UniformGrid.MeasureOverride(Size) Method

Definition

Computes the desired size of the UniformGrid by measuring all of the child elements.

protected:
 override System::Windows::Size MeasureOverride(System::Windows::Size constraint);
protected override System.Windows.Size MeasureOverride (System.Windows.Size constraint);
override this.MeasureOverride : System.Windows.Size -> System.Windows.Size
Protected Overrides Function MeasureOverride (constraint As Size) As Size

Parameters

constraint
Size

The Size of the available area for the grid.

Returns

The desired Size based on the child content of the grid and the constraint parameter.

Remarks

The constraint parameter defines the maximum amount of space that is available for the grid. This space is divided up equally based on the number of rows and columns in the grid. The size of each child is measured to determine the maximum width of all the child elements of the grid. The maximum values cannot exceed the maximum cell size that is computed from the constraint. A desired grid Size is computed based on the maximum child dimensions. The Width is the maximum child width multiplied by the number of columns. The Height is the maximum child height multiplied by the number of rows. This method returns the desired Size.

For example, if there are two rows and four columns in a grid, the maximum height for each cell is 0.5*constraintHeight and the maximum width is 0.25*constraintWidth. For these calculations, constraintHeight is the Height value of the constraint parameter and constraintWidth is the Width value of the constraint parameter.
