# 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

#### 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.
