上面是我的GridView代码，我还有大约8个其他列，但我删除了它们。

即使我有行编辑方法来捕获任何编辑，我的页面仍然会抛出错误：

您可以通过添加空事件来修复它

protected void grd_RowDeleting(object sender, GridViewDeleteEventArgs e)
{

}

从gridview代码中删除此

AutoGenerateEditButton="True"

这不是必需的。如果您在创建gridview时已经使用了自定义模板。我猜网格视图比您所做的更简单。

<asp:GridView ID="gvBuildList" runat="server" AutoGenerateColumns="False" AllowPaging="True" OnRowEditing="gvBuildList_RowEditing">
                                        <AlternatingRowStyle CssClass="alt"></AlternatingRowStyle>
                                        <Columns>
 <asp:BoundField DataField="ProductName" HeaderText="Product Name" SortExpression="ProductName" />
 <asp:BoundField DataField="Platform" HeaderText="Platform" SortExpression="Platform" />
 <asp:BoundField DataField="BuildDate" HeaderText="Build Date" SortExpression="BuildDate" />
 <asp:BoundField DataField="Publisher" HeaderText="Publisher" SortExpression="Publisher" />
 <asp:BoundField DataField="VersionNumber" HeaderText="Version #" SortExpression="VersionNumber" />
 <asp:BoundField DataField="FileName" HeaderText="Build" SortExpression="FileName" />
 <asp:BoundField DataField="ReleaseFileName" HeaderText="Release Notes" SortExpression="ReleaseFileName" />
 <asp:BoundField DataField="Comments" HeaderText="Comments" SortExpression="Comments" />

 <asp:ButtonField ButtonType="Image" CommandName="Edit" HeaderText="Edit"
                                                ImageUrl="Images/hard-drive-download.png" ShowHeader="True" Text="Edit" />

如果要在gridview中使用自定义模板，则必须使用“命令名称”属性。因为Gridview不会找到Edit事件。

用这个替换你的gridview，你的代码就可以了。

重建您的应用程序[编译您的代码]，您的错误将不复存在。

由于您已在Code中编写代码但未编译。所以gridview没有得到Row_editing事件。

转到 - ＆gt;构建 - ＆gt;重建解决方案

所以，在尝试了一些不同的东西后，最简单的解决方案。

我在pageload中有了gridview绑定。这就是造成这个问题的原因。我所要做的就是将GV绑定移动到

    if (!Page.IsPostBack)
    {
        getBuildData();
    }

在Page_Load方法

中

今天，我也遇到了这个问题。一小时后，我注意到Gridview事件选项卡中有两个事件。应注意事件名称：

  1. RowUpdating事件

  2. RowUpdate事件

    3. 确保您为代码使用正确的事件。

答案 5 :(得分：0)

GridView'GridView1'触发了未处理的事件RowEditing

只需将 CommandName =“ Edit” 更改为 CommandName =“ RowEdit”

答案 6 :(得分：-1)

只需更改＆＃34; CommandName＆＃34;编辑＆＃34;编辑＆＃34;或＆＃34;删除＆＃34;按钮来自＆＃34;编辑＆＃34; to＆＃34; Editttt＆＃34; ＆＃34;删除＆＃34;到＆＃34; Deleteee＆＃34; （或其他与你相关的东西，但要确保它不是＆＃34;编辑＆＃34;或＆＃34;删除＆＃34;）。它会正常工作。
