Why do you want to learn Silverlight 3? It's at version 5 now, and it's way ahead in terms of functionality.

|

actually i just need to know all the difference between silverlight versions thats why? i knew about earlier versions..

If you are very new to the language, going through a book would be a better bet.

Hi All,
I need C1Flexgrid for WPF to be used as a usercontrol in my windows application project. I tried to do by inheriting the C1Flexgrid for WPF, but created user control is not listing in the toolbox. When I inherited normal DataGrid, its working fine. Can anyone help me out from this problem.
Thanks and Regards

I am thinking of doing an article on Silverlight treeview (I know done to death but I like to think I have an interesting take on the design) and was thinking of the bits required. I would probably use AdventureWorks for the data. Now here is the stray thought!
WCF services are pretty much a no brainer, especially if you only want to supply select functionality, so why does Microsoft not set up a public WCF to service all the demo/article/sample requirement for AdventureWorks. Allow anyone to get a List<> of any table or view in the database.

Thank you, presumably this is exactly what I was looking for, a WCF of the AdventureWorks data.

Hi, I am using the following code below to save and load the changes a user makes to shapes on a canvas (called 'myCanvas'). So I use the XamlWriter to save the entire Canvas to a file and the XamlReader to read. The XamlWriter writes appropriately but after calling the XamlReader the Canvas does not update with the saved content.
Am I missing a step?
private void Window_Loaded(object sender, RoutedEventArgs e)
{
FileStream fs = new FileStream("savedproperties.xml", FileMode.Open);
myCanvas = (Canvas)XamlReader.Load(fs);
}
private void Window_Closed(object sender, EventArgs e)
{
FileStream fs = new FileStream("savedproperties.xml", FileMode.Create);
XamlWriter.Save(myCanvas, fs);
}

Please how can I Fill a shape with horizontal or vertical lines only.

Thanks for your suggestion, Abhinav, though it didn't really help. But I guess that's because I still need to understand some graphics/wpf basics.

In my view model I have:
private void loadUserSettings()
{
OptionsAreaExpanded = Properties.Settings.Default.OptionsAreaExpanded;
ShowActiveContactsOnly = Properties.Settings.Default.ActiveContactsOnly;
}
private void saveUserSettings()
{
Properties.Settings.Default.OptionsAreaExpanded = OptionsAreaExpanded;
Properties.Settings.Default.ActiveContactsOnly = ShowActiveContactsOnly;
Properties.Settings.Default.Save();
}
The loadUserSettings method is called from the CTOR. Where's the right place to call saveUserSettings from.

In winforms there is an onclosing, I wonder if there is the same on a view. I used that in this article[^].

I'd like to create this[^] blue area on a window.
I'm thinking a border to start with, but as far as the gradient, I'm not sure how to do that.
Any suggestions?

Heres a thought, why don't you download the source code from the example and chase through the style/xaml. Assuming of course that Karl has not supplied it as a theme.

Hello,
I have an object with 3 properties- Field, Value, Operator. Also i have a list of this objects.
In my DataGrid i have an operator column which is static.
All other columns are added dynamically using dependency properties (adding column from the object - using Field Attribute).
The same object contains the value so the value will be presented in the cell under the right column (Field) .
All objects that have the same operator will be presented in one row in the DataGrid.
How can i do it? How do i use Dependency properties for this (if i need)?

While creating style for a button I am writing like this:
<Style x:Key="MagButtonStyle" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Image Name="Normal" Source="Resources/Images/n0.png"/>
<Image Name="RollOver1" Source="Resources/Images/r1.png" Visibility="Hidden"/>
<Image Name="RollOver2" Source="Resources/Images/r2.png" Visibility="Hidden"/>
<Image Name="RollOver3" Source="Resources/Images/r3.png" Visibility="Hidden"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="Normal" Property="Visibility" Value="Hidden"/>
<Setter TargetName="RollOver1" Property="Visibility" Value="Visible"/>
</Trigger>
</Style>
Can we control this trigger by some global variable/ dependency property defined in c# code? So, we would be able to use it with Multi-trigger?
Basically my requirement is to display different images based on property "DepProp". I need to be able to wrtite something like this:
<Trigger Property="DepProp" Value="1">
<Setter TargetName="RollOver1" Property="Visibility" Value="Visible"/>
</Trigger>
<Trigger Property="DepProp" Value="2">
<Setter TargetName="RollOver2" Property="Visibility" Value="Visible"/>
</Trigger>
Is it possible?
Other way around would be to access these style objects on mouseenter in c# code. Possible? If yes, how?
Which way will be better?

I have the same problem:
I need to put lines with different colors in a datagrid base on what happens in code behind.
I think one solution will be to attach a style with a trigger from the code behind.
Of course I wait to see how can access a code declared dependency property from xaml.
Maybe with a DataTrigger.

I wouldn't approach it like this. A simpler way to do this would be to implement a value converter which did the heavy work of just displaying the appropriate image, rather than showing and hiding elements.

Thanks! Yes your approach is better one. I opted for INotifyPropertyChanged and sorted out my issue.

I have solved my problem like here:
http://msdn.microsoft.com/en-us/library/system.windows.datatrigger.aspx
http://msdn.microsoft.com/en-us/library/ms668604.aspx
and I can put different colors in my grid based on the normal property from the Item class.

Thanks for sharing those links. Meanwhile I sorted out my requirement using 'INotifyPropertyChanged'.

I'm reading this[^].
If you scroll down a bit you will see this:
<Canvas>
<Canvas.Resources>
<ControlTemplate x:Key="DesignerItemTemplate" TargetType="ContentControl">
<ContentPresenter Content="{TemplateBinding ContentControl.Content}"/>
</ControlTemplate>
</Canvas.Resources>
<ContentControl Name="DesignerItem"
Width="100"
Height="100"
Canvas.Top="100"
Canvas.Left="100"
Template="{StaticResource DesignerItemTemplate}">
<Ellipse Fill="Blue"/>
</ContentControl>
</Canvas>
What does this do?
<Canvas.Resources>
<ControlTemplate x:Key="DesignerItemTemplate" TargetType="ContentControl">
<ContentPresenter Content="{TemplateBinding ContentControl.Content}"/>
</ControlTemplate>
</Canvas.Resources>
It looks like its biding the ContentPresenter to the controls content. Isn't that the default behavior anyway?
