    Does anyone know how to round the corners of Lightswitch buttons?  By buttons, I mean the regular buttons in a screen, not the command bar buttons on the ribbon control nor the buttons in a Datagrid.  I believe the normal way would be to create a theme containing a implicit style for TargetType="Button" and a ControlTemplate with an outer Border using CornerRadius. I tried that with a style for Button in Jan Van Der Haegen's ExtensionsMadeEasy. I also tried it using my own theme extension. But neither will actually change the style for the buttons in a Lightswitch project--I still get the same ole standard rectangular Lightswitch buttons.

    Finally, I tried creating my own button control extension and, of course, I can certainly set a specific style for it, but I would like it to use the selected Lightswitch theme for brushes, but I can't figure out how to reference a dynamic theme's resource dictionary either.

    Can anyone point me in the right direction?  Any idears would be greatly appreciated.

    I finally figured out how to get my Lightswitch button corners rounded.  With a little prompting from Derek Spurlock (if you don't already have the Spursoft Lightswitch Extensions, go get them!), I discovered that if you want to provide style resources beyond colors and fonts, you must have a class that implements IThemeExtension.

    If you follow Microsoft's Walkthrough: Creating a Theme Extension, you will find that you start with a theme XAML file that contains the fonts and color resources for your theme.  You will also find a theme class implementing ITheme that looks something like this:

    Imports System
    Imports System.ComponentModel.Composition
     
    Imports Microsoft.LightSwitch.Theming
     
    Namespace Presentation.Themes
     
        <Export(GetType(ITheme))>
        <Theme(MyTheme.ThemeId, MyTheme.ThemeVersion)>
        Friend Class MyTheme
            Implements ITheme
     
    #Region "ITheme Members"
     
            Public ReadOnly Property ColorAndFontScheme As Uri Implements ITheme.ColorAndFontScheme
                Get
                    Return New Uri("/MyThemeExtension.Client;component/Presentation/Themes/MyTheme.xaml", UriKind.Relative)
                End Get
            End Property
     
            Public ReadOnly Property Id As String Implements ITheme.Id
                Get
                Return MyTheme.ThemeId
                End Get
            End Property
     
            Public ReadOnly Property Version As String Implements ITheme.Version
                Get
                Return MyTheme.ThemeVersion
                End Get
            End Property
     
    #End Region
     
    #Region "Constants"
     
            Friend Const ThemeId As String = "MyThemeExtension:MyTheme"
            Friend Const ThemeVersion As String = "1.0"
     
    #End Region
     
        End Class
     
    End Namespace

    You can then add a very basic button style with rounded corners to the bottom of your theme xaml file:

    <Style TargetType="Button" x:Key="DefaultButtonStyle">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="ButtonBorder"
                           CornerRadius="4"
                           BorderBrush="{StaticResource ButtonBorderBrush}"
                           Background="{StaticResource ButtonBackgroundBrush}">
                        <ContentPresenter Content="{TemplateBinding Content}"
                                                  HorizontalAlignment="Center"
                                                  VerticalAlignment="Center"/>
                    < /Border>
                < /ControlTemplate>
            < /Setter.Value>
        < /Setter>
    < /Style>
     
    <Style TargetType="Button" BasedOn="{StaticResource DefaultButtonStyle}" />


    But if you run and test your extension now, the buttons in your test application will be unaffected by your added style.  To have your style used, you must add a new class to your theme_extension.client project that implements IThemeExtension:

    Imports System.ComponentModel.Composition
    Imports Microsoft.LightSwitch.Theming
     
    Namespace Presentation.Themes
     
        <Export(GetType(IThemeExtension))>
        <ThemeExtension(MyTheme.ThemeId)>
        Friend Class MyStyle
            Implements IThemeExtension
     
            Public Function GetControlStyleResources(themeId As String, themeVersion As String, modules As IEnumerable(Of Microsoft.LightSwitch.Model.IModuleDefinition)) As IEnumerable(Of Uri) Implements IThemeExtension.GetControlStyleResources
                Return New List(Of Uri) From {New Uri("/MyThemeExtension.Client;component/Presentation/Themes/MyTheme.xaml", UriKind.Relative)}
            End Function
        End Class
     
    End Namespace

    Now when you run and test your extension you will see that the buttons have the rounded-corner style!

