WebTab™ supports validation of ASP validators in the selected tab by default. When the content pane has validators then before changing the selected tab or reloading the tab, the validators are checked. If the validation fails, then the selected tab does not change or reload. This feature can be disabled by setting the control’s EnableValidation property to False.
In HTML:
<ig:WebTab ID="WebTab1" runat="server" Height="367px"
Width="863px" EnableValidation=" >
<Tabs>
…
</Tabs>
</ig:WebTab>
In Visual Basic:
WebTab1.EnableValidation = false
In C#:
WebTab1.EnableValidation = false;
