Hiren,

Can you rephrase your question. Its not clear what you need help with.

FYI: In WPF you can add almost any control to ItemsControl.

I am newbie in WPF. I don't know much about item Control.

I want to use TreeListView in my project. something like

http://www.codeproject.com/KB/list/treelistview.aspx

but above one is in win form i want to use in WPF window.

TreeView with checkbox as well as expander button(+,-) like in win explorer.
And ListView containing ComboBox, DateTimeControl and textbox.

Also tell me from where do i start learning WPF.
Triggers, XAML, items control, data binding etc.

Thanks

Hiren,

There are tutorials here on Code Project.

Both Josh Smith and Sacha Barber has writen great tutorials.

You can also use the Internet to research any topic in WPF.

You can also purchase a book from Amazon.com.

I like Matthew McDonald's book on WPF. He has one for C# and VB.NET.

You can use the WPF TreeView control to do what you want.

Suggest doing an Internet search on "wpf treeview" and you'll get plenty of examples.

Cheers, Karl

WPF Expression Blend Font Display Errors

Have you read the MSDN documentation or did a Google search on Triggers and Events?

There are also many WPF tutorials here on Code Project written by Josh Smith and Sacha Barber.

Greetings all and happy new year!

My WPF application, in the menu and other areas, for some reason is not displaying my "Arial" font properly. I don't understand what's going on. All my menu (and other items) have Arial font. Albeit some have a different size or thickness (e.g. bold or normal). However, it's all Arial. In addition, it shows up normal in the preview window. However, when I run it, it displays words using different sizes and weights for the letters in a given word.

Any ideas about what I can do?

Thanks in advance.

Could you post the snippet code of your XAML code ?

BlitzPackage19-Jan-09 17:15

19-Jan-09 17:15

Thanks for replying. Below is a code snippet from the menu.

<Menu Margin="0,0,0,0" Grid.ColumnSpan="3" Grid.Row="1" x:Name="MenuMain" Background="{DynamicResource BrushLinearGradientGray}">
<MenuItem FontFamily="./Fonts\#Arial" FontSize="14" FontWeight="Normal" Foreground="{DynamicResource SecondaryGradient}" HorizontalContentAlignment="Center" Padding="2,6,0,0" VerticalContentAlignment="Center" Margin="0,0,0,0" x:Name="MenuItemPersonalize" Width="94.516" Height="30.883" d:IsStaticText="True" Header="Personalize">
<MenuItem Header="Mode" x:Name="MenuItemMode" Foreground="#FF000000" Background="{DynamicResource SecondaryGradient}"/>
<MenuItem Header="Settings" x:Name="MenuItemSettings" Background="{DynamicResource SecondaryGradient}" Foreground="#FF000000"/>
</MenuItem>

</Menu>

Sorry if it looks jumbled, I don't know yet how to post code in these forums. Any help or direction would be greatly appreciated.

You must use > instead of >

Have you ever tried FontFamily="Arial" instead of the yours

BlitzPackage19-Jan-09 18:40

19-Jan-09 18:40

Thanks so much! That fixed it.

See, Expression Blend generated: "#Arial". Once I wrote "Arial", like you suggested, it worked.

Thanks again.

EventSetter error ?

Mohammad Dayyan19-Jan-09 9:32

19-Jan-09 9:32

Hey experts .
I've created several Grid in my App.

<Grid x:Name="GridShanbe0"> 
.
.
.
</Grid>

Then I've created a style in App.xaml file for all of them :

<Style TargetType="{x:Type Grid}">
	<EventSetter Event="UIElement.MouseLeftButtonDown" Handler="Grid_MouseLeftButtonDown" />
</Style>

But whenever I'm gonna compile the App, this error has occurred

'WPF.App' does not contain a definition for 'Grid_MouseLeftButtonDown' and no 
extension method 'Grid_MouseLeftButtonDown' accepting a first argument of type 
'WPF.App' could be found (are you missing a using directive or an assembly reference?)

I'm sure I've created Grid_MouseLeftButtonDown method.

What's wrong ?
Thank you

But where have you created it? I seriously doubt it's in App.xaml - and that's what the error is telling you, it's looking there for this handler.

I've created it in Window1.xaml.cs file.

Thus, must I write the style in App.xaml ?

As Pete said, you've got the Style in App.xaml.

Try putting the Style and code in Window1.

Thus , when we're gonna create EventSetter, we must put it in the same file with the element.
Is it true ?

Yes.

This question doesn't seem to have anything to do with WPF, WCF or WF, so you shouldn't post it in this section. Saying that, I'm feeling in a nice mood so I'll answer this for you. What you can do is create a memory mapped file and use this - this[^] article is a good place to get information on how to do this.
