Change Color Visio shape programatically in c#

i want to change the color of a BPMN-Shape in Visio by Code. What i've done so far is changing the value from the "LineColor" Cell of the ShapeSheet in Visio with the following code-snippet: 

 _startShape.CellsU["LineColor"].FormulaForceU = "=RGB(255,0,0)";

However, Shapes that I drawed myself are not changing in color. The Information/Value in the ShapeSheet-Cell is changing but the color is still not visible. I read about the GUARD-function which is protecting the cells, but the FormulaForceU should ignore the GUARD.

Imported Shapes are changing as expected! Just the self-drawed are not changing to red (RGB(255,0,0).

I can't figure out why! Has anyone experienced the same?

Thanks in advance!

Solution

  • If the shape is a group, then you need to change the sub-shapes as well.
