Apply validation in addin dock pane using wpf by arc pro sdk

[AbdelrahmnanMohamed]

I am a developer making a custom tool, my tool has 2 text boxes, I want to make both of them required and mandatory to be not empty and I want also to make a red star (*) above them as they made in esri geo processing tools, any idea for that please??

Hi, 

You should implement the INotifyDataErrorInfo interface in your view model class. Please refer to

https://social.technet.microsoft.com/wiki/contents/articles/19490.wpf-4-5-validating-data-in-using-t... for more information and examples.

For red star (*) you should make 2 texbox'es inside grid or stackpanel. One of them preset text "*" and make Foreground = "red". Second textbox will show field label with esri style. 

If you want to make universal dialog for different database table records you should bind "*" textbox visibility to database field property.
