Roy Lambert NLH Associates ![]() | No answer in the TMS newsgroups so anyone here have a suggestion?
Drag'n'Drop is easy a row at a time. I use a mousedown event to call BeginDrag on a double click. However, when there are multiple rows selected the selection is lost before dragging is started. Think Outlook Express and dragging emails from one mailbox to another. Does anyone have a solution or suggestion? Roy Lambert |

I have goRowSelect=true, dragmode=dmManual and beginDrag(false, 10) in the OnClickCell handler (thanks to earlier posters for that tip). Grid version is 3.1.0.2 There are 2 problems. 1. When the row is dropped on the second grid, SelectedRowCount is zero for the source grid even though a row is visibly selected. 2. If I select multiple rows, clicking the mouse to try and start the drag clears the selection for all but the row under the mouse. ------------------------ Newsgroups: tmssoftware.grids Subject: Re: Multi-row drag&drop From: "Bruno Fierens [tmssoftware.com]" <_nospam_@tmssoftware.com> Date: Wed, 17 Jan 2007 11:33:53 +0100 > 1.

This is normal, SelectedRowCount only applies for disjunct row selection mode, otherwise, use grid.Selection.Bottom - grid.Selection.Top > 2.

Demo 28 at http://www.tmssoftware.com/go/?advgrid2 shows how this can be done. -- Kind regards, Bruno Fierens TMS software Productivity components for Windows, .NET, IntraWeb development http://www.tmssoftware.com There's only one rule and that is to do.

Thanks for that. I searched for messages with both drag and drop and so missed it. Example 28 uses OLE but I'll see if I can massage it to do what I want. Roy Lambert |

Just so you know, and in the hope someone else has a solution (possibly a google search I haven't tried yet). Demo 28 uses OLE to copy between two grids. Both components need OLE enabling and my TreeView hasn't. Roy Lambert |

Well perhaps you can fiddle around with the clipboard - Ctrl-C with a few rows selected allows pasting the selected rows into EditPad, so what about trapping the OnMouseDown before it de-selects the other rows, copying everything to the clipboard if several rows are selected and setting a flag in case the user wants to drag, and then in OnDragDrop checking for the flag and pasting? -- Chris (XP-Pro + Delphi 7 Architect + DBISAM 4.25 build 4 + EDB 1.04 build 3) |

That's one of the things I'm trying - I thought I'd found the right place to do it but it has consequences elsewhere. It may not be possible without altering quite a lot of TMS's code in which case my fallback is a button - click it and it fires off grid.BeginDrag(True) which works but its not "nice". Thanks for trying. Roy Lambert |
