Cellvalidating cancel

14-Mar-2020 05:55

Hello I am using a 3rd party button (Pay Pal) and in some cases I need to cancel the click event from going on.I use the Public Event ".click" to do the checks but cannot find how to cancel the event from that point... this is an answer for the person who is over me Yes it doesnt work because e.cancel = true isn't property of under button_click event. Validate() Because the Binding Navigator doesn't cause validation, it is postponed until here, Validate() performs the last validation and returns the result.

Except that I pop a message box in the click event after the update statements have been successfully executed (they're in a try catch construct) to say Save completed.

You can validate data by handling the Cell Validating event, which is raised by the Data Grid View when the current cell changes.

In this walkthrough, you will retrieve rows from the column and tries to leave the cell, the Cell Validating event handler will examine new company name string to make sure it is not empty; if the new value is an empty string, the Data Grid View will prevent the user's cursor from leaving the cell until a non-empty string is entered.

Please note that event fires only when changing the cell value using the user interface.

This method will not fire when setting the cell value with code. Greetings, Jack the Telerik team Thank you for the reply.

When you display data entry functionality to users, you frequently have to validate the data entered into your form.
