Raise an Event Except when something happpen

Scenario: Only If the user follow the path Click on ListView > Click on Button the Button1 do something.
In other word I want to check in Button1_Click(object sender, EventArgs e) if the previous focus was on ListView.
So I tried this:
private void ListView_Test_Leave(object sender, EventArgs e)
{
_focusedControl = null;
}
I want raise previous event except when this event is raised:
private void Button1_Click(object sender, EventArgs e)
{
if(_focusedControl == listView_Test)
{
// ...
}
}
Edit: I have a variable that holds a reference to the currently focused control:
private Control _focusedControl;
and I update it in this way:
private void ListView_Test_GotFocus(object sender, EventArgs e)
{
_focusedControl = (Control)sender;
}
If the user follow the path Click on ListView > Click on Button I want raise only the Button1_Click event, in all other case I want normal raise.

You could use a helper variable.
bool wasRaised=false;
private void Button1_Click(object sender, EventArgs e) { wasRaised=true;}
Then you can check that variable in your event, and only run if it is false.

redirection from one user control to another user control

I have a usercontrol.ascx in a aspx page. And in my user control I have a button click event, and I need to open another user control from this button click. Please give me some suggestions on how to achieve this.
Thanks.

You can use Visible property. Let's call the user control with the button ucControl1 and the other ucControl2.
// code-behind of ucControl1
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
ucControl2.Visible = false;
}
protected void btn_Click(object sender, EventArgs e)
{
ucControl2.Visible = true;
}

add click event to many control

I have many controls in my form. for example 120 labels in one panel. and i want when user clicked on each label just call same function with same parameter.
Now i used like this :
private void label67_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
private void label66_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
private void label65_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
private void label64_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}
now can i make easy way to call ChangeToTextbox function when user clicked in any label?

Add the same OnClick handler for all labels on the panel:
private void Form1_Load(object sender, EventArgs e)
{
panel1.Controls.OfType<Label>().ToList().ForEach(l => l.Click += label_Click);
}
private void label_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}

Find all your controls then just add the handler via code;
List<Control> controls = GetAllMyControls();
foreach(Control control in controls)
{
control.OnClick += (o, e) => { ChangeToTextBox(o); }
}
The syntax should be very similar for both web and winform solutions.

It can be easily achieved by using following approach: Pls give a try,
1) Go to Windows Forms Designer and click the first Label control to select it. Then hold down the CTRL key while you click each of the other labels to select them. Be sure that every label is selected.
2) Then go to the Events page in the Properties window. Scroll down to the Click event, and type label_Click in the box
3) Press ENTER. The IDE adds a Click event handler called label_Click() to the code, and hooks it to each of the labels.
private void label_Click(object sender, EventArgs e)
{
ChangeToTextbox(sender);
}

How to perform Label click in C#?

I have a label working as a button. I would like when I press a button the click event to this label to take action. for example
private void Label1_Click(object sender, EventArgs e)
{
MessageBox.Show("I pressed this label and showed me this messagebox");
}
Now I want when I press this button, the label1 click event to be performed
private void button1_Click(object sender, EventArgs e)
{
// I want when I press this button something like this happens
Label1.PerformClick();
}

private void button1_Click(object sender, EventArgs e)
{
Label1_Click(sender, e);
}
now if you want to show a message of which control was clicked all in one method do the following
private void label1_Click(object sender, EventArgs e)
{
Control control = (Control)sender;
var name = control.Name;
MessageBox.Show(string.Format("I pressed this {0} and showed me this messagebox",name));
}

Two ways to do this.
First:
private void button1_Click(object sender, EventArgs e)
{
Label1_Click(sender, e); // Just call the Label's click handler
}
Second:
// Bind the Label1_Click handler to the button1 Click event, as they both use the same delegate
button1.Click += new EventHandler(Label1_Click);
With the second approach, note that in C# delegates are multi-cast, so both the button1_Click handler and the Label1_Click handler will be called when the button is clicked, in the order they were bound.

private void button1_Click(object sender, EventArgs e)
{
//What the label click do:
MessageBox.Show("I pressed this label and showed me this messagebox");
}
Is that not easier?
Why do you want to do it ?

I think it would be easier for you to just include the lable click functionality with the button click. Maybe even separate each piece in their own method and call them from the button click. Here is how you'd call another click event.
private void button1_Click(object sender, EventArgs e)
{
label1_Click(sender, e);
}

public class MyLabel:Label
{
public void PerformClick()
{
OnClick(new EventArgs());//InvokeOnClick(this,new EventArgs());
}
}

How can I navigate and pass data between Pages?

I'm a bit of a beginner with this so i'll try and keep it simple.
I have a a xaml page with a button click event linking it to another xaml page. What I'm trying to do is on the click event take two strings and pass them to a text box on the second page. Can you please show me a simple code example of how to do this?

On the button click event of the first page you do something like the following
private void button1_Click(object sender, RoutedEventArgs e)
{
string urlWIthData = string.Format("/Page2.xaml?name={0}", txtName.Text);
this.NavigationService.Navigate(new Uri(urlWIthData, UriKind.Relative));
}
On the desintation page, you do the following:
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
myTextBox.Text = this.NavigationContext.QueryString["name"].ToString();
}
