Question

我想根据ddlCat和ddlSubCat（下拉列表）的选择，将“Manage-Cat-Subcat.aspx”从“Mainpage.aspx”重定向到显示panel1和panel2 ......

重定向到“Manage-Cat-Subcat.aspx”页面以显示 Panel1：

protected void ddlcat_SelectedIndexChanged(object sender, EventArgs e)
{
    if (ddlcat.SelectedItem.Text == "Other...")
    {
        Response.Redirect("ManageCat-SubCat.aspx?Register=pnlCat");
    }
}

重定向到“Manage-Cat-Subcat.aspx”页面以显示 Panel2：

protected void ddlsubcat_SelectedIndexChanged(object sender, EventArgs e)

{
    if (ddlsubcat.SelectedItem.Text == "Other...")
    {
        Response.Redirect("ManageCat-SubCat.aspx?Register=pnlSubCat");

    }

}

这就是我在Manage-Cat_Subcat.aspx中尝试根据'Register'中的值显示

protected void Page_Load(object sender, EventArgs e)
{
    if (Request.QueryString["Register"] = pnlCat)
    {
        Panel1.Visible = true;
    }
    else if (Request.QueryString["Register"] = pnlSubCat)
    {
        Panel2.Visible = true;
    }

谢谢！

Answer 1

在ManageCat-SubCat.aspx中，您可以检查Request.QueryString["Register"]的值，并根据该值设置Panel2和Panel1的可见性

protected void Page_Load(object sender, EventArgs e)
{
    bool visible = Request.QueryString["Register"] == "pnlCat";

    Panel1.Visible = visible;
    Panel2.Visible = !visible;
 }

protected void ddlcat_SelectedIndexChanged(object sender, EventArgs e)
{
    if (ddlcat.SelectedItem.Text == "Other...")
    {
        Response.Redirect("ManageCat-SubCat.aspx?Register=pnlCat");
    }
}

protected void ddlsubcat_SelectedIndexChanged(object sender, EventArgs e)

{
    if (ddlsubcat.SelectedItem.Text == "Other...")
    {
        Response.Redirect("ManageCat-SubCat.aspx?Register=pnlSubCat");

    }

}

管理-CAT-Subcat.aspx

protected void Page_Load(object sender, EventArgs e) { panel1.visible=false; panel2.visible=false; if(Request.QueryString["Register"]=="pnlCat") { panel1.visible=true; } if(Request.QueryString["Register"]=="pnlSubCat") { panel2.visible=true; } }

如何使用Request.queryString从一个页面到另一个页面显示不同的面板？
