How to make WinForms UserControl fill the size of its container

Question

I am trying to create a multilayout main screen application. I have some buttons at the top that link to the main section of the application (e.g. management window for each entity in the Model)

Clicking any of these button displays the associated UserControl in a Panel. The Panel holds the UserControls that in turn holds the UI.

The WinForms UserControl does not have the Anchor or Dock property.

I have tried setting property of UserControl

AutoSize=True 

And

private void ManageUsersControl_Load(object sender, EventArgs e) {         this.Width = this.Parent.Width;         this.Height = this.Parent.Height; } 

But these did not work.
Note: I load this control dynamically at runtime

Answer 1

Try setting the Dock property to Fill:

private void ManageUsersControl_Load(object sender, EventArgs e) {         this.Dock = DockStyle.Fill; } 

I would also set AutoSize to the default, I believe is False. See how that works ...
