Question

I’m trying to indent items on a WPF navBar. I can do this in XAML using resources and setting the visualstyle to the appropriate style

<dx:DXWindow.Resources>
    <Style x:Key="nestedNavBarItemL1" TargetType="ButtonBase">
        <Setter Property="Margin" Value="20,0,0,0"/>
    </Style>
    <Style x:Key="nestedNavBarItemL2" TargetType="ButtonBase">
        <Setter Property="Margin" Value="40,0,0,0"/>
    </Style>
</dx:DXWindow.Resources>

.
.
<dxnb:NavBarItem Content="Source Group"
       ImageSource="Images/Icons/Group.png" 
       VisualStyle="{StaticResource nestedNavBarItemL1}"/>
.
.

However, this is fine if the controls are already created but I’m building up the controls through code using something similar to

NavBarGroup group1 = new NavBarGroup();
group1.Header = eventItems[i].name;
group1.Tag = eventItems[i].id;

for (int i = 0; i < nodeCount; i++)
{
    NavBarItem item = new NavBarItem();
    item.Content = "Home";
    item.Tag = "Level" + i;
    //item.VisualStyle = ? How do I set VisualStyle="{StaticResource nestedNavBarItemL1}"/>
    group1.Items.Add(item);
}

group1.IsExpanded = false;
navBarControl.Groups.Add(group1);

How do I set VisualStyle="{StaticResource nestedNavBarItemL1}" in code?

Thank you,

If you already have style defined in resources, you could use FindResource method to get it and then assign to the relevant property like this (window is where resource defined):

Style visualStyle = (Style)window.FindResource("nestedNavBarItemL1");
item.VisualStyle = visualStyle;

If you don’t you can create it as shown in this codeproject article.
