Simple WPF ListView Binding Issue

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :WPF

I've uploaded a very simple test project with the issue here: http://www.2shared.com/file/sRVEBh42/KvpTest.html (or here)


The basic problem is, I have a ListView bound to a property on my class. The property is of type ObservableCollection<ObservableKeyValuePair<string, string>>.

I created the ObservableKeyValuePair so I can do two-way binding.


My ListView has 2 columns, Key, and Value. The Value column has a custom DataTemplate which is simply a TextBox, with its Text property setup with a two-way binding (so the user can edit the values of the ObservableCollection<ObservableKeyValuePair<string, string>>.

In my property's setter, I place a breakpoint however it never gets it. The setter of the ObservableKeyValuePair<string, string> is getting hit instead. This seems right, but I need to also propagate that change to the class property my ListView is bound to so I can simply pass the property through to another class and it would contain the changes.

Any ideas how I can achieve this? The sample project is very simple and small if you don't mind downloading it.

Simple data binding question

Newbie binding question here: is it possible to bind a control in XAML to a StaticResource by passing in the key via a data structure? Basically something like this: <TextBlock Text="{Binding ImageKey}" /> <Image Source="{StaticResource ResourceKey={Binding ImageKey}}" /> <-- doesn't work   The TextBlock binding on the first line works correctly, it extracts the key of the StaticResource from my data structure and displays it correctly. What I'm trying to do is get the Image control to bind to the StaticResource with that name (which happens to be a BitmapImage).      

Command binding issue with using CommandReference and CommandGroup

I'm trying to write an app using the MVVM pattern but I'm running into an command binding issue. I'm trying to bind a button to multiple commands. To do this I'm using the CommandReference class (this is from the MVVM toolkit) and the CommandGroup class (I found this CodeProject). Here is a simplified version of my xaml: <Window.Resources> <c:CommandReference x:Key="TestCommand" Command="{Binding Path=TestCommand}"/> <c:CommandGroup x:Key="TestCommandGroup"> <c:CommandReference Command="{StaticResource TestCommand}"/> <c:CommandReference Command="{StaticResource TestCommand}"/> </c:CommandGroup> </Window.Resources> <Grid> <Button Content="Command Test" Command="{StaticResource TestCommandGroup}"/> </Grid> If I set the DataContext of the window to itself, this works just fine and the TestCommand will execute twice. The problem occurs when I want to follow the MVVM pattern and I set the DataContext of the window to a ViewModel. When I do this the button becomes disabled (I don't see any binding errors in the output window). I tried debugging this to see what was going on. If I set a breakpoint on the PropertyChangedCallback for the Command, I noticed the sequence this gets called is diff

Help - simple data binding

As a newbie I am struggling with the data binding syntax. In the code below I have used a class to create a simple data structure. (I need to be able to fill this from an array which I can do.) For this example I have filled it in directly. However, despite exhaustive searching in the web I cannot find a Visual Basic example showing me how to bind this data source to a Datagrid. I have included in the code the xaml for a basic data grid. Can anynbe help me with the xaml to bind the fields to textboxes?

INotifyCollectionChanged binding issue


I have an Observable Collection bound to a Datgrid. I want to be able to edit the contents of the Grid and have the bound Collection updated. I understand that I need to make the controls editable and implement INotifyCollectionChanged.


As ever I cannot find a Visual Basic version of this on the web (Express 2010) to unravel so as to understand the syntax. (Below is a working code example how far I have got with this)


I would appreciate any help on this.

Strange DataGridColumn Binding issue


Hi all,

I'm looking for a way to debug this problem I'm having with binding expressions in my DataGrid.

I've got a data grid that I create columns for on the fly in c# code.  I create DataGridTemplateColumns based on a data class that has an internal dictionary and implements ICustomTypeDescriptor.  I create columns for each of the dictionary's keys.  This all works just dandy, except for one thing.  My output window gets a bunch of these (one for each property):

System.Windows.Data Error: 39 : BindingExpression path error: 'ID' property not found on 'object' ''Object' (HashCode=17704875)'. BindingExpression:Path=ID; DataItem='Object' (HashCode=17704875); target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String')

To debug, I created a converter and removed the Path.  Usually, when I stop the debugger in the converter, the "object" parameter is what I would expect - an instance of my data object.  However, sometimes (as above), the "object" is just an "object" with no further defined type (thus causing this debug output).  I'm a bit at a loss as to why the "object" in the converter is not an instance of my data object. 

Again, all the code seems to work fine.  The data g

Listview selecteditem binding to textbox causing problems




I have listview and i have binded the listview selected item to a grid's datacontext. The grid contains a text box whose text property is bound to one of the columns in the listview. I have Add, Edit and Delete buttons to manipulate data in the listview.

Binding Issue


Hey guys,

I'm using the Microsoft Fluent Ribbon in an app I'm writing with a great deal of success...that said; I'm little by little moving my code to MVVM and really liking some of the benefits but at the same time running into some walls in the process...here's my issue:

The MS Fluent Ribbon's Ribbon Control has a SelectedTabIndex property which I'm trying to use in order to bind a TabControl's SelectedIndex property...problem is, the TabControl never changes value when I change tabs on the ribbon.  Apparently the Ribbon control sets its SelectedTabIndex to -1 between switching tab values, and as a result (just guessing) my binding isn't working.  I tried using a FallbackValue but it's had no effect (or doesn't accomplish what I want anyway)...does anyone have any possible suggestions?



If at first you don't succeed, skydiving is definitely not for you!

Strange time issue on simple select statement


Hi, I have a strange time out issue on a simple select statement.
This is my select statement:

Select * from DyGeJournal where ord>=4609635 and Fracsec>=31

The ord and Fracsec is the primary key.
When I ask for the actual excecution plan, he is using a an index seek.
It takes more than 1,5 minutes to get a result back.

When I shrink my database, everyting is running as expected, the query above runs in milliseconds.
After a while (2 weeks) it start agian running very slow.

I have the same logic on other tables, but I don't have the problem on those tables.
What can cause this problem?
