                    <ItemTemplate>
                    <asp:LinkButton ID="sendrequest" runat="server" Text="SendRequest" CommandName="SendRequest"></asp:LinkButton>
                    </ItemTemplate>
                    </asp:TemplateField>

                    <asp:TemplateField HeaderText="FirstName">

我的问题是需要其中的LinkBut​​ton（sendRequest将）点击该行的电子邮件值的电子邮件值

推荐答案

处理GridView的RowCommand事件：

Handle the GridView RowCommand event:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName.Equals("SendRequest")) 
    { 
       string strEmail = GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Value.ToString();
       lbltest.Text = strEmail; 
    } 
} 

这是假设你有设置的电子邮件的的的DataKeyNames。
您还必须设置的CommandArgument中的 sendRequest将的按钮

that is assuming you have the DataKeyNames set as email. You must also set the CommandArgument of the sendRequest button to

CommandArgument="<%# Container.DataItemIndex %>
