Gridview validation affects button on my form

[John]

I have cell and row validation happening on my grid which works fine. But when I have a cell or row that has invalid data, it locks out all my buttons on the window and prohibits the user from clicking them. I suppose that is alright for my 'OK' and 'Apply' buttons because I don't want to submit bad data. But I also have a 'Cancel' button which just closes the form without saving anything. I want that button always enabled even if the GridView is not valid.

Hello John,

This behavior comes from RadGridView's validation nature. Basically, if there is an invalid value in any cell, the gridview is stealing the focus in order to prevent any invalid data to get committed. This is why nothing outside of RadGridView can be clicked.

There is a feature request to introduce an API that allows you to change this behavior. You can find it logged in our feedback portal.

To avoid this behavior you can subscribe to the GotFocus event of the control that you want to get the focus (in your case the Cancel button) and call the CancelEdit() method of RadGridView.

private void CancelButton_GotFocus(object sender, RoutedEventArgs e)
{
    this.radgridView.CancelEdit();
}

On a side note, you can also take a look at the Cancel Edit On LostFocus article.

I hope you find this helpful.
