Converter works:
<UserControl.Resources>
<BooleanToVisibilityConverter x:Key="MyBooleanToVisibilityConverter" />
</UserControl.Resources>
...
<Button Name="btnSomeButton" HorizontalAlignment="Left" Grid.Row="0" Grid.Column="0" Click="btnSomeButton_Click" Width="40px" Height="40px" Visibility="{Binding Path=bIsVisible, ElementName=SomeControl, Mode=TwoWay}" >
<Image Source="..\Icons\SomeIcon.jpeg" ToolTip="SomeButton" />
</Button>
In above example, bIsVisible is a simple CLR property of type Boolean.
But as with any other "Enum", you do NOT need a converter, you could have binded a property of type "System.Windows.Visibility" directly to your control:
<Button Name="btnSomeCmd" HorizontalAlignment="Left" Grid.Row="0" Grid.Column="3" Click="btnSomeCommand_Click" Width="40px" Height="40px" Visibility="{Binding Path=SomeButtonVisibility, ElementName=SomeControl, Mode=TwoWay, diagnostics:PresentationTraceSources.TraceLevel=High}" >
<Image Source="..\Icons\...; ToolTip="SomeCommand" />
</Button>
In above example, SomeButtonVisibility is a dependency property of type System.Windows.Visibility. I used a Dependency Property as supposed to a common CLR property only because I want take advantage of "Two Way" notification.

I am trying to build a sideways scrolling chart using SilverLight 3. I want to display multiple pieces of data that span a set of numerical values; however, the values are not parallel as they are in a bar chart that has a standard base value for each piece of data. Think of it as a Gantt chart with the top scale being zipcodes and the data being cities that contain the zipcodes. The data would be represented as a horizontal bar that spans a set of zipcodes. I actually looked into modifying a Gantt chart; however, since its primary function is to display data over a period of time, I am not certain if it will work.
Can anybody point me in a possible direction to solve my problem?

My application using 'Pages' and i using wpf navigation to navigate between the pages.
I cant to control the page size and the page location on the screen and i don't know how - because i don't see that there is option to setup the page container.
I see that the page himself has the edit option of width and height - but i want that the size will be as 'auto' mode - and i want to have the ability to use 'auto' of the size change ( case the user will change the page container size => the page size will be change automatically also )

I fancy expanding my Very Limited knowledge and would appreciate a link to an Idiots Guide in order to have a play around and maybe make a few basic attempts at prettiness.
Recommendations?

Silverlight or WPF? The choice is very dependent on the tech.

You are most welcome. Life is good right now - I'm writing a Silverlight app with the Dr Who episode "The Lodger" on in the background.

Depends. Do you intend to use Expression Blend[^]?
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Hi,
I am trying to apply a style to a combo box but instead of getting applied the combo box itself disappears. Please check the following xaml code for user control.
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Luna"
x:Class="Guardian.PAS.PASFramework.UI.WPF.PASComboBox"
xmlns:local="clr-namespace:Guardian.PAS.PASFramework.UI.WPF"
Height="26" Width="100" VerticalAlignment="Center" >
<UserControl.Resources>
<Style x:Key="comboBoxStyle" TargetType="{x:Type local:PASCustomComboBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:PASCustomComboBox}">
<ControlTemplate.Triggers>
<Trigger Property="local:PASCustomComboBox.IsEnabled" Value="false">
<Setter Property="Background" Value="Red"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
<Canvas Name="canvas" Height="23" Width="Auto" VerticalAlignment="Center">
<Label Height="23" Name="lblCaption" Width="20" VerticalAlignment="Center">aaa</Label>
<local:PASCustomComboBox Height="23" x:Name="cmbComboBoxControl" VerticalAlignment="Center" Width="50"
IsEditable="True" Style="{StaticResource comboBoxStyle}">
</local:PASCustomComboBox>
<Button Height="23" Name="btnSearch" Width="25" Click="btnSearch_Click" Visibility="Collapsed"
VerticalAlignment="Center">...</Button>
<Label Height="23" Name="lblDescription" VerticalAlignment="Center" Width="20" Foreground="Blue">
</Label>
</Canvas>
</UserControl>
Here PASCustomComboBox is a class which inherites from combo box.
public class PASCustomComboBox : ComboBox
{
protected override void OnPreviewKeyDown(KeyEventArgs e)
{
if (e.Key == Key.Down || e.Key == Key.Up)
{
e.Handled = true;
return;
}
base.OnPreviewKeyDown(e);
}
}
Please help!
Thanks in advance!

When you set the Template property for a control, you're replacing the control with whatever is inside the template... In this case, you're replacing it with nothing, since the only thing you put inside your custom template is a trigger.
|
|
|
|
|
Oh... Then what should i write in the control template to show the current combo box as it is??? I am a little weak in xaml..!!
|
|
|
|
|
Don't use the Template unless you plan on replacing the entire control.

I have some user control that i wrote in simple C# winform.
I want to add it into WPF Window.
