Question

我在一个页面中设置了两个Gridview。一个人选择的索引改变了事件加载另一个事件。但是，第二个网格的selectedindexchanged事件继续进行首次选择的索引更改事件。我能做什么？我的功能名称是正确的。没有任何其他冲突。

这是我的asp代码：

<asp:GridView ID="gdv" runat="server" 
                AutoGenerateColumns="False" onrowdatabound="gdv_RowDataBound" 
                onselectedindexchanged="gdv_SelectedIndexChanged" AllowPaging="True" 
                Width="100%" onpageindexchanging="gdv_PageIndexChanging">
                <Columns>
                    <asp:BoundField DataField="Sl" HeaderStyle-HorizontalAlign="Center"

                    <HeaderStyle HorizontalAlign="Center" />
                    <ItemStyle HorizontalAlign="Center" />

                    <asp:BoundField DataField="SalesOrderNo" HeaderStyle-HorizontalAlign="Left"

}

Answer 1

测试足以知道事件的起源。例如：

        private void dataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if(dataGrid1.SelectedItem!=null)
                MessageBox.Show("aaaaaaaaaaa");
        }

        private void dataGrid2_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if (dataGrid2.SelectedItem != null)
                MessageBox.Show("BBBBBbbBBBB    ");
        }

Answer 2

只需打开gridviews的事件窗口，然后选择其中一个，然后在事件窗口中双击“selected index changed”事件。它会将你带到代码部分。如果您处于真实过程中，则事件绑定为真。如果不是，你必须改变你的程序的定义。

这是一个简单的过程。

复制程序中的代码并将其粘贴到安全的地方。
删除与gridviews相关的程序
检查网格视图的事件页面，以确保“选定的索引已更改”事件中没有任何内容。
双击第一个gridviews“selected index changed”事件。它会创建一个空白程序。在此处粘贴相关代码。
做第二次。

另一件事是在属性窗口中检查gridviews的验证组。它们应该是不同的：）

不：请原谅我不能直接编写代码。因为我不在自己的电脑上我希望它有效。

两个gridview selectedindexchanged事件不起作用
