Hi all,
I am just beginning out with wpf, so sorry for what is probably an easy question! The reason for my interest in wpf is that I have an application that I need to run on several pcs with different resolutions. What I would like to do is have an area in the app with several buttons on. I want the area to be callable with several 'pages' - similar to using tabs, but I would scroll from left to right through the pages. Each page may have 10 - 20 buttons on it, which will be dynamically positioned on startup, and will resize depending on the resolution of the screen. Any suggestions on how to do this?
Thanks very much in advance

I think, you can make use of the layout controls to place your buttons ....

The best option is use third party control like Telerik, it provides professional way of scrolling, You can scroll pages like a book,
You also have option to scroll the pages like Photo Albumb which is really cool

Hey folks. I was wondering if anyone is thinking of upgrading to Adobe CS6 or will you be waiting or skipping the release. Some of our team members are on CS4 and some on CS5, what would you suggest we do regarding CS6. Will appreciate your advice and any experiences positive or negative you may have had with CS6

You should ask this in the lounge. Your question has nothing to do with WPF or Silverlight.

Hello,
I am new to WPF and am having a bit of trouble with a menu radio button item.
I have the following code snippets:
<Menu.Resources>
<ControlTemplate x:Key="Template" TargetType="{x:Type RadioButton}">
<Border Background="Transparent">
<MenuItem Header="{TemplateBinding Content}" IsCheckable="False" IsChecked="{TemplateBinding IsChecked}" IsHitTestVisible="False" Padding="2,3" HorizontalAlignment="Stretch">
</MenuItem>
</Border>
</ControlTemplate>
</Menu.Resources>
<MenuItem Header="Me">
<StackPanel>
<RadioButton Content="Foo" Template="{StaticResource Template}"/>
<RadioButton Content="Bar" Template="{StaticResource Template}"/>
<RadioButton Content="Biz" Template="{StaticResource Template}"/>
</StackPanel>
However, what ends up happening is that my check marks end up on the right side of the vertical menu separator as opposed to the left, as would happen normally using the IsChecked property.
Does anyone know a way to make these check marks appear to the LEFT of the vertical separator? All help is greatly appreciated.

I want to reuse some styles, so I created a resources file in the root of my project called AppResources.xaml.
I then copied the styles into it. At the top of my view, I replaced the styles with
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/Common;component/AppResources.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
Yet I get a compile error "An error occured while finding the resource dictionary 'pack://application:,,,/Common;component/AppResources.xaml'".
What's the right way to do this?
[UPDATE] Fixed it with <resourcedictionary source="..\Resources.xaml">
If it's not broken, fix it until it is

If you want to access a resource which is in different assembly, then use the pack URI as follows...
Pack://application:,,,/SampleAssembly;component/SampleFolder1/SampleImage.jpg
If you want to merge two resource dictionaries use the following code
suppose if Dictionary1 and Dictionary2 are your resource xaml files, then to merge these resources
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Dictionary1.xaml" />
<ResourceDictionary Source="Dictionary2.xaml" />
</ResourceDictionary.MergedDictionaries>
<SolidColorBrush x:Key="BlueBrush" Color="Blue" />
</ResourceDictionary>
</Window.Resources>

A quick look at the documentation[^] suggests the CellEnter and CellLeave events will give you what you need.

Hi,
I am trying to create stack bart chart in silver light with bars should come in horizental direction by following code
SeriesDefinition tempSeriesForSale1 = new SeriesDefinition();
tempSeriesForSale1.ItemsSource = saleUnits1;
tempSeriesForSale1.IndependentValuePath = "SalesDistrict";
tempSeriesForSale1.DependentValuePath = "saleFromOldCustomer";
//tempSeriesForSale1.Title = "Tik tik";
stackSeriesForSale.SeriesDefinitions.Add(tempSeriesForSale1);
Chart3.Series.Add(stackSeriesForSale);
With this code bars are coming in vertical direction. If I Interchange the Independentvaluepath and dependentvalue path then I gets exception.
Following is the code in .xaml file
<toolkit:Chart Name="Chart3" Title="Repeat Sales" VerticalAlignment="Top" Margin="33,330,176,0"
Height="262">
<toolkit:PieSeries ItemsSource="{Binding}" IndependentValuePath="Name"
DependentValuePath="Types" IsSelectionEnabled="True" >
</toolkit:PieSeries>
</toolkit:Chart>
Can someone please help?

