C# creating a property in a Usercontrol

Question

I have a project in C# and created a usercontrol with two components: a combobox and a button. I need to create a property to change the properties of the usercontrol combobox.

I tried it this way:

 public ComboBox Combo
 {
     get
     {
        return cboLista;
     }
     set
     {
        value = cboLista;
     }
  }

The property appears, I can make the changes in control but it does not volley and when I run the application the settings of the combobox do not work.

Answer 1

Syntax error I believe: Inverts the Set cboLista and value and take the tests!

public ComboBox Combo
{
    get
    {
       return cboLista;
    }
    set
    {
       cboLista = value;
    }
}

Good a hint when doing this should concern you with methods and actions and so your usercontrol should have these features programmed. When I used this in Web I programmed some actions that I was going to use usercontrol.

Reinforcing what I said the programming should go to the object and then you should use Usercontrol as reference for some settings, I’ll leave an example:

The event Resize, we can configure the size of the combo according to the size of the UserControl dynamically in that way:

private void UCCombo_Resize(object sender, EventArgs e)
{
    Combo.Width = this.Size.Width - 11;
}

When placing the object (Usercontrol) it will automatically leave the combo size this way:

So, just to conclude, it can be dynamic, but the programming must be done on the Father object

Another example:

Create in your UserControl a code like that:

public ComboBoxStyle ComboSytle
{
    get
      {
          return comboBox1.DropDownStyle;
      }
    set
      {
         comboBox1.DropDownStyle = value;
      }
}

By placing the UserControl in his Form it will enable this image equal configuration below:

And changing the style control will change this new configuration as well.
