Question

我已动态创建数据表绑定到网格视图。在每一行中，我都添加了我在网格视图中定义的按钮。现在我希望该按钮调用另一个按钮单击事件并对值进行修改。这可能吗？这是我的代码：

 <asp:GridView ID="GridView2"  runat="server" OnRowDataBound="GridView2_RowDataBound">
        <Columns>
    <asp:TemplateField>
    <ItemTemplate>
    <asp:Button ID="btnTest" runat="server" CommandName="odzemi" CssClass="button2" OnClick="btnTest_Click" Text="-" Width="100px" Font-Bold="True" />
        <asp:Button ID="Button15" Visible="false" runat="server" Text="Button" />
         </ItemTemplate>
    </asp:TemplateField>


            </Columns>
                   </asp:GridView>


   protected void btnTest_Click(object sender, EventArgs e)
    {
        Session["Counter1"] = newValue;
        Session["Counter"] = newValue;
        if (Session["Markici"] != null || Session["Markici"] != null)
        {

            var clickedRow = ((Button)sender).NamingContainer as GridViewRow;
            var clickedIndex = clickedRow.RowIndex;

            /*decimal*/ old = dtCurrentTable.Rows[clickedIndex].Field<decimal>("Kolicina");

            decimal oldIznos = dtCurrentTable.Rows[clickedIndex].Field<decimal>("VkIznos");
            decimal VkDanok = dtCurrentTable.Rows[clickedIndex].Field<decimal>("VkDanok");
            string Cena1 = dtCurrentTable.Rows[clickedIndex].Field<string>("Cena1");
            int TarifaID = dtCurrentTable.Rows[clickedIndex].Field<Int16>("TarifaID");

           // decimal pocentDanok0 = 0.0m;
          //  decimal pocentDanok1 = 0.18m;              
          //  decimal pocentDanok2 = 0.5m;



            //int oldValue = int.Parse(old); 
           /* decimal*/ newValue = old - 1; //
           Label37.Text = newValue.ToString();

            decimal newIznos = oldIznos - Convert.ToDecimal(Cena1);

            dtCurrentTable.Rows[clickedIndex].SetField("Kolicina", newValue.ToString());      
            dtCurrentTable.Rows[clickedIndex].SetField("VkIznos", newIznos.ToString());

} //我想在这里打电话给btn_test点击并调整他的价值

  protected void Button7_Click(object sender, EventArgs e)
    {

        if (GridView2.Rows.Count == 0)
        {
            Response.Redirect("MasiGradskaKafanak1.aspx");
        }
        SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["string2"].ConnectionString);




       Session["Counter"] = counter;
        Label11.Text =  counter.ToString();

      //  Label11.Text = Session["kolicina2"].ToString(); //ViewState["count"].ToString(); //

您可以使用EditItemTemplate来对应gridview中的每个模板字段。

确定按钮单击并修改另一个按钮aspx.net中的值
