[CLOSED] Combobox makes page with large image really slow
I have a simple page with a toolbar and a combobox. Underneath the toolbar is a huge image (3mb). The combobox makes the page super slow after it renders. Scrolling is slow, clicking on the combobox is slow, everything is slow. If I replace the combobox with a dropdownlist, everything is fast again.
<form id="form1" runat="server">
<ext:ScriptManager ID="ScriptManager1" runat="server">
</ext:ScriptManager>
<ext:Toolbar ID="Toolbar1" runat="server">
<Items>
<ext:ComboBox runat="server" ID="cb" >
<Items>
<ext:ListItem Text="Test" Value="Test" />
</Items>
</ext:ComboBox>
</Items>
</ext:Toolbar>
<ext:Image runat="server" ID="img" ImageUrl="anybigimage">
</ext:Image>
</form>
