Hmmm, I might just get a new PC - I will have a look at the Video Card settings though and clear down a few things and see what happens. Thanks for your help.

You will need the right version of the .NET framework, a suitable version of Visual Studio or one of the express editions and to buy some books.
|
|
|
|
|
If youre already familiar with .NET, it's enough to read some articles here on CP.. It just takes a bit longer then.

I would really get some books. They are a big help (as long as they are the right ones).

In the code of a WPF custom control, I am updating Property1 in the Set{}
of another Property2(i.e. when another property changes). the Property1 is updated properly, but the updated value is not diaplayed in the Property Dialog Box of Visual studio. How can I get the updated value diaplyed in Property dialog box.
<br />
public string ControlID<br />
{<br />
get<br />
{<br />
return controlid;<br />
}<br />
set<br />
{<br />
controlid = value;<br />
Propertytoupdate = value;
<br />
}<br />
}<br />

One thing you need to do is implement INotifyPropertyChanged, and have the change notification raised when the property changes.

Each project you add to your solution will compile into an assembly.
If you add a project of Type: Class library, WPF User Control Library or WPF Custom Control Library, these will all compile into their own .dll.

Hello All,
Is there any way to bind TreeView with nested object without using HierarchicalDatatemplate?
For example:
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Grid>
<TreeView Margin="10,10,46,52" Name="familyTreeView"
/>
</Grid>
</Window>
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfApplication1 {
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window {
public Window1() {
InitializeComponent();
List<Person> _family = new List<Person>();
Person mom = new Person() { Name = "Hteik Tin May" };
mom.Children.Add(new Person() { Name = "Michael Sync" });
mom.Children.Add(new Person() { Name = "Shwesin Sync" });
mom.Children.Add(new Person() { Name = "Aye Nyein Thu" });
mom.Children.Add(new Person() { Name = "Kyaw Zin Thu" });
_family.Add(mom);
familyTreeView.ItemsSource = _family;
familyTreeView.DisplayMemberPath = "Name";
}
}
public class Person {
readonly List<Person> _children = new List<Person>();
public IList<Person> Children {
get {
return _children;
}
}
public string Name { get; set; }
}
}
It's not working without HierarchicalDatatemplate.
Any idea?
Thanks and Regards,

Any specific reason you don't want to use this HierarchicalDataTemplate?
You can always add TreeViewItems manually.

I want to depend on the structure of my object. not Hierachical DataTemplate which is static.
or Am I missing something?
What should I do if I want to change the level of treeview? For example: 2 level Hierachical structure to 5 level Hierachical
2 level Hierachical structure
-111
---22222
---22222
-333
---44444
---44444
5 level Hierachical structure
-111
---22222
--------333333333333
-------------44444444444
-------------------------55555
---22222
-333
---44444
---44444

Thanks

Hi All,
I'm having some trouble using some XAML and an attached property to vary a graphic in the UI. It seems to be intermittently working!! I was testing a Debug and Release version and all was working well but I've just fired it up again and its whacko!!
The XAML is:
<DataTrigger Binding="{Binding Path=(local:TreeViewItemProps.IsRootLevel),
RelativeSource={RelativeSource AncestorType={x:Type TreeViewItem}, Mode=FindAncestor}}" Value="True">
<Setter TargetName="img" Property="Source" Value="/SampleSort.Modules.Browser;component/Graphics/diskdrive.png" />
</DataTrigger>
<DataTrigger Binding="{Binding Path=(local:TreeViewItemProps.IsRootLevel),
RelativeSource={RelativeSource AncestorType={x:Type TreeViewItem}, Mode=FindAncestor}}" Value="False">
<Setter TargetName="img" Property="Source" Value="/SampleSort.Modules.Browser;component/Graphics/folder.png" />
</DataTrigger>
The error I get is:
Cannot convert string '/SampleSort.Modules.Browser;component/Graphics/diskdrive.png' in attribute 'Source' to object of type 'System.Windows.Media.ImageSource'. Cannot locate resource 'graphics/diskdrive.png'.
I don't get why its randomly stopped working. I haven't touch *any* code since working on this app yesterday!

Jammer,
If you're testing a Boolean value, then you only need one trigger and not two. Assign one of the images as the default and trigger on the other value to swap.
If this drives you crazy and you can't get it to work, I've always just used a TemplateSelector to solve issues like this.
