I have developed an ASP.NET application. In it there is one message alert label. The problem is how to see the number of unread messages in the label control using local storage.

Thanks

you mean, when the user login, he/she should able to see the number of unread messages in that label?

yes
   
Which unread messages? Please provide details and post some code as well.

First of all you should have a count of unread messages to show the user the number of unread messages; once you have got that count, you can simply display that count to the user. So, the easiest way to do is to have another column in your table of messages just to keep record for that message in case that message has been read or not; that column can be a simple boolean value. In case a user has read a message, the value against that message in database is set as true otherwise false. After that, you can get the count of all those messages where that boolean value is false and then you can display that count in that label.
   
(In Database)Create a row in the already existing table or create a new table for this...
have a primary key for each mail,(I hope that you already have that)....
have one row called "Message Status" in the table, whenever the mail has been recieved,
initially assign that "Message Status" value as 0(which means the message is yet to be read)
whenever the use clicks the respective message, update the "Message Status" as 1 (which means the mail has been read) likewise, whenever the user login, count the number of "Message Status" having 0 value and give that value in the respective label you need.
