How to change radtab style on failed validation

[Mac P]

Hello

I have radtabstrip that loads usercontrols in dynamic radpageviews. Each user control has different validation groups. On  validation failure i need to indicate user to go ahead and fix validation errors on other tab in wizard.
For e.g. if user goes from tab A to tab C and save it i need to display validation error on tab B. For that i need to either add Red Exclamation Mark or change the font of tab to red or tab the entire tab color to red.

Any idea how do i do that? I am using custom skins.

Regards

Hello Mac P,

I suggest you set CssClass property of the tab that fails the validation. Please check this online example which shows how to do this.

The posted link for the online example no longer works. I'm assuming it is now the demo page here: http://demos.telerik.com/aspnet-ajax/tabstrip/examples/appearance/uniquetabappearance/defaultcs.aspx. However I'm not seeing any way to set the CssClass of a tab that has failed validation. Is this functionality that has been removed? I can't find a way to change a tab's appearance when validation has failed.

Also, that demo appears to be broken. I've looked at it in IE, Firefox and Chrome; the CSS seems to be really messed up in every browser and the demo doesn't show off the various states the tabs can be in.

Hi Ben,

Yes the demo has been moved to the page that you have found. It does not show how to customize RadTabs on validation failed, but it shows how one can use the CssClass property of the RadTab to customize its appearance. Currently the demo has some broken styles due to recent changes in our demos implementation.

In order to change the CssClass of a RadTab, you could use both the client-side and server-side API, depending on where your validation has been implemented.
