You can either declare Public Property in User control

CSS

Public string MyProperty {get;set;}

and access it like

CSS

myUserControl.MyPorperty="something";

where myUserControl is instance of you User Control

or if it is just for once

declare it in your constructor like

CSS

public partial class MyUserControl : UserControl
{
     public MyUserControl(string myString)
     {
         //use myString
     }
}

and initialise you User Control like

CSS

MyUserControl myUserControl = new MyUserControl("someting");

Solution 3

Where do I put myControl.MyProperty = "string Value"; ? What "parent" are you refering to?

Solution 2

Create a property inside your user control, and assign this value from the parent form.
for example

inside the control
public string MyProprty {get;set;}

inside the parent 
myControl.MyProperty = "string Value";

i did this to show if it is working,
UserControl1 usr = new UserControl1();
usr.MyProprty = "Boom";
MessageBox.Show(usr.MyProprty + "");
yea it's working.
but if i add a messagebox inside my usercontrol .
like this.
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show(MyProprty+"");
}
popping up an empty box -_- idk what to do.

Solution 1

Define public properties for the user control. Then the form can pass values by setting these properties.
