background operation of user controller

I have prepared more than one UserControl for a windows program in XAML. Each user control works as a separate page. But I do page transitions in navigate class. In ".xaml.cs" when calling User control
Navigate.navigate (navigate_grid, new DeviceLayout ());
I'm using the line of code. But every time I create a new user control, the background functions don't work. How do I flip one instead of invoking a new user control each time?
class Navigate
{
public static void navigate(Grid grd, UserControl uc)
{
if (grd.Children.Count > 0)
{
grd.Children.Clear();
grd.Children.Add(uc);
}
else { grd.Children.Add(uc); }
}
}
Example navigate:
public SettingsView()
{
InitializeComponent();
Navigate.navigate(navigate_grid, new SystemLayout());
}
private void system_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new SystemLayout());
previous_page.Text = "";
current_page.Text = "SİSTEM";
next_page.Text = "UYGULAMA";
}
private void application_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new ApplicationLayout());
previous_page.Text = "SİSTEM";
current_page.Text = "UYGULAMA";
next_page.Text = "BAĞLANTI";
}
private void connection_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new ConnectionLayout());
previous_page.Text = "UYGULAMA";
current_page.Text = "BAĞLANTI";
next_page.Text = "ÜRÜNLER";
}
private void product_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new ProductsLayout());
previous_page.Text = "BAĞLANTI";
current_page.Text = "ÜRÜNLER";
next_page.Text = "CİHAZLAR";
}
private void device_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new DeviceLayout());
previous_page.Text = "ÜRÜNLER";
current_page.Text = "CİHAZLAR";
next_page.Text = "YAZICILAR";
}
private void printer_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new PrinterLayout ());
previous_page.Text = "CİHAZLAR";
current_page.Text = "YAZICILAR";
next_page.Text = "KULLANICILAR";
}
private void users_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new UsersLayout());
previous_page.Text = "YAZICILAR";
current_page.Text = "KULLANICILAR";
next_page.Text = "BAKIM";
}
private void maintenance_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new MaintenanceLayout());
previous_page.Text = "KULLANICILAR";
current_page.Text = "BAKIM";
next_page.Text = "HAKKINDA";
}
private void info_button_click(object sender, RoutedEventArgs e)
{
Navigate.navigate(navigate_grid, new InfoLayout());
previous_page.Text = "BAKIM";
current_page.Text = "HAKKINDA";
next_page.Text = "";
}
}
Not sure if I get what you mean.
When you change the UserControl with the use of any of those functions eg info_button_click you can't access this funtion anymore.
That would be the case, because your XAML and .cs file are one class, containing those funcitons. If you change the UserControl (XAML) you will also change the .cs file. Therefore you can't access those functions anymore.
You could probably get the behaviour you want if you bind the commands to a viewmodel, which you could then pass through the navigation as well?
Sry, I'm still not sure what exactly it is you're doing.

populating a listbox from another window, but on second attempt the list is replaced instead of added

I'm building a task list application.
From my main window, I click on the add button. The program generates a new Window,and I compete the form and close it with the complete button.
My listbox in the main window has been populated with the tasks that I have entered.
The problem is, when I do this again, the listbox items are replaced with new items instead of the ones being added.
MainWindow.cs
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
List<Task> allTasks = new List<Task>();
private void Window_Loaded(object sender, RoutedEventArgs e)
{
}
private void addTaskBtn_Click(object sender, RoutedEventArgs e)
{
NewTaskWindow newTaskWindow = new NewTaskWindow();
newTaskWindow.Owner = this;
newTaskWindow.Show();
}
private void editTaskBtn_Click(object sender, RoutedEventArgs e)
{
}
private void searchBtn_Click(object sender, RoutedEventArgs e)
{
}
private void AddUserBtn_Click(object sender, RoutedEventArgs e)
{
}
private void markCompleteButton_Click(object sender, RoutedEventArgs e)
{
}
private void deleteTaskBtn_Click(object sender, RoutedEventArgs e)
{
}
}
NewTaskWindow.cs
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Windows;
namespace Task_Managment
{
public partial class NewTaskWindow : Window
{
Task newTask = new Task();
public NewTaskWindow()
{
InitializeComponent();
}
ObservableCollection<Task> AllTasks = new ObservableCollection<Task>();
ObservableCollection<Task> taskList = new ObservableCollection<Task>();
private void Window_Loaded(object sender, RoutedEventArgs e)
{
string[] taskType = new string[3];
taskType[0] = "Home";
taskType[1] = "College";
taskType[2] = "Work";
CataCombo.ItemsSource = taskType;
}
public void completeBtn_Click(object sender, RoutedEventArgs e)
{
List<Task> allTasks = new List<Task>();
newTask = new Task
{
Title = titletxBx.Text,
Description = DesctxBx.Text,
Priority = prioritytxBx.Text,
Catagory = CataCombo.Text,
taskDate = calander.SelectedDate.Value
};
taskList.Add(newTask);
MainWindow main = Owner as MainWindow;
main.taskListBox.ItemsSource = taskList;
titletxBx.Clear();
prioritytxBx.Clear();
DesctxBx.Clear();
responsibilitytxBx.Clear();
}
private void finishBtn_Click(object sender, RoutedEventArgs e)
{
this.Close();
}
}
}
You need to save the TaskList somewhere, make the tasklist definition public to get acces from the main window and pass it from the main window when you load the new form:
observableCollection<Task> AllTasks = new ObservableCollection<Task>();
public ObservableCollection<Task> taskList = new ObservableCollection<Task>();
public NewTaskWindow(ObservableCollection<Task> taskList)
{
InitializeComponent();
this.tasklist = tasklist
}
After that, you only need to retrieve and send it from the main to the new window
private void addTaskBtn_Click(object sender, RoutedEventArgs e)
{
NewTaskWindow newTaskWindow = new NewTaskWindow(tasklist);
newTaskWindow.Owner = this;
newTaskWindow.Show();
tasklist = newTaskWindow.tasklist;
}
In the main window you must initialize it for the first run if not you will get an error:
ObservableCollection<Task> taskList = new ObservableCollection<Task>();
public MainWindow()
{
InitializeComponent();
}
....
Obviously this only save for the time you have the program open, when you close the program it will lose all the info. So if you are interested in that also, save in a file and load from it.

