Question

我有一个gridview，我有两个按钮编辑和删除。一旦我点击编辑按钮，我取值并将其放在网格外的文本框中，可见更新和取消按钮。但这并没有激发..

<asp:UpdatePanel ID="UpdatePanel2" runat="server">
          <ContentTemplate>
                <asp:Panel ID="pnladdproduct" runat="server">

          </Triggers>
</asp:UpdatePanel>

服务器端代码..

 protected void grdProduct_RowEditing(object sender, GridViewEditEventArgs e)
    {

        Session["proID"] = StepGetHiddenValuesFromGridControl(e.NewEditIndex);
        txtQuantity.Text = grdProduct.Rows[e.NewEditIndex].Cells[1].Text;
        txtRate.Text = grdProduct.Rows[e.NewEditIndex].Cells[2].Text;
        txtAmount.Text = grdProduct.Rows[e.NewEditIndex].Cells[3].Text;
        txtQuantity.BackColor = Color.Beige;
        txtRate.BackColor = Color.Beige;
        txtAmount.BackColor = Color.Beige;
        //pnladdproduct.Visible = false;
        //pnlUpdateProduct.Visible = true;
        //pnlCancel.Visible = true;
   }

protected void btnUpdateProduct_Click(object sender, EventArgs e)
    {
        // this code not firing
    }

我认为不需要触发器。

一旦点击gridview的编辑按钮，Gridview按钮就不会触发
