Answer 1

在模板行的ID您网格视图，将按钮的CommandArgument属性绑定到行的ID。然后在按钮单击事件上，从事件参数中检查commandArgument属性。这会给你的ID

要伴随着@ Midhat的答案去，这里是一些示例代码：

代码隐藏：

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(); 
    } 
    } 
} 

的标记：

<form id="form1" runat="server"> 
<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> 


</form>
