There might be an easier way but you could always write your own “message box” to be invoked on the screen and build out the form to have a grid with data in it. I don’t know of an out of the box solution for a grid inside a message box. The other think you could do is build the data you’re displaying to look “grid like” with columns and stuff as a string, which might work
Maybe you can try the below: Erp.UI.EpiMessageBox.ShowLocale(“mustBeNumeric”, “mustBeNumeric_title”, MessageBox.Buttons.YesNo, MessageBox.Icon.Warning);
I didn’t realize customizations had using System.Windows.Forms; nor that I could add references to the Script class. This is exactly what I was looking for.
