Question

I have a Page that automatically generates a file and sends it to the Response. I need a Dialog to be shown during the file creation and hidden after the browser download dialog appears.
Any suggestion?

Thanks! 🙂

You can show a nice overlay busy message.

The Mark-up part:

$(function() { // when document has loaded

    ($.unblockUI); //unlock UI

    //Show busy message on click event and disable UI
    $('#btnHelloWorld').click(function() {
    $.blockUI({ message: '<h4><img src="busy.gif" />Please wait...</h4>' });

    });

});

<asp:Button ID="btnHelloWorld" runat="server" Text="Hello World" /><br/>

The Code behind:

   Protected Sub btnHelloWorld_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnHelloWorld.Click
        Label1.Text = "Hello World"
        Threading.Thread.Sleep(5000)
    End Sub
