ModelFragment (LSML file) where do I find documentation (or intellisense)

Question

I'm creating an extension control with the help of several examples scattered here and there on the web. But I can't seem to find any MSDN documentation for creating/modifying the LSML file..

Intellisense would also be very welcome :)

Answer 1

The only time you should need to look at the .lsml file is when you ae making Screen Templates (for example: Creating a Visual Studio LightSwitch Screen Template).

What kind of control are you making that you need to alter the .lsml file?

HI Michael,

I'm creating a DataGrid Control Extension bases on you're example ;). It will support ColumnHeader filtering (hopefully).

http://lightswitchhelpwebsite.com/Blog/tabid/61/EntryId/104/Creating-A-LightSwitch-Collection-Control-Extension.aspx

I've replaced the ChildView=":Summary" with ChildView=":DataGridRow" as I've seen in another example somewhere else. I'm interested in the how's and why's on this file, what kind of properties are supported.

<?xml version="1.0" encoding="utf-8" ?>
<ModelFragment
  xmlns="http://schemas.microsoft.com/LightSwitch/2010/xaml/model"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  
  <Control Name="SimpleDataGrid"
    SupportedContentItemKind="Collection"
    DesignerImageResource="SimpleDataGridExtension.SimpleDataGrid::ControlImage"
    AttachedLabelSupport="DisplayedByContainer"
    ChildView=":Summary">
    <Control.Attributes>
      <DisplayName Value="SimpleDataGrid" />
    </Control.Attributes>
  </Control>
</ModelFragment>

In my experience, the only reason you need the .lsml file is a screen template because a screen template requires you to reference controls using a special naming format. Looking in the .lsml file helps in that situation.

For all other controls, the end-user LightSwitch developer will bind a single property or collection to your control. Even the Many-To-Many control binds to a single collection.

That's it, that is all you have to work with. The .lsml file doesn't provide any help.
