Private Void TextChanged (Object Sender, System.EventArgs E)
{
/ / Method for distinguishing controls
String id = ((TextBox) sender .id;
// String B = ((Button) Sender ;commandname;
Switch (ID)
{
}
}
The WRAP attribute of TextBox decides whether it is automatically wrap.

Private void ImageButton1_click (Object Sender, System.Web.ui.ImageClicKeventargs E)
{
INT A = E.x;
INT b = E.Y;
// You can get the position of the mouse click, perform different operations.

This.button1.attributes.add ("onclick", "Return Upchang ();");
Function upchang ()
{
VAR i =
Document.form1.all ['ListBox1'].
SELECTEDINDEX; if (i> 0)
{
VAR VAL = Document.form1.all ['ListBox1'].
Item (i-1
.value;
Var txt = document.form1.all ['listbox1']. item
(i-1
.TEXT;
Document.form1.all ['ListBox1']. Item (i-1) .value = document.form1.all ['listbox1']. Item (i) .value;
Document.form1.all ['ListBox1']. Item (i-1) .text = document.form1.all ['listbox1']. item (i) .text;
Document.form1.all ['listbox1']. item (i) .value = val; document.form1.all ['listbox1']. Item (i) .text = txt;
Document.form1.all ['ListBox1']. SELECTEDINDEX = I-1;
}
}
