[CLOSED] Tab scroll with async postback

[tansu]

Hi,

I have a TabPanel inside updatepanel and I create tabs dynamically. Problem is, when I create tabs without postback (page get) tab scrollbars appears automatically if needed. This does not occur if I add a tab in postback. I set

tabPanel.EnableTabScroll = true;
tabPanel.LayoutOnTabChange = true;

and call tabPanel.DoLayout() but result is same. Is there a method like recheckscroolbars or something like that ?

Hi,

Do you have EnableTabScroll="true" initially? Or you set it dynamically? Can you provide simple test example?

Hi Vladimir,

I set it dynamically because I create TabPanel dynamically.
If I set it in aspx

<ext:TabPanel ID="TabPanel1" runat="server" Height="300" EnableTabScroll="true" />

It works, also in postback. If I set it OnInit;

protected override void OnInit(EventArgs e)
{
    TabPanel1.EnableTabScroll = true;
    base.OnInit(e);
}

No scroll bars. I also tried to derive a new class from TabPanel.

internal class DashboardTabPanel : TabPanel
{
    public override bool EnableTabScroll
    {
        get
        {
            return true;
        }
        set
        {
            base.EnableTabScroll = value;
        }
    }
}

So, what may be the problem ? Attach please find a sample.

Thanks.

I'm trying to figure out the problem Vladimir, can it be a css problem like overflow hidden ?

Hi,

You have to set Width (or put tabpanel inside layout) for TabPanel. Just set Width="500" for the TabPanel

Hi Vladimir,

But I don't set width if I set EnableScrollbars in aspx. It just works without setting a width.

There seems a bug. If you just set Height (not width) scrollbars appear.

No scrollbars:

<ext:TabPanel ID="TabPanel1" runat="server" EnableTabScroll="true" />

Scrollbars appear:

<ext:TabPanel ID="TabPanel1" runat="server" Height="300" EnableTabScroll="true" />

I set AutoWidth and problem resolved. Thanks.

Hi,

Ya, may be. We will look into it
Just I always try to keep a good rule: Define size explicitly or place the control in the layout. It can help to avoid many issues
