User Control - Custom Properties
It is very simple, just add a property:
public string Value {
get { return textBox1.Text; }
set { textBox1.Text = value; }
}
Using the Text property is a bit trickier, the UserControl class intentionally hides it. You'll need to override the attributes to put it back in working order:
[Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Bindable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public override string Text {
get { return textBox1.Text; }
set { textBox1.Text = value; }
}
You do this via attributes on the properties, like this:
[Description("Test text displayed in the textbox"),Category("Data")]
public string Text {
get => myInnerTextBox.Text;
set => myInnerTextBox.Text = value;
}
The category is the heading under which the property will appear in the Visual Studio Properties box. Here's a more complete MSDN reference, including a list of categories.
Just add public properties to the user control.
You can add [Category("MyCategory")]
and [Description("A property that controls the wossname")]
attributes to make it nicer, but as long as it's a public property it should show up in the property panel.
