  • Can't check more than one RadioButton across multiple items in a Treeview

    - by Mike Johnston
    I’m using a TreeView control to present a list of Questions. Using the Prism.DataTemplateSelector, I'm loading a View (.xaml file) that represents a single Question into each node in the TreeView. In the View for that question is a ListBox containing RadioButtons (one for each item in a Picklist object that the ListBox is bound to). The radio buttons work as expected for the question, but when I check a RadioButton on another node/question in the TreeView, the check for the button in the Question I was editing before disappears. In other words, I'm only able to check one RadioButton in the whole list of Questions/Items bound to the containing TreeView. How do I group the RadioButtons in the ListBox to the scope of the single question instead of all the questions in the TreeView.

  • WPF, Setting property with single value on multiple subcontrols

    - by Andre van Heerwaarde
    I have a parent contentcontrol which displays data via a datatemplate. The datatemplate contains a stackpanel with several usercontols of the same type. I like to set the property only once on the parent control, it must set the value of the property on all the subcontrols. But if there is a way to do it on the stackpanel it's also OK. The template can be changed at runtime and the values need also to be propagated to the new template. My current solution is to implement the property on both parent and subcontrol and use code to propagate the value from the parent to all the subcontrols. My question is: is there a better or other ways of doing this?

  • Prism's ItemsControl seems to have a xaml parse error. Why?

    - by user158103
    I am at a loss as to why my Shell.xaml's ItemsControl is causing a parse error. I know the syntax is correct because I copied the Silvelright project files from a working project. Right now my only guess is that ItemsControl is dependent on something else. Here is the relevant xaml line for ItemsControl. <ItemsControl x:Name="Region" VerticalAlignment="Center" HorizontalAlignment="Center" Regions:RegionManager.RegionName="Region"/>

  • Passing parameters into ViewModels (Prism)

    - by vXtreme
    Hi I can't figure out how to pass parameters to my viewmodels from other views or viewmodels. For instance, I have a View called Customers. There is a grid inside, and if you double-click the grid, a new view is supposed to come up and allow you to edit that customer's data. But how will the View(Model) responsible for editing data know which customer it's supposed to open if I can't pass any parameters inside? EventAggregator is out of the question because I obviously can't create hundreds of eventargs, each for one view. And besides, it's a lousy solution. So far I was able to come up with: CustomerDataView custView = new CustomerDataView(customerId, currentContext); manager.Regions[RegionNames.Sidebar].AddAndActivate(custView); What do you think about this particular solution? Is this the way it's normally done? What I don't like about this is the fact that I lose out on automatic dependency injection by Unity.

  • How to Parse an XML (using XELement) having multiple Namespace ?

    - by Subhen
    Hi I , I get the followinng Xresponse after parsing the XML document: <DIDL-Lite xmlns="urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:upnp="urn:schemas-upnp-org:metadata-1-0/upnp/" xmlns:dlna="urn:schemas-dlna-org:metadata-1-0/"> <item id="1182" parentID="40" restricted="1"> <title>Hot Issue</title> </item> As per the earlier thread, When there is a default namespace in the document, you must parse it as if it were a named namespace. For example. XNamespace ns = "urn:schemas-upnp-org:metadata-1-0/DIDL-Lite/"; var xDIDL = xResponse.Element(ns + "DIDL-Lite"); But in my case I have four different name space. I am not getting any results after using the following query , I am getting the response , Not Yeilding any results: XNamespace dc = "http://purl.org/dc/elements/1.1/"; var vAudioData = from xAudioinfo in xResponse.Descendants(ns + "DIDL-lite").Elements("item") select new RMSMedia { strAudioTitle = ((string)xAudioinfo.Element(dc + "title")).Trim(), }; I have no clue whats going on as am new to it. Please help

  • Simple Binding question, unable to bind to button command in a DataTemplate using MVVM Light Toolkit

    - by deliberative assembly
    I've been attempting to bind to buttons within a DataTemplate without much success. The button does not fire. Button Click works successfully outside of the DataTemplate. Yet if I create a Click="button_click" the click button is fired. The Button Content binds perfectly as well. Example to illustrate.. Why does the command not fire? Advice on how this should be handled this? The example is a simplified version of my real problem, I am currently not using a Listbox. I only recreated the same problem with a listbox..

  • Instantiate ItemsPanelTemplate

    - by Stephan
    I'm trying to create a ItemsControl that has a separator between items, for example a control to create a navigation bread crumb. I want the control to be completely generic. My original method was to create extend ItemsControl, add a SeparatorTemplate property, and then have the class add separators to the ItemsHost of the ItemsControl. The problem with this approach is that if you add extra items to the container panel, the ItemGenerator gets confused and the items are out of order and don't get removed correctly. So my second plan was to create a completely new control that would emulate an ItemsControl, but the problem I'm running into is that I can't find a way to instantiate an ItemsPanelTemplate. I would like to provide an ItemsPanel property just like ItemsControl, but I can't then create a panel from that template. Can anyone think of a way to either instantiate an ItemsPanelTemplate or way to add controls to an ItemsControl's panel without breaking the ItemGenerator?

  • Assembly Version Conflicts with What is Already Bound

    - by davemackey
    I'm running Microsoft LightSwitch Beta 1 and have been creating an application which has been going great, but then I tried debugging after making a few minor changes and received the following error: "Could not load file or assembly 'SW_Resources.Commom, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The requested assembly version conflicts with what is already bound in the app domain or specified in the manifest. (Exception from HRESULT: 0x80131053)" I've tried emptying my cache in Firefox and IE but that doesn't seem to make any difference. I did discover if I right-clicked on the Solution and changed the version from 0.1 to 1.0 then it works fine. I had changed it to 0.1 b/c I wanted to reflect that it wasn't a release version...any thoughts on how to get around this issue the right way?

