Custom filter row

[ninh]

hi
I want to filter row default is "Contains"
So should I do?

Hello ninh,

The filter operators are defined in each type of ColumnHeader. If you want to change the behavior of the filter cell for a text column, you need to find the TextColumnHeader control and the ApplicableFilterOperators property. You may either change the order they should appear or remove any of them that you think are unnecessary.

Thanks for the answer! But I do not really understand.

Hello ninh,

The example in our demos - Custom Filter Row - contains different UserControls - NumericColumnHeader, BooleanColumnHeader, TextColumnHeader,etc. In the code behind of the TextColumnHeader has a property ApplicableFilterOperators:

protected override IEnumerable<FilterOperator> ApplicableFilterOperators
       {
           get
           {
               return new FilterOperator[]
               {
                   FilterOperator.StartsWith,
                   FilterOperator.EndsWith,
                   FilterOperator.Contains,
                   FilterOperator.DoesNotContain,
                   FilterOperator.IsContainedIn
               };
           }
       }

You may remove those that you do not want to see or change their order.
However, you may also look at this example that filters only using Contains(in case of string values) or IsEqualTo (in case of numeric values) operators.

All the best,
