Hi, I hope you can help with this one.

I have implemeted a RadDatePicker alongside a number of bog standard ASP.NET text boxes. On each of these I have hooked up a required field validator and validator callout extender which fire on a button click.

If I leave the boxes empty, the validators sucessfully fire and identify which fields are not populated including the DatePicker. The callout is displayed on the first text box that is invalid. All good so far.

However when I tab between the boxes, the callout moves from box to box for the text boxes but doesn't display at all for the RadDatePicker inputs. Basically any time you give the date picker input focus, the validator call out doesn't display. This gives a really inconsistent feel for validation.

I'm using v.2008.01.0619.20 of the Telerik.Web.UI dll

This appears to be a problem that is specific to the Input control, not the date picker. RadNumericTextBox seems to have the same problem.

Any ideas?

Regards,
Glyn.

Hi Craig,

I tried to reproduce this however everything worked fine in my example (attached). The date-picker is populated initially with current date and if you delete this entry and try to tab the validator callout extender will work as expected..

Hi Vlad,

Thanks for getting back to me on this one. I agreed that the validator extender does work in some scenarios like the one you attached. The problem I described is when the RadInput is not the first input control that fails validation.

I have taken your example and extended to show what the problem is. Replace your default.aspx with this code. Scenario information is written in the default.aspx. Hope this will help.
