Question

I’m a beginner in C# and reading about data binding. My book introduces with the starting code like this:

// Create object (width, text, color)

TextParms tp = new TextParms(200, "Casablanca", Color.Beige);

// Bind text and BackColor properties of control

txtMovie.DataBindings.Add("Text", tp, "Tb_Text"); // line 2

What does line 2 actually do? Where did the parameters Text and Tb_Text come from? What are their uses?

Answer 1

txtMovie.DataBindings.Add("Text", tp, "Tb_Text")

Looking at the documentation of Binding

public Binding(
    string propertyName,
    Object dataSource,
    string dataMember
)

• Text is a property of probably your txtMovie object
• datasource in your tp is the source of your databinding
• Tb_Text is a datamember of your TextParams class.
