not set component in model

I need to insert data from usercontrol into database.
I tried to set xml component into my model but it results in System.NullReferenceException.
Where is the problem ? How can I solve this?
usercontrol.cs:
public partial class League : UserControl
{
private Leagues _leagueVM;
public Leagues LeagueVM
{
get
{
_leagueVM.EnLeagueName = txtLeagueNameEN.Text;
_leagueVM.FaLeagueName = txtLeagueNameFA.Text;
_leagueVM.LeagueLogo = imgLogoLeague.Name;
return _leagueVM;
}
set
{
txtLeagueNameEN.Text = _leagueVM.EnLeagueName;
txtLeagueNameFA.Text = _leagueVM.FaLeagueName;
imgLogoLeague.Name = _leagueVM.LeagueLogo;
}
}
public League()
{
var leagueManager = Inject.Container.GetInstance<ILeagueService>();
InitializeComponent();
}
private void Image_MouseDown(object sender, MouseButtonEventArgs e)
{
FileDialog dialog = new OpenFileDialog();
dialog.ShowDialog();
}
private void btnInsertLeague_Click(object sender, RoutedEventArgs e)
{
var leagueManager = Inject.Container.GetInstance<ILeagueService>();
leagueManager.Add(LeagueVM);
}
}

</GroupBox>

It seems you missed to create a Leagues object and assign it to _leagueVM.
Should be easy to see if you use the debugger.

Creating a new instance of a window I have created. Called multiple times to do different things

I have created a window which is a numbered keypad :
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBox Name="btnTotal" Width="280" Height="60" Grid.ColumnSpan="3" Grid.Row="0" Margin="10,10,10,10" Background="#302F37" Foreground="AntiqueWhite" FontSize="35"></TextBox>
<Button x:Name="btnZzero" Content="0" Width="80" Height="60" Grid.Column="0" Grid.Row="4" Margin="5,5,5,5" Background="#302F37" Foreground="White" Focusable="False" Click="btnZzero_Click"></Button>
<Button x:Name="btnOk" Content="OK" Width="80" Height="60" Grid.Column="1" Grid.Row="4" Margin="5,5,5,5" Click="btnOk_Click" Background="#FF8FC377" Focusable="False"></Button>
<Button x:Name="btnCancel" Content="Cancel" Width="80" Height="60" Grid.Column="2" Grid.Row="4" Margin="5,5,5,5" Click="cancel_Click" BorderBrush="Black" Background="#FFD64D4D" Focusable="False"></Button>
<Button x:Name="btnOne" Content="1" Width="80" Height="60" Grid.Column="0" Grid.Row="3" Margin="14,6,0,6" Focusable="False" Background="#302F37" Foreground="White" HorizontalAlignment="Left" Click="btnOne_Click"></Button>
<Button x:Name="btnTwo" Content="2" Width="80" Height="60" Grid.Column="1" Grid.Row="3" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White" Click="btnTwo_Click"/>
<Button x:Name="btnThree" Content="3" Width="80" Height="60" Grid.Column="2" Grid.Row="3" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White"/>
<Button x:Name="btnFour" Content="4" Width="80" Height="60" Grid.Column="0" Grid.Row="2" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White"></Button>
<Button x:Name="btnFive" Content="5" Width="80" Height="60" Grid.Column="1" Grid.Row="2" Margin="5,5,5,5" Focusable="False" Background="#302F37" Foreground="White"></Button>

