30,657,991 | 0 | Lightswitch nested autocomplete boxes <p>I have Lightswitch 2013 and need to have nested autocomplete boxes. All the examples on the Internet are for older versions of Lightswitch and there are just a few differences in their examples from my version. Example: When adding Data Item for Local Property, Type "someTable" (Entity) doesn't come up as a choice. Also, if I click on one of my tables, then when I drag this Local Property to the screen is doesn't create an autocomplete box. Seems simple, but frustrating when I've tried many different ways. Please provide specific example using Lightswitch 2013. Thanks in advance. Steve</p> |

39,037,943 | 0 | <p>Check if <code>remoteMessage.getNotification()</code> is not NULL. I think it is NULL because you are not sending the param 'notification' in your <code>$fields</code> array of your PHP code. You are sending 'data'. So, when you send the parameter 'data' you have to get that parameter with <code>remoteMessage.getData()</code>. </p> <p>Try to print the content of <code>remoteMessage.getData().toString()</code> in your onMessageReceived method. It should print the data you are sending in the notification.</p> <p>Hope this helps.</p> |

39,969,247 | 0 | <p>You have to answer twice, about where to install Java.

ORACLE's installer should have been done a little less ambiguously.</p> <p>If you try and answer the same directory, for the jre, as for the jdk, you won't have your jar.exe, or your src.zip folder. They are installed there, until it asks for the destination for the JRE. It might overwrite (remove all) the files in the root directory of the jre folder.

32,453,502 | 0 | <p>As far as I can see you're want to display list of entities, then provide an UI for selecting one of these entitites (via gridcontrol) and edit the selected entity properties in separate view (via text editors).</p> <p>So, I suggest you to use the MVVM approach. And, since you are already using DevExpress controls, I suggest you use the <a href="https://documentation.devexpress.com/#WPF/CustomDocument15112" rel="nofollow">DevExpress MVVM Framework</a> to make your MVVM as easy as it possible.</p> <p>Step 1: Define a ViewModel class that contains your entities collection available via the <code>Entities</code> property (you can load these entities in way as it needed, from it needed and when it needed) and provide the <code>SelectedEntity</code> property:</p> <pre><code>public class EntitiesViewModel { public EntitiesViewModel() { LoadEntities(); } void LoadEntities() { Entities = new ObservableCollection<Entity> { new Entity(){ Item1="A", Item2="A0", Item3="A00"}, new Entity(){ Item1="B", Item2="B0", Item3="B00"}, new Entity(){ Item1="C", Item2="C0", Item3="C00"}, }; } public ObservableCollection<Entity> Entities { get; private set; } public virtual Entity SelectedEntity { get; set; } // Bindable property } public class Entity { public string Item1 { get; set; } public string Item2 { get; set; } public string Item3 { get; set; } } </code></pre> <p>Step 2: Define a View layout as follows:</p> <pre><code>... xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:DXApplication1" xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core" xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors" xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid" xmlns:dxmvvm="http://schemas.devexpress.com/winfx/2008/xaml/mvvm" ... <Grid Margin="12"> <Grid.DataContext> <dxmvvm:ViewModelSource Type="{x:Type local:EntitiesViewModel}"/> </Grid.DataContext> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <Grid Grid.Row="0" Margin="0,0,0,8"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="8"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <Label Content="Item1" Grid.Row="0" VerticalAlignment="Center"/> <Label Content="Item2" Grid.Row="1" VerticalAlignment="Center"/> <Label Content="Item3" Grid.Row="2" VerticalAlignment="Center"/> <dxe:TextEdit Text="{Binding SelectedEntity.Item1}" Grid.Row="0" Grid.Column="2"/> <dxe:TextEdit Text="{Binding SelectedEntity.Item2}" Grid.Row="1" Grid.Column="2"/> <dxe:TextEdit Text="{Binding SelectedEntity.Item3}" Grid.Row="2" Grid.Column="2"/> </Grid> <dxg:GridControl Grid.Row="1" AutoGenerateColumns="None" ItemsSource="{Binding Entities}" SelectedItem="{Binding SelectedEntity}"> <dxg:GridControl.Columns> <dxg:GridColumn FieldName="Item1"/> <dxg:GridColumn FieldName="Item2"/> <dxg:GridColumn FieldName="Item3"/> </dxg:GridControl.Columns> <dxg:GridControl.View> <dxg:TableView ShowTotalSummary="True" AllowEditing="False"/> </dxg:GridControl.View> </dxg:GridControl> </Grid> </code></pre> <p>*The main points-of-interest and tricks are:<br> 1) creating the <code>EntitiesViewModel</code> instance via the ViewModelSource. This way allows you do not implement the <code>INotifyPropertyChanged</code> interface at the ViewModel's level - you can just declare the <code>SelectedEntity</code> property as <code>virtual</code> and delegate all the dirty-work to the <a href="https://documentation.devexpress.com/#WPF/CustomDocument17352" rel="nofollow">POCO mechanism</a>:</p> <pre><code><dxmvvm:ViewModelSource Type="{x:Type local:EntitiesViewModel}"/> </code></pre> <p>2) all View' controls bindings are "looks" into the DataContext (which contains our ViewModel):</p> <pre><code>... Text="{Binding SelectedEntity.Item1}" ... ItemsSource="{Binding Entities}" SelectedItem="{Binding SelectedEntity}"> </code></pre> <p>This way allows you to decouple all UI-controls from each other and modify the View with easy.</p> |

17,354,829 | 0 | <p>You'll need to create your own binder function to do that. The main reason for having <code>.bind()</code> was to deal with the non-lexically defined <code>this</code>.

5,621,324 | 0 | jQuery val() and checkboxes <p>Is there some rationale for <code>val()</code> being useless for checkbox controls, whereas it is useful for getting input data consistently across every other input control?</p> <p>e.g. for checkboxes, at appears to <em>always return "on" regardless of the checkbox state.</em> For other input controls that don't actually have a "value" attribute, e.g. select and textarea, it behaves as you would expect. See:</p> <p><a href="http://jsfiddle.net/jamietre/sdF2h/4/">http://jsfiddle.net/jamietre/sdF2h/4/</a></p> <p>I can't think of a good reason why it wouldn't return <code>true</code> or <code>false</code>. Failing that, at least return "on" only when checked, and an empty string when not. Failing that, at least always return an empty string, given that checkboxes have no <code>value</code> attribute!</p> <p>Obviously I know how to get the value using <code>attr</code>, but here's the situation. I am developing a simple (so far anyway) C# jQuery implementation to do HTML parsing on the server, and I am trying to be completely faithful to jQuery's implementation so it behaves consistently on either the client or server against the same DOM. But this just seems stupid and I'm having a hard time getting myself to actually code "value" to return "ON" for a checkbox no matter what. But if I don't, it won't be consistent. So I'm trying to understand, is there some reason for doing this? Does it serve some purpose, or is it simply an artifact of some kind? Would anyone ever use the <code>val()</code> method against a checkbox, if so, why? If not, why did the jQuery architects decide on this approach to make it not useful?</p> |
