Change the selection border

In GridListControl, normally selection border is in dotted line if you need to customize the selection border of the GridListControl, you can use GridBorder which can be achieved by using the PrepareViewStyleInfo event.

C#

this.gridListControl1.Grid.PrepareViewStyleInfo += Grid_PrepareViewStyleInfo;
void Grid_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
    //Change the selection border
    if (this.gridListControl1.HasControlFocus && this.gridListControl1.Grid.CurrentCell.HasCurrentCellAt(e.RowIndex))
    {
        GridBorder thinBorder = new GridBorder(GridBorderStyle.Solid, SystemColors.Highlight, GridBorderWeight.Thin);
        e.Style.Borders.Top = thinBorder;
        e.Style.Borders.Bottom = thinBorder;
        if (e.ColIndex == 1)
            e.Style.Borders.Left = thinBorder;
        if (e.ColIndex == gridListControl1.Grid.ColCount)
            e.Style.Borders.Right = thinBorder;
    }
}

 

VB

AddHandler Me.gridListControl1.Grid.PrepareViewStyleInfo, AddressOf Grid_PrepareViewStyleInfo
Private Sub Grid_PrepareViewStyleInfo(ByVal sender As Object, ByVal e As GridPrepareViewStyleInfoEventArgs)
    'Change the selection border
    If Me.gridListControl1.HasControlFocus AndAlso Me.gridListControl1.Grid.CurrentCell.HasCurrentCellAt(e.RowIndex) Then
        Dim thinBorder As New GridBorder(GridBorderStyle.Solid, SystemColors.Highlight, GridBorderWeight.Thin)
        e.Style.Borders.Top = thinBorder
        e.Style.Borders.Bottom = thinBorder
        If e.ColIndex = 1 Then
            e.Style.Borders.Left = thinBorder
        End If
        If e.ColIndex = gridListControl1.Grid.ColCount Then
            e.Style.Borders.Right = thinBorder
        End If
    End If
End Sub
