    I'm trying to get an aspx datagrid control to perform a post that results in a partial postback (asynchronous) rather than a full postback. I've added scriptmanager, an update panel, and a content template wrapper and yet it still refreshes the page when i select a data item and click add.

    解决方案

    also try this :

    Control me = FindControl(Request.Params.Get("__EVENTTARGET"));
if(FindControl(me!=addButton && me!=removeButton && me!=addAllButton && me!=removeAllButton)
 {
    if (IsPostBack)
        return;
    if (String.IsNullOrEmpty(Request["id"]))
    {
        Response.Redirect("default.aspx");
    }
    else
    {
        LoadData();
    }
 }
