Without Using Visible how can you hide a user control?

Move it offscreen or set its size to (0,0).

Set a location (x, y) beyond the screen. Lets say, if your screen is 1280x1024, set (x, y) to (1600, 0).

Best,

But check the Screens property as well, you may be moving it onto the second monitor.

Can anyone tell me how exactly does this "this.Left" method work in conjunction with a form or user control?

It returns the x coordinate of the control's left edge.

Gets or sets the distance, in pixels, between the left edge of the control and the left edge of its container's client area.

Seems pretty straight forward to me

It basically gives the distance of the left edge of your control to the left edge of the container e.g. form,panel etc on which your control is lying.

It's not a method at all. It is a property (a pair of methods in this case). You can use ildasm.exe to understand how it works exactly. It returns a value of the "x" field of the control when you get it. And it calls SetBounds(...) method when you set it.

So your problem, if I understand correctly, is that you need to attach an integer to a combo box item. This is pretty easy:

private class MyComboBoxItem
{
    public readonly string Text;
    public readonly int Value

    public MyComboBoxItem(string text, int value)
    {
        this.Text = text;
        this.Value = value;
    }

    public override string ToString()
    {
        return this.Text;
    }
}

// Code to add the "France" item to the combo box
MyComboBoxItem france = new MyComboBoxItem("France", 5);
myComboBox.Items.Add(france);

// The event handler that handles selection changed event.
void myComboBox_SelectedValueChanged(object sender, EventArgs e)
{
    MyComboBoxItem selectedItem = (MyComboBoxItem)myComboBox.SelectedItem;
    int value = selectedItem.Value;
}

You can use ComboBox.Text for the text to display and its ComboBox.SelectedValue.

In binding, you can use DispalyMember for text display and ValueMember for the corresponding value.

There are so many ways...are you planning on storing the images in a database? Search SQL images on this site, it should point you in the right direction.