[UPDATE] Got it working
I want to style a tooltip so that it looks like a Facebook tooltip[^].
In this design, there can be images, text, links, and buttons, as well as a little triangular pointer. So that leaves a couple of questions...
1) I was thinking that having multiple content presenters would allow me to define the style, and then when it's applied, set the image, text, links, etc. How do you set up multiple content presenters?
2) The triangular pointer... How do you get this to point to the correct spot depending on where the tooltip opens.
Thanks

Hi
I am basically trying to create a control that consists of a combobox and some buttons (add, clear etc). I realise I could do it by creating a usercontrol with some codebehind, but I am trying to achieve this by defining a custom control class and a style for the control.
I have done the below based on other custom controls I have done, but the issue I am having is that the ItemsSource is always null and never gets set.
[TemplatePart(Name = ComboBoxControl.INPUTCOMBOBOX_NAME, Type = typeof(ComboBox))]
public class ComboBoxControl : Control
{
#region Constants
const String CATEGORY_NAME = "Custom ComboBox Control";
const String INPUTCOMBOBOX_NAME = "PART_InputComboBox";
#endregion
#region Properties
ComboBox _inputComboBox;
#endregion
#region Dependency Properties
public static readonly DependencyProperty DisplayMemberPathProperty =
DependencyProperty.Register("DisplayMemberPath", typeof(string), typeof(ComboBoxControl), new UIPropertyMetadata(String.Empty));
public static readonly DependencyProperty ItemsSourceProperty =
DependencyProperty.Register("ItemsSource", typeof(IEnumerable), typeof(ComboBoxControl), new UIPropertyMetadata());
#endregion
#region Dependency Public Properties
public string DisplayMemberPath
{
get { return (string)GetValue(DisplayMemberPathProperty); }
set { SetValue(DisplayMemberPathProperty, value); }
}
public object ItemsSource
{
get { return (System.Collections.IEnumerable)GetValue(ItemsSourceProperty); }
set { SetValue(ItemsSourceProperty, value); }
}
#endregion
#region Constructor
public ComboBoxControl() { }
static ComboBoxControl()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(ComboBoxControl), new FrameworkPropertyMetadata(typeof(ComboBoxControl)));
}
#endregion
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
_inputComboBox = (ComboBox)GetTemplateChild(INPUTCOMBOBOX_NAME);
}
}
And the following style:
<Style TargetType="{x:Type local:ComboBoxControl}">
<Setter Property="Label" Value=""/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:ComboBoxControl}">
<Border>
<DockPanel>
<ComboBox x:Name="PART_InputComboBox" VerticalAlignment="Stretch" MinHeight="30"
DisplayMemberPath="{TemplateBinding DisplayMemberPath}"
ItemsSource="{Binding Path=ItemsSource, Mode=TwoWay, RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType={x:Type local:ComboBoxControl}}, UpdateSourceTrigger=PropertyChanged}"/>
</DockPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
NOTE: I have omitted irrelevant code.
And trying to set it like this:
<ctl:ComboBoxControl ItemsSource="{Binding Path=Users, Mode=TwoWay}"/>
But the value of the combobox itemsource is always null?!
Can anyone help please?
Thanks

Ok, I think I may have solved this, but if what I put below isn't the real solution, please let me know.
Where I was setting:
<ctl:ComboBoxControl ItemsSource="{Binding Path=Users, Mode=TwoWay}"/>
I hadn't set the datacontext of the control the combobox was being hosted in. i.e. DataContext = this;
|

If you haven't set a DataContext, then your binding would fail here so it would seem fair to say that you found your issue.

Hi!
What is the namespace to include for ShellExecute to compile?
I've to open a URL from WPF Emulator. How to do this? I tried <pre lang="c++">Process.Start()</pre>
But it opens many times. ShellExecute() doesn't compile.
It gives the following error:
The name 'ShellExecute' does not exist in the current context
How to open a URL in WPF?
|
|
|
|

I just use Process.Start to open a URL. Here's an example from the code I'm looking at right now:
public static void OpenUrl(string url)
{
if (string.IsNullOrWhitespace(url))
throw new ArgumentNullException("url");
Process.Start(url);
}
|
|
|

Pete O'Hanlon wrote:
Process.Start(url);
I've used this. It's opening the URL many times. I want only one time. How to do this? What about ShellExecute with WPF?
|
|
|
|
|
It only opens it once per execution - sounds like you're hooked into calling that many times - and you would have to write interop code for ShellExecute, where you'd still get the same issue. Put a breakpoint on your Process.Start code and see how many times it's being called.

Hi!
I've to change the state of the application to minimized before opening the URL.
I'm using this code.
<pre lang="c#">
#if WINDOWS
this.WindowState = WindowState.Minimized;
#endif
</pre>
But it shows the following error:
The name 'WindowState' does not exist in the current context
How to minimze the application before opening the URL?

You may need to use the FormWindowState enumeration as described here[^].
