    <p>I want to create a user control for getting a date from the user. It should have three textboxes, one for year, month and day. I don't know how to create it.</p> <pre><code>&lt;UserControl x:Class="UI.WPF.CustomControls.ChooseDateControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" x:Name="chooseDateControl" xmlns:custom="clr-namespace:UI.WPF.CustomControls" d:DesignHeight="26" d:DesignWidth="181" FontFamily="Tahoma"&gt; &lt;DockPanel LastChildFill="True"&gt; &lt;Grid&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="1.5*" /&gt; &lt;ColumnDefinition Width="14" /&gt; &lt;ColumnDefinition Width="1*" /&gt; &lt;ColumnDefinition Width="14" /&gt; &lt;ColumnDefinition Width="1*" /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Label Content="/" Grid.Column="1" /&gt; &lt;Label Content="/" Grid.Column="3" /&gt; &lt;custom:NumericTextBox x:Name="txtYear" ToolTip="سال" Text="{Binding ElementName=chooseDateControl, Mode=TwoWay, Path=Year}" MaxLength="4" TabIndex="2" MinWidth="20" /&gt; &lt;custom:NumericTextBox x:Name="txtMonth" Grid.Column="2" ToolTip="ماه" Text="{Binding ElementName=chooseDateControl, Mode=TwoWay, Path=Month}" MaxLength="2" TabIndex="1" MinWidth="20" /&gt; &lt;custom:NumericTextBox x:Name="txtDay" Grid.Column="4" ToolTip="روز" Text="{Binding ElementName=chooseDateControl, Mode=TwoWay, Path=Day}" MaxLength="2" TabIndex="0" MinWidth="20" /&gt; &lt;/Grid&gt; &lt;/DockPanel&gt; </code></pre> <p></p> <p><strong>Code Behind</strong></p> <pre><code>public partial class ChooseDateControl : UserControl { public static readonly DependencyProperty ValueProperty; public static readonly DependencyProperty YearProperty; public static readonly DependencyProperty MonthProperty; public static readonly DependencyProperty DayProperty; static ChooseDateControl() { ValueProperty = DependencyProperty.Register( "Value", typeof(DateTime), typeof(ChooseDateControl), new FrameworkPropertyMetadata(DateTime.MinValue)); ValueProperty = DependencyProperty.Register( "Year", typeof(int), typeof(ChooseDateControl), new FrameworkPropertyMetadata((int)0)); ValueProperty = DependencyProperty.Register( "Month", typeof(int), typeof(ChooseDateControl), new FrameworkPropertyMetadata((int)0)); ValueProperty = DependencyProperty.Register( "Day", typeof(int), typeof(ChooseDateControl), new FrameworkPropertyMetadata((int)0)); } public ChooseDateControl() { InitializeComponent(); } public DateTime Value { get { return (DateTime)base.GetValue(ValueProperty); } set { base.SetValue(ValueProperty, value); } } public int Year { get { return (int)base.GetValue(YearProperty); } set { base.SetValue(YearProperty, value); } } public int Month { get { return (int)base.GetValue(MonthProperty); } set { base.SetValue(MonthProperty, value); } } public int Day { get { return (int)base.GetValue(DayProperty); } set { base.SetValue(DayProperty, value); } } } </code></pre> <p>It doesn't work correctly-- it returns the default value, which is DateTime.MinValue. Please help me.</p>

    1. COYou still need to fix your property registrations. You are registering everything to the ValueProperty. make sure you change to set the YearProperty, MonthyProperty, etc...

    2. COThere are aslo some problems with the logic to set the values, which for one you are never setting the Value property. You may want to look at the DatTimeUpDown control in the Extended WPF Toolkit to see how it is handled there: http://wpftoolkit.codeplex.com/

    3. COI am asuming you want to use the Value property as the property that is used for the databinding. This means you will have to handle the property changted call basck for the Value property to set the other property values. In the other propert callbacks you will probably want to set the Value property using the new D/M/Y combinations.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
