What if I want to define the Template of the child nodes?

I mean, I need to define the node of 2 levels withot modify the dataTemplate, I add the child nodes programmatically... and that work fine but I need to add other icon to those new nodes in the second level...

I use this code to define the first level template but I cant modify the expandedicontemplate for the child nodes...

<code>

<

UserControl.Resources>

<DataTemplate x:Key="DriveCollapsedIcon">

<Grid>

<Image Source="/Via.SaaS.FrontEnd;Component/Images/Drive.png" Height="17" Width="17" />

</Grid>

</DataTemplate>

<DataTemplate x:Key="DirectoryExpandedIcon">

<Grid>

<Image Source="/Via.SaaS.FrontEnd;Component/Images/OpenFolder.png" Height="20" Width="20" />

</Grid>

</DataTemplate>

<DataTemplate x:Key="DirectoryCollapsedIcon">

<Grid>

<Image Source="/Via.SaaS.FrontEnd;Component/Images/CloseFolder.png" Height="15" Width="15" />

</Grid>

</DataTemplate>

</UserControl.Resources>

<Grid x:Name="LayoutRoot">

<igTree:XamWebTree x:Name="test" HorizontalAlignment="Left" Margin="21,22,0,56" Width="222" ExpandedIconTemplate="{StaticResource DirectoryExpandedIcon}" CollapsedIconTemplate="{StaticResource DirectoryCollapsedIcon

}" >

</igTree:XamWebTree>

</code>

I've tried two ways of doing this. Im sure its something simple. The sample you sent above I couldnt use exactly as I received an error upon binding.

        <igTree:XamWebTree x:Name="dataTree" Background="Transparent" BorderThickness="1,1,1,1" HorizontalAlignment="Stretch" IsCheckBoxThreeState="True" CheckBoxVisibility="Visible">
            <igTree:XamWebTree.HierarchicalItemTemplate>
                <ig:HierarchicalDataTemplate ItemsSource="{Binding Children}">
                    <DataTemplate>
                        <TextBlock Text="{Binding Name}" />
                    </DataTemplate>
                    <ig:HierarchicalDataTemplate.ItemTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Name}" />
                        </DataTemplate>
                    </ig:HierarchicalDataTemplate.ItemTemplate>
                    <ig:HierarchicalDataTemplate.DefaultItemsContainer>
                        <DataTemplate>
                            <igTree:XamWebTreeItem CollapsedIcon="{Binding CollapsedIcon}" ExpandedIcon="{Binding ExpandedIcon}"/>
                        </DataTemplate>
                    </ig:HierarchicalDataTemplate.DefaultItemsContainer>
                </ig:HierarchicalDataTemplate>

            </igTree:XamWebTree.HierarchicalItemTemplate>
        </igTree:XamWebTree>

 public class MyDataFromXML
        {
            public string Name { get; set; }
            public BitmapImage CollapsedIcon { get; set; }
            public BitmapImage ExpandedIcon { get; set; }
            public IEnumerable<MyDataFromXML> Children { get; set; }
        }

for the binding code I tried this way:

            List<MyDataFromXML> folderItems = new List<MyDataFromXML>();
            folderItems.Add(new MyDataFromXML() { Name = "somefile.txt" });

            MyDataFromXML folder1 = new MyDataFromXML();
            folder1.Name = "folder1";

            MyDataFromXML subFolder = new MyDataFromXML();
            subFolder.Name = "subfolder";
            List<MyDataFromXML> subFolderItems = new List<MyDataFromXML>() { new MyDataFromXML() { Name = "subfolderfile.txt" } };

            folder1.Children = new List<MyDataFromXML>() { subFolder };
            subFolder.Children = subFolderItems;
           
            folderItems.Add(subFolder);

            //format should be:
            //folder1
            //  somefile.txt
            //  subfolder
            //    subfolderfile.txt

            this.dataTree.ItemsSource = new List<MyDataFromXML> { folder1 };
            this.dataTree.XamWebTreeItems[0].IsExpanded = true;

as well as this way:

            XDocument doc = XDocument.Load(xmlFile);
            var dataSource = (from d in doc.Descendants("folder")
                              select new MyDataFromXML
                              {
                                  Name = d.Attribute("name") == null ? "" : d.Attribute("name").Value,
                                  Children = this.GetItems(d)
                              });

            this.dataTree.ItemsSource = dataSource.ToList();
            this.dataTree.XamWebTreeItems[0].IsExpanded = true;

//This is using the same xml as posted above although I changed all 'title' to 'name'

//I've tried variations on this getting folder/file elements. I may just be visualizing this incorrectly based on required layout.

        private IEnumerable<MyDataFromXML> GetItems(XElement parent)
        {

            var items = (from d in parent.Descendants()
                       select new MyDataFromXML
                       {
                           Name = d.Attribute("name") == null ? "" : d.Attribute("name").Value,
                           Children = this.GetItems(d)
                       });
            return items;
        }

Hi,

Could you post the code which is for your data object class and the collection which you use as a data source?

Also, the code which assigns the data source to the tree and the template you apply?

Thanks,

thanks for the reply. It is still a bit off.. using that template with this data:

<?xml version="1.0" encoding="utf-8" ?>
<fileSystem>
  <folder name="c:\">
    <file name="file1.txt" />
    <file name="file2.txt" />
    <folder name="windows">
      <file name="sub item 1" />
      <file name="sub item 2" />
      <file name="sub item 3" />
      <file name="sub item 4" />
    </folder>
  </folder>

  <folder name="d:\">
    <file name="file10.txt" />
    <file name="file11.txt" />
    <file name="file12.txt" />
    <folder name="program files">
      <file name="program1" />
      <file name="program2" />
    </folder>
  </folder>
</fileSystem>

I receive a tree that looks like: (note items with * are incorrect)

c:\
   file1.txt
   file2.txt
   sub item 1 (*)
   sub item 2 (*)
   sub item 3 (*)
   sub item 4 (*)
windows
   sub items 1-4
d:\
   file10.txt
   file11.txt
   file12.txt
   program1 (*)
   program2 (*)

program files
   program1
   program2

so it folds up the subfolders into the current folder IE doesnt show the folder windows under c:\
