ShowLineImages vs skin

[Al]

Hi,

I use the metro skin which seems to hide my treeview node lines by default. If I set ShowLIneImages="true" this doesn't have any effect so I what is the correct approach to get no lines with the Metro skin?

Sorry about the typo. "what is the correct approach to get node lines with the Metro skin?"

Hi Al,

The lightweight TreeView supports node lines also in the Metro skin. So to resolve the issue, simply set the render mode to lightweight.

When I use the code below then I get the node lines but the little expand /collapse indicator disappears

RenderMode="Lightweight"
ShowLineImages="true"

Hi Al,

Here is a very simple implementation of a RadTreeView in Lightweight render mode and Metro skin, with its lines shown:

<telerik:RadTreeView runat="server"
    RenderMode="Lightweight"
    ShowLineImages="true"
    Skin="Metro">
    <Nodes>
        <telerik:RadTreeNode Text="Node 1">
            <Nodes>
                <telerik:RadTreeNode Text="Node 1.1" />
                <telerik:RadTreeNode Text="Node 1.2" />
                <telerik:RadTreeNode Text="Node 1.3" />
            </Nodes>
        </telerik:RadTreeNode>
        <telerik:RadTreeNode Text="Node 2">
            <Nodes>
                <telerik:RadTreeNode Text="Node 2.1" />
                <telerik:RadTreeNode Text="Node 2.2" />
                <telerik:RadTreeNode Text="Node 2.3" />
            </Nodes>
        </telerik:RadTreeNode>
    </Nodes>
</telerik:RadTreeView>

On our side, the above renders correctly both lines and the expand / collapse arrow. Could you, please tell us how to modify the above, so it reproduces the problem observed?

Ok I eventually figured out why mine gave strange behaviour - I had two treeviews on my page, if one is set to lightweight and the other is not then the +/- arrows don't display as expected, set both to lightweight and all is ok.

Hi Al,

The Telerik AJAX controls suite supports only one type of render mode per page for each control type. Using different Render modes would lead appearance issues as the observed.
