************counting the checked checkboxes with in a datalist**************
you can iterate throug items and check the values and add then in array.

ArrayList arr = new ArrayList();
foreach(DataListItem item in dataList1.Items)
{
CheckBox chk = (CheckBox)item.FindControl("CheckBox",CheckBox);
if(chk != null)
{
if(chk.Checked == true)

Code snippet:

For example, I only want to change the colour of a cell, if that cell is in the "Status" column, and the the cell contains "Fault".

Example DataTable with Three columns: "Order", "Status", and "Notes"

Using the following handler:
Protected Sub HandleOnItemDataBound(ByVal sender As System.Object, ByVal e As DataGridItemEventArgs)

If instr(e.Item.Cells(0).Text,"FAULT",CompareMethod.Text) > 0 Then
e.Item.BackColor = System.Drawing.Color.Red
End If

End Sub

JavaScript History
• Java was born as “LiveScript” at the beginning of the
94’s.
• Name changed into JavaScript (name owned by
Netscape)
• Microsoft responds with Vbscript
• Microsoft introduces JScript (dialect of Javascript)
• A standard is defined: ECMAScript (ECMA-262,
ISO-16262)

Objects
Object: A data structure with methods;
a special method is the “constructor”.
function Rectangle(w, h) {
this.width=w;

a=new Rectangle(3,4); a.area() => 12 a.width => 3

Objects
Actually, JavaScript does NOT have classes and inheritance.
Moreover, the approach we have shown is not the most
efficient in terms of memory allocation.
It would be better to use the “prototype” feature, which can
be consideres a STATIC object
Rectangle.prototype.area=function(){return this.w*this.h}

Arrays
a = new Array()
a[0]=3; a[1]=“hello”; a[10]=new Rectangle(2,2);

a[“name”]=“Jaric”

Java-JavaScript interaction: JSObject
JSObject allows Java to manipulate objects that are defined in JavaScript.
Values passed from Java to JavaScript are converted as follows:
JSObject is converted to the original JavaScript object.
Any other Java object is converted to a JavaScript wrapper, which can be
used to access methods and fields of the Java object.
Converting this wrapper to a string will call the toString method on the
original object, converting to a number will call the floatValue method if
possible and fail otherwise.
Converting to a boolean will try to call the booleanValue method in the
same way.
Java arrays are wrapped with a JavaScript object that understands
array.length and array[index].
A Java boolean is converted to a JavaScript boolean.
Java byte, char, short, int, long, float, and double are converted to
JavaScript numbers.
Note If you call a Java method from JavaScript, this conversion happens
automatically--you can pass in "int" argument and it works.

Java-JavaScript interaction: JSObject
Values passed from JavaScript to Java are converted as follows:
Objects that are wrappers around Java objects are unwrapped.
Other objects are wrapped with a JSObject.
Strings, numbers, and booleans are converted to String, Float, and
Boolean objects respectively.
Examples
(String) window.getMember("name")
(JSObject) window.getMember("document")
