Use the FilterMode property to specify how the component displays filtered nodes. The example below sets the property value to ParentBranch:

<DxTreeView ShowFilterPanel="true"
            FilterMode="NavigationFilterMode.ParentBranch">
  @* ... *@
</DxTreeView>

In the following example, the FilterMode property value is set to EntireBranch:

<DxTreeView ShowFilterPanel="true"
            FilterMode="NavigationFilterMode.EntireBranch">
  @* ... *@
</DxTreeView>

            FilterMode="NavigationFilterMode.Nodes">
  @* ... *@
</DxTreeView>
