Is there a way to select complete row in TreeViewAdv? 

[Vijayalakshmi Roopkumar]

Hi Anup

Thank you for contacting the Syncfusion Support.

We have checked your requirement and it seems that you are asking about the MultiColumnTreeView. If so, you can able to select the Item on clicking the TreeviewItem. We have prepared the simple sample for the same, please download it from following location:

Sample: http://www.syncfusion.com/downloads/support/forum/136154/ze/Multicolumntreeview670011652.zip 

If our understanding on your requirement is different, please brief about your requirement clearly. It would be helpful for us to proceed on this.

Thanks for reply! No, I am not asking about MultiColumnTreeView. Please look at following XAML :
 

            <syncfusion:TreeViewAdv ItemsSource="{Binding Tasks}" >

                 <syncfusion:TreeViewAdv.ItemContainerStyle>

                    <Style TargetType="{x:Type syncfusion:TreeViewItemAdv}">

                        <Setter Property="IsExpanded" Value="True"/>

                    </Style>

                </syncfusion:TreeViewAdv.ItemContainerStyle>

                <syncfusion:TreeViewAdv.ItemTemplate>

                    <HierarchicalDataTemplate ItemsSource="{Binding SubTasks}">

                        <TextBlock Grid.Column="0" Text="{Binding Path=Name, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />

                    </HierarchicalDataTemplate>

                </syncfusion:TreeViewAdv.ItemTemplate>

            </syncfusion:TreeViewAdv>

Hi Anup,

Thank you for the information.

We have prepared a sample that tries to meet your requirement. In our sample, we have override the template of TreeviewAdv by binding TreeviewItemAdv ActualWidth to the border named "BD".

You can download the sample from below location:

Sample: http://www.syncfusion.com/downloads/support/forum/136154/ze/TreeViewAdv_Fullrowselect-2020554806 

Please try this solution and let us know if it is helpful.

I have looked at your sample, but there are issues with it 

1. Vertical Scroll is not working.

2.  It slowdown the selection (By looking at following style ,its try to find relative tree item to set Width),   

<Setter Property="Width" TargetName="Bd" Value="{Binding Path=ActualWidth, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type syncfusion:TreeViewItemAdv}}}" />

FYI : In my codebase, I have modified control template, now tree item takes full width, selection is superfast and scroll is working fine. 

Thanks

Anup

Hi Anup,

From your update, you have said that you have modified the template which works in your application. Can you share the template with us?
