Tabstrip incorrect Firefox rendering when using custom images

[Ariel Molina]

All,

Im using a TabStrip/Multipage combination whose rendering is way off in Firefox.  I am not using any skins, instead just setting the image properties of each tab.  See below:

 <table width="951" align="center" cellpadding="0" cellspacing="0" border="0" >
            <tr>
                <td width="100%" style="padding-left:8px; padding-bottom:5px; FONT-SIZE: 18px; COLOR: #0580e9; FONT-FAMILY:ARIAL; font-weight:bold" colspan="2">
                    <asp:Label ID="lblTitle" runat="server"></asp:Label>
                </td>
            </tr>
            <tr>
                <td>
                    <radTS:RadTabStrip id="RadTabStrip1" runat="server" Skin="DifferentTabs" Width="691px"
                        OnTabClick="RadTabStrip1_TabClick" MultiPageID="RadMultiPage1" AutoPostBack="True"
                        CausesValidation="False" >
                        <tabs>
                            <radTS:Tab runat="server" Width="50px" Text="" SelectedImageUrl="Images/Quick Pricing/departure_info_rollover.gif" PageViewID="PageView1" Value="DepartureInfo" ID="Tab1" ImageOverUrl="~/Images/Quick Pricing/departure_info_1.gif" ImageUrl="Images/Quick Pricing/departure_info.gif"></radTS:Tab>

The width of the non-active tabs are shrinked only in Firefox.  Only the active tab renders correctly.

Hi Ariel,

Unfortunately, the provided information does not help us much in reproducing the error. I'm afraid we could not be of much help unless we reproduce the issue on our side. It will be best if you can open a support ticket and send us a simple running project (incl. your custom skin, CSS, images, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.

Best wishes,

The issue was actually due to the fact the IE browsers do not honor the "Width" property of the Tab instance, only FireFox does.  Setting the Width to that of the custom image, resolved the issue.
