RadVirtualGrid does not support (nullable) booleans out of the box.
There are several pages to work around this issues, like:
In my humble opinion this should be supported by default. Why?
- The standard System.Windows.Forms.GridView supports it.
- The Telerik RadGridView supports it.
- Many example code show how to use RadVirtualGrid in combination with a database. And many database systems support the boolean (or bit).
- The RadVirtualGrid does support the datatype "Color". I hope you believe me when I say that a boolean is more commonly used than Color. (Again: Look inside a database)
In my mind I think of how a meeting would have been while designing the RadVirtualGrid.
- The team: "Shall we support integers?"
- The product owner: "Yes!"
- The team: "Shall we support strings?"
- The product owner: "Of course!"
- The team: "Shall we support Colors?"
- The product owner: "That would be wonderful!"
- The team: "Shall we support booleans?"
- The product owner: "Booleans? Nahh.... who needs booleans? Boolean are overrated!"
