I'm having problems with the report control layout using it in a dialog.  I'm using it as a replacement for a CListCtrl, so that I can set font / styles / colours etc per cell.

 

If you set SetAutoColumnSizing(FALSE), so that resizing columns kinda behaves itself (i.e. only resizes the column you are resizing), then if you make the headers wider than the window (I'm using the control inside a dialog, so it's restricted in size) it displays a scrollbar. 

 

The scrollbar doesn't respond to any mouse events, so you can't actually scroll to see the final columns, which makes for an unpleasant user experience.

 

Also if the total columns doesn't add up to the width of the control, then the final gap is exactly that - a gap: no gridlines.  It's a bit ugly.

 

So is there a workaround for this?  Do I have to add an empty column at the end or something?  And what about scrolling?

 

Thanks

thanks for your reply.  I'm having problem with vertical scroll as well.  Basically the scroll-bars don't seem to get messages.  If I click in the control and use the mouse-wheel it scrolls, but the scroll-bar itself ignores mouse events.

 

My code is like this

 

in the DIALOG RC file, I have created a frame items.  it has styles WS_NOTIFY, WS_VISIBLE, and WS_EXCLIENTEDGE

 

then in the dialog class, I use

 

DDX_Control(pDX, IDC_REPORTCONTROL,  m_Schema);

 

This then creates the control with the styles that the control in the dialog resource has.  To draw I use

 

 CXTPReportColumn* pFirstCol = new CXTPReportColumn(0, "Symbol", 180, FALSE);

 m_Schema.BeginUpdate();
 
 m_Schema.AddColumn(pFirstCol);
 m_Schema.AddColumn(new CXTPReportColumn(1, "Type", 70, FALSE));
 m_Schema.AddColumn(new CXTPReportColumn(2, "Access", 70, TRUE));

 pFirstCol->SetTreeColumn(TRUE);

 m_Schema.AddRecord(...);
 m_Schema.AddRecord(...);

etc

 

 m_Schema.Populate();

 m_Schema.GetSelectedRows()->Clear();
 m_Schema.EndUpdate();
 m_Schema.RedrawControl();

 

 

I suspect if I explicitly call Create on the control it may get the scroll-messages but I haven't tried that one yet.

 

couple of things I don't like.

 

1. Have to call Clear() on GetSelectedRows, else the control selects row 1 by default, which paints it grey.  by default nothing should be selected until a user explicitly selects it.

 

2. Clicking outside a row in the control doesn't reset the selected rows either.  It would be nice if it did, otherwise I have to add a notify handler to do this.

 

3. The tree control mode doesn't use standard tree control layout.  specifically an expand/contract glyph has an "elbow" line coming into it from the side rather than a straight one down from the top the top (as in a tree control), and the line style is not settable (i.e. can't do dotted lines like a real tree control).

Down-side is I'm having trouble setting extended styles on the control now for its border.  I'm calling Invalidate() to get it to redraw, but it wont.

 

not until I expand a tree item in the report - then it displays the border on the control.  It's driving me nuts.

 

Also, I tried setting autosize off on some columns, but now I can't manually resize them either?  what's with that?  Surely turning off auto-resizing should do that, and that alone - not disable sizing altogether.

 

Need to add a CreateEx call to the report control.
