Question

I have a SplitContainer, and in its right panel I have a Form. I want to retrieve the values of the TextBoxes of the form when I click on a button outside the Form, but inside the panel. How to do it?

Answer 1

May be you are having a UserControl in the Right panel of the SplitContainer.

In you that userControl class write a public method to get values.

public string GetValueOfTheTextBox()
{
    return textBox.Text;
}

Add the userControl the SplitContainer.

MyUserControl myUserControl = new MyUserControl();
//Add this to the splitContainer right panel.

From out side of the MyUserControl class you can call GetValueOfTheTextBox method.

string text = myUserControl.GetValueOfTheTextBox();
