I can open another window to display some stuff, but then I cannot use the buttons on the original page anymore. Why is this and how to fix it? This is my code:
<asp:Button ID="Button_ViewSimpleRequest" Text="Simple Request" runat="server" OnClientClick="window.document.forms[0].target='_blank'" PostBackUrl="~/xyz.aspx" />
<asp:Button ID="Button_Self" Text="Self" runat="server" OnClientClick="window.document.forms[0].target='_self'" />
After clicking the first button, the second button also redirects to xyz.aspx. How do I make the second button behave like a normal button on the original page?