Now, I would like to call this keypad at different times in my application to do different things.
IE I want to use it for a login screen :
<Window x:Class="WpfApplication2.MainLogin2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainLogin2" WindowState="Maximized" Width="1024" Height="768" WindowStyle="None" WindowStartupLocation="CenterScreen">
<Grid Background="#FF260538">
<Grid.RowDefinitions>
<RowDefinition Height="768" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1024" />
</Grid.ColumnDefinitions>
<TextBox Name="userIDTextBox" HorizontalAlignment="Left" Height="47" Margin="402,249,0,0" TextWrapping="Wrap" Text="User ID" VerticalAlignment="Top" Width="213" FontSize="30" PreviewMouseDown="userIDTextBox_PreviewMouseDown" />
<TextBox Name="passcodeTextBox" Height="47" Margin="402,317,0,0" TextWrapping="Wrap" Text="Passcode" VerticalAlignment="Top" Width="213" FontSize="30" HorizontalAlignment="Left" PreviewMouseDown="passcodeTextBox_PreviewMouseDown" />
<Button Content="OK" HorizontalAlignment="Left" Margin="402,386,0,0" VerticalAlignment="Top" Width="213" Height="59" FontSize="30" Click="okButton_Click"/>
<Button Content="CANCEL" HorizontalAlignment="Left" Margin="402,450,0,0" VerticalAlignment="Top" Width="213" Height="59" FontSize="30" Click="cancelButton_Click_1"/>
</Grid>
My problem is how do I pass the result from the keypad back to different text fields after I have clicked ok?
Here is the code behind the keypad window. I only have the number 1 working so far for testing:
namespace WpfApplication2
{
public partial class QuantityKeypad : Window
{
bool btnClicked = false;
string quantityResult = "";
public QuantityKeypad()
{
InitializeComponent();
}
private void cancel_Click(object sender, RoutedEventArgs e)
{
this.Close();
}
private void btnOk_Click(object sender, RoutedEventArgs e)
{
this.Close();
}
private void btnZzero_Click(object sender, RoutedEventArgs e)
{
}
private void btnOne_Click(object sender, RoutedEventArgs e)
{
if (btnClicked == true)
{
btnTotal.Text = "";
btnClicked = false;
}
quantityResult = quantityResult += "1";
btnTotal.Text = quantityResult;
}
private void btnTwo_Click(object sender, RoutedEventArgs e)
{
}
}
}
And here is the code for the login screen :
namespace WpfApplication2
{
public partial class MainLogin2 : Window
{
public MainLogin2()
{
InitializeComponent();
}
//OK button
private void okButton_Click(object sender, RoutedEventArgs e)
{
MainWindow mainWindow = new MainWindow();
mainWindow.Show();
this.Close();
}
//Cancel button - takes user back to login screen
private void cancelButton_Click_1(object sender, RoutedEventArgs e)
{
this.Close();
}
//Removes text from login textboxes when clicked in
//opens instance of Quantitykeypad when clicking inside textbox
private void userIDTextBox_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
userIDTextBox.Text = "";
QuantityKeypad loginKeypad = new QuantityKeypad();
loginKeypad.Owner = this;
loginKeypad.ShowDialog();
}
//Removes text from passcode textboxe when clicked in
//opens instance of Quantitykeypad when clicking inside passcode textbox
private void passcodeTextBox_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
passcodeTextBox.Text = "";
QuantityKeypad loginKeypad = new QuantityKeypad();
loginKeypad.Owner = this;
loginKeypad.ShowDialog();
}
}
}
Terribly sorry if this is simple but I have been struggling for days now.
Thanks

You can make your private field quantityResult a publicly accessible property instead:
public string QuantityResult { get; private set; }
That way, you can read from it:
passcodeTextBox.Text = "";
QuantityKeypad loginKeypad = new QuantityKeypad();
loginKeypad.Owner = this;
loginKeypad.ShowDialog();
passcodeTextBox.Text = loginKeypad.QuantityResult;

How to do validation for Combobox value to match the database value?

I'm create an module which is a Editing Bill module which will enable the user to edit the available in the database. I'm facing one validation problem which is that when the user don't want to edit the bill & click on the "Cancel" button will back to the listview to continue select another record. Here is my problem come as when the user didn't make any modification & accidentally click on the "Status" combo from "UNPAID" to "PAID" then directly quite. When re select the record then the record status value will become "PAID" instead of "UNPAID" which is the actual value.
How can I do so that when every time the user don't make any modification & return back to the listview will set back the default value for the combobox.
Thank you all for viewing this question & hope to receive reply :)
I will attach my code so that easily to refer:

