c#gridview rowupdating事件页面不呈现

标签: c# asp.net .net gridview

我遇到了问题。我的网页上有Gridview 编辑/更新/取消编辑。

页面工作/渲染,直到我将 OnRowUpdating =“UpdateRow”添加到Gridview。然后页面根本不呈现。
在调试中,它甚至没有进入页面加载事件。当我从Gridview中取出这个属性(而不触及代码背后的任何代码)时,页面呈现。我一直在谷歌搜索,找不到任何类似的东西。我可以发现它是不会触发/不起作用,但是没有关于页面不呈现的内容。

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"             
    >

如下所示更改功能的签名并检查。你是GridViewUpdatedEventArgs而不是GridViewUpdateEventArgs的绑定函数

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