Hello Support Team,

I added in chart the DragPoint Tools. I want to process event of the end of drag. How to make it ?

Best regards, Rustam.

Hi Rustam,

An specific event for that doesn't exist but you can easily achieve that by using TeeChart's OnMouseUp event and the series Clicked method as shown here:

Code: Select all

Private Sub TChart1_OnMouseUp(ByVal Button As TeeChart.EMouseButton, ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
    If (TChart1.Series(0).Clicked(X, Y) <> -1) Then
        MsgBox "Point Dragged!"
    End If
End Sub

Alas! It not quite that. I have event each time when the cursor is crossing the series line.

Hi Kabal,

It works fine here, it only fires after a series point has been clicked and the mouse button is released. Are you sure that you didn't implement the code in the OnMouseMove event instead of OnMouseUp?

It's not working when You have started drag from "clicked" point in the Series but have stopped drag on free region. Then Clicked return -1 however the point have been moved.

Hi Rustam,

yes, in that case, if you want to control this you will have to use the OnMouseDown, OnMouseMove and OnMouseUp events checking on these ones which point was clicked when the mouse is released.
