dataGrid RowDetails with several lines

06-29-2009 10:40 AM |

Hello,

Is this possible? To have several rows on a the RowDetails? I have a datagrid and I want to group several items below a certain row. I tried inserting a DataGrid in the row details but then in the .cs code I could access it to set the ItemsSource. 

I have the following code:

         <data:DataGrid x:Name="taxaPenDetails"
                           Background="Transparent"
                           Margin="30,47,30,65"
                           AutoGenerateColumns="False">

                <data:DataGrid.RowDetailsTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal"
                                    Background="Beige">

                        <data:DataGrid x:Name="innerGrid">

                    (...)

                 </data:DataGrid>

                    </StackPanel>
                    </DataTemplate>
                </data:DataGrid.RowDetailsTemplate>

                <data:DataGrid.Columns>

        (...)

        </data:DataGrid>

Thanks.

You could put a DataGrid in the RowDetails of another DataGrid.  If you do so, you should DataBind the inner DataGrid's ItemsSource to a collection on your entity.

However, instead of doing that for this scenario, you should take advantage of the new RowGrouping feature that's part of the Silverlight 3 DataGrid.

I put a DataGrid in the RowDetails of the other DataGrid but in the code behind I can't access it to set its Items Source. I thought the inner DataGrid would inherit the outer DataGrid's ItemsSource but apparently it doesn't :\ Is there any other solution or am I doing anything wrong?

I can't use Silverlight 3 just yet. Gotta wait until it's released..

Thanks.

Thanks for your answer, I'm still trying to do this.

I have another question. Is it possible to have a row not have RowDetails? My datagrid has its data bound from an external source (silverlight-enabled wcf service) and all the rows have the rowdetails (even when there's no data to show inside). Can I have a specific row to not have these details?

Cheers

You could bind the Visibility of what's in your row details template to something appropriate to have rows that have and don't have details.  You might need to use a ValueConverter as part of the Binding so you can Convert from say an empty collection to Visibility.Collapsed.
