User Control - Custom Properties

Question

I have developed a User Control in Visual Studio  WinForms C   and have a question   I need the user of my User Control to be able to change certain string values and I would like them to be able to add the user control to their Form and click on it to bring up the Properties Pane where my User Control s custom properties will be displayed   How can I have my own custom properties for my user control  For example   My user control contains a TextBox  and I would like the user to be able to change the value of that TextBox via a property named  Text  or  Value  in the properties at Design-Time

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.

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

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
