Custom Edit Template validation for Delete

[rajeswari]

Hi,

      I have a Kendo Scheduler where i am using Custom Edit Template using e.TemplateName. So when i double click on the event in the Scheduler, the custom template opens as pop up with Save,Cancel and Delete option. I have some field validation in the template. When i click on Save, it shows validation error if any and does not proceed further if there are any validation error, but when i click on Delete, it shows validation error if any but it proceeds further and shows delete confirmation dialogue box. 

Can any one please tell me as how to perform validation check and prevent the delete operation from happening if there is any validation error.

 

Thanks,
Rajee

Hello Rajee,

The described behavior is expected. Basically, the validation errors are shown because the form inputs are blurred, but the deletion process does not require the form to be valid. The delete button will remove the event instance without the applied changes in the edit form. That is why the deletion is not prevented if there are errors and the Delete confirmation dialog is shown.

The only way to prevent this behavior is to disable the "Delete" button if there are any validation errors. Please note that deletion is not related to the valid entries in the form anyway.

Hello Georgi,

          Thanks for your reply. Can you please tell me as how to check validation on Delete button click. I have scheduler_remove event, but how do i check if the form is valid there?

Hello Rajee,

What you need to do is to get the Kendo UI Validator instance from the editor form:

• http://docs.telerik.com/kendo-ui/web/scheduler/how-to/getting-reference-to-the-validator

and check whether there are any errors. If there are any then you can prevent the deletion.
