title: How to set DataGridView columns text format to uppercase by adding new property?
body: <p>I have a custom DataGridView control and want to set the text format for custom columns in the designer (CellStyle builder). </p>
  
  <p>Let's say I want to make the text format to uppercase. After searching about this I've found some solutions with adding new events and then changing the text format but this is not what I want. I want to add a new property to all designed columns and there set or change the text format. </p>
  
  <p>How to do this?</p>
  
  <p>Thank and best regards.</p>
