It still doesn't stop (and I get a warning that if I don't set the web project as startup, I can't debug the RIA services stuff.

Do you have Visual Web Developer installed? When you install VS 2010, it includes this but in case you have chosen a different mode of install and omitted the Visual Web developer then it could be an issue. Do check and see.

I have "Visual Studio Web Authoring Component", but that was installed with VS2008.

Found this thread - it might help you.
Note: The workaround suggests that if VS2010 is run in administrator mode, this problem goes away.

Nope - it has no effect. I wonder if it's because I have VS2008 and all the SL3 stuff installed...

I had VS2008 installed and debugging VS 2008 did not create any issues for me.
I was however using SL3 even in VS2010 - so it could be something to do with having the SL3 and SL4 tools installed together.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Look at the OP - I found out what was wrong.

I've been messing around with C# for about a year or so and I thought I'd have a look to see what WPF is all about. However I'm having a problem. Here's the problem -
If I drag a control (Button, TextBox TextBlock ,whatever) and I try to access the FontFamily property in the Poperties window then the designer will crash with the following error -

If the properties window is in "categorized" mode then all of the categories are open except the "Text" category. Any attempt to open that category will crash the designer also, (obviously because it contains the TextFamily property).
Anyone have a clue what is going on? I have tried to do a Repair on the Visual Studio installation but that didnt sort it out. I'm using VS2010 by the way. I also have VS2008 installed and that doesnt suffer from the problem.
TIA

Make sure to do not add more than one item with the same identifier or key

I have a WPF application which contains a ListView defined to show the values for an item in a chart.
One of the fields, State, is supposed to change as the charted values cross warning and alarm barriers.
I built up the list (which was really only one item) as follows:
ObservableCollection<LegendValues> itemList = new ObservableCollection<LegendValues>();
LegendValues item = new LegenValues();
... define the initial values ...
itemList.Add( item );
myListView.ItemsSource = itemList;
item.State = "Warn";
I also have the binding set in XAML as TwoWay.
When I change the state in the item object, it does not change in the ListView. Is there something I'm missing?
Thanks,
Michael

INotifyProperty perhaps?

Well...according to the documentation all I need are two things. TwoWay link on the binding between the ItemSource object and the ListIndex, and the ObservableCollection. But I can add INotifyProperty and see if that helps.

ObservableCollection is only used to tell the binding engine when records have been added or removed from the collection. In order to watch changes to particular properties, you need to use INotifyPropertyChanged and raise the PropertyChanged event.

Have a read up on MVVM, in particular anything to do with the ViewModel portion of that design pattern and as Pete said it's all about the object INSIDE your ObservableCollection.

try to do add Updatesourcetrigger = Propertychanged to the xaml in addition to the two way, make sure that the object source bound property implement the INotifyPopertyChanged or is a dependency property

I am having an issue and have scoured the net looking for an answer and I still have yet to find one so I thought I would post here while continuing my search. I simply want to set SelectedItem to a string value and have it select that item from the combobox. Now I am adding my items to the combobox statically during design time and when I do this, SelectedItem doesn't work and always is null. However I just found out that when I add my combobox items during runtime, selectedItem works just fine. Now I would like to know why this is. I am guessing that it is some binding that automatically happens when adding them dynamically, but I would love to know how to get this working statically. Thanks!

Please specify which version of the framework you are using. Assuming that this is a WPF application.

Sorry this is WPF and I am working in VS2010 .Net 4.0.

hello
newbie to WPF, how do you set selected item for a list box?
<br />
SomeDataTab.Columns.Add("SomeData", typeof(string));<br />
SomeDataTab.Columns.Add("IsSelected", typeof(bool));<br />
<br />
Cmd = new SqlCommand(SQL, (SqlConnection)DevConn);<br />
...<br />
Rdr = Cmd.ExecuteReader();<br />
while (Rdr.Read())<br />
{<br />
rw = SomeDataTab.NewRow();<br />
SomeData = (string)Rdr["SomeData"];<br />
if (SomeData == "TEMPLATE_OBJECTIVE")<br />
{<br />
SomeData = "SharedData";<br />
rw["IsSelected"] = true;<br />
}<br />
else<br />
{<br />
rw["IsSelected"] = false;<br />
}<br />
rw["SomeData"] = SomeData;<br />
SomeDataTab.Rows.Add(rw);<br />
}<br />
<br />
SomlstSomeData.DataContext = SomeDataTab.DefaultView;<br />
The above code shows how we bind to DataTable and following is xaml code:
<ListBox Name="lstSomeData" Grid.Row="0" Grid.Column="0">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<CheckBox IsChecked="{Binding IsSelected, Mode=TwoWay}" />
<Label Content="{Binding SomeData}"></Label>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
I wish to know how to pre-select say an Item with value "AAA"?
Thanks!

Is that you require something like this
[Code]<Grid>
<ComboBox Margin="37,31,299,251">
<ComboBoxItem IsSelected="True" Content="One"></ComboBoxItem>
<ComboBoxItem Content="Two"></ComboBoxItem>
<ComboBoxItem Content="Three"></ComboBoxItem>
</ComboBox>
</Grid>[/Code]
This code will show One item as selected by default at the compile time and not after firing the application

|
|

thanks but no, the list is built dynamically by binding to it a DataTable as shown in my code fragment
dev
|
|
|
|

You can do this progammatically by using the IsSelected = true of the given MenuItem in the code behid too if I well understand the question, I mean you can test the value AAA using the selected value property of the combo box and then set the IsSelected property of the corresponding item to true

Thanks no not really... In another post I've added more detail - basically (copied from there), I'm using CodePlex WPF ComboBox and is having trouble pre-select item
From code behind, I bind the combo box to a DataTable with two columns:
...
SomeTableSrc = new DataTable("SomeData");
SomeTableSrc.Columns.Add("Data", typeof(string));
SomeTableSrc.Columns.Add("IsSelected", typeof(bool));
lstSomeData.DataContext = SomeTableSrc.DefaultView;
Xaml:
<Style TargetType="{x:Type ComboBoxItem}">
</Style>
The above will select relevant "ComboBoxItem" (and it works fine, if you click on ComboBox, as menu expands you can see desired items actually get selected), *** BUT *** "SelectedValue" or "Text" of "ComboBox" (not items) remains blank - and setting these "ComboBox" attributes directly just don't work.
// Don't work, "ComboBox" text remains blank
lstSomeData.SelectedValue = "ABC";
// Don't work, "ComboBox" text remains blank
lstSomeData.Text = "ABC";
