Label Control

The Label is one of the simplest and most used controls. It displays text that users can't edit.

What is a Label?

Labels display static text. They're used to describe other controls, show information, or act as headers. Users cannot edit label text directly.

Common uses: Field names (First Name:), headers, status messages, instructions.

Code Example

// Set label text
lblName.Text = "Enter your name:";

// Change label text dynamically
lblStatus.Text = "Loading...";
lblStatus.ForeColor = Color.Blue;

// Update label after operation
private void btnSave_Click(object sender, EventArgs e)
{
    // ... save logic ...
    lblStatus.Text = "Saved successfully!";
    lblStatus.ForeColor = Color.Green;
}

// Use mnemonic (Alt + key to focus)
lblName.Text = "&Name:";  // Alt+N focuses the TextBox
lblName.UseMnemonic = true;
