Question

Is it possible to define multiple combo-boxes in the grid of the gant with different values?

For example:
Column 1: Color (red, green, blue)
Column 2: User (User1, User2, User3)

When yes -> how to I have to define the combo-boxes?

Answer

The ComboBox values should be added to just before the combobox-edit-cell goes into edit mode.
The correct event to use is the Grid.OnBeforeEditCell

One possible implementation of this event looks like this:

private void grid1_OnBeforeEditCell(PlexityHide.GTP.Grid grid, PlexityHide.GTP.BeforeEditEventArgs beforeEdit)
{
  if (beforeEdit.Cell.Content is ComboText)
  {
    (beforeEdit.Cell.Content as ComboText).EditBox.Items.Clear();
    (beforeEdit.Cell.Content as ComboText).EditBox.Items.Add("Item 1");
    (beforeEdit.Cell.Content as ComboText).EditBox.Items.Add("Item 2");
    (beforeEdit.Cell.Content as ComboText).EditBox.Items.Add("Item 3");
    (beforeEdit.Cell.Content as ComboText).EditBox.Items.Add("Item 4");
  }
		
}

Note; in early versions of GTP.NET the beforeEdit.Cell.Content returned null in the OnBeforeEditCell event, get the latest patch to fix this issue
