[Solved] Combining 2 specific rows

[Jasper]

Hi,

I have a RadGridView control which is filled with databinding. The source data contains 'datasets' which have the property "Type". These Types are unique for each dataset. The gridview looks like this:

<telerik:RadGridView Grid.Row="0" ItemsSource="{Binding DataSets}" SelectedItem="{Binding SelectedDataSet, Mode=TwoWay}" BorderThickness="0"
                             AutoGenerateColumns="False" IsReadOnly="True" ShowGroupPanel="False">
            <i:Interaction.Behaviors>
                <gri:RadGridViewFilterBehavior Expression="{Binding FilterExpression, Mode=TwoWay}">
                    <gri:RadGridViewFilterBehavior.FieldNameSupplier>
                        <filtering:DataSetFieldNameSuplier />
                    </gri:RadGridViewFilterBehavior.FieldNameSupplier>
                    <gri:RadGridViewFilterBehavior.TypeResolver>
                        <filtering:DataSetTypeResolver />
                    </gri:RadGridViewFilterBehavior.TypeResolver>
                </gri:RadGridViewFilterBehavior>

                <gri:RadGridViewSortBehavior Sort="{Binding SortExpression, Mode=TwoWay}">
                    <gri:RadGridViewSortBehavior.FieldNameSupplier>
                        <filtering:DataSetFieldNameSuplier />
                    </gri:RadGridViewSortBehavior.FieldNameSupplier>
                </gri:RadGridViewSortBehavior>
            </i:Interaction.Behaviors>

            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn ShowDistinctFilters="False" Header="{Binding Resource.Name, Source={StaticResource strings}}" DataMemberBinding="{Binding Name}" />
                <telerik:GridViewDataColumn ShowDistinctFilters="False" Header="{Binding Resource.Type, Source={StaticResource strings}}" DataMemberBinding="{Binding Type}" />
                <telerik:GridViewDataColumn ShowDistinctFilters="False" Header="{Binding Resource.Officer, Source={StaticResource strings}}" DataMemberBinding="{Binding Officer}" />
                <telerik:GridViewDataColumn ShowDistinctFilters="False" Header="{Binding Resource.StartDate, Source={StaticResource strings}}" DataMemberBinding="{Binding StartDate}" DataFormatString="dd-MM-yyyy" />
                <telerik:GridViewDataColumn ShowDistinctFilters="False" Header="{Binding Resource.EndDate, Source={StaticResource strings}}" DataMemberBinding="{Binding EndDate}" DataFormatString="dd-MM-yyyy" />
                <telerik:GridViewDataColumn ShowDistinctFilters="False" Header="{Binding Resource.CreationDate, Source={StaticResource strings}}" DataMemberBinding="{Binding CreationDate}" DataFormatString="dd-MM-yyyy hh:mm" />
                <telerik:GridViewDataColumn ShowDistinctFilters="False" Header="{Binding Resource.Description, Source={StaticResource strings}}" DataMemberBinding="{Binding Description}" />
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

I want to 'group' two specific rows, lets say with types Type2A & Type2B.
It should look like this:

• Type1
• Type2
• A
• B
• Type3

I looked at grouping for GridViews but this always seems to apply to all rows, not to just 2 specific rows.

My question:

Is it even possible to do this?
If so, how?

Hi,

The way to write your custom grouping expression would be to use a generic GroupDescriptor. You can try grouping the items as you would like to.
