The ComboBox in WinForm sets both the text and value methods

The ComboBox in WinForm cannot be set to the same value as the DropDownList control in the WebForm property, and can be implemented by writing a new class.

1, first add a new class ComboBoxItem in Form1:

public class ComboBoxItem
{
private string _text=null;
Private Object _value=null;
public string Text{get{return this._text;} set{this._text=value;}}
public object Value{get {return this._value;} Set{this._value=value;}}
public override string ToString ()
{
return this._text;
}
}

2. Add in the Form1_Load function:

ComboBoxItem newitem = new ComboBoxItem ();
NewItem. Text = "ABC";
NewItem. Value = "1";
COMBOBOX1.ITEMS.ADD (NewItem);

3. Add in ComboBox1_SelectedIndexChanged:

ComboBoxItem myitem = (comboboxitem) Combobox1.items[combobox1.selectedindex];
MessageBox.Show (MyItem.Value.ToString ());

You can see the output effect!!!

Upstairs, I also used it in the project.
