Treemap margin
posted

Hello,

In your Drilldown sample you can see that the root level has a margin around. As we're going deeper, margin disappears. Is there any way to control that? I would like to set margin to 0 on all levels.

Thank you.

    Hello,

    When the xamTreemap control binds to data, it creates a root node which will contain the nodes from the data source - the margin you are seeing belongs to that root node. In the sample when a drilldown is performed, the root node is changed with a styled node - that's why the margin disappears.

    You can set a style for the default root node through the DefaultStyle property of the xamTreemap control.

    Here is a sample style:

     

                <ig:XamTreemap.DefaultStyle>
                <Style TargetType="ig:TreemapNode">
                    <Setter Property="Padding" Value="0" />
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="ig:TreemapNode">
                                <ig:NodesPanel x:Name="NodesPanel" />
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </ig:XamTreemap.DefaultStyle>

    Thanks, Nikolay
