Field name must be unique. How to deal with object composition?
posted
Hi,

 

The list binded here is à list of Contacts objects. A contact is composed of an object ContactName which is composed of 2 strings “First” and “Last”.

My problem is the field name must be unique. So, how can I do to display ContactName.Last and ContactName.First in two differents columns.

 

This doesn’t work too:  <igDP:Field Name="ContactName.First" Label="Last Name">


 

Here is my xaml code:

 

 

<Style TargetType="{x:Type igDP:CellValuePresenter}" x:Key="StyleTemplatePersonNameFirst">

    <Setter Property="Template">

        <Setter.Value>

            <ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">

                <Grid>

                    <TextBlock Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content.First}"/>                                                                       

                                </Grid >

            </ControlTemplate>

        </Setter.Value>

    </Setter>

</Style>

<Style TargetType="{x:Type igDP:CellValuePresenter}" x:Key="StyleTemplatePersonNameLast">

    <Setter Property="Template">

        <Setter.Value>

            <ControlTemplate TargetType="{x:Type igDP:CellValuePresenter}">

                <Grid  >

                    <TextBlock Text="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content.Last}"/>                                                                        

                                </Grid >

            </ControlTemplate>

        </Setter.Value>

    </Setter>

</Style>

 



 

<TabItem Name="TabItemAllXamDataGrid"  Header="_All (XamDataGrid)" >

    <igDP:XamDataGrid Name="xamDataGridAll" BindToSampleData="False"  DataSource="{Binding}" GotFocus="xamDataGridAll_GotFocus" >

 

        <igDP:XamDataGrid.FieldLayoutSettings>

            <igDP:FieldLayoutSettings AutoGenerateFields="False"  />

        </igDP:XamDataGrid.FieldLayoutSettings>

        <igDP:XamDataGrid.FieldLayouts>

            <igDP:FieldLayout>

 

                <igDP:Field Name="ContactName" Label="Last Name">

                    <igDP:Field.Settings>

                        <igDP:FieldSettings CellValuePresenterStyle="{StaticResource StyleTemplatePersonNameLast}" />

                    </igDP:Field.Settings>

                </igDP:Field>

 

 

!!! This doen’t work because field name must be unique !!!

                <igDP:Field Name=" ContactName " Label="First Name">

                    <igDP:Field.Settings>

                        <igDP:FieldSettings CellValuePresenterStyle="{StaticResource StyleTemplatePersonNameFirst}" />

                    </igDP:Field.Settings>

                </igDP:Field>

 

 

                </igDP:FieldLayout.Fields>

            </igDP:FieldLayout>

        </igDP:XamDataGrid.FieldLayouts>

 

    </igDP:XamDataGrid>
