c# - 如何更新或刷新选项卡容器中的面板或控件

Question

我正在处理一个选项卡式页面(4 个选项卡 - 选项卡容器)，其中 2 个使用相同的控件并且具有不同的 gridview 和不同的数据源，可以编辑和添加项目。

编辑和添加项目工作正常，但是当我添加项目时，gridview 或页面需要刷新或更新以显示新项目。使用 Response.Redirect 只会刷新页面并重定向到第一个选项卡。我正在处理选项卡 2 和 3，重定向需要指向相关选项卡，而不是总是指向第一个选项卡。

关于如何做到这一点有什么建议吗？

我正在使用 Visual Studio 2010、C# ASP.Net

Answer 1

毕竟，我所需要的只是 databind();像这样....

protected void btnAdd_Click(object sender, EventArgs e)
    {

        this.divAddEditRow.Visible = false;
        btnShowAddSection.Visible = true;

        if (pnlStatus.Visible == true)
        {               
            WorkflowDataService.InsertWFStatus(0, txtEdit.Text);
            gvStatus.DataBind();
        }

        if (pnlAction.Visible == true)
        {
            WorkflowDataService.InsertWFAction( 0, txtEdit.Text);
            gvAction.DataBind();
        }   
    }
