I have a custom datepicker with me and i am trying to set focus to this using attached property. I have the toolkit version 3.5.50211.1 which was released on Feb 2010. The focus is working fine when i do DatePicker.Focus();
in my code. My custom datepicker code is as follows:
-- My DatePicker
using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Windows.Controls; 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; using System.Data; using System.ComponentModel; using System.Windows.Controls.Primitives; namespace Guardian.PAS.PASFramework.UI.WPF { public class PASDatePicker : DatePicker { #region Attached Property /// <summary> /// Get of IsFocus Property. /// </summary> /// <param name="obj"></param> /// <returns></returns> public static bool GetIsFocus(DependencyObject obj) { return (bool)obj.GetValue(IsFocusProperty); } /// <summary> /// Set of IsFocus Property. /// </summary> /// <param name="obj"></param> /// <param name="value"></param> public static void SetIsFocus(DependencyObject obj, bool value) { obj.SetValue(IsFocusProperty, value); } public static readonly DependencyProperty IsFocusProperty = DependencyProperty.RegisterAttached( "IsFocus", typeof(bool), typeof(PASDatePicker), new UIPropertyMetadata(false, OnIsFocusPropertyChanged)); /// <summary> /// Property change event of IsFocused. /// </summary> /// <param name="d"></param> /// <param name="e"></param> private static void OnIsFocusPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { var uie = (UIElement)d; if ((bool)e.NewValue) { // Don't care about false values. (uie as PASDatePicker).Focus(); } } #endregion } }
I am using this datepicker in my code and trying to set focus using the Isfocus attached property defined above.
-- test form xaml
<Window x:Class="Guardian.PAS.BARSLibrary.Test.frmPASDatePickerTest" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="frmPASDatePickerTest" Height="300" Width="300" xmlns:my="clr-namespace:Guardian.PAS.PASFramework.UI.WPF;assembly=Guardian.PAS.PASFramework.UI.WPF"> <Grid> <my:PASDatePicker Name="dtpDate" Height="25" Margin="64,40,64,0" VerticalAlignment="Top" my:PASDatePicker.IsFocus ="{Binding GoviddateissuedFocused}" /> <Button Height="23" Margin="64,90,139,0" Name="button1" VerticalAlignment="Top" Click="button1_Click">change</Button> </Grid> </Window>

Now when I click on change button the datepicker does not get the focus.
