how to bind to ElementName obtained from my ViewModel

Posted By:      Posted Date: October 01, 2010    Points: 0   Category :WPF

I want to set the focus of my window to one of two buttons. The buttons are inside a stackpanel. Which button has focus will depend on a property on my ViewModel. I am using FocusManager.FocusedElement to set the focus in the stackpanel properties like this:

             <StackPanel ... blah blah blah.... FocusManager.FocusedElement="{Binding ElementName={Binding Path=YesDefaultButton}}"> 

The examples ive seen for FocusedElement look like this   FocusManager.FocusedElement="{Binding ElementName=button1}"

But I want to decide which button in my viewmodel, the yesDefaultButton I have used above returns a string with the name of the button I want to bind to...but code I have above in my stackpanel crashes - am i on the right track for dynamically binding to an element name?

MVVM: How to bind a page in a tab control with a viewmodel?

We practise MVVM pattern.
We have a main window which contains tab controls. Each tabItem contains a page.
Since the main window needs to share some data with one of page, so our MainWindowViewModel creates the instance a RunconditionViewModel.
Then we need to set the instance of RunconditionViewModel to one of page's DataContent (page called ControlPage.xaml).
How do we achieve that? see the code below.

In HDMainWindow.xaml,
<TabControl x:Name="tabControlMain" DockPanel.Dock="Left" MinHeight="200"  SelectedIndex="0" TabStripPlacement="Left" >
<TabItem Header="Run" Name="TabItemControlPage"> <Frame Name="FrameControlPage" Source="Features\Basic Control\ControlPage.xaml"></Frame> <!--<Frame Source="Features\Basic Control\LoginPage.xaml"></Frame>--> </TabItem> in App.xaml.cs,

protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); InitializeComponent(); HDMainWindow hd = new HDMainWindow(); HDMainWindowViewModel hwd = new HDMainWindowViewModel(); hd.DataContext = hwd; //if (hd.TabItemControlPage != null) // hd.TabItemControlPage.DataContext = hwd.RunConditionsViewModel; if (hd.FrameControl

MVVM Bind View Details to Model Via ViewModel when a Button clicked.


I have model called Car with prperties name,model,type,year.

I have implemeted the Viewmodel with same properties with OnpropertyChangedEvent including model object type Property.

I have a view usercontrol where textboxes for name, model and for year a combobox.

Whenever i fill the view i want to save those details into model via view model

I have written ICommand  Save which calls SaveCarDetails defined in viewmodel,  which is bind to a button in view ,All other texboxes text is bind to the properties of viewmodel properties.

When i put break point at ICommand SaveCommand and SaveCarDetails Function i could see the values filled from view.

But when i bind these details to another user control where listbox is placed and its itemsource property is set to Car property nothing but model object defined in the viewmodel.

I couldn't see the values binding via viewmodel to model.

Where as if i bind to textboxes in the listview i could see the values because i it's a dependency property.

Can any one please tell me what is the wrong i am doing here.




Dialogs and ViewModel - Using Tasks as a Pattern

The ViewModel/MVVM pattern continues to gain popularity, with a blog post showing up every so often, and with tweets and retweets popping up even more often :-). At the same time, there are some interesting topics beyond the core pattern that continue to fuel experimentation. A big one amongst those is how should applications use dialogs when using the view model pattern.

The crux of the problem is the desire to keep the view model independent of UI concerns, and ensure it can be tested in a standalone manner, but that often comes to odds when you want the view model to launch a dialog, and/or do some work after the dialog is closed.

A Generic Dialog ViewModel

I worked on a wpf viewmodel for dialogs, because it seemed strange to me that you needed for instance windows forms dialogs to open or save files in wpf. So I set about creating my own wpf dialogs. After creating the dialog viewmodels there still remained a small issue with the library and also I didn't have much time to write an article about it. I however published the library containing the viewmodels for dialogs with another article on my blog

.NET Reflection: Dynamically Bind Your Data Layer to Stored Procedures and SQL Commands Using .NET M


One major inconvenience of using SQL stored procedures from code is having to match type information. You have to write long wrapper functions around the procedures just to expose the data types. In the .NET Framework, however, the reflection services of the System.Reflection namespace allow you to query rich metadata that describe data types. This article explains how to use reflection in .NET to end your stored procedure nightmares. The author creates four custom classes, including one that generates a SQLCommand object based on the metadata of a method. Using this library, you'll be on your way to automating the generation of stored procedures.

listview 3.5 bind dropdownlists edit item template VB.NET


I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If IsPostBack Then
            If Session("ACTIVETAB").ToString() = Session("SUBCONTRACTSATABNO").ToString() Then
            End If
        End If
    End Sub

    Public Function loadlookups(ByVal id As String, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) As DataTable
        Select Case id
            Case "ddlCertReceived"
                dt = GetLookupTable("SubcontractsA", "Sub 1 Cert Received")
                Dim ddlCertReceived As DropDownList = _
                CType(e.Item.FindControl("ddlCertReceived"), DropDownList)
                ddlCertReceived.DataSource = dt
                ddlCertReceived.DataTextField = "lup_text"

Viewmodel property not set to [Required] yet getting error message saying it is?


I have a viewmodel that i use for my view

public int SelectionId{ get; set; }        
public IEnumerable<Selections> Selections { get; set; }

Notice that SelectionId is not decorated with [Required]. In my view, i use DropDownFor like this:

<%= Html.DropDownListFor(m => m.SelectionId, new SelectList(Model.Selections, "Id", "Name"), "--- Select ---")%>

It should be possible to not select anything from the dropdown, resulting in model.SelectionId = 0, which is fine. Why do i get a "SelectionId field is required" error when i Post?  If i do this:

<%= Html.DropDownList(mySelectionId, new SelectList(Model.Selections, "Id", "Name"), "--- Select ---")%>

I no longer get the error if i dont select anything, which is what i want - but no way to bind it to the id if the user does select something

thanks for any help!
