c#gridview onRowUpdate事件页不呈现

我有个问题。我有一个页面有一个

Gridview

，上面有编辑/更新/取消编辑

该页面一直工作/呈现，直到我将onrowUpdatement=“UpdateRow”添加到

Gridview

。然后该页面根本不呈现。
在调试过程中，它甚至不会进入页面加载事件。当我将此属性从Gridview中取出时（不接触任何代码隐藏代码），页面将呈现。我一直在谷歌上搜索，找不到类似的东西。我可以找到它是否不启动/不工作，但与页面未呈现无关

我的代码如下：

    <asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None"
        AutoGenerateColumns="false" 
        Width="100%" 
        OnRowEditing="EditRow" 
        OnRowUpdating="UpdateRow"
        OnRowCancelingEdit="CancelEditRow" 
        DataKeyNames="OnCallID"             
        AllowPaging="true"
        PageSize="50" 
        OnPageIndexChanging="ChangePage"            
        OnRowDataBound="gvVehicle_OnRowDataBound"

如下更改函数的签名并检查。您正在使用GridViewUpdateEventArgs而不是GridViewUpdateEventArgs绑定函数

protected void UpdateRow(object sender, GridViewUpdateEventArgs e)
{
}

这似乎奏效了。我犯了愚蠢的错误。不确定这为什么会导致页面根本不呈现（调试时甚至无法加载页面）？？仍在测试中，但至少页面现在正在呈现，当我单击“更新”时，我将进入该函数。谢谢
