private void

frm ListBox_Load( object sender, EventArgs e)

{ listBox1.Item s.Clear();

for ( int i = 0; i < 10; i+ + ) listBox1.Item s.Add( "Item " + i);

}

ListBox

A nd W e can use A ddR ange m ethod to add data:

private void frm ListBox_Load(object sender, EventArgs e)

{

string[] strArr = new string[] { "Tèo","Tí","Bin","Bo"};

listBox1.Item s.AddRange(strArr);

}

{ private string m _strID ;

private string m _strN am e;

public C S tudent( string strID ,

string strN am e) { this m _strID = strID ;

this m _strN am e = strN am e;

}

public string ID

{ get { return this m _strID ; }

set { this m _strID = value ; }

}

public string N am e

{ get { return this m _strN am e; }

set { this m _strN am e = value ; }

}

}

ArrayList arr = new ArrayList ();

for ( int i= 0;i< 10;i+ + )

{arr.Add( new CStudent ( "ID _" + i, "N am e " + i));

}

listBox1.D ataSource = arr;

listBox1.ValueM em ber = "ID " ;

listBox1.D isplayM em ber = "N am e" ;

A lso W e can use D ataSource to display data

To get object from Listbox, W e could use coding below :

if (listBox1.SelectedItem != null )

{

CStudent svTeo = ( CStudent )

listBox1.SelectedItem ; lblM essage.Text = aStudent.N am e

+ " W as selected" ; }

U se Item s to add data

private void frm CheckListBox_Load

(object sender, EventArgs e)

{ chklbLeft.Item s.Add("Tèo"); chklbLeft.Item s.Add("Tí");

chklbLeft.Item s.Add("Bin");

chklbLeft.Item s.Add("Bo");

}

O r w e could use A ddR ange

chklbLeft.Items.AddRange(new string[] { "Tèo","Tí","Bin","Bo"});

H ow to process Item s C hecked ???

H ow to process Item s C hecked ???

H ow to process Item s C hecked ???

C ase 3:

for (int i = 0; i < chklbLeft.Item s.Count; i+ + ){

if (chklbLeft.G etItem C hecked(i))

{

//Process Item checked here

}

}

G o back C hecklistB ox Exam ple:

private void btnAdd_Click

(object sender, EventArgs e)

foreach ( string s in chklbRight.Item s)

{chklbLeft.Item s.Rem ove(s);}

}

private void btnAddAll_Click

( object sender, EventArgs e)

{ chklbRight.Item s.AddRange

(chklbLeft.Item s); chklbLeft.Item s.Clear();

}

private void btnRem ove_Click

(object sender, EventArgs e)

{

foreach (string s in chklbRight.CheckedItem s)

chklbLeft.Item s.Add(s);

foreach(string s in chklbLeft.Item s)

chklbRight.Item s.Rem ove(s);

}

private void btnRem oveAll_Click

( object sender, EventArgs e)

Menu (2 ways to use)

Property

I would like to tell you : using MainMenu is the basic Menu.

In this case, I will demo add Menu at Runtime for you

Please see next slide !
