You can set the RadGridView.AutoSizeRows property to true in order to size all rows automatically according to the content. However, this will affect the header row along with the data rows. It is possible to specify a certain height for the header by setting the RadGridView.TableElement.TableHeaderHeight property.
I hope this information helps. Should you have further questions I would be glad to help.
