Can you change the celldropdown button?

Hello Jing,
   Is there way to change the celldropdown button? I think maybe onpaint you can change it. I would have to make my own control and change the onpaint for the dropdown button. or can just change the color and make it flat?

Hi Shane, you can overwrite the OnPaintDropdownButton method to draw your custom drop-down button, here is an example:

C#:

class MyDropdownListCell : DropdownListCell
{
	protected override void OnPaintDropdownButton(CellDrawingContext dc, unvell.ReoGrid.Graphics.Rectangle buttonRect)
	{
		dc.Graphics.DrawRectangle(Pens.Black, buttonRect);
	}
}

VB.NET:

Class MyDropdownListCell
	Inherits unvell.ReoGrid.CellTypes.DropdownListCell

	Sub New()
		MyBase.New()
	End Sub

	Protected Overrides Sub OnPaintDropdownButton(dc As CellDrawingContext, buttonRect As Rectangle)
		dc.Graphics.DrawRectangle(Pens.Black, buttonRect)
	End Sub

End Class
