Calling public method of user control from a parent form

I have form containing a Clear Button, usercontrol. The userControl has some text box and labels.

On the click of clear button the entries in the textbox should get cleared.

I have written a public method in userControl class which clears entries on from text box.

How to call this clear() method from clicking clear button from parent form?

Solution

  • your Clear() method should be something like this

    //this method in the userControl
public void Clear()
{
   //Clear your text box
   this.txtbox1.Text = string.Empty;
   //Do other clean-up things if you want
}

    now in your parent form, use your userControl name (you must add the userControl to your parent form) and call this code upon clicking the button event

    private void button1_Click(object sender, EventArgs e)
{
   //Call the Clear method from the UserControl
   yourUserControlName.Clear();
}

    otherwise, please share your code.