For this case it would be better to user IDataErrorInfo interface instead of using ValiationRule since IDataErrorInfo will be handled inside ViewModel where you also have all the necessary database statements.
Here is a link to a tutorial explaining how to do validation with IDataErrorInfo.
http://codeblitz.wordpress.com/2009/05/08/wpf-validation-made-easy-with-idataerrorinfo/
Have fun :)

I solved it by like this:
Code-Behind:
The problem that I faced is NullReferenceException then I used a try..catch to catch the "NullReferenceException"
private void comboBox3_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
ComboBoxItem currentItem = ((System.Windows.Controls.ComboBoxItem)BillStatusCboBox.SelectedItem);
try
{
if (currentItem.Content.Equals("PAID"))
{
BillPaidDatedatePicker.IsEnabled = true;
// BuilderupdateButton.Visibility = Visibility.Visible;
}
else
{
BillPaidDatedatePicker.IsEnabled = false;
}
}
catch (NullReferenceException ex){ // At here which you can see.
//I purposely set it to do nothing when catch it.
}
Then when the user accidentally click on the "UPAID" to "PAID" & directly click on the cancel button will invoke "NoButton_Click" which will try to reload & select the value from the database:
private void NoButton_Click(object sender, RoutedEventArgs e)
{
ShowData(); // Invoke & select from database again.
// NoButton Clicked! Let's hide our InputBox.
InputBox.Visibility = System.Windows.Visibility.Collapsed;
}
I know by this way solving my problem will be quite inefficient but get the job done :) Which is fine to me.

passing values between two pages wpf

I am learning c# and I have been asked to work on a project using WPF, which I don't know much. We are using MUI as well.
I am trying to achieve a pretty basic task. I have two pages called ClientRNG.xamland ServerRNG.xaml. In ClientRNG.xaml I have two buttons and two textfield, when each button is pressed a random number is generated and it appears in a text box. In ServerRNG there are just one button and one textfield, with the same functionality as mentioned above.
So I'll end up with three different random numbers, one in ServerRNG.xaml and two in ClientRNG.
What i want to do is to pass these random numbers to another page called SSL.xaml.
The pages are created in MainWindow.xml:
<mui:ModernWindow.MenuLinkGroups>
<mui:LinkGroup DisplayName="network security">
<mui:LinkGroup.Links>
<mui:Link DisplayName="Home" Source="/Pages/Home.xaml" />
<mui:Link DisplayName="RNG" Source="/Pages/ClientRNG.xaml" />
<mui:Link DisplayName="3DES" Source="/Pages/3des.xaml" />
<mui:Link DisplayName="RSA" Source="/Pages/RSA.xaml" />
<mui:Link DisplayName="SHA-1" Source="/Pages/sha1.xaml" />
<mui:Link DisplayName="PKI Certificates" Source="/Pages/pki.xaml" />
<mui:Link DisplayName="SSL" Source="/Pages/SSL.xaml" />
</mui:LinkGroup.Links>
</mui:LinkGroup>
<mui:LinkGroup DisplayName="settings" GroupName="settings">
<mui:LinkGroup.Links>
<mui:Link DisplayName="software" Source="/Pages/Settings.xaml" />
</mui:LinkGroup.Links>
</mui:LinkGroup>
</mui:ModernWindow.MenuLinkGroups>
<mui:ModernWindow.TitleLinks>
<mui:Link DisplayName="settings" Source="/Pages/Settings.xaml" />
</mui:ModernWindow.TitleLinks>
Code in ClientRNG:
namespace NetworkSecuritySSLTest.Pages
{
/// <summary>
/// Interaction logic for RNG.xaml
/// </summary>
public partial class ClientRNG : UserControl
{
public ClientRNG()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
Random r = new Random(1);
int number = r.Next(0, 100);
r1Out.Text = number.ToString();
SharingManager.GlobalValue = number;
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
Random r = new Random(3);
int number = r.Next(0, 100);
pmsOutC.Text = number.ToString();
}
here is the code I have in ServerRNG:
namespace NetworkSecuritySSLTest.Pages
{
/// <summary>
/// Interaction logic for RNG.xaml
/// </summary>
public partial class ServerRNG : UserControl
{
private SplitPage1 sp;
public ServerRNG()
{
InitializeComponent();
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
Random r = new Random(2);
int number = r.Next(0, 100);
r2Out.Text = number.ToString();
SharingManager.GlobalValue = number;
}
}
}
and this is the code behind SSL class
namespace NetworkSecuritySSLTest.Pages
{
/// <summary>
/// Interaction logic for SplitPage1.xaml
/// </summary>
public partial class SplitPage1 : UserControl
{
private int r1FromClient;
public SplitPage1()
{
InitializeComponent();
SharingManager.ValueChanged += UpdateTextBox1;
SharingManager.ValueChanged += UpdateTextBox2;
}
public void UpdateTextBox1(object sender, NumericEventArgs e)
{
r1SSLBox.Text = e.Value.ToString(); // Update textBox
}
public void UpdateTextBox2(object sender, NumericEventArgs e)
{
r2SSLBox.Text = e.Value.ToString(); // Update textBox
}
}
}
here are the xaml:

