Here is a mostly clean attribute-based solution to the multiple submit button issue based heavily on the post and comments from Maarten Balliauw.
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class MultipleButtonAttribute : ActionNameSelectorAttribute
{
public string Name { get; set; }
public string Argument { get; set; }
public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
{
var isValidName = false;
var keyValue = string.Format("{0}:{1}", Name, Argument);
var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);
if (value != null)
{
controllerContext.Controller.ControllerContext.RouteData.Values[Name] = Argument;
isValidName = true;
}
return isValidName;
}
}
razor:
<form action="" method="post">
<input type="submit" value="Save" name="action:Save" />
<input type="submit" value="Cancel" name="action:Cancel" />
</form>
and controller:
[HttpPost]
[MultipleButton(Name = "action", Argument = "Save")]
public ActionResult Save(MessageModel mm) { ... }
[HttpPost]
[MultipleButton(Name = "action", Argument = "Cancel")]
public ActionResult Cancel(MessageModel mm) { ... }
Update: Razor pages looks to provide the same functionality out of the box. For new development, it may be preferable.
Storing "Simple" Repeating Patterns
For my PHP/MySQL based calendar, I wanted to store repeating/recurring event information as efficiently as possibly. I didn't want to have a large number of rows, and I wanted to easily lookup all events that would take place on a specific date.
The method below is great at storing repeating information that occurs at regular intervals, such as every day, every n days, every week, every month every year, etc etc. This includes every Tuesday and Thursday type patterns as well, because they are stored separately as every week starting on a Tuesday and every week starting on a Thursday.
Assuming I have two tables, one called events like this:
ID NAME
1 Sample Event
2 Another Event
And a table called events_meta like this:
ID event_id meta_key meta_value
1 1 repeat_start 1299132000
2 1 repeat_interval_1 432000
With repeat_start being a date with no time as a unix timestamp, and repeat_interval an amount in seconds between intervals (432000 is 5 days).
repeat_interval_1 goes with repeat_start of the ID 1. So if I have an event that repeats every Tuesday and every Thursday, the repeat_interval would be 604800 (7 days), and there would be 2 repeat_starts and 2 repeat_intervals. The table would look like this:
ID event_id meta_key meta_value
1 1 repeat_start 1298959200 -- This is for the Tuesday repeat
2 1 repeat_interval_1 604800
3 1 repeat_start 1299132000 -- This is for the Thursday repeat
4 1 repeat_interval_3 604800
5 2 repeat_start 1299132000
6 2 repeat_interval_5 1 -- Using 1 as a value gives us an event that only happens once
Then, if you have a calendar that loops through every day, grabbing the events for the day it's at, the query would look like this:
SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
RIGHT JOIN `events_meta` EM2 ON EM2.`meta_key` = CONCAT( 'repeat_interval_', EM1.`id` )
WHERE EM1.meta_key = 'repeat_start'
AND (
( CASE ( 1299132000 - EM1.`meta_value` )
WHEN 0
THEN 1
ELSE ( 1299132000 - EM1.`meta_value` )
END
) / EM2.`meta_value`
) = 1
LIMIT 0 , 30
Replacing {current_timestamp} with the unix timestamp for the current date (Minus the time, so the hour, minute and second values would be set to 0).
Hopefully this will help somebody else too!
Storing "Complex" Repeating Patterns
This method is better suited for storing complex patterns such as
Event A repeats every month on the 3rd of the month starting on March 3, 2011
or
Event A repeats Friday of the 2nd week of the month starting on March 11, 2011
I'd recommend combining this with the above system for the most flexibility. The tables for this should like like:
ID NAME
1 Sample Event
2 Another Event
And a table called events_meta like this:
ID event_id meta_key meta_value
1 1 repeat_start 1299132000 -- March 3rd, 2011
2 1 repeat_year_1 *
3 1 repeat_month_1 *
4 1 repeat_week_im_1 2
5 1 repeat_weekday_1 6
repeat_week_im represents the week of the current month, which could be between 1 and 5 potentially. repeat_weekday in the day of the week, 1-7.
Now assuming you are looping through the days/weeks to create a month view in your calendar, you could compose a query like this:
SELECT EV . *
FROM `events` AS EV
JOIN `events_meta` EM1 ON EM1.event_id = EV.id
AND EM1.meta_key = 'repeat_start'
LEFT JOIN `events_meta` EM2 ON EM2.meta_key = CONCAT( 'repeat_year_', EM1.id )
LEFT JOIN `events_meta` EM3 ON EM3.meta_key = CONCAT( 'repeat_month_', EM1.id )
LEFT JOIN `events_meta` EM4 ON EM4.meta_key = CONCAT( 'repeat_week_im_', EM1.id )
LEFT JOIN `events_meta` EM5 ON EM5.meta_key = CONCAT( 'repeat_weekday_', EM1.id )
WHERE (
EM2.meta_value =2011
OR EM2.meta_value = '*'
)
AND (
EM3.meta_value =4
OR EM3.meta_value = '*'
)
AND (
EM4.meta_value =2
OR EM4.meta_value = '*'
)
AND (
EM5.meta_value =6
OR EM5.meta_value = '*'
)
AND EM1.meta_value >= {current_timestamp}
LIMIT 0 , 30
This combined with the above method could be combined to cover most repeating/recurring event patterns. If I've missed anything please leave a comment.

Other option:
It uses jQuery and the same event object type. Fullcalendar supports a lot of hooks for customization too. I've added color coding based on tags and other features rather easily with it.
