C#

Primitive GetPrimitiveFromRowColumn( 
   int row,
   int column,
   Type primitiveType
)

Parameters

row

The zero-based index of the data row represented by the Primitive returned.

column

The zero-based index of the data column represented by the Primitive returned.

primitiveType

A requested Type to coerce the Primitive object into before returning it.

Remarks

Advanced developers may use this method from the application-level to access individual Infragistics.UltraChart.Core.Primitives.Primitive shapes that are used to render the chart graphics. Changing the size and position of Primitive objects outside of UltraChart may affect the informational content of the chart rendered. When the primitiveType is specified, any non-null Primitive returned can be safely typecast to the Type requested.

After directly manipulating the Primitive objects returned by this method, the developer must call InvalidateLayers to refresh the chart image.
