How to set a filter condition explicitly in WinForms GridGroupingControl?

Filter condition

In WinForms GridGroupingControl, the filter conditions can be explicitly set by adding Record Filters. To add the record filters, you need to create a RecordFilterDescriptor.

// Filtering Condition.
FilterCondition condition = new FilterCondition(FilterCompareOperator.Like, "Australia");

// Add the Condition to the particular Column.
RecordFilterDescriptor rf = new RecordFilterDescriptor("WorkingBranch", condition);

// Add the RecordFilterDescriptor to the RecordFilters.
this.gridGroupingControl1.TableDescriptor.RecordFilters.Add(rf);

'Filtering Condition.
Dim condition As New FilterCondition(FilterCompareOperator.Like, "Australia")

'Add the Condition to the particular Column.
Dim rf As New RecordFilterDescriptor("WorkingBranch", condition)

'Add the RecordFilterDescriptor to the RecordFilters.
Me.gridGroupingControl1.TableDescriptor.RecordFilters.Add(rf)
