pass picture from usercontrol to Form

Question

I have a main form with 1 panel, the panel has 10 user controls and every user control has on picture box.

Main form:

private void Form1_Load(object sender, EventArgs e)    
{

    Picturebox1.Image=....

    for(int i=0;i<10;i++)
    {
        uscontrol a=new uscontrol()
        {
            usimage=Image.Fromfile....  
        };
        panel1.Controls.Add(a);
    }
}

User control:

public Image usimage
    {
        get { return imagebox.Image; }
        set { imagebox.Image = value; }
    }

How can I do that when I click on one of the user controls, it passes image of that user control to main form and shows it in Picturebox1, thank you.

Firstly, you will need to add MouseClickEvent to every uscontrol. To achieve that, edit your Form1_Load to this.

Picturebox1.Image=....
for(int i=0;i<10;i++)
{
    uscontrol a=new uscontrol()
    {
        usimage=Image.Fromfile....  
    };
    a.MouseClick += new MouseEventHandler(USControl_Clicked); //Note this added line 
    panel1.Controls.Add(a);
}

And then you will need to add USControl_Clicked to your From1 code.

private void USControl_Clicked(object sender, MouseEventArgs e)
{
    //Here we cast sender to your uscontrol class and access usimage
    Picturebox1.Image = (sender as uscontrol).usimage; 
}

pass picture from usercontrol to Form
