A signature of a method consists of:
The formal parameters are inside the method parenthesis. Examples include:
Unlike delegates in C#, the return type IS NOT part of a method’s signature. Return types include void or one type of data object such as int, string, array and so on.
If the return type is not void, the method must include the return keyword followed by a value that is of the data object declared as the return type.
Example:
private double MileageCost(int miles, double rate)
{
return miles * rate;
}
This example will illustrate how to write one event handler to multiple objects. This example utilizes the checkbox objects. In the app, the user has an option to check up to four checkboxes. Each time he checks one, the total dollar value for each item the user is checking is displayed on a label.
An alternative would have been to place the code inside a button object. This would also provide the total in dollars for the checkboxes checked but not until the button was pressed. This application illustrates running totals based on check box clicks.
Two files are attached. A flash movie file illustrating the steps and a zip file containing the code. I recommend you oOpen the .swf file in a new window.
This code here demonstrates the 4 things, populating an array. Assigning the values of the array to a data source and binding the array. Lastly displaying the results on a web page. You can copy and paste the code to test it out.
