    Hello James,

    All you need to do in order to set the height of RadTreeView items is:

    1.Add appropriate style in the resources:

    <UserControl.Resources>
            <Style TargetType="telerik:RadTreeViewItem" x:Key="TreeViewItemStyle">
                <Setter Property="MinHeight" Value="250"></Setter>
            </Style>
        </UserControl.Resources>

    2. Set ItemContainerStyle property of the RadTreeView:

    <telerik:RadTreeView ItemContainerStyle="{StaticResource TreeViewItemStyle}" .../>

    I hope that this answers your question.

    Hello 

    I've tried the suggested solution but the MinHeight property that is changing is in the RadTreeViewItem
    which I believe is not the desired one. As a result the tree height is reduced to the x value of the property
    and all child nodes are not visible any more.

    Instead I would like to change the height of the Grid named: HeaderRow (as shown in the xap file)
    inside  RadTreeViewItem for every node in the tree. Is this possible?

    Thanks

    Hello Andreas,

    The default Height of the RadTreeViewItem is 24. I prepared a sample for you that changes it to 15 using the approach suggested by Boryana. Could you please give it a try and let us know if this is what you expect? You can also elaborate more on your case so that we could advice you better.
    Thank you in advance for your cooperation.

    Kind regards,

    Thank you! The example project is very clear and solved my problem.
    Can you also please advice me how to reduce the tab space
    when expanding a tree node (IndentContainer's width)?

    Thanks

    Hi Andreas,

    You can use the ItemsIdent property of the RadTreeView like so:
    <telerik:RadTreeView x:Name="tree"
                                 Width="300"
                                 ItemsIndent="10"
                                 ItemContainerStyle="{StaticResource TreeViewItemStyle}"
                                >
    Let us know if you need further assistance.

    All the best,
