# how to access my form's panel in my class

I have a [form](https://www.mindstick.com/forum/6/multi-form-mfc-application) and in the form I have a [panel](https://www.mindstick.com/blog/11988/restructuring-corporate-offenses-government-appointed-panel-suggests-in-house-adjudication-system) [named](https://answers.mindstick.com/qa/44918/what-is-a-no-day-yet-named-motion) : mypanel

[now](https://yourviews.mindstick.com/view/81402/it-s-liberals-vs-progressives-in-us-politics-now) I want to write a [class](https://www.mindstick.com/blog/165/generic-class-in-c-sharp) and in this class I want to use this:

```
foreach (Control cont in mypanel.Controls)        {            // do sth        }but it is impossible, please help me how to access my form's panel in my classI use this code :foreach (Control cont in mypanel.Controls)            {                if (cont is PictureBox)                {                    string path = @"" + Application.StartupPath + "\\Image\\";                    cont.BackgroundImage = Image.FromFile(path + Rnd.Next(7).ToString() + ".png");                }            }

Hi Mark,

Check if the type of control is Panel and cast it.

```
foreach (Control cont in mypanel.Controls){    if(cont is Panel)    {        Panel myPanel
= (Panel)cont;       
MessageBox.Show(myPanel.Name);    }}
```

You need to cast the control into PictureBox since not all control contains the specific property you want to set,

PictureBox pBox = (PictureBox)cont;

pBox.BackgroundImage = Image.FromFile(path + Rnd.Next(7).ToString() + ".png");
