A standard way to cancel filtering is to left-click filter icon while holding Shift.

The Dapfor.Wpf.dll library includes a set of predefined filters collected in Filters.FilterFactory:

Wpf GridControl CheckBoxFilter

Wpf GridControl ValueListFilter


The filter displays a lits of values discovered in grid cells in the specified column. Users can choose a value from the proposed list. To cancel filtering you can click a crossed filter icon in the upper left corner or choose <All>.

Wpf GridControl ComparableValueFilter


You can use this filter for all types implementing the IComparable interface. This includes all whole number types (Int32, Byte, ...), with floating comma (Double, Decimal), dates DateTime, TimeSpan, strings (String) and many others.

Wpf GridControl WildcardFilter


The filter uses regular expression for row filtering. If the filter does not use wildcards, the following pattern is applied by default: *<filter>*

Wpf GridControl DateMultiFilter


You can use it to filter rows by set dates. You can set multiple conditions.

You can set filters for a column directly in xaml code:

<Window x:Class="SomeApplication.MainWindow"

                    <my:Column Id="Status" Title="Status" FilterTemplate="{x:Static filters:FilterFactory.CheckBoxFilter}" FilterAlignment="Stretch"/>
                    <my:Column Id="Established" Title="Established" FilterTemplate="{x:Static filters:FilterFactory.DateMultiFilter}"/>

You can also set filters programmatically as shown below:

Column column = gridControl1.Headers[0]["Established"];
column.FilterTemplate = FilterFactory.WildcardFilter;

Developers can create their own filters in addition to predefined filters. This feature is implemented in the grid with DataTemplate
