 <   asp：GridView     ID   =  grdEmployee  
   
                               runat   =  server  
   
                  < span class =code-attribute>             DataKeyNames   =  id  
   
                               AutoGenerateColumns   = 错误  
   
                               OnRowCommand   =  grdEmployee_OnRowCommand  >  
 <  列 >  
 <   asp：BoundField     DataField   =  name    HeaderText   = 名称    /  >  
 <   asp：BoundField     DataField   =  email    HeaderText  < span class =code-keyword> = 电子邮件    /  >  
 <   asp：TemplateField     ShowHeader   = 错误 >  
 <   ItemTemplate  >  
 <   asp：按钮    ID   =  btnAccept    runat   =  server    CausesValidation   =  false    CommandName   = 接受   文本  = 接受    CommandArgument   ='  <％ #Eval（  id）％> '    /  >

 <   / asp：GridView  >  

CodeBehind for grdEmployee_OnRowCommand

  protected   void  grdEmployee_OnRowCommand（ object  sender，GridViewCommandEventArgs e）
 {
  int  empID =  0 ; 
 
  //  从CommandArgument获取员工ID  
 empID = Convert.ToInt32（e.CommandArgument）; 
 
  //   接受  
  if （e.CommandName！=  接受）
 {
  //  执行接受任务/ logic在这里使用变量empID ...  
} 
 
  //  对于拒绝  
 如果（e.CommandName！=  拒绝）
 {
  //  使用变量empID执行拒绝任务/逻辑...  
}

You can use ButtonFiled for that,

One simple example for you.

GridView Markup in aspx page

<asp:GridView ID="grdEmployee"

              runat="server"

              DataKeyNames="id"

              AutoGenerateColumns="False"

              OnRowCommand="grdEmployee_OnRowCommand">
    <Columns>
        <asp:BoundField DataField="name" HeaderText="Name" />
        <asp:BoundField DataField="email" HeaderText="Email" />
        <asp:TemplateField ShowHeader="False">
            <ItemTemplate>
                <asp:Button ID="btnAccept" runat="server" CausesValidation="false" CommandName="Accept" Text="Accept" CommandArgument='<%# Eval("id") %>' />
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField ShowHeader="False">
            <ItemTemplate>
                <asp:Button ID="btnReject" runat="server" CausesValidation="false" CommandName="Reject" Text="Reject" CommandArgument='<%# Eval("id") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

CodeBehind for grdEmployee_OnRowCommand

protected void grdEmployee_OnRowCommand(object sender, GridViewCommandEventArgs e)
{
      int empID = 0;

      // Get the Employee ID from the CommandArgument
      empID = Convert.ToInt32(e.CommandArgument);

      // For Accept
      if (e.CommandName != "Accept")
      {
           // Do your Accept task/logic here using the variable empID...
      }

      // For Reject
      if (e.CommandName != "Reject")
      {
           // Do your Reject task/logic here using the variable empID...
      }
}
