Validate value in a property grid panel using custom editor

[dattd]

Hi,

I have a case as below.
Create a Property Grid Panel
Add add a custom editor, a TextField
When an invalid value is entered, I explicitly call markInvalid method of the text field above that will show the validate error message properly. However, When I select another row or click on anything else, the text field is hidden and all the error message's gone.

My question is: how to mark a value cell of a property grid as an invalid value?

Best Regards,

Are you using Ext.grid.property.Property? If so then you can use the validations on that
