Hey!

I am drawing a button in the header by the CustomDrawColumnHeader. When the e.Info.State is Pressed then I perform a click on the button.

The problem is that when the header is clicked the e.Info.State will be pressed every time the grid is rewritten (when setting a break point in the event). It have no effect to set the e.Info.State to Normal.

Here is the code I use :

        private void GridViewMy_CustomDrawColumnHeader(object sender, ColumnHeaderCustomDrawEventArgs e)
        {
            SimpleButton button = null;

             if (e.Column != null && (e.Column.FieldName.Equals("Yes") || e.Column.FieldName.Equals("No")))
             {
                 if (e.Column.Tag != null)
                     button = (SimpleButton)e.Column.Tag;

                  e.Info.State = drawCheckHeaderButton(e.Info.State, button, e.Column.Caption, e.Column.FieldName, e.Graphics, e.Bounds);
                  e.Handled = true;
              }
        }

private ObjectState drawCheckHeaderButton(ObjectState objectState, SimpleButton button, string columnCaption, string columnFieldName, Graphics g, Rectangle cellBound)
            Bitmap bitmap = null;
            ObjectState? returningState = null;
            try
            {
                if (button == null)
                {
                    button = new SimpleButton();

                    if (columnFieldName.Equals("Yes"))
                    {
                        button.Name = "btColumnHeaderYes";
                        button.Tag = CheckType.Ja;
                    }
                    else
                    {
                        button.Name = "btColumnHeaderNo";
                        button.Tag = CheckType.Nej;
                    }

                    button.Text = columnCaption;
                    button.Click += new EventHandler(checkColumnHeaderbutton_Click);
                    this.Controls.Add(button);
                }

                switch (objectState)
                {
                    case ObjectState.Hot:
                        if(!button.Focused)
                            button.Focus();
                        break;
                    case ObjectState.Pressed:
                        button.PerformClick();
                        returningState = ObjectState.Normal;
                        break;
                }

                button.Width = cellBound.Width - 1;
                button.Height = cellBound.Height;

                bitmap = new Bitmap(button.Width, button.Height);
                button.DrawToBitmap(bitmap, new Rectangle(0, 0, button.Width, button.Height));

                g.DrawImage(bitmap, new Point(cellBound.X, cellBound.Y));

                if (!returningState.HasValue)
                    returningState = objectState;

                return returningState.Value;
        }

How do I manage to run the PerformClick only once per click?
Is there maby a simpler way of getting a button in the header?
