How to avoid selection backcolor for particular cells in WinForms GridGroupingControl?
Avoid select the backcolor
By default, the SelectionBackColor will override the BackColor of the cell. In order to avoid SelectionBackColor override the BackColor of the cell in WinForms GridGroupingControl, the TableControlDrawCellDisplayText event can be used to draw the color on the cell.
C#
//Triggering the event.
this.gridGroupingControl1.TableControlDrawCellDisplayText += new GridTableControlDrawCellDisplayTextEventHandler(gridGroupingControl1_TableControlDrawCellDisplayText);
//Event Customization.
void gridGroupingControl1_TableControlDrawCellDisplayText(object sender, GridTableControlDrawCellDisplayTextEventArgs e)
{
GridTableCellStyleInfo style = e.Inner.Style as GridTableCellStyleInfo;
if (style.TableCellIdentity != null && style.TableCellIdentity.Column != null &&
style.TableCellIdentity.Column.Name == "Description" && e.Inner.RowIndex == 5)
{
Rectangle rectangle = e.Inner.ClipBounds;
rectangle.X -= 1;
rectangle.Y -= 1;
rectangle.Height += 3;
rectangle.Width += 2;
e.Inner.Graphics.FillRectangle(new SolidBrush(Color.LightBlue), rectangle);
}
}
VB
'Triggering the event. AddHandler gridGroupingControl1.TableControlDrawCellDisplayText, AddressOf gridGroupingControl1_TableControlDrawCellDisplayText 'Event Customization. Private Sub gridGroupingControl1_TableControlDrawCellDisplayText(ByVal sender As Object, ByVal e As GridTableControlDrawCellDisplayTextEventArgs) Dim style As GridTableCellStyleInfo = TryCast(e.Inner.Style, GridTableCellStyleInfo) If style.TableCellIdentity IsNot Nothing AndAlso style.TableCellIdentity.Column IsNot Nothing AndAlso style.TableCellIdentity.Column.Name = "Description" AndAlso e.Inner.RowIndex = 5 Then Dim rectangle As Rectangle = e.Inner.ClipBounds rectangle.X -= 1 rectangle.Y -= 1 rectangle.Height += 3 rectangle.Width += 2 e.Inner.Graphics.FillRectangle(New SolidBrush(Color.LightBlue), rectangle) End If End Sub
