Raise Filtered event on custom filtering

[Victor]

Hello everyone, first of all, excuse me for my broken english.

I've developed a custom filters for DateTime and Time columns of my RadGridView.

Filters work great, but once I finish filtering I need to raise the Filtered event of grid, so the ViewModel will communicate with my RIA service sending all grid filter descriptors.

How do I raise programmatically the Filtered event?

Thanks in advance.

PS- I hope you understand what I'm trying to explain. If not, do not hesitate to ask me.

Nobody knows how to fire the Filtered event?

The grid is filtering, but the event is not firing...any idea?

Thanks in advance.

Hello,

The Filtered event is an UI event. It will only be raised on a user interaction.

Another way to encounter that a filtering has been performed would be to subscribe for the CollectionChanged event of the FilterDescriptors collection.

Once you have this code:

 

public void Prepare( Telerik.Windows.Controls.GridViewColumn column ) {

    _column = column as GridViewBoundColumnBase;
    _gridView = column.Parent as RadGridView;
    if( _column == null ) {

        return;
    }
}

 

You have to call in your function that applies the filter:

 

private void applyCheckboxFilter( CheckBox cb, int value ) {

    Telerik.Windows.Controls.GridView.IColumnFilterDescriptor okActionFilter;
    okActionFilter = _column.ColumnFilterDescriptor;
    _filterDescriptors.Clear();
    _filterDescriptors.Add( okActionFilter );

    if( cb.IsChecked == true ) {

        okActionFilter.DistinctFilter.AddDistinctValue( value );
    } else if( cb.IsChecked == false ) {

        okActionFilter.DistinctFilter.RemoveDistinctValue( value );
    }

    IsActive = okActionFilter.DistinctFilter.FilterDescriptors.Count() > 0;

    _gridView.RaiseEvent( new GridViewFilteredEventArgs( _filterDescriptors, null ) );
}

 

The last line is what you want.
