Hello Peter,
I have used ms visual studio powerpack line shape to draw fibonacci retracement, fibo fan, box etc in vb 2008 project. Everything worked well but suddenly i noticed that tooltip that showed up when mouse is over a candlestick or other indicator line-- is not showing.
Other mouse move, hover events of chart viewer is working fine.
Dim canvas as new ShapeCollection
canvas.Parent= WinChartViewer1
These 2 lines are creating the problem, but necessary for drawing line shapes.
Could you please provide a solution? |

Hi Mahbub,
I have tried myself. I found that the ShapeContainer will disable tooltip for any control that is covered.
For example, if you have a standard .NET Label control, and assign a tooltip to it, then when the mouse is over the Label control, it should display the tooltip. However, if you also have a ShapeContainer and set the Label as its parent (which means the ShapeContainer will cover the Label), then the Label will no longer show tooltip. If I set a tooltip to the ShapeContainer, the tooltip of the ShapeContainer may get displayed when the mouse is over the ShapeContainer (and therefore is also over the Label).
So I think it is a feature of the ShapeContainer to disable tooltips on other controls covered by it. In other words, the issue is not related to ChartDirector, but occurs to all controls and is a feature of the ShapeContainer.
