Re: FilterRow incorrectly highlights/selects filter criterion when inside a DetailConfiguration

Hi Christopher,

The behavior cannot be overridden. The reason is because of the destruction and recreation of the Detail.

Is there a way to override to the FilterRow and/or FilterCell template so that this behavior can be avoided?

Hi Christopher,

The FilterRow on the DetailGrid and on the DataGrid itself do behave similarly except for that when the user is finished typing that it would select the whole text. When this feature was created, the concept of the Detail was that when the user would finish typing, it would destroy the DetailGrid that was there and recreate it. Unfortunately there are no plans in the foreseeable future. A request has been submitted to the team that is in charge of updating the documentation to correctly describe how the FilterRow behaves.

Notice the two images from the Master/Detail sample. In the before image, the cursor is visible in the filter row/cell. As I begin to type 'an' the rows become filtered accordingly. However shortly afterwards the 'an' becomes highlighted/selected. See the After image. Therefore as I continue to type, the 'an' gets replaced with the new text and so on.

FilterRow incorrectly highlights/selects filter criterion when inside a DetailConfiguration

I am having a problem when I add a FilterRow to the DetailConfiguration headers. When applied to a DataGridControl.View.FixedHeader, the criteria entered in the FilterRow automatically filters the results. The more criteria entered, the more the results are filtered. However when the same DataTemplate is applied to a DetailConfiguration.Headers element, the criteria works until you pause typing. After the pause, the results are filtered but the criteria becomes highlighted/selected. If the user continues typing, the old criteria is remove/replaced. This is causing some confusion with the users.

The documentation listed here in the Filtering Details Group states: "In addition to filtering the data items in a grid, a filter row can also be added to the headers or footers of a detail configuration" and 'Filter rows that are contained in the headers or footers of a group behave in the same manner as those contained in the headers or footers of a grid". This apparently is not the case. Please advise.

The problem can be easily reproduced by adding the following code to the SubEmployeesDetailConfigurations.xaml in the MasterDetail sample. Then slowly using the FilterRow to filter on the Sub Employee Last Name.

        <xcdg:DetailConfiguration.Headers>
            <DataTemplate>
                <Border Height="22">
                    <xcdg:FilterRow Height="22"
                                    SelectionBackground="LightGray"
                                    BorderBrush="Black"
                                    BorderThickness="1">
                    </xcdg:FilterRow>
                </Border>
            </DataTemplate>
        </xcdg:DetailConfiguration.Headers>
