Tabs stop working after refresh

[Nik]

I've come across an issue where my TabStrip stops working in Firefox if the page is refreshed via F5 instead of ctrl-F5. I dont have a spot to test if it happens after postback or not. I'm aware that I dont need the JS function to switch tabs..it was just an attempt to fix the issue. I put an alert() in the JS and found its not going into the function at all after a F5 refresh. Do I need to run a reset function or something on the usercontrol pageload or maybe tooltip load? Again, this appears to only be a FF issue...IE works as expected. Using Version 2008.1.515.20.

<rad:RadTabStrip ID="radQPTabs" runat="server" MultiPageID="radmultipage" BorderWidth="0"
                OnClientTabSelected="onSelectedQuickPeekTab"  Skin="Vista">
                <Tabs>
                    <rad:RadTab Text="Price" Selected="true" Width="95px">
                    </rad:RadTab>
                    <rad:RadTab Text="Details" Width="95px">
                    </rad:RadTab>
                </Tabs>
            </rad:RadTabStrip>

function onSelectedQuickPeekTab(sender, args) {
    var tabs = args.get_tab();
    var strTabText = tabs.get_text();

    if (strTabText.indexOf("Price") > -1) {
        tabs.set_selectedIndex(0);
    } else if (strTabText.indexOf("Details") > -1) {
        tabs.set_selectedIndex(1);
    }
}

Hi Nik,

We tried to reproduce the reported issue using the latest versions of the controls, but to no avail. Please upgrade the controls in your application and let us know how it goes.

I failed to mention that the page with the tabstrip is a usercontrol that's loaded into a ToolTip. I made a test page with just the UC and it works fine after F5. Once the UC is loaded into the tooltip however, it stops working after F5 in Firefox. Does that mean its some issue with Ajax?

We're unable to upgrade at this time, as it would require a complete site QA.

Edit: I just changed the item thats loaded in the UC to one that has a RadComboBox in it as well. That also stops functioning after an F5. So it is definitely an ajax tooltip issue.

Hello Nik,

Unfortunately, the provided information does not help us much in reproducing the error. It will be best if you can open a support ticket and send us a simple running project (incl. CSS, images, skins, 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.

Sincerely yours,
Paul

Hi there,

I am having the exact issue here, the only difference is that I force a page refresh using Javascript. I am using the latest version 2015.2.623.40.

I have a multipage containing several IFrames and one of the Iframes have to refresh another one. So I cause a postback using this snippet

if (WebForm_PostBackOptions) {
            var val = true;
            if (arguments.length > 1) val = arguments[1];
            formSubmit(new WebForm_PostBackOptions("update_values", param, val, "", "", false, true));
        }
        else {
            __doPostBack("update_values", param);
        }

The param has a "rebindGrid" value (but I guess it doesn't matter).

In FF developer console I get this error

TypeError: n is null

Sometimes is "l is null" rather than n, but again I guess it doesn't matter.

The relevant source code is this

if(!($telerik.isIE7||$telerik.isIE8)){var n=getComputedStyle(s[q]),m=t=="offsetWidth"?(parseFloat(n.width)+parseFloat(n.paddingLeft)):parseFloat(n.height);

So it looks like something related to resizing an object.

Any chance this gives you a hint on how to solve the issue?

Thanks
