I create a panel at runtime in a formS create at runtime.
I need to insert an XYChart inside the panel, how can I do it?
this is my code
Dim Pan As New Panel
Pan.Name = "Pan" & nFormChildId '(Is identity Numeric Form)
Pan.Size = New Size(500, 5000)
FChild.Controls.Add(Pan)
dim c as new XYChart(200,200)
c.name = "Chart" & nFormChildId IS NOT POSSIBLE
Pan.Controls.Add(c) ERROR NOT CONVERT IN CONTROL |

Hi Peter,
You can only put controls in a Panel. XYChart is not a control, it is the content. The control is WinChartViewer. So the code is:
' Put a control in the Pabel
Dim viewer As New WinChartViewer
Pan.Controls.Add(c)
' Put a test chart into the control so you can see it
Dim testChart as new XYChart(200, 200, &HFFFF00)
testChart.addTitle("Test Chart")
viewer.Chart = testChart
The relationship between the WinChartViewer control and the XYChart is analogous to the relationship between a Label control and a text String. The Panel needs to contain the "control" (WinChartViewer or Label), and the content (XYChart or String) is assigned to the control.
