asp.net - 当我从后面的代码将按钮添加到 GridView 的单元格时，单击事件不会调用

Question

我使用下面的代码从代码后面将按钮添加到 GridView 的单元格，但是当我单击我添加的每个按钮时，单击事件 (lnk_Click) 不会调用，并且在我单击它后按钮会隐藏。我怎么能解决这个问题？

//aspx
    <asp:GridView ID="GridView1" runat="server" GridLines="None" Width="940px"
      OnSelectedIndexChanged="grid_SelectedIndexChanged"
      onrowdatabound="GridView1_RowDataBound" AutoGenerateColumns="False" CssClass="gridview">
       <Columns>
          <asp:TemplateField HeaderText="...">
               <ItemTemplate>
                   <asp:Panel ID="pnlSteps" runat="server"></asp:Panel>
               </ItemTemplate>
          </asp:TemplateField>
       </Columns>
  </asp:GridView>

    //Code behind
    for (int i = 0; i < GridView1.Rows.Count; i++)
            {
                Panel pnl = (Panel)GridView1.Rows[i].Cells[0].FindControl("pnlSteps");
                LinkButton lnk = new LinkButton();
                lnk.Text = "...";
                pnl.Controls.Add(lnk);
                lnk.Click += new EventHandler(lnk_Click);
            }//for
    ...

    protected void lnk_Click(object sender, EventArgs e)
        {
    //...
    }

//编辑

我用下面的代码填充gridview

//dsSet is DataSet that i fill it with data from Database
DataTable dtt = new DataTable();

        dtt.Columns.Add(new DataColumn("status", typeof(string)));
        dtt.Columns.Add(new DataColumn("finantial", typeof(string)));
        dtt.Columns.Add(new DataColumn("phone", typeof(string)));
        dtt.Columns.Add(new DataColumn("name", typeof(string)));
        dtt.Columns.Add(new DataColumn("code", typeof(string)));

        for (int i = 0; i < dsSet.Tables[0].Rows.Count; i++)
        {
            DataRow dr = dtt.NewRow();

            dr[0]=...;
            dr[1]=...;
            dr[2]=...;
            dr[3]=...;
            dr[4]=...;

            dtt.Rows.Add(dr);
        }//for
        GridView1.DataSource = dtt;
        GridView1.DataBind();

因为按钮在 gridview 中，所以你不能在 onclick 中获取它的点击事件，但你必须使用 GridView.RowCommand并在按钮中使用 commandname

编辑

<asp:TemplateField>
  <ItemTemplate>
    <asp:Button ID="AddButton" runat="server" 
      CommandName="commandName" 

      Text="command" />
  </ItemTemplate> 
</asp:TemplateField>

代码隐藏:

protected void GridView1_RowCommand(object sender, 
  GridViewCommandEventArgs e)
{
  if (e.CommandName == "commandName")
  {
     // add your code
  }

}
