WPF-TimePicker не обновляется

Я использую Time Picker из wpfToolkit.extended в приложении WPF.WPF-TimePicker не обновляется

Когда я выбираю время в dropdrownlist, все работает так, как должно. Это пространство имен инструментария.

xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"

Это XAML для timepicker

     } 
    } 


    #region INotifyPropertyChanged Members 
    public event PropertyChangedEventHandler PropertyChanged; 
    #endregion 

}

Он показывает ошибку, поскольку «StartPicker и EndPicker не существует в текущем контексте».

Предложите способы устранения этой ошибки.

Где вы написали эти два метода в? Они должны быть записаны в код за файлом соответствующего файла XAML. –

Да. Эти методы записываются в код позади соответствующего файла xaml. – user2622971

Можете ли вы показать еще какой-нибудь код вашего xaml.cs – Vishal

Xaml-

<Grid> 
      <xctk:TimePicker Name="StartPicker" TextBoxBase.TextChanged="StartPicker_TextChanged" Value="{Binding StartTimeBinding, ElementName=MainWin, UpdateSourceTrigger=PropertyChanged}" Format="Custom" FormatString="hh:mm tt" Background="Yellow" Padding="0" Margin="0" BorderThickness="0" Width="100" Height="50" EndTime="11:59:0"/> 

      <xctk:TimePicker Name="EndPicker" TextBoxBase.TextChanged="EndPicker_TextChanged" Value="{Binding StopTimeBinding, ElementName=MainWin1, UpdateSourceTrigger=PropertyChanged}" Format="Custom" FormatString="hh:mm tt" Background="Yellow" Padding="0" Margin="0" BorderThickness="0" Width="60" Height="50" EndTime="11:59:0"/>   

    </Grid>

Code-Behind вашей Xaml в Xaml.cs

private void EndPicker_TextChanged(object sender, TextChangedEventArgs e) 
     { 
      StartPicker.Focus(); // shows error at TimePicker Name(i.e StartPicker) 
     } 

     private void StartPicker_TextChanged(object sender, TextChangedEventArgs e) 
     { 
      EndPicker.Focus(); // shows error at EndPicker 
     }

То же, что и я. – user2622971

Попробуй так:

private void StartPicker_TextChanged(object sender, TextChangedEventArgs e) 
{ 
    TimePicker tp = sender as TimePicker; 
    if(tp != null) 
    { 
     tp.Focus(); 
    } 
} 

private void EndPicker_TextChanged(object sender, TextChangedEventArgs e) 
{ 
    TimePicker tp = sender as TimePicker; 
    if(tp != null) 
    { 
     tp.Focus(); 
    } 
}

Конечно, вы можете иметь только одну функцию и точка от обоих таймеров к этой функции:

private void TimePicker_TextChanged(object sender, TextChangedEventArgs e) 
{ 
    TimePicker tp = sender as TimePicker; 
    if(tp != null) 
    { 
     tp.Focus(); 
    } 
}

, а затем в XAML:

<xctk:TimePicker Name="StartPicker" TextBoxBase.TextChanged="TimePicker_TextChanged" Value="{Binding StartValue, ElementName=MainWin, UpdateSourceTrigger=PropertyChanged}" Format="Custom" FormatString="hh:mm tt" Background="Yellow" Padding="0" Margin="0" BorderThickness="0" Width="100" EndTime="11:59:0"/> 
<xctk:TimePicker Name="EndPicker" TextBoxBase.TextChanged="TimePicker_TextChanged" Value="{Binding EndValue, ElementName=MainWin, UpdateSourceTrigger=PropertyChanged}" Format="Custom" FormatString="hh:mm tt" Background="Yellow" Padding="0" Margin="0" BorderThickness="0" Width="60" EndTime="11:59:0"/>
