Comments

Occurs when a part's action is triggered by the user.

An Action event occurs when the user clicks on the part. All parts except for the gap part (GapPartClass) generate this event.

If the Action event is used, the ItemClick event does not occur.

Examples

C#

            // Add a text part to the first cell (could use CellBaseClass.Text instead)
            CellClass cell = item.Cells[0];
            TextPartClass tp = new TextPartClass("The first cell", LineStyleEnum.Wordwrap, HAlignmentOptionalEnum.Left,
                         VAlignmentOptionalEnum.Top, Color.Blue, Color.Green, Color.Red, Color.Blue, new Font("Arial", 12), StringFormatFlags.LineLimit| StringFormatFlags.MeasureTrailingSpaces); 
            cell.Parts.Add(tp);
            // Followed by a check box (still in the first cell)
            CheckBoxPartClass cb = new CheckBoxPartClass( CheckBoxStateEnum.Unchecked, HAlignmentOptionalEnum.Left, VAlignmentOptionalEnum.Top, true);
            cb.Action += new GenericPartClass.ActionEventHandler(cb_Action);
            cell.Parts.Add(cb);
            // Followed by an image (still in the first cell)
            ImagePartClass ip = new ImagePartClass(img);
            cell.Parts.Add(ip);
            
            // Add contents to the second cell
            item.Cells[1].Text = "The\neasy\nway";
