我正在尝试从客户端javascript调用它.我已经尝试过__doPostBack("contextMenuItemID"，某些字符串")

I am trying to call it from client side javascript. I have tried __doPostBack("contextMenuItemID", "some string")

它将页面重新发布到服务器，但这不会调用原始的ContextMenuItemClick事件.如何使用适当的事件Args调用原始的contextMenuItemClick事件?

it posts the page back to server, but this does not invoke the original ContextMenuItemClick event. How can I invoke the original contextMenuItemClick event with proper event Args?

推荐答案

您将要使用

You'll want to look at using the ClientScriptManager.GetPostBackEventReference method. This will create the correct javascript call ("__doPostBack") for the control/action using the ClientScriptManager (untested example):

<script type="text/javascript">
    function callPostBack() {
        <%= Page.ClientScript.GetPostBackEventReference(RadTreeView1, String.Empty) %>;
    }
</script>
