Progress Telerik UI for WinUI
The UniformGrid is a responsive layout control which arranges items in an evenly-spaced set of rows and/or columns to fill the total available display space. Each cell in the grid is the same size by default.
The Telerik WinUI UniformGrid is highly customizable and offers different styling capabilities designed to help you align your application with design requirements.
You can also configure whether the first row or column remain hidden, the orientation of the grid, and whether the child elements placeholder for collapsed items is preserved or not.
