Update a label on aspx page before a Response.Redirect

Question

I have the following redirect but need to change the label to say "Success" before the re-direct:

Response.Redirect(Url)

I've tried passing in false and then changing the label.Text = "Success"

Also tried saving a value like this

What you need is a way to save data during transition. So the first time the validation is passed store the values into Session variable without success.

Session ("label") = "Success
Response.Redirect(Url, False)


Label.Text = Session("label")

Is the only way to do this through a java script?

Would I use:

Page.ClientScript.RegisterClientScriptBlock

Answer 1

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "anyKey", "<script>alert('Success'); window.open(" + url + ");</script>", false);

or if you want to open the url when user presses ok button on your message box, you can also do it like this

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "anyKey", "<script>if(confirm('Success')) window.open(" + url + ");</script>", false);

also, as Aristo says above

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "anyKey", "<script>$('#"+ lblYourLabel.ClientID +"').val('Success'); var t=setTimeout(function(){window.open(" + url + ");},3000);</script>", false);
