Grid Column validations

[Rebeca]

Hi!
I have been using validation properties (required, max length, validationMessage etc) for the forms.

Is there any way to have the same functionality for Grid component to have validations in the  Columns?

As they are free inputs for the users too, 
would be nice if you can provide some examples to know how to handle them.

Thanks for your time,
Rebeca.

Hello, Rebeca,

The validation in the Grid is done using custom cells.

There are a couple of options for this:

- Render a custom cell where the editor for the cell will have its own validation attributes like required, min, max, etc:

- Another option is to validate the input value dynamically on the item change event and mark the value as invalid and then add styles to the cell to indicate that

I hope this helps.
