How to Apply Conditional Formats Cell in WinForms GridGroupingControl?
Conditional formatting
By default,
the conditional format will be set to the entire row. In order to set the ConditionalFormatting for
a particular cell at run time, GridConditionalFormatDescriptor and QueryCellInfo event
can be used. In QueryCellInfo event, the CompareRecord method
can be used to compare the records with condition.
C#
GridConditionalFormatDescriptor descriptor = new GridConditionalFormatDescriptor();
//To add the condition
descriptor.Expression = "[CategoryID]>50";
gridGroupingControl1.TableDescriptor.ConditionalFormats.Add(descriptor);
//Event Triggering
this.gridGroupingControl1.QueryCellStyleInfo += GridGroupingControl1_QueryCellStyleInfo;
//Event Customization
private void GridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if (e.TableCellIdentity.Column != null && e.TableCellIdentity.Column.Name == "Description" && e.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Record)
{
Record record = e.TableCellIdentity.DisplayElement.GetRecord();
if (descriptor.CompareRecord(record))
{
e.Style.BackColor = Color.Yellow;
}
}
} VB
Private descriptor As New GridConditionalFormatDescriptor()
'To add the condition
descriptor.Expression = "[CategoryID]>50"
gridGroupingControl1.TableDescriptor.ConditionalFormats.Add(descriptor)
'Event Triggering
AddHandler Me.gridGroupingControl1.QueryCellStyleInfo, AddressOf GridGroupingControl1_QueryCellStyleInfo
'Event Customization
Private Sub GridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As GridTableCellStyleInfoEventArgs)
If e.TableCellIdentity.Column IsNot Nothing AndAlso e.TableCellIdentity.Column.Name = "Description" AndAlso e.TableCellIdentity.DisplayElement.Kind = DisplayElementKind.Record Then
Dim record As Record = e.TableCellIdentity.DisplayElement.GetRecord()
If descriptor.CompareRecord(record) Then
e.Style.BackColor = Color.Yellow
End If
End If
End Sub The screenshot below illustrates the conditional formatting in GridGroupingControl.
