How to access controls that are inside a TabControl tab?

This is all I have so far.

tabControl1.TabPages[0].???

I have a PictureBox inside of TabPage1 of my TabControl.

How can I change the image location with code and not the properties pane?

Unless you've set GenerateMember to false on the picture box or you're building the form dynamically you should be able to reference the picture box by its name:

pictureBox1.ImageLocation = "...";

Otherwise, assuming the picture box is the first control in the first tab page you can use the Controls collection:

var picBox = (PictureBox) tabControl1.TabPages[0].Controls[0];
picBox.ImageLocation = "...";

If you know there is exactly one picture box somewhere but you're not sure what page it's on or where on that page it is you can use Linq:

var picBox = tabControl1.TabPages.Cast<Control>()
    .SelectMany(page => page.Controls.OfType<PictureBox>())
    .First();
picBox.ImageLocation = "...";

Although the controls appear inside a container (as a TabControl), they're all defined on the form, so there is no need to access them through the container.

Instead of:


tablControl1.TabPages[0].MyContainedControl...

Simply type:


MyContainedControl...
