Hi,

I'm trying to customize my DataGrid display depending on the data it contains.

What I need to have is:

   1) Changing the colour of some DataRows depending on a property of the displayed object (in order to highlight the active DataRows)

   2) Displaying some entire DataRows with strikethrough text depending on a property of the displayed object (in order to highlight invalid data)

   3) Having a custom display for some columns depending on the data stored in the cell (in order to display information easier to understand)

What I am using right now is:

   1) A Style applied on DataRow objects to change the colour of the line

   2) A Style applied on DataCell objects that modify the ControlTemplate in order to use a TextBlock with the TextDecorations set to Strikethrough

   3) A DataTemplate applied on a Column that uses a ContentPresenter using a Converter that modifies the data displayed (in order to replace the value "-1" by the text "Infinity" for example)

My problem is that when I try to use my second Style that modify the ControlTemplate, the DataTemplate/Converter is not applied. 

My questions are:

   1) How can I apply my Styles and my DataTemplate at the same time ? 

    2) Is there another way to achieve what I want ?

Thanks a lot. 

check out my post on this thread where I used DataTemplateSelector to choose the template based on the value in a column

I also have different CellEditor for different types of data in this thread

Also I believe there is something like ItemContainerStyleSelector which does the styles but I am not sure on that

Hope it helps

I think your code will be helpful on the next step for me, that is to say selecting the correct DataTemplate depending on a property of my data.

What bothers me now is mixing the DataTemplate I had set to my column's CellContentTemplate and the ControlTemplate used in my DataCell's Style.

I think I can solve my problem using a TemplateBinding, but I can't figure out how...

Here is what I have done for now:

   1) My DataTemplate:

        <conv:RelativeAbsoluteTimeConverter_C x:Key="relativeTimeConverter" />

        <DataTemplate x:Key="relativeTimeCellDataTemplate"

                      x:Name="relativeTimeCellDataTemplate">

            <ContentPresenter Content="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type xcdg:Cell}}, 

                Path=DataContext, 

                Mode=TwoWay, 

                Converter={StaticResource relativeTimeConverter},

                ConverterParameter={StaticResource dataSourceBus}}" />

        </DataTemplate> 

   2) My Column definition:

                <xcdg:DataGridControl.Columns>

                    <xcdg:Column FieldName="Time"

                                 Title="Time (µs)"

                                 ReadOnly="True"

                                 CellContentTemplate="{StaticResource relativeTimeCellDataTemplate}"/> 

   3) The Style used on my cells:

    <Style TargetType="xcdg:DataCell"

           BasedOn="{StaticResource DefaultDataCellStyle}"

           x:Key="DataCellTextBlockStyle">

        <Setter Property="Template">

            <Setter.Value>

                <ControlTemplate TargetType="xcdg:DataCell">

                    <TextBlock VerticalAlignment="Center"> 

                        <!-- Here is my problem ! I don't know how to get the Column's CellContentTemplate... --> 

                        <ContentPresenter ContentTemplate="{TemplateBinding ContentTemplate}" />

                        <!--<ContentPresenter ContentTemplate="{TemplateBinding xcdg:Column.CellContentTemplate}"/>-->

                        <!--<ContentPresenter ContentTemplate="{TemplateBinding ContentControl.ContentTemplate}" />-->

                        <!--<ContentPresenter ContentTemplate="{TemplateBinding xcdg:DataCell.ParentColumn.CellContentTemplate}" />-->

                    </TextBlock>

                    <ControlTemplate.Resources>

                        <Style TargetType="{x:Type TextBlock}">

                            <Style.Triggers>

                                <DataTrigger Binding="{Binding Path=IsValid}"

                                             Value="False">

                                    <Setter Property="Foreground"

                                            Value="Red" />

                                    <Setter Property="TextDecorations">

                                        <Setter.Value>

                                            <TextDecorationCollection>

                                                <TextDecoration Location="Strikethrough"

                                                                PenOffset="0.75" />

                                            </TextDecorationCollection>

                                        </Setter.Value>

                                    </Setter>

                                </DataTrigger>

                            </Style.Triggers>

                        </Style>

                    </ControlTemplate.Resources>

                </ControlTemplate>

            </Setter.Value>

        </Setter>

    </Style> 

If anyone has an idea on how to link my ContentPresenter ContentTemplate on my DataTemplate, that would be great.