    If you prefer, as I do, to use ExtensionsMadeEasy so you can modify your theme from inside your Lightswitch application, change the theme class to inherit from EasyThemeWithExtensionExporter instead of EasyThemeExporter and implement IThemeExtension:

    Imports ExtensionsMadeEasy.ClientAPI.Theme
    Imports Microsoft.LightSwitch.Theming
    Imports System.ComponentModel.Composition
     
    Namespace LightSwitchApplication
     
        Public Class MyTheme
            Inherits EasyThemeWithExtensionsExporter(Of MyTheme, MyTheme)
            Implements ITheme, IThemeExtension
     
            Public ReadOnly Property ColorAndFontScheme As Uri Implements ITheme.ColorAndFontScheme
                Get
                    Return New Uri(String.Format("/{0};component/Theme/{1}", Me.GetType.Assembly.FullName.Split(",")(0), "MyTheme.xaml"), UriKind.Relative)
                End Get
            End Property
     
            Public ReadOnly Property Id As String Implements ITheme.Id
                Get
                    Return "My Theme"
                End Get
            End Property
     
            Public ReadOnly Property Version As String Implements ITheme.Version
                Get
                    Return "1.0"
                End Get
            End Property
     
            Public Function GetControlStyleResources(themeId As String, themeVersion As String, modules As IEnumerable(Of Model.IModuleDefinition)) As IEnumerable(Of Uri) Implements IThemeExtension.GetControlStyleResources
                Return New List(Of Uri) From {New Uri(String.Format("/{0};component/Theme/{1}", Me.GetType.Assembly.FullName.Split(",")(0), "MyTheme.xaml"), UriKind.Relative)}
            End Function
     
        End Class
     
    End Namespace

    Either method will allow you to use your own styles for the buttons in Lightswitch.

    Latest Microsoft Visual Studio LightSwitch Forum Threads That Have Answers

    following this code from this link: https://social.msdn.microsoft.com/Forums/vstudio/en-US/479cbc96-6ec2-4d9f-b2f8-a2b43a09111e/html-client-dynamically-count-records-in-a-collection-on-browse-screen?forum=lightswitch I have got my screen to count how many rows are present when the screen first loads. In my scenario I have a add button located on the bottom navigation bar. this opens up a dialog window where the user can add the relevant information. However when the user hits save, and is navigated back to the browse screen, the count still displays the previous value. If i was to refresh the page it updates but this is not what i am after, when i navigate back i want the value to add by one, am i missing something in this code?             screen.ExpanderLines.addChangeListener("state", function() {                     screen.countExp = screen.ExpanderLines.data.length;

    I have a browse screen to display query results in a table. This for a large table and there are 50+ query parameters that the user can enter.  The query parameters are all on a separate screen. 1.  I need a button on the separate screen that when clicked will clear (set null or undefined??) all of the parameters, to allow the user to reset the search.  The screen properties that are the parameters are of all different types (bool, string, details picker/entity, date).  Is there a way to get them all without having to do setPropertyName() for each one manually? 2. Related to question 1, is there a way to iterate through the properties and get a reference based on the type of property? I'm going to take a look at the contentItem properties and methods and try to get this working but was wondering if anyone knows any tricks before I spend hours digging around. Thanks!

    I think this has been asked before, but darn I can't find it. I working with VS2013 on a Lightswitch desktop app. If I add a row to a SQL Server table via Lightswitch and the table has an Identity column, how do I find the value of the Identity column for the row I just added? I want to both tell it to the user and be able to retrieve the row later. Thanks in advance.
