I have a pictureBox and I want to perform a some statement when the image is clicked, So how can i check when the pictureBox is selected inside an if statement ?
Add an event handler to the MouseClick event, and then add in the code you want to run within the handler method:
MyPictureBox.MouseClick += new MouseEventHandler(MyEventHandler);
private void MyEventHandler(object sender, MouseEventArgs e)
{
//your code here
}

I want write a program that :
In textbox type a picturebox name and in other textbox type location number,then press button to move that picturebox that name is equal textbox1 to that location.
my question is how I can send a object(picturebox) to a Function?
If I understand you correctly you want to move a picture box by entering its name into a textbox? Then this is a possibility:
private void button_click(object sender, EventArgs e)
{
string pBoxName = textbox1.Text;
// I don't quite understand what you mean by 'location number'
int newPos = int.Parse(textbox2.Text);
// boxList is a List<PictureBox>
PictureBox pBox = boxList.Where(x => x.Name.Equals(pBoxName)).FirstOrDefault();
if(pBox != null)
{
MoveTheBox(pBox, newPos);
}
}
private void MoveTheBox(PictureBox box, int newPos)
{
// move the box
}

I'm building a program with C# in Windows Forms, and the following question came to me. I have several buttons in my form and when any of them is clicked, I want to be able to store its ID in a single variable that will handle only one ID at a time. I already have a method that does this, but the fact is I don't want to call this method from the event handler of each button:
button1_Click(object senders /* ... yada yada ... */)
Is there a way how I can simplify this with a single method? Is it even possible?
You don't need many Click event handlers for your buttons, just 1 is enough:
private void buttons_Click(object sender, EventArgs e){
Button button = sender as Button;
//do something with the clicked button
//...
}

In my project, I need to get the listview containing the data from the back end, If I place the listview in the form and upon clicking a button I can load data, but the requirement is initially the listview should be hidden or not present there, only on clicking the button the listview should be viewed with data. Thank you.
Set the List View's property Visible = Falsein the properity window.
Within the button click event handler set it to true;
listView1.Visible = true;
You use the Visible Property. At the form load, you set it to false and then in the button_click
private void button1_Click(object sender, EventArgs e)
{
listView1.Visible = true;
}
I think You should use listView1.Hide(); initially in Form constructor
And on button click You should use listView1.show()

Im wondering how to make my textbox format "DD.MM.YYYY" that after load form the textbox will be filled with "__ .__ .__" and those spaces and dots cannot be deleted. Is there any way to do that?
Thanks
Why don't you use a MaskedTextbox? Use the following as mask, you can set the mask either at design time or at form load.
private void Form1_Load(object sender, EventArgs e)
{
maskedTextBox1.Mask = "00.00.0000";
}
You would probably be looking at something like Ajax Masked Edit
Another way to do it would be to use a jquery plugin
You could use a MaskedTextbox that will do exactly what you describe. A DateTimePicker might be better though...
