Drag Grid Textbox to Another Column

[Auguy]

I'm trying to set up the ability to drag a text box form one column to another. I don't actually want to move the control, just remember what row/col was dragged and what column it gets dropped in. Each column represents a completion date in a project and there are some other housekeeping chores that need to be done before I complete the move. I only care at this point as to what column it was moved to. I'm close to getting this to work using the Grid DragDrop and Drag methods. I have two questions. Can I use the OleDragDrop methods, etc. and would that be a better way to go? Or, would I be better off trapping the mouse events and do my own drag/drop because this is entirely within the grid?

You're pretty much always better off using OLE drag-and-drop rather than the native stuff, because it gives you more control over the whole process.

Auguy,

Yes, I definitely agree with Tamar. And note that you can't mix the two methods. It has to be one or the other. The OLE drag-and-drop technique is the way to go with this.

There's a lot of information on this subject in the VFP Help. Start with the topic "Dragging and Dropping Data", and navigate from there.

Thanks to both of you. I have it working with the old DragDrop. Will see if I can re-do with ole.

Auguy,

If you have any specific questions, come back here. OLE Drag-and-Drop is reasonably straightforward, but there's a lot of details that can catch you out.

Back sooner than I expected. I thought I had the old DragDrop working, but noticed the double click on the textbox is no longer working. I have the DragMode set to Manual and the code to start the drag in the MouseDown event. Is there any way to have both of these working at the same time? Maybe a timer to see if the user has double clicked.

Ok, thought I had a way around it again. Tried using a timer (enabled in the mousedown event) to see how long the mouse was held down, but the timer doesn't start until the mouse up.

Switch to OLE drag-and-drop and set the lDetectDrag parameter of OLEDrag to .T. It handles this problem for you automatically.
