Combobox implements text and value

Combobox must have text and value ~

Steps:

1. Set the data source for combobox ~

ComboBox1.DataSource = list;

List is the data source you want to give to comboBox.

 

2. Set the text value for comboxBox: comboBox1.DisplayMember = "name"; // all the name field attributes in the set are text

 

3. Set the value of the header comboxBox: comboBox1.ValueMember = "id"; // the attribute of all id fields in the set is value
My list is a generic set ~

List <User> list = new List <User> ();

// Test Data

List. Add (new User (1, "qq "));

List. Add (new User (2, "bb "));

My User class is the following code (remember to set get method)

Public class User

{

Private int id;

Public int Id

{

Get {return id ;}

Set {id = value ;}

}

Private string name;

Public string Name

{

Get {return name ;}

Set {name = value ;}

}

Public User (){}

Public User (int id, string name)

{This. Id = id;

This. Name = name;

}

}
The following describes how to obtain text and value.

Get value MessageBox. Show (comboBox1.SelectedValue. ToString ());

Get text MessageBox. Show (comboBox1.Text );
