Outlining the row which the mouse is over

[Peter]

I am using the CellMouseHoverEnter event to keep track of the mouse and the PrepareVeiwStyleInfo event to draw the border. One problem the event does not repaint the cells. It will only do that if it is the current row.

Here is the code im using inside the PrepareVeiwStyleInfo event

if (this._currentRowMouseOver == e.RowIndex)
{
e.Style.Borders.Top = new GridBorder(GridBorderStyle.Solid, ColorScheme.Rows.MouseOverBorder);
e.Style.Borders.Bottom = new GridBorder(GridBorderStyle.Solid, ColorScheme.Rows.MouseOverBorder);

if (e.ColIndex == 1)
e.Style.Borders.Left = new GridBorder(GridBorderStyle.Solid, ColorScheme.Rows.MouseOverBorder);
}

P.S. How can i draw a border on the right edge and is there a better way to do this?

TIA,

Peter

In CellMouseHoverEnter you could save the RowIndex that the mouse is hovering over in a variable and only when rowIndex for the event is different from the previously saved then you call InvalidateRange or RefreshRange so that the row gets repainted.

To draw the border on the right edge that should work:

if (e.ColIndex == ColCount)
e.Style.Borders.Right = new GridBorder(GridBorderStyle.Solid, ColorScheme.Rows.MouseOverBorder);

You should also handle the Control.MouseLeave event.

The way you implment this behavior with MouseHoverXXX and PrepareViewStyleInfo is reasonable.
