Above is my GridView code, I have about 8 other columns too but I removed them.

以上是我的 GridView 代码，我还有大约 8 个其他列，但我删除了它们。

Even though I have the row Editing method to catch any edits, my page keeps on throwing the error:

即使我有行编辑方法来捕捉任何编辑，我的页面仍然抛出错误：

The GridView 'gvBuildList' fired event RowEditing which wasn't handled.

GridView 'gvBuildList' 触发了未处理的事件 RowEditing。

I had my gridview binding in pageload. That was what was causing this issue. All I had to do was move the GV binding to

我在页面加载中有我的 gridview 绑定。这就是导致这个问题的原因。我所要做的就是将 GV 绑定移动到

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

Within the Page_Load Method

在 Page_Load 方法中

ReBuild you application [Compile your code] and your error will be no more.

重新构建您的应用程序 [编译您的代码]，您的错误将不再存在。

As you have written code in Code behind but not compiled. so gridview is not getting the Row_editing event.

由于您在 Code 后面编写了代码但未编译。所以 gridview 没有得到 Row_editing 事件。

From your gridview Code remove this

从你的 gridview 代码中删除这个

AutoGenerateEditButton="True"

This is not required.as you have taken the Custom Template in creating your gridview.I guess the gridview is more simple than what you have done.

这不是必需的。因为您在创建 gridview 时使用了自定义模板。我猜 gridview 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" />

If you want to use Custom Template in gridview then you have to Use Command Name property. as Gridview will not find the Edit event.

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 将找不到 Edit 事件。

Replace your gridview with this one and your code will work.

用这个替换你的 gridview，你的代码就会工作。

You can fix it by adding an empty event

您可以通过添加一个空事件来修复它

protected void grd_RowDeleting(object sender, GridViewDeleteEventArgs e)
{

}

Today, I also faced this problem. After one hour, I noticed that there are two events in Gridview events tab. Events names should be noted:

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 Event

2. RowUpdate Event

1. 行更新事件

2. 行更新事件

Make sure you are using right event for your code.

确保为代码使用正确的事件。

Just change the "CommandName" property of the "Edit" or "Delete" button from "Edit" to "Editttt" "Delete" to "Deleteee" (or something else which is relevent to you but make sure it is not "Edit" or "Delete"). It will works fine.

只需将“编辑”或“删除”按钮的“CommandName”属性从“编辑”更改为“Editttt”“删除”到“Deleteee”（或其他与您相关的内容，但请确保它不是“编辑”或“删除”）。它会正常工作。
