Nested Control Validation

[Neil]

I have a Telerik RAD Editor in a user control, so I can set defaults in one place to enable me to reuse the control where ever I need a rich text editor. When I add it to a page I want to validate the content property of the editor by using a RequiredFieldValidator control to ensure that the editor has content.

When I load the page I get,

"Control 'radEditor' referenced by the ControlToValidate property of 'ValidateEditor' cannot be validated."

After some research, I discovered decorating the class with [System.Web.UI.ValidationProperty("RadEditor")] will expose the validation property in the markup page, but when I add this attribute, the page doesn't throw the above error, but it is not respecting the RequiredFieldValidator hooked up to the control when I submit the page without content.

Any ideas?

Thanks,
Neil

Hello Neil,

The validators should validate controls on the same form but not a control placed in a UserControl , because the UserControl could contain multiple other controls and html elements and the validator will be unable to validate all of them when setting its ControlToValidate value to the name of the user control.

That is why our suggestion is to not use this approach or put the validators directly inside the usercontrol's ascx file.
