I have an asp.net application, where the user would click a button and launch another page (within the same application). The issue I am facing is that the original page and the newly launched page should both be launched.
I tried response.redirect, but that tends to unload the original page.
This button post to the current page while at the same time opens
OtherPage.aspx in a new browser window. I think this is what you mean with
...the original page and the newly launched page should both be launched.
<asp:Button ID="myBtn" runat="server" Text="Click me" onclick="myBtn_Click" OnClientClick="window.open('OtherPage.aspx', 'OtherPage');" />
