Hi, all,
I'm using the C# sample code for TrackControl,
I want to get the block's length, my code is
XtremeReportControl.ReportRecord R = wndTrackControl.Records[2];
XtremeReportControl.TrackControlItem T = (XtremeReportControl.TrackControlItem)R[3];
MessageBox.Show(T.BlockCount.ToString());
MessageBox.Show(T.Block[0].Length.ToString());
T.BlockCount is 5, it's OK. But the T.Block[0].Length shows error.
Could anyone help me?
Thanks!

Hi,
Below is some VB code that can be used to get the length of the block, hopefully you can port this to C#.
Private Sub TrackControl_MouseUp(Button As Integer, Shift As Integer, x As Long, y As Long)
Select Case TrackControl.HitTest(x, y).ht
Case xtpHitTestBlock
Debug.Print TrackControl.HitTest(x, y).Block.Length
End Select
End Sub
|
Hope this helps.

Hi, Xander,
Thank you for your answer.
But I want to get all block's length in the TrackControl, this way is not suitable for me
Anyway, thank you very much.

Hi,
It looks like there's no way to iterate through each Block within the TrackControl, the only thing I could find was "For Each Block In TrackControl.SelectedBlocks", but this is only useful if you select the blocks first.
It looks like if you require this you'll need to put in a request for this functionality.

Hi,
I know this has been a while but I have found a way to interact with the Blocks after they're created.
In VB I created a global variable as "Dim Block() As TrackBlock"
Then as I added each block initially I added them to this variable incrementing the Object array each time, therefore once created you have access to the blocks lengths at anytime and you can iterate through the entire block collection.
I have only found this out as I am trying to do something similar for the following post: http://forum.codejock.com/forum_posts.asp?TID=19708&title=trackcontrol-using-markup - http://forum.codejock.com/forum_posts.asp?TID=19708&title=trackcontrol-using-markup
