Asp.net listview item control instance

Asp tutorial. net listview item control instance
The following figure shows the design of the form. A LIstView control is placed on the form, an ImageList (ImageSize (50, 40) control is placed, and the largeImageList attribute of listView is selected as ImageList, then, place a TabControl control.
When I Load the form, I run the following code to add an item to the listview:

For (int I = 0; I <14; I ++)
{
ListViewItem lvi = new ListViewItem ();
Lvi. Text = DateTime. Now. AddDays (I). ToString ("MM dd ");
Lvi. ToolTipText = dt initial display time. AddDays (I). ToString ("yyyy-MM-dd ");
Lsv reservation status. Items. Add (lvi );
}

This is the re-drawing code.
 

Private void listviewincludrawitem (object sender, DrawListViewItemEventArgs e)
{
Rectangle rect = e. Bounds;
Rect. Width = rect. Width-3;
If (e. State & ListViewItemStates. Selected )! = 0)
{
// Change the selected background color
E. Graphics. FillRectangle (new SolidBrush (Color. FromArgb (215,232,252), rect );
// Draw a border
E. Graphics. DrawRectangle (new Pen (Color. FromArgb (125,162,206), rect );
}
Else
{
// Default background color
Using (SolidBrush bBrush = new SolidBrush (Color. White ))
{
E. Graphics. FillRectangle (bBrush, rect );
// Draw a border
E. Graphics. DrawRectangle (new Pen (Color. FromArgb (125,162,206), rect );
}
}
If (ListView) sender). View! = View. Details)
{
Font ft = new System. Drawing. Font (FontFamily. GenericSansSerif, 9 );
SolidBrush fontbrush = new SolidBrush (Color. Blue );
StringFormat Format = new StringFormat ();
Format. Alignment = StringAlignment. Center;
E. graphics. drawString (e. item. text, ft, fontbrush, new RectangleF (rect. left, rect. top + 10, rect. width, rect. height), Format );
Ft. Dispose ();
Fontbrush. Dispose ();
}
