Q1 2012
NOTE!!!
Filtering BREAKING CHANGES !!!
NOTE!!!
In order to enable filtering for our GridViewExpressionColumn, we had to rewrite our entire filtering infrastructure from scratch. We have made as few breaking changes as possible, but some of them were inevitable, for which we would like to apologize. Here is the list of breaking changes that you should be aware of. Do not hesitate to write us if you are having problems with upgrading your project. We will do our best to assist you.
The IFilteringControl.Prepare method now expects the more general type GridViewColumn instead of a GridViewBoundColumnBase as its argument. If you were relying on GridViewBoundColumnBase-specific methods or properties you will have to add a check and a cast.
The GridViewDistinctValuesLoadingEventArgs.Column property is now of the more general type GridViewColumn. If you were relying on GridViewBoundColumnBase-specific methods or properties you will have to add a check and a cast in your DistinctValuesLoading event handler.
The GridViewDataControl.GetDistinctValues family of methods now accept a GridViewColumn instead of an IDataFieldDescriptor as their first parameter.
The EditorCreatedEventArgs.Column is now of the more general type GridViewColumn. If you were relying on GridViewBoundColumnBase-specific methods or properties you will have to add a check and a cast in your DistinctValuesLoading event handler.
The FilterOperatorsLoadingEventArgs.Column property is now of type GridViewColumn instead of IDataFieldDescriptor.
The ColumnFilterDescriptor class has been made internal. Use the IColumnFilterDescriptor interface instead. It contains all relevant properties and methods.
You can't directly instantiate a ColumnFilterDescriptor anymore since the class has been made internal. When you access the GridViewColumn.ColumnFilterDescriptor property, it will be automatically created on demand by the column and you will be given an IColumnFilterDescriptor to work with. For example: IColumnFilterDescriptor cfd = myColumnInstance.ColumnFilterDescriptor;
The IColumnFilterDescriptor.Column property is now of type GridViewColumn instead of IDataFieldDescriptor.
The IColumnFilterDescriptor.DistinctFilter property is now of type IDistinctValuesFilterDescriptor instead of DistinctValuesFilterDescriptor.
The IColumnFilterDescriptor.FieldFilter property is now of type IFieldFilterDescriptor instead of FieldFilterDescriptor.
The DistinctValuesFilterDescriptor class has been made internal. It is not supposed to be used directly from your code. Use the IDistinctValuesFilterDescriptor interface instead.
The FieldFilterDescriptor class has been made internal. It is not supposed to be used directly from your code. Use the IFieldFilterDescriptor interface instead.
If you were using code from the GridViewCustomSerialization PersistenceFramework example, please update it according to the updated example.
The GridViewDataControl.OnFiltering method is marked as obsolete now. It is not supposed to be used directly from your code and will be made internal in a future realease.
The GridViewDataControl.OnFiltered method is marked as obsolete now. It is not supposed to be used directly from your code and will be made internal in a future realease.
Some code changes are needed after the upgrade. Find the list with code snippets below.
- Filtering a Column____Before:
GridViewColumn ageColumn = this.radGridView.Columns["Age"];
ColumnFilterDescriptor ageColumnFilter = new ColumnFilterDescriptor(ageColumn);
// ...
ageColumnFilter.DistinctFilter.DistinctValues.Add(5);
ageColumnFilter.FieldFilter.Filter1.Operator = FilterOperator.IsLessThan;
ageColumnFilter.FieldFilter.Filter1.Value = 10;
// ...
this.radGridView.FilterDescriptors.Add(ageColumnFilter);
Dim ageColumn As GridViewColumn = Me.radGridView.Columns("Age")
Dim ageColumnFilter As New ColumnFilterDescriptor(ageColumn)
' ...
ageColumnFilter.DistinctFilter.DistinctValues.Add(5)
ageColumnFilter.FieldFilter.Filter1.[Operator] = FilterOperator.IsLessThan
ageColumnFilter.FieldFilter.Filter1.Value = 10
' ...
Me.radGridView.FilterDescriptors.Add(ageColumnFilter)
After:
- Clearing a Column Filter____Before:
- Clearing All RadGridView Filters____Before:
this.radGridView.FilterDescriptors.Clear();
After:
this.radGridView.FilterDescriptors.SuspendNotifications();
foreach (var column in this.radGridView.Columns)
{
column.ClearFilters();
}
this.radGridView.FilterDescriptors.ResumeNotifications();
Me.radGridView.FilterDescriptors.SuspendNotifications()
For Each column As var In Me.radGridView.Columns
column.ClearFilters()
Next
Me.radGridView.FilterDescriptors.ResumeNotifications()
End Class
