Hi Helmut,

First allow me to explain my setup:
I have a main form with a tab control on it. Each tab page contains a user control called ucTextArea. The tab pages are added dynamically whenever a user opens a new document. The ucTextArea user control contains the digital rune control. Doing it this way allow users to have multiple documents open at once on different tabs. This works great, but I want to enable my users to drag a text file from their "My Documents" folder onto the text area and it should open the file automatically. I'm having some problems with this.

Here's my code so far:
Firstly, I've set the Digital Rune control's AllowDrop property to True. Then I created two events, one called textEditorControl_DragDrop and the other is called textEditorControl_DragEnter, see the code for these events below:

private void textEditorControl_DragDrop(object sender, DragEventArgs e)
{
try
{
Array a = (Array)e.Data.GetData(DataFormats.FileDrop);
if (a != null)
{
string s = a.GetValue(0).ToString();
//Not sure if the blow is correct
frmMain.ActiveForm.Activate();

Open(s);
}
}
catch (Exception ex)
{
MessageBox.Show("Error in DragDrop function: " + ex.Message);
}
}

private void textEditorControl_DragEnter(object sender, DragEventArgs e)
{
// If file is dragged, show cursor "Drop allowed"

if (e.Data.GetDataPresent(DataFormats.FileDrop))
e.Effect = DragDropEffects.Copy;
else
e.Effect = DragDropEffects.None;
}

I also have a function called Open(string sFile), which opens the file:
public void Open(string sFile)
{
try
{
StreamReader StreamReader1 = new StreamReader(sFile);
textEditorControl.Text = StreamReader1.ReadToEnd();
StreamReader1.Close();
}
catch (Exception ex)
{
MessageBox.Show(this, ex.Message, "Error loading from file");
}

}

The problem is that this code just doesn't work. However if I implement the exact same code on the tab control, instead of the textEditorControl, then it works perfectly. But using it this way, the user MUST drag the file and drop on the tab, instead of the textEditor. I want them to be able to drag the file onto the Text Editor.

Do you maybe have any ideas on how to get this implemented properly? Any help would be appreciated.

Regards,
Francois
