Examples

You can add a Grid with two rows and columns to the XAML as follows:

Or in C#:

Grid myGrid = new Grid();
myGrid.Width = 300;
myGrid.Height = 200;
myGrid.Background = new SolidColorBrush(Windows.UI.Colors.Blue);
myGrid.HorizontalAlignment = HorizontalAlignment.Left;

//We create and add the rows and columns:
//First column:
ColumnDefinition columnDefinition = new ColumnDefinition();
columnDefinition.Width = new GridLength(70, GridUnitType.Pixel);
myGrid.ColumnDefinitions.Add(columnDefinition);
//Second column:
ColumnDefinition columnDefinition2 = new ColumnDefinition();
columnDefinition2.Width = new GridLength(1, GridUnitType.Star);
myGrid.ColumnDefinitions.Add(columnDefinition2);

//First row:
RowDefinition rowDefinition = new RowDefinition();
rowDefinition.Height = new GridLength(40, GridUnitType.Pixel);
myGrid.RowDefinitions.Add(rowDefinition);
//Second Row:
RowDefinition rowDefinition2 = new RowDefinition();
rowDefinition2.Height = new GridLength(1, GridUnitType.Star);
myGrid.RowDefinitions.Add(rowDefinition2);

//Do not forget to add the Grid to the visual tree.
