public static variables should do the trick.

Hi,

Here is the code snippet:

System.Diagnostics.Process p = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo sinfo = new System.Diagnostics.ProcessStartInfo();

sinfo.FileName = @"C:\WINDOWS\system32\calc.exe";
p.StartInfo = sinfo;
p.Start();

Thanks,

Drag and drop databound treeview WPF

10-Jun-07 0:02

Hi,
Any idea how to directly show child table when clicking on the bloody parent collapse button in a datagrid control?? Do we always have to see the bloody relationship name link and click on it to open the child?? Can we hide the bloody toolstrip from the top of the child table?? Is there any other way to view datagrid table in more friendly way, say, have more than one child open simultaneously.. Is the bloody datagrid control that bloody??

Thanks for reading my bloody post;)

Yesterday I had a great experience designing an application in WPF. It's really cool to see how easy it was to create a databound treeview. However, I want to drag nodes within the treeview.

So far I did the following:

- Implement a mousemove eventhandler that initiates the drag operation
- Implement a dragover eventhandler to check if a dragged item can be dropped
- Implement a drop eventhandler that moves the item.

However the last eventhandler proves to be problematic. Although I have the correct data, I can't seem to grab the treeviewitem that th mouse is currently over. Anybody knows how I can get this?

Try searching through articles, I remember running across a good one dealing more or less with your issue just this week but sorry I cant remember the title not the author.

Found an article explaining a dragdropmanager for a listview: http://www.codeproject.com/WPF/ListViewDragDropManager.asp[^]

Going to read that and see if it fits my application as well.

Unfortunatly that one is for Windows Forms, however I did manage to get a bit further with detecting the item that the source item is being dragged on. Now to fix the last bugs, because now it seems as if the MouseMove event is no longer fired if you iniated a drag operation.

datagridview windows application hyberlink

10-Jun-07 1:22

As it turned out the solution was moderatly simple.
I had to do the following in the drop eventhandler:

Task t = (Task)e.Data.GetData(typeof(Task));
            
_currentMousePosition = MouseUtilities.GetMousePosition(taskTree);
HitTestResult result = VisualTreeHelper.HitTest(taskTree, _currentMousePosition);

if (result.VisualHit is FrameworkElement)
{
	_targetTask = (result.VisualHit as
	FrameworkElement).DataContext as Task;

}

After that it's just removing the task from the original parent and add it to the new parent. Pretty easy Big Grin | :-D

Too bad the mouse handling in WPF sucks, because I had to rely on Josh Smith's MouseUtilities class to get the actual mouse position relative to the treeview. Maybe I will build a dragdropmanager for the treeview similar to the one Josh created. It makes life a lot easier.

I'm writing a program that is a shortcut in the windows sendto directory. When the user sends too many files the program won't even load so I can't even warn the user of the problem. I think it's based on the size of the full path of each file. Does anyone know a way around this? Thanks a million.