I get confused with Form.Close()

So I link delegate from Form2 to This_Hide() fuction in Form1, then i link delegate from Form3 to delegate in Form2(which link to function in Form1 as I said) but I get confused that it still work although Form2 is CLOSED when I making instance of Form3. If Form.Close() method closes Form2 and dispose it how delegate from Form3 can still call function(delegate) from Form2..?
namespace TestingMachine
{
public delegate void FxDelegate();
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
Form2 fr2 = new Form2();
fr2.Delegate_Father_Hide = new FxDelegate(This_Hide);
fr2.Show();
}
public void This_Hide()
{
this.Hide();
}
}
}
namespace TestingMachine
{
public partial class Form2 : Form
{
public FxDelegate Delegate_Father_Hide;
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
Form3 fr3 = new Form3();
fr3.Delegate_Hide_Grandfather = new FxDelegate(Hide_Grandfather);
fr3.Show();
this.Close();
}
public void Hide_Grandfather()
{
Delegate_Father_Hide();
}
}
}
namespace TestingMachine
{
public partial class Form3 : Form
{
public FxDelegate Delegate_Hide_Grandfather;
public Form3()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Delegate_Hide_Grandfather();
}
}
}

Cannot set the value of a global variable

Im pretty new to programming, but im very eager to get more into this stuff, and in particular, c#. I have a made some code for an autotyper (spam bot if i may), only to be used as a goal for me to create. Essentially, what i want the program to do, is as following:
When i start my Form1, the global variable "_timerValue" is set to
1000
When i hit Start button, the text from the textbox on will be sent at
the interval of "_timerValue"
When i hit the Speed button, Form2 will show.
When i hit very fast, "_timerValue" is set to 5000 (testing purposes)
Form1 code:
public partial class Form1 : Form
{
static class TimerIntervalValue
{
Form2 f2 = new Form2();
TimerIntervalValue = f2._timerValue;
}
public Form1()
{
InitializeComponent();
f2._timerValue = "1000";
}
public void timer1_Tick(object sender, EventArgs e)
{
SendKeys.Send(textBox1.Text);
}
private void button1_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
}
private void button1_MouseDown(object sender, MouseEventArgs e)
{
MessageBox.Show(f2._timerValue);
timer1.Interval = Convert.ToInt32(f2._timerValue);
if (timer1.Enabled == false)
{
timer1.Enabled = true;
textBox1.Enabled = false;
button1.Text = ("Stop");
}
else if (timer1.Enabled == true)
{
timer1.Enabled = false;
textBox1.Enabled = true;
button1.Text = ("Start");
}
}
private void button2_Click(object sender, EventArgs e)
{
Form2 form2 = new Form2();
form2.Show();
}
}
Form2 code:
public partial class Form2 : Form
{
public string TimerValue;
public string _timerValue
{
get { return TimerValue; }
set { TimerValue = value; }
}
public Form2()
{
InitializeComponent();
}
public void button1_Click(object sender, EventArgs e)
{
Form2 frm2 = new Form2();
frm2._timerValue = "5000";
}
}
I originally tried to create a Form2 instance just under "InitializeComponent();" in Form1, but that didnt seem to be accessible through the other funtions.
I just know its something very simple like im using the wrong class to create the Form2 instance or something like that ...
Anyway, thank you in advance
Just mark TimerValue and _timerValue as static. Then you don't need to use
Form2 f2 = new Form2(); or Form2 frm2 = new Form2();
anymore. In Form 1, just use Form2._timerValue instead of f2._timerValue. In Form 2, just change:
public void button1_Click(object sender, EventArgs e)
{
_timerValue = "5000";
}

Access Form1 controls from Form2

Have two forms-Form1 & Form2.Form1 has a button(btnNew),which opens Form2 on click, and is disabled.I need to enable the button again, only when Form2 is closed.User needs to use Form1 also simultaneously.This code is not enabling the button again. Where am I missing.
In Form1:
private void btnNew_Click_1(object sender, EventArgs e)
{
Form2 f2 = new Form2();
f2.Show();
btnNew.Enabled = false;
}
public void EnableButton()
{
btnNew.Enabled = true;
}
In Form2:
private void Form2_FormClosing(object sender, FormClosingEventArgs e)
{
Form1 f1 = new Form1();
f1.EnableButton();
}
You code creates a new Form1 which will be different from the one already running in your application.
You could try adding a reference to Form1 in your Form2 and operate on it's controls that way.
Give form2 a property like:
public Form ParentForm {get; set;}
And assign it form1 in your button click:
Form2 f2 = new Form2()
f2.ParentForm = this;
f2.show();
Then in your closing you should be able to do something like:
this.ParentForm.EnableButton();
Subscribe to your Form2 closing event from within the class that is instantiating it (Form1).
private void btnNew_Click_1(object sender, EventArgs e)
{
Form2 f2 = new Form2();
f2.Closing += f2_Closing;
f2.Show();
btnNew.Enabled = false;
}
public void f2_Closing(object sender, FormClosingEventArgs e)
{
this.EnableButton();
}
public void EnableButton()
{
btnNew.Enabled = true;
}
