{
  if (DdlCity.SelectedIndex == 0)
        {
            cityid = branchid = deptid = 0;
        }
        else
        {
            cityid=Convert.ToInt64(DdlCity.SelectedValue.ToString());
            branchid=Convert.ToInt64(DdlBranch.SelectedValue.ToString());
            if (branchid == 0)
            {
                deptid = 0;
            }
            else
            {
                deptid = Convert.ToInt64(DdlDepartment.SelectedValue.ToString());

            }

        }
        
       
        countryid = Convert.ToInt64(Ddlcountry.SelectedValue.ToString());
        if (countryid != 0 && cityid != 0 && branchid != 0 && deptid != 0)
        {
            dsinfo = bl.BsearchEmp(countryid, cityid, branchid, deptid);
        }
        else if (countryid != 0 && cityid != 0 && branchid != 0)
        {
            dsinfo = bl.searchEmployee(countryid, cityid, branchid);
        }
        else if (countryid != 0 && cityid != 0 )
        {
            dsinfo = bl.searchEmployee(countryid, cityid);
        }
        else
        {
            dsinfo = bl.searchEmployee(countryid);
        }


        
       
        Session["mydataset"] = dsinfo;
        GridView1.DataSource = (DataSet)Session["mydataset"];
        GridView1.DataBind();
        BtnDumpToExcel.Visible = true;
        BtnPrint.Visible = true;
}
  protected void Get_Employee_Id_from_grid(object sender, EventArgs e)
    {
        Button btn= sender as Button;
        if (btn != null)
        {
            string Employee_Id = btn.CommandArgument;
            
            Session["Gridview_Employee_id"] = Employee_Id;

            Response.Redirect("ViewEmployeeDetail.aspx");
        }

从ViewEmployeeDetail.aspx返回后，我想查看之前加载的相同网格.
我的网格位于更新面板中，我按了我的按钮以触发该网格.

请咨询..

after coming back from ViewEmployeeDetail.aspx i want to see the same grid which is loaded before.
and my grid is in update panel ang i made my button as a trigger to that grid.

please advice..

推荐答案

在pageLoad事件上绑定gridview，检查会话并绑定网格.

如果我没看错，则必须在Page_Load事件中编写这些代码

Bind the gridview on pageLoad event , check for the session and bind the grid.

If I am not wrong , you have to write these codes on Page_Load event

GridView1.DataSource = (DataSet)Session["mydataset"]; 
GridView1.DataBind();
