I'm so new to this that I can't even phrase the question right...
Anyway, I'm trying to do something very simple and have been unable to figure it out. I have the following class:
public class Day : Control, INotifyPropertyChanged
{
public static readonly DependencyProperty DateProperty =
DependencyProperty.Register("Date", typeof(int), typeof(Day));
public int Date
{
get { return (int)GetValue(DateProperty); }
set
{
SetValue(DateProperty, value);
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs("Date"));
}
}
}
public static readonly DependencyProperty DayNameProperty =
DependencyProperty.Register("DayName", typeof(String), typeof(Day));
public String DayName
{
get { return (String)GetValue(DayNameProperty); }
set
{
SetValue(DayNameProperty, value);
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs("DayName"));
}
}
}
static Day()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(Day), new FrameworkPropertyMetadata(typeof(Day)));
}
#region INotifyPropertyChanged Members
public event PropertyChangedEventHandler PropertyChanged;
#endregion
}
I've learned that you can't call a constructor that has parameters in XAML so the only way to actually set some data for this class is through the two properties, DayName and Date.
I created a ControlTemplate for Day which is as follows:
<Style TargetType="{x:Type con:Day}">
<Setter Property="MinHeight" Value="20"/>
<Setter Property="MinWidth" Value="80"/>
<Setter Property="Height" Value="20"/>
<Setter Property="Width" Value="80"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type con:Day}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Rectangle Grid.ColumnSpan="2" x:Name="rectHasEntry" Fill="WhiteSmoke"/>
<TextBlock Grid.Column="0" x:Name="textBlockDayName" Text="{TemplateBinding DayName}" FontFamily="Junction" FontSize="11" Background="Transparent"
HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,2,0,0"/>
<TextBlock Grid.Column="1" x:Name="textBlockDate" Text="{TemplateBinding Date}" FontFamily="Junction" FontSize="11" Background="Transparent"
HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,2,0,0"/>
<Rectangle Grid.ColumnSpan="2" x:Name="rectMouseOver" Fill="#A2C0DA" Opacity="0"
Style="{StaticResource DayRectangleMouseOverStyle}"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I then render it on screen in my MainWindow thusly:
<Window x:Class="WPFControlLibrary.TestHarness.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:con="clr-namespace:WPFControlLibrary.Calendar;assembly=WPFControlLibrary"
Title="MainWindow" Height="500" Width="525"
WindowStartupLocation="CenterScreen">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="80"/>
</Grid.ColumnDefinitions>
<con:Day Grid.Column="1" Height="20" Width="80" DayName="Mon" Date="1"/>
</Grid>
And what I actually see is, well, nothing. If I put my cursor on the con:Day line of the XAML it'll highlight the correctly sized rectangle in the window but I don't see "Mon" on the left side of the rectangle and "1" on the right.
What am I doing wrong? I suspect it's something simple but I'll be darned if I'm seeing it.
My ultimate goal is to group a bunch of the Day controls within a Month control, which is then contained in a Year control as I'm trying to make a long Calendar Bar that lets you navigate through the months and years, while clicking on a Day would display any information saved on that date. But I can't even get the Day part to display independent of anything else so I'm a long way from the rest of the functionality. Any help would be greatly appreciated.
