  Is it possible to have a dropdown menu inside a custom column field? In other words, for each Task / row, the user will see a dropdown menu in the cell where they can select the value for that cell?

  Well, I totally forgot to include the control, etc. This question pertains to the WinForms GanttView control.

  Hello Jeff!

  Here, the trick is to show ComboList items of C1FlexGrid (which has been used as child control in GanttView controls) :

  private void Form1_Load(object sender, EventArgs e)
  {
         C1FlexGrid gridView = c1GanttView1.Controls[2] as C1FlexGrid;
         gridView.BeforeEdit += GridView_BeforeEdit;
  }
  
  private void GridView_BeforeEdit(object sender, RowColEventArgs e)
  {            
         C1FlexGrid gridView = sender as C1FlexGrid;
         gridView.BeginUpdate();
         if(gridView.Cols[e.Col].Name == "CustomColumn1")
                  gridView.Cols[e.Col].ComboList = "A1|A2|A3|A4|A5";
         gridView.EndUpdate();
  }
  

  In addition, below are few help links on C1FlexGrid :
