RadTabStrip vanishes

[Mir]

I have a RadTabStrip containing some tabs and ScrollChildren is set true. Whenever there is a Multiline TextBox in any of the tabs, after focusing the Textbox or writing something on it, if I click on any of the tabs, the RadTabStrip disappears. It again shows after a single click anywhere on the screen! 
N.B. If I set ScrollChildren to false or make the TextBox singleline, this unexpected behavior vanishes! Have someone faced this weird error before? What is the way around!

Hi Mir,

Please try the below sample code snippet which works fine at my end. Try to replicate the issue in the provided code or provide a sample code if it doesn't help.

ASPX:

<telerik:RadTabStrip ID="RadTabStrip1" runat="server" Width="200px" ScrollChildren="true"
    MultiPageID="RadMultiPage1">
    <Tabs>
        <telerik:RadTab Text="Advanced" PageViewID="RadPageView1">
        </telerik:RadTab>
        <telerik:RadTab Text="Automatic Updates" PageViewID="RadPageView2">
        </telerik:RadTab>
        <telerik:RadTab Text="Remote" PageViewID="RadPageView3">
        </telerik:RadTab>
    </Tabs>
</telerik:RadTabStrip>
<telerik:RadMultiPage ID="RadMultiPage1" runat="server">
    <telerik:RadPageView ID="RadPageView1" runat="server">
        <telerik:RadTextBox ID="RadTextBox1" runat="server" TextMode="MultiLine" Rows="10">
        </telerik:RadTextBox>
    </telerik:RadPageView>
    <telerik:RadPageView ID="RadPageView2" runat="server">
        <telerik:RadTextBox ID="RadTextBox2" runat="server" TextMode="MultiLine" Rows="10">
        </telerik:RadTextBox>
    </telerik:RadPageView>
    <telerik:RadPageView ID="RadPageView3" runat="server">
        <telerik:RadTextBox ID="RadTextBox3" runat="server" TextMode="MultiLine" Rows="10">
        </telerik:RadTextBox>
    </telerik:RadPageView>
</telerik:RadMultiPage>

Thanks,
Shinu.

I also faced this problem. Tabs disappear when I enters any text in textbox with multiline mode and then click on other tab. The problem gets fixed handle OnClientTabSelected event. Do you have any idea why this problem occur? Do you have any other idea to fix this issue?

Hello Ekroy,

Could you please provide us with the proper implementation of the RadTabStrip that you use at your end, so we could perform some local tests and try to replicate the problem. In addition, could you specify which version of our controls are you using?
