Selection

To change the selected record’s text font, the QueryCellStylenfo event can be used. By default, GridGroupingControl have the two kinds of selections.

To change the selection back color when the selection is enabled by using AllowSelection property, AlphaBlendSelectionBackColor property of TableOptions can be used.

To change the selection back color when the selection is enabled by using ListBoxSelectionMode property, SelectionBackColor property of TableOptions can be used.

Using AllowSelection

C#

//Form()
//Triggering the event.
this.gridGroupingControl1.QueryCellStyleInfo += new GridTableCellStyleInfoEventHandler(gridGroupingControl1_QueryCellStyleInfo); 
 
this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.Row | GridSelectionFlags.AlphaBlend;
this.gridGroupingControl1.TableModel.Options.AlphaBlendSelectionColor = Color.Cyan;
 
//Handling the event.
void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
    int rowIndex = e.TableCellIdentity.RowIndex;
    if(e.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Record 
        &&  this.gridGroupingControl1.TableModel.SelectedRanges.Contains(GridRangeInfo.Row(rowIndex)))
    {
        e.Style.Font.Bold = true;
        e.Style.TextColor = Color.Blue;
    }
}

 

VB

'Form()
'Triggering the event.
Private Me.gridGroupingControl1.QueryCellStyleInfo += New GridTableCellStyleInfoEventHandler(AddressOf gridGroupingControl1_QueryCellStyleInfo)
 
'If AllowSelection property was used to enable the selection
Me.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.Row Or GridSelectionFlags.AlphaBlend
Me.gridGroupingControl1.TableModel.Options.AlphaBlendSelectionColor = Color.Cyan
 
'Handling the event.
Private Sub gridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As GridTableCellStyleInfoEventArgs)
 Dim rowIndex As Integer = e.TableCellIdentity.RowIndex
 If e.TableCellIdentity.DisplayElement.Kind Is DisplayElementKind.Record AndAlso Me.gridGroupingControl1.TableModel.SelectedRanges.Contains(GridRangeInfo.Row(rowIndex)) Then
  e.Style.Font.Bold = True
  e.Style.TextColor = Color.Blue
 End If
End Sub

 

Using ListBoxSelectionMode

C#

//Form()
//Triggering the event.
this.gridGroupingControl1.QueryCellStyleInfo += new GridTableCellStyleInfoEventHandler(gridGroupingControl1_QueryCellStyleInfo); 
this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.One;
this.gridGroupingControl1.TableOptions.SelectionBackColor = Color.Cyan; 
 
//Handling the event.
void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e) 
{ 
    if(e.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Record && e.TableCellIdentity.DisplayElement.GetRecord().IsSelected()) 
    { 
        e.Style.Font.Bold = true; 
        e.Style.TextColor = Color.Blue;
    } 
} 

 

VB

'Form()
'Triggering the event.
Private Me.gridGroupingControl1.QueryCellStyleInfo += New GridTableCellStyleInfoEventHandler(AddressOf gridGroupingControl1_QueryCellStyleInfo)
 
Me.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.One
Me.gridGroupingControl1.TableOptions.SelectionBackColor = Color.Cyan
 
'Handling the event.
Private Sub gridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As GridTableCellStyleInfoEventArgs)
 If e.TableCellIdentity.DisplayElement.Kind Is DisplayElementKind.Record AndAlso e.TableCellIdentity.DisplayElement.GetRecord().IsSelected() Then
  e.Style.Font.Bold = True
  e.Style.TextColor = Color.Blue
 End If
End Sub