  • Show all objects on canvas in window

    - by Number8
    Hello -- We have a canvas with a large number of objects. The user can pan and zoom the view of the canvas. I am trying to figure out how to implement "show entire canvas" -- that is, zoom and center the canvas in the window to show all objects. We know the max and min X and Y coordinates. I am looking at our current zoom and pan implementations to try to figure out if there is a way to use them. Any suggestions on how to do this would be appreciated... Thanks.

  • Is it possible for the View to subscribe ViewModel CLR event?

    - by Vincent Leung
    Sometimes a view model needs to raise notifications, that a view should handle and do something in response, esp. when these can't be modeled as properties and property change notifications. Anything in MVVM Light that can allow the view to listen to events and translate view model notifications into user interface actions via declarative Xaml markup?

  • WPF: How to programmatically utilize the ErrorTemplate of an Control?

    Hi, is there a way to programmatically set and remove the ErrorTemplate of an Control without the whole Validation mechanism? Basically, what I'd like to do, is to retrieve the ErrorTemplate of an Control at some point like this: ControlTemplate errTemplate = Validation.GetErrorTemplate(myTxtBx); and temporarily use it as it's ControlTemplate like this: myTxtBx.Template = errTemplate; Can you somehow do this?

  • Retrieve baseUri w/o resorting to Application.Current

    - by beaudetious
    My custom controls are not loading in VS.NET's designer because of a null reference exception. It's got everything to do with the way I am retrieving the baseUri of the application when it runs in the browser: _uriPrefix = Application.Current.Host.Source.AbsoluteUri.Substring(0, Application.Current.Host.Source.AbsoluteUri.IndexOf("/ClientBin")).Trim(); According to the exception details and the help file I'm directed to (here) I'm not correctly designing my app for a runtime that's not the browser (i.e. the new WPF editor in VS.NET or Expression Blend). So, the question is how do retrieve the baseUri (the http://localhost:#### part of my application) if I can't use Application.Host which apparently is null during design time? is there a safe way to do this so I can load my custom controls in a designer?

  • Binding a combobox in XAML to a childwindow property

    - by AlexB
    Hi, I want to display a child window that contains a combobox with several values coming from one of the child window's property: public partial class MyChildWindow : ChildWindow { private ObservableCollection<MyClass> _collectionToBind = // initialize and add items to collection to make sure it s not empty... public ObservableCollection<MyClass> CollectionToBind { get { return _collectionToBind; } set { _collectionToBind = value; } } } How do I bind in XAML my combobox to the ComboBoxContent collection (both are in the same class)? I've tried several things such as: <ComboBox x:Name="linkCombo" ItemsSource="{Binding Path=CollectionToBind }" DisplayMemberPath="Description"> I've only been able to bind it in the code behind file and would like to learn the XAML way to do it. Thank you!

  • How to build the ViewModel in MVVM not to violate the Single Responsibility Principle?

    - by Przemek
    Robert Martin says: "There should never be more than one reason for a class to change". Let's consider the ViewModel class which is bound to a View. It is possible (or even probable) that the ViewModel consists of properties that are not really related to each other. For small views the ViewModel may be quite coherent, but while the application gets more complex the ViewModel will expose data that will be subject to change for different and unrelated reasons. Should we worry about the SRP principle in the case of ViewModel class or not?

  • using dictionaries with WebServices

    Hi! I tried to pass a dictionary via WebServices. However it is not serializeable. So i wrote an Own Class that makes it serializeable: using System; using System.Net; using System.Windows; using System.Collections.Generic; using System.Xml.Serialization; using System.Xml; using System.Xml.Schema; namespace Platform { public class SaDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable { #region Constructors public SaDictionary() : base() { } public SaDictionary(IDictionary<TKey, TValue> dictionary) : base(dictionary) { } public SaDictionary(IEqualityComparer<TKey> comparer) : base(comparer) { } public SaDictionary(int capacity) : base(capacity) { } public SaDictionary(IDictionary<TKey, TValue> dictionary, IEqualityComparer<TKey> comparer) : base(dictionary, comparer) { } public SaDictionary(int capacity, IEqualityComparer<TKey> comparer) : base(capacity, comparer) { } //protected SaDictionary(SerializationInfo info, StreamingContext context) // : base(info, context) //{ //} #endregion public XmlSchema GetSchema() { return null; } public void ReadXml(XmlReader reader) { XmlSerializer keySerializer = new XmlSerializer(typeof(TKey)); XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue)); bool wasEmpty = reader.IsEmptyElement; reader.Read(); if (wasEmpty) return; while (reader.NodeType != XmlNodeType.EndElement) { reader.ReadStartElement("item"); reader.ReadStartElement("key"); TKey key = (TKey)keySerializer.Deserialize(reader); reader.ReadEndElement(); //key reader.ReadStartElement("value"); TValue value = (TValue)valueSerializer.Deserialize(reader); reader.ReadEndElement(); //value this.Add(key, value); reader.ReadEndElement(); //item // reader.MoveToContent(); } reader.ReadEndElement(); } public void WriteXml(XmlWriter writer) { XmlSerializer keySerializer = new XmlSerializer(typeof(TKey)); XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue)); foreach (TKey key in this.Keys) { writer.WriteStartElement("item"); writer.WriteStartElement("key"); keySerializer.Serialize(writer, key); writer.WriteEndElement(); //key writer.WriteStartElement("value"); TValue value = this[key]; valueSerializer.Serialize(writer, value); writer.WriteEndElement(); //value writer.WriteEndElement(); //item } } } } However i get an ArrayOfXElement back.
