Parameter.Value Property

Specifies the current value of the parameter.

Namespace:DevExpress.Diagram.Core.Shapes
Assembly:DevExpress.Diagram.v19.1.Core.dll

Expanded Syntax

Property value

Type: CriteriaOperator
A numerical value that is the current value of the parameter.

Expanded Remarks

Each parameter is characterized by its Value property. The DefaultValue property returns the initial value.

To pass the current Point to the Value definition, use the P.X and P.Y variables that correspond to the point's X and Y coordinates.

The code snippet below illustrates how to define a parameter that changes its value from 0 to 1 depending on its current Y coordinate. An end-user cannot change the X coordinate.

You can pass the parameter's value to the CreateSize method. The P0 variable corresponds to the first parameter within the ShapeTemplate.Parameters collection, the P1 corresponds to the second parameter and so on. The code snippet below illustrates how to use this parameter to allow an end-user to transform the shape by changing the Arc segment's size.

The following image shows the result:
