Question

我想在包含按钮控件的gridview中添加一列。我使用ID（整数和主键）作为Gridview的第一列。我想要的是当用户点击gridview的任何给定行上的按钮时，我希望能够确定所单击按钮所属的行的ID

Answer 1

在网格视图的模板中，将按钮的CommandArgument属性绑定到行的ID。然后在按钮单击事件上，检查事件args中的commandArgument属性。这将为您提供ID

与@ Midhat的回答一起，这里有一些示例代码：

public partial class _Default : System.Web.UI.Page
{
  List<object> TestBindingList;

  protected void Page_Load(object sender, EventArgs e)
  {
    if (!IsPostBack)
    {
        TestBindingList = new List<object>();
        TestBindingList.Add(new { id = 1, name = "Test Name 1" });
        TestBindingList.Add(new { id = 2, name = "Test Name 2" });
        TestBindingList.Add(new { id = 3, name = "Test Name 3" });

        this.GridView1.DataSource = TestBindingList;
        this.GridView1.DataBind();
    }

  }

  protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
  {         
    if (e.CommandName == "Select")
    {
        int index = Convert.ToInt32(e.CommandArgument);
        this.Label1.Text = this.GridView1.DataKeys[index]["id"].ToString();
    }
  }
}

<asp:GridView ID="GridView1" runat="server"  
    onrowcommand="GridView1_RowCommand" DataKeyNames="id">
    <Columns>
        <asp:TemplateField HeaderText="ButtonColumn">
            <ItemTemplate>
                <asp:Button ID="Button1" runat="server" CausesValidation="false" 
                    CommandName="Select" Text="ClickForID"
                     CommandArgument="<%# ((GridViewRow)Container).RowIndex %>" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>
<asp:Label ID="Label1" runat="server" Text="ID"></asp:Label>
