I added a snapping to a custom tool and trying to change a snap tip with ISnappingEnvironment.SnapTipSymbol Property
public override void OnMouseMove(int Button, int Shift, int X, int Y)
snapResult = m_Snapper.Snap(m_CurrentMouseCoords);
//Update the snapping feedback.
if (snapResult != null)
(m_SnappingEnv.SnapTipSymbol as IFormattedTextSymbol).Text = "Changed";
public override void Refresh(int hDC)
if (m_SnappingFeedback != null)
It does not update the actual tip.
In the help ESRI says that
"You have a number of options to customize the tip symbol, including advanced text capabilities provided by IFormattedTextSymbol to provide options for backgrounds, offsets, or right-to-left text capabilities. "
Any help will be appreciated.
