Changing Cell Template in a ListView programatically

Question

Hi all,

I´m working on an app. that uses TemplateResources to switch between differents ListViews according some conditions.
And, due the string that appears in one of the cells of the selected listView, i have to change the cell template from this:

<GridViewColumn >
                        <GridViewColumnHeader Content="Line Status" Tag="ReturnStatus.return_status_desc" Width="AUTO"/>
                            <GridViewColumn.CellTemplate>
                               <DataTemplate>
                                   <Label Name="lineStatusLbl" Content="{Binding Path=ReturnStatus.return_status_desc}"/>
                               </DataTemplate>
                        </GridViewColumn.CellTemplate>
</GridViewColumn>

To a Link:
<GridViewColumn>
                        <GridViewColumnHeader Content="Line Status" Tag="ReturnStatus.return_status_desc" Width="AUTO" />
                        <GridViewColumn.CellTemplate>
                            <DataTemplate x:Key="sarasa">
                <TextBlock VerticalAlignment="Center" HorizontalAlignment="Left" Margin="0 15 0 15" Style="{StaticResource LinkButtonContainerStyle}">
                    <Hyperlink Name="lnkErrorsWarnings" Style="{StaticResource LinkButtonStyle}" IsEnabled="True">
                        <TextBlock Name="errorsWarningsText"
                                   Style="{StaticResource LinkButtonContainerStyle}"
                                   HorizontalAlignment="Left"
                                   VerticalAlignment="Center"                              
                                   Text="{Binding Path=ReturnStatus.return_status_desc}">
                        </TextBlock>
                    </Hyperlink>  
                </TextBlock>
            </DataTemplate>
                        </GridViewColumn.CellTemplate>
</GridViewColumn>

Does anyone have any idea how to do it?

Answer 1

Hello,

Use a DataTemplateSelector:

<GridViewColumn CellTemplateSelector="{DynamicResource YourTemplateSelector}"/>

Yes, i finally found how to do it. I let my solution here, in case someone need to do something similar: First, i add two DataTemplates inside my grid_dataTemplate (Inside ListView.Resources): then, i create my TemplateSelector: public class LineStatusTemplateSelector : DataTemplateSelector { public DataTemplate TextTemplate { get; set; } public DataTemplate LinkTemplate { get; set; } public override DataTemplate SelectTemplate(object item, DependencyObject container) { if (item != null && item is SevPetroleumLine) { SevPetroleumLine returnStatusDesc = item as SevPetroleumLine; if (returnStatusDesc.ReturnStatus.return_status_desc.StartsWith("Ready")) { return TextTemplate; } else { return LinkTemplate; } } return null; } } the, i go back to griddatatemplate, add reference to TemplateSelector and add this line into ListView.Resources: and finally, use it in my column: =)
