Answer 1

Hi,
From your description, my understanding is that you use
<asp:UpdatePanel>tag in your code, but it does not work well in browsers except
IE.
I have test
<asp:UpdatePanel>tag with code below, and it works well in IE, chrome, Firefox
as the screenshot.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
<ContentTemplate>
<asp:Label ID="lbl" runat="server" Text="Loaded" Visible="true"></asp:Label>
<asp:Button ID="btn" runat="server" OnClick="btn_Click"/>
</ContentTemplate>
</asp:UpdatePanel>
protected void btn_Click(object sender, EventArgs e)
lbl.Text = "BUTTON CLICKED !";
lbl.Visible = true;
The screenshot below is my result(the first is result in Chrome, second is in Firefox and last is in IE):
