How to set WPF component height to "*" in code?

Question

I want to set a component height to "*" dynamically in code. How can I do that?

I know how to set it to a defined value:

DataGrid.Height = "500";

And how to set to "Auto":

DataGrid.Height = Double.NaN;

Star sizing only exists for very few components, the Grid itself is not one of them. GridLength has a constructor which takes the type of the sizing sheme as parameter.

If you want a component to stretch do not set any value for Width/Height and make sure the Horizontal/VerticalAlignment is Stretch.

You can also do this using the columndefinitions/rowdefinitions with GridUnitType, for example :

RowDefinition rd = new RowDefinition();
rd.Height = new GridLength(1.0, GridUnitType.Star);
grid.RowDefinitions.Add(rd);
