Use radGridView to display data

Hello, David,

You can display any data that you want in RadGridView. For the decimal and integer types, RadGridView uses GridViewDecimalColumn, while for the string type, there is GridViewTextBoxColumn. By default, RadGridView can generate its column types automatically according to the underlying data. More information about working with RadGridView is available here: 
Getting Started - WinForms GridView Control - Telerik UI for WinForms
Key Features - WinForms GridView Control - Telerik UI for WinForms

I hope this information is useful. Please let me know if you have any further questions.
