Hi guys, I'm having a problem with cross paging. I have 2 different parent page and 1 child page. Both Parent pages contain a button that will navigate to the same page which is Child.aspx. But before proceeding to the child page, i need to have a server validation. <asp:Button ID="Button1" runat="server" Text="NEW REQUEST" Width="120px" PostBackUrl="~/purchaserequest/Child.aspx" />protected void Button1_Click(object sender, EventArgs e) { if(true){ return; } } protected void Button1_Click(object sender, EventArgs e)
