Response.Redirect not working when using UpdateProgress

Question

I use an UpdatePanel and UpdateProgress.

Both Response.Redirect and JavaScript redirect window not working with them.

This code is working:

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdateProgress ID="UpdateProgress1" runat="server" DynamicLayout="true"
        AssociatedUpdatePanelID="UpdatePanel1">
    <ProgressTemplate>
        <asp:Image ID="ImageWait" runat="server" ImageUrl="../images/wait.gif" />
    </ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <asp:Button ID="ButtonSave" runat="server" Text="Save"
        OnClick="ButtonSave_Click" ValidationGroup="Valid1" />
    </ContentTemplate>
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="ButtonSave"
            EventName="Click" />
    </Triggers>
</asp:UpdatePanel>

Not working :

protected void ButtonSave_Click(object sender, EventArgs e)
{
    // Saved here

    Response.Redirect("../Main/Success.aspx");
}

Not working, too :

protected void ButtonSave_Click(object sender, EventArgs e)
{
    // Saved here

    Page.ClientScript.RegisterStartupScript(this.GetType(), "redirect",
        "location.href = '../Main/Success.aspx'", true);
}

How can I fix this ?

if you put a break point in the event handler does it reach it? I am guessing, not? — DaniDev, Oct 09 '17 at 22:00

@DaniDev yes, the compiler reaches the button line but the redirect not executed — Bengi Besçeli, Oct 09 '17 at 22:33
Async calls with redirects are not a good/safe practice because you are creating another thread which will be left orphaned when redirecting. If you are going redirect you don't need to create a trigger for it since it will not be updating the form. I recommend you just do a simple postback — DaniDev, Oct 09 '17 at 22:56
@DaniDev, okey thanks, so you say, async. calls may cause to injection, is it right? — Bengi Besçeli, Oct 10 '17 at 09:23
@DaniDev, how can I do a simple postback? If I refresh the same page, it does not work, too. — Bengi Besçeli, Oct 10 '17 at 11:44
a simple postback means that you user the event handler ("ButtonSave_Click") as you are and just remove the async trigger (the trigger is used to tell the form that it needs to update the Update Panel. BUT you are not updating the form, as you are redirecting. — DaniDev, Oct 10 '17 at 16:06
You have already accepted an answer but I am concerned that you are creating a problem for yourself which will manifest when you introduce this into production. If you wish I will post an answer which describes and explains what I am saying — DaniDev, Oct 10 '17 at 16:09
Yes I wanted to use a more secure way. I will ask a new question — Bengi Besçeli, Oct 10 '17 at 16:27
You don't really need a new question. I can just post an answer here if you like. Basically you just need to remove the Trigger and either one of your options above should work. — DaniDev, Oct 10 '17 at 16:31
where are the contents/ input controls that you are saving. Are there any other controls/triggers that trigger the Ajax functionality for your UpdatePanel ? — DaniDev, Oct 10 '17 at 17:51

You can use the ScriptManager

protected void redirector_Click(object sender, EventArgs e)
{
    ScriptManager.RegisterClientScriptBlock(this, GetType(), "redirect",
        "location.href = 'ListViewDemo.aspx';", true);
}

I had to change it to ScriptManager1, then it gets error with RegisterClientScriptBlock – Bengi Besçeli Oct 09 '17 at 22:32
ScriptManager is the class not the instance – hardkoded Oct 09 '17 at 22:33
Ok - it says, the name 'ScriptManager' does not exist in the current context. How can I define ScriptManager in code behind? – Bengi Besçeli Oct 09 '17 at 22:38
try `using System.Web.UI;` – hardkoded Oct 09 '17 at 23:15
