I recommend you to take a look at Crosslight FormBuilderSamples. Navigate to Editors > List View > Navigation section. The sample shows how to add ListView on FormBuilder.

I tried to run the sample on iPhone 6s iOS 9.2 (emulator) without any problem.

Please feel free to let me know if you find anything that I might miss during my attempt to reproduce the problem.

Sorry for the delay in sending this.

By comparing Firefox_correctly_shows.JPG and IE_11_wrap.JPG, I can see that the caption of column header overlapping the next column header in IE browser.

Try to add CustomRules in HeaderStyle and set its value as shown in the following snippet code.

<ISWebGrid:WebGrid ID="WebGrid1" runat="server" ...>
    <RootTable DataKeyField="CODICE">
        <Columns>
            <ISWebGrid:WebGridColumn Caption="CODICE" DataMember="CODICE"
                Name="CODICE" Width="100px">
            </ISWebGrid:WebGridColumn>
            ...
        </Columns>
    </RootTable>
    <LayoutSettings ...>
        ...
        <HeaderStyle ... CustomRules="text-overflow:ellipsis;overflow:hidden;" />
    </LayoutSettings>
</ISWebGrid:WebGrid>

This should helps.

Thank you for the sent sample.

I found WebForm1.aspx page in your sample. This page has WebGrid control inside. When view this page in browser, WebUI Framework (through Theme architecture) will detect for istheme.config file and automatically apply the contained theme information and component's style definition to the requested page.

As stated in winvista.istheme, the style definition for WebGrid component using DefaultSample.isl (see snippet code of winvista.istheme below).

<?xml version="1.0" encoding="utf-8"?>
<ISTheme>
  <ThemeGroup Name="Default" IsDefault="true">
    <ISComponents>
      <Component Type="ISNet.WebUI.WebDesktop.WebDesktopManager"
        Assembly="ISNet.WebUI.WebDesktop"LayoutName="Vista" DataFile="WinVista.isl" />
      <Component Type="ISNet.WebUI.WebGrid.WebGrid"
        Assembly="ISNet.WebUI.WebGrid" LayoutName="NewStyle" DataFile="DefaultSample.isl" />
    </ISComponents>
  </ThemeGroup>
</ISTheme>

Try to add this data file into WinVista folder. You can use the attached DefaultSample.isl file for test purpose. After that, ensure that you have granted write permission of the WinVista folder.

Save all the changes; build your web application; and view WebForm1.aspx page in browser. WinVista.css file will be generated at first run.

Note: I enclose the generated file, WinVista.css, for reference.

Please let me know if you have different result.

By enabling AutoPostBackSettings and specific action is executed (in this case: drag-drop, node add, node check changed, node delete, and node edit), WebTreeView will call specified event handler at server-side where developer can perform additional action based on that event.

Try to set PostBackModeType property to FlyPostBack to have advantages from both world. Event handler at server-side and client-side events are firing.

The changes can be seen in the following snippet code:

<ISWebTreeView:WebTreeView ID="WebTreeView2" runat="server"
    ...
    AllowAddNode="True" AllowDeleteNode="True" AllowNodeEditing="Yes"
    OnNodeSelectChanged="WebTreeView2_NodeSelectChanged"
    PostBackModeType="FlyPostBack">
    <AutoPostBackSettings OnDragDrop="true" OnNodeAdd="true"
        OnNodeMove="true" OnNodeSelectChanged="True" />
    <DragDropSettings AllowRootDrop="True" AllowChildDrop="True"
        AllowLeafDrop="True" AllowSiblingDrop="True" />
    <NodeSettings EnableAnimation="True" />
    <ClientSideEvents OnDragDrop="OnDragDrop" OnNodeMove="OnNodeMove"
        OnNodeAdd="OnNodeAdd" />
</ISWebTreeView:WebTreeView>

This should helps.

I created a simple sample of WebTreeView based on your description. The data source is a List and the treeview node is contructed on Page_Load event.

Following treeview events: Drag Drop, NodeMove, NodeAdd - are working as expected. Please have the attached sample evaluated on your end and let me know if you have different result.