Now I was trying to use the solution posted by Omribitan but i am still struggling

According to what you said in the comment section that SplitPage1 is already shown,
What you are doing in your code is creating a new instance of SplitPage1 and passing it your data
SplitPage1 sp = new SplitPage1(); // This is a new page, not the one currently shown in your application
sp.Setr1SSLBox(number); // it should set the text box in SSL page
So if you want to set the text of the currently displayed SplitPage1, you need to get it's reference. It's hard to say how because I can't see your entire code but this is what I would consider:
Using IoC container to resolve the current instance of SplitPage1.
According to your code seems like there is a third party creating these pages. If that's true, it could pass ServerRNG a reference of the SplitPage1 it's creating which you'll be able to use later, for example :
public partial class ServerRNG : UserControl
{
private SplitPage1 sp;
public ServerRNG(SplitPage1 splitPage) : this()
{
sp = splitPage; // Save a reference to the currently displayed `SplitPage1` page
}
public ServerRNG()
{
InitializeComponent();
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
Random r = new Random(2);
int number = r.Next(0, 100);
r2Out.Text = number.ToString();
sp.Setr1SSLBox(number); // Set the correct instance's text
}
}
Create a class which will expose a static property and event that will fire when that property changes:
public class SharingManager
{
// Define a global static event to be fired when the value is changing
public static event EventHandler<NumericEventArgs> ValueChanged;
public static int GlobalValue
{
set
{
// Fire ValueChanged event
if (ValueChanged != null)
ValueChanged(null, new NumericEventArgs(value));
}
}
}
public class NumericEventArgs : EventArgs
{
public NumericEventArgs(int value)
{
Value = value;
}
public int Value { get; set; }
}
Register a handler in SplitPage1
public SplitPage1()
{
InitializeComponent();
SharingManager.ValueChanged += UpdateTextBox;
}
public void UpdateTextBox(object sender, NumericEventArgs e)
{
r1SSLBox.Text = e.Value.ToString(); // Update textBox
}
In Button_Click_1 on ServerNRG, update the value to fire the event
Random r = new Random(2);
int number = r.Next(0, 100);
r2Out.Text = number.ToString();
SharingManager.GlobalValue = number;
Hope this helps

you should work on WPF using the MVVM design pattern.
Its kinda annoying without MVVM framework
I suggest you to use http://caliburnmicro.codeplex.com/
use this tutorial to get started
http://www.mindscapehq.com/blog/index.php/2012/01/12/caliburn-micro-part-1-getting-started/
it also explains how to use the mediator pattern (using caliburn micros event aggerator) to pass values/commands between diffrent windows.

WPF- TimePicker is not updating

I'm using Time Picker from wpfToolkit.extended in WPF application.

It shows error as "StartPicker and EndPicker does not exist in current context".
Suggest the ways to solve this error.

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 your Xaml in 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
}

Try it this way:
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();
}
}
Of course you can have only one function and point from both timepickers to this function:
private void TimePicker_TextChanged(object sender, TextChangedEventArgs e)
{
TimePicker tp = sender as TimePicker;
if(tp != null)
{
tp.Focus();
}
}
and then in the 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"/>
