Reference type passing ListView presentation data

Summary of teacher scoring project

Create a SE employee class

1.1//Analyze the project first

* 01. I need to display information about three employees in a ListView control

* Then you can define a 3-length array to host the data you want to display

* 02. Through analysis, we will define such an array

* se[] emps=new se[3];

* 03. Write a method: Assign a value to each item in the array

* 04. Bind the data in the array to the ListView, without traversing to an item in the array,

* form a row in the ListView

Se[] Emps=new se[2];

1.2//write a method to insert data into an SE object array

Public void LoadData ()

{

Emps[0]=new SE ();

Emps[0].id = "001";

Emps[0]. Name = "Bruce Lee";

Emps[0]. age = 15;

EMPS[1] = new SE ();

Emps[1].id = "002";

EMPS[1]. Name = "Cheng Long";

EMPS[1]. age = 15;

}

1.3//write a method that binds the data in the array to the ListView to form a row

Public void Fromarraytolistview ()

{

foreach (SE emp in Emps)

{

Each iteration of an item in the array constitutes a row on the interface

ListViewItem lvitem=new ListViewItem (emp.id);

LVITEM.SUBITEMS.ADD (EMP. Name);

LVITEM.SUBITEMS.ADD (EMP. Age.tostring ());

LVITEM.SUBITEMS.ADD (EMP. Assess);

LVITEM.SUBITEMS.ADD (EMP. Score.tostring ());

LVSHOW.ITEMS.ADD (Lvitem);

}

}

1.4//Double click on the mouse event

private void Lvshow_doubleclick (object sender, EventArgs e)

{

Get the employee selected by the user

Double-click the list interface to bring up the selected employee's information

Frmscore frm=new Frmscore ();

Frm.myitem = Lvshow.selecteditems[0];

frm. Show ();

}

Public ListViewItem myitem;

private void Frmscore_load (object sender, EventArgs e)

{

Txtname.text=myitem. SUBITEMS[1]. Text;

Txtassess.text = myitem. SUBITEMS[3]. Text;

Txtscore.text = myitem. SUBITEMS[4]. Text;

}

1.5//Assign the value in the text box to the MyItem object

private void Btnok_click (object sender, EventArgs e)

{

myitem. SUBITEMS[1]. Text = txtName.Text;

myitem. SUBITEMS[3]. Text = Txtassess.text;

myitem. SUBITEMS[4]. Text = Txtscore.text;

}
