[CLOSED] Problem with autoloading inner panel of tab

[jmcantrell]

I have a user control that I'm trying to embed in a tab panel. The user control is basically just a panel that autoloads a page. If I squash this into a single page and remove the extraneous panel, it seems to work, but this way, it doesn't. Here's a sample that illustrates it.

<script runat="server">

    Protected Sub TheButton_Click(sender As Object, e As DirectEventArgs)
        With ThePanel.AutoLoad
            .Url = "http://google.com"
            .Mode = LoadMode.IFrame
            .ShowMask = True
            .NoCache = True
        End With
        Tabs.SetActiveTab(TheTab)
    End Sub
    
</script>

<ext:TabPanel ID="Tabs" runat="server">
    <Items>
        <ext:Panel runat="server" Title="First Tab">
            <TopBar>
                <ext:Toolbar runat="server">
                    <Items>
                        <ext:Button runat="server" Text="Setup AutoLoad Tab" OnDirectClick="TheButton_Click" />
                    </Items>
                </ext:Toolbar>
            </TopBar>
        </ext:Panel>
        <ext:Panel ID="TheTab" runat="server" Title="AutoLoad Tab" Layout="FitLayout">
            <Content>
                <!-- This is where the user control is -->
                <ext:FitLayout runat="server">
                    <Items>
                        <ext:Panel ID="ThePanel" runat="server" Layout="FitLayout" AutoScroll="true" />
                    </Items>
                </ext:FitLayout>
            </Content>
        </ext:Panel>
    </Items>
</ext:TabPanel>

Hi @jmcantrell,

The TabPanel should have some height. Also please call a LoadContent method after the SetActiveTab call.

Tabs.SetActiveTab(TheTab)
ThePanel.LoadContent()

[jmcantrell]

Hmm. Yeah, I had .LoadContent() in my "real" page, but I was getting a javascript error when it was trying to call getLayout() on the panel. I don't think I can produce a sample that will get that, but is it possible that the page that is being autoloaded could conflict with that?

[jmcantrell]

For some reason, it didn't apply to this example, but taking Layout="FitLayout" off of the inner panel fixed the issue for my "real" page.

It is hard to say what can be wrong without a sample to reproduce. We would be happy to investigate a sample if you could provide.

By the way, it doesn't make sense to set Layout="FitLayout" and AutoScroll="true" at the same time. FitLayout stretches a content up to a container. But AutoScroll needs that a content size exceeds a container size.

Also I think that Layout="FitLayout" doesn't affect on a loaded iframe. But, anyway, it should not cause an error.
