Why is it htat in WPF, I make an object invisible and it still covers the UI so that stuff underneath cannot be clicked ? It makes XAML animations useless. I can fade something out, but I still need to catch the event where the animation ends so I can mark it as collapsed.

Hi,
I am trying to develop a CPU utilization Chart in Silverlight but can't seem to include System.Diagnostics.Process in the project. Can someone please point me in the right direction and advice me on the best way to implement the CPU utilization function.
I am using a Gauge to show my CPU utilization
Thanks

AFAIK you can't get the CPU usage info from a Silverlight application.

Hi All. I am working on a project with WPF (DataGrid) and ADO.NET EF.
The relevant piece of the EF model is shown below. Notice the *--* relationship between Location and ArticleClass.
EF Model[^]
The datagrid in the right hand upper corner (A) lists all the names of the ArticleClasses
The datagrid on the bottom (L) lists all the available Locations.
WPF Form[^]
What I want to do is, when I check the CanHaveAsArticle checkbox of a certain ArticleClass in (A), that a relationship is made (remember the *--*) between the selected Locations in (L) and the checked ArticleClasses in (A).
How can I do this using databinding?
I've tried a ValueConvertor but the instance doesn't know which rows of (L) are selected.
[...]
<my:DataGrid.Columns>
<my:DataGridTextColumn Header="Name" Binding="{Binding Path=Name}" IsReadOnly="True" />
<my:DataGridCheckBoxColumn Header="CanHaveAsArticle" Binding="{Binding Path=Locations, Converter={StaticResource myRelationshipManager}}" />
</my:DataGrid.Columns>
[...]
I've thought about binding it to a property in the Window.xaml.vb file where the setter creates the relationship (something like Location.ArticleClass.Add(L.SelectedRow)) and the getter checks whether there is a relationship, but I dont seem to find out how.
Thanks,
Wouter

I have a WPF application with a ListBox containing the following values:
Item0
Item1
Item2
Item3
Item3
Item2
When an item is double-clicked I have a MessageBox showing "item " + ListBox1.SelectedIndex.ToString() + " was selected.". The SelectionMode for the listbox is set to Single.
Everything works fine for the first 4 items, double-clicking Item0 shows item 0 was selected. However, the last two show the first item that matches that value. Double-clicking the second Item3 says item 3 was selected when it should be item 4 and the second Item2 says item 2 was selected when it should say item 5. Also, the selection highlight will highlight both lines and leave one of the duplicates highlighted even when one of the items without a duplicate is selected.
What do I need to do to get the last two items to show that they are the ones being selected? Why is WPF looking at the value instead of the individual items? This works fine with a windows forms listbox.
Thanks for any help,
Brad

It work's fine on my machine - proper index and no multiselection. This is what I am using,
<ListBox Name="mulList" MouseDoubleClick="ListBox_MouseDoubleClick" SelectionMode="Single">
<ListBoxItem Content="Item 0"/>
<ListBoxItem Content="Item 1"/>
<ListBoxItem Content="Item 2"/>
<ListBoxItem Content="Item 3"/>
<ListBoxItem Content="Item 3"/>
<ListBoxItem Content="Item 2"/>
</ListBox>
private void ListBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
MessageBox.Show("item " + (sender as ListBox).SelectedIndex.ToString() + " was selected.");
MessageBox.Show("item " + mulList.SelectedIndex.ToString() + " was selected.");
}

Forgive me, but I'm still a little green with WPF. Your method worked fine for me when I added ListBoxItems at design time.
I was adding string items to the ListBox at runtime by:
ListBox1.Items.Clear();
for (int i = 0; i << listOfNames.count(); i++)
{
ListBox1.Items.Add(listOfNames.name[i]);
}
If I create a ListBoxItem and set it's content to the name and then add it, that worked:
ListBox1.Items.Clear();
for (int i = 0; i << listOfNames.count(); i++)
{
ListBoxItem listBoxItem = new ListBoxItem();
listBoxItem.Content = listOfNames.name[i];
ListBox1.Items.Add(listBoxItem);
}
I was using ListBox1.SelectedItem to return the value (in my case name) of what was selected. Now I have to create a ListBoxItem, set it to the SeletecdItem, and then grab the content. So much for thinking it was simple. 
Thanks again for your help.

I have the same problem. I think it's a bug in WPF.
I'm using .NET 4.0 Beta 2 on VS2010 and I'm on Windows 7RC. The application itself is targeting .NET 3.0.

Hi All,
I keep seeing examples using this method but I simply cannot find it on the Dispatcher in my UI controls ... has this been deprecated in 3.5 SP1 or something??
Cheers,

This method has deliberately been hidden by Microsoft - they state that it's an advanced method that should only be used with care. We had lengthy discussions in the WPF Disciples about this issue.

I seriously doubt you can do that. See here[^]

What ?
Could you elaborate what you are trying to achieve ?

Hello.
Beyond have a second 'blank' storyboard which is called when a storyboard completes, is there a way to reset the current board back to the start when it's done?
I have been tasked with creating a crazy complex UI design which uses a massive amount of animations created in Blend (if we had a TweenMax for WPF it's be two lines of code!), most of these animations need to reset to the start after they are through, and I'm loathed to create dozens of extra animations or put in alpha and then re-shift-back-to-the-start key frames on everything.
Regards, E.

Hi
Is there any way in silverlight to export the grid as PDF?
Is there any dll that will help?
Thanks in Advance

Currently, you pretty much need to do that on a server.
AFAIK there's no support for rendering UI elements to a bitmap in Silverlight 2.

Mark is 100 % correct, just grab your data send it to the server using a WCF service, in for instance XML format (just an string), and use any of the well know tools, isharptext I think it's free, then you have tall pdf, ...
