C#, winform
I have a DataGridView and a context menu that opens when you right click a specific column.
What shows up in the context menu is dependant on what's in the field clicked on - paths to multiple files (the paths are manipulated to create a full UNC path to the correct file).
The only problem is that I can't get the click working.
I did not drag and drop the context menu from the toolbar, I created it programmically.
I figured that if I can get the path (let's call it ContextMenuChosen) to show up in MessageBox.Show(ContextMenuChosen); I could set the same to System.Diagnostics.Process.Start(ContextMenuChosen);
The Mydgv_MouseUp event below actually works to the point where I can get it to fire off MessageBox.Show("foo!"); when something in the context menu is selected but that's where it ends. I left in a bunch of comments below showing what I've tried when it one of the paths are clicked. Some result in empty strings, others error (Object not set to an instance...).
I searched code all day yesterday but couldn't find another way to hook up a dynamically built Context Menu clickEvent.
Code and comments:
ContextMenu m = new ContextMenu();
// SHOW THE RIGHT CLICK MENU
private void Mydgv_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
int currentMouseOverCol = Mydgv.HitTest(e.X, e.Y).ColumnIndex;
int currentMouseOverRow = Mydgv.HitTest(e.X, e.Y).RowIndex;
if (currentMouseOverRow >= 0 && currentMouseOverCol == 6)
{
string[] paths = myPaths.Split(';');
foreach (string path in paths)
{
string UNCPath = "\\\\1.1.1.1\\c$\\MyPath\\";
string FilePath = path.Replace("c:\\MyPath\\", @"");
m.MenuItems.Add(new MenuItem(UNCPath + FilePath));
}
}
m.Show(Mydgv, new Point(e.X, e.Y));
}
}
// SELECTING SOMETHING IN THE RIGHT CLICK MENU
private void Mydgv_MouseUp(object sender, MouseEventArgs e)
{
DataGridView.HitTestInfo hitTestInfo;
if (e.Button == MouseButtons.Right)
{
hitTestInfo = Mydgv.HitTest(e.X, e.Y);
// If column is first column
if (hitTestInfo.Type == DataGridViewHitTestType.Cell && hitTestInfo.ColumnIndex == 6)
{
//MessageBox.Show(m.ToString());
////MessageBox.Show(m.Tag.ToString());
//MessageBox.Show(m.Name.ToString());
//MessageBox.Show(m.MenuItems.ToString());
////MessageBox.Show(m.MdiListItem.ToString());
// MessageBox.Show(m.Name);
//if (m.MenuItems.Count > 0)
//MessageBox.Show(m.MdiListItem.Text);
//MessageBox.Show(m.ToString());
//MessageBox.Show(m.MenuItems.ToString());
//Mydgv.ContextMenu.Show(m.Name.ToString());
//MessageBox.Show(ContextMenu.ToString());
//MessageBox.Show(ContextMenu.MenuItems.ToString());
//MenuItem.text
//MessageBox.Show(this.ContextMenu.MenuItems.ToString());
}
m.MenuItems.Clear();
}
}
I'm very close to completing this so any help would be much appreciated.
Thanks,
