c# - 如何通过单击 ASP.NET gridview 中一行中的按钮获取行数据

Question

我在 ASP.NET web 应用程序中有一个 GridView，我在其中的每一行中添加了两个按钮:

 <ItemTemplate>
    <asp:Button ID="btnEdit" Text="Edit" runat="server" />
    <asp:Button ID="btnDelete" Text="Delete" runat="server"/>
 </ItemTemplate>

现在如何通过单击一行中的编辑按钮从 gridview 中获取行数据？

Answer 1

你也可以像这样使用按钮点击事件:

<asp:TemplateField>
    <ItemTemplate>
        <asp:Button ID="Button1" runat="server" Text="Button" 
                    OnClick="MyButtonClick" />
    </ItemTemplate>
</asp:TemplateField>

protected void MyButtonClick(object sender, System.EventArgs e)
{
    //Get the button that raised the event
    Button btn = (Button)sender;

    //Get the row that contains this button
    GridViewRow gvr = (GridViewRow)btn.NamingContainer;
} 

或

你可以这样获取数据:

 void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
 {

    // If multiple ButtonField column fields are used, use the
    // CommandName property to determine which button was clicked.
    if(e.CommandName=="Select")
    {
      // Convert the row index stored in the CommandArgument
      // property to an Integer.
      int index = Convert.ToInt32(e.CommandArgument);    

      // Get the last name of the selected author from the appropriate
      // cell in the GridView control.
      GridViewRow selectedRow = CustomersGridView.Rows[index];
    }
}

gridview 中的 Button 应该有这样的命令并处理 rowcommand 事件:

<asp:gridview id="CustomersGridView" 
        datasourceid="CustomersSqlDataSource" 
        autogeneratecolumns="false"
        onrowcommand="CustomersGridView_RowCommand"
        runat="server">

        <columns>
          <asp:buttonfield buttontype="Button" 
            commandname="Select"
            headertext="Select Customer" 
            text="Select"/>
        </columns>
  </asp:gridview>
