Why doesn't AutoSize property in Windows Form TextBox appear in IntelliSense
Solution 1
The AutoSize property for TextBox is always true, forced by the constructor. The property is hidden in the parent class (TextBoxBase) to avoid accidentally setting it to false. It has [Browsable(false)] to hide it in the property grid, [EditorBrowsable(EditorBrowsableState.Never)] to hide it in the IntelliSense popup window. You can change it however:
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
textBox1.AutoSize = false;
textBox1.Height += 10;
}
}
Yes, doesn't look great. Now you know why it is hidden.
Solution 2
The Control.AutoSize
property (and its override in TextBoxBase
) is declared with the following attribute:
[EditorBrowsable(EditorBrowsableState.Never)]
IntelliSense uses this property to decide not to show the property in the completions list.
(I don't know enough about Windows Forms to say why this property is marked not browsable.)

According into the specs (http://msdn.microsoft.com/en-us/library/k63c05yf.aspx)
Textboxes in Windows Forms should have an
autosize
property.And it actually doesn't break when you type in
TextBox1.AutoSize = true
. However, it doesn't seem to appear in the list of IntelliSense properties.Why is this?
I have tried recompiling and it all compiles, but the
textbox.autosize
property never appears. -

Cody Gray about 13 years@stickman: The reason is because textboxes automatically resize themselves, based on the height of the font face and font size. Like Hans says, you can change the height of the textbox manually, but it looks funny because there's a bunch of empty space.
