Gridview rowupdating newvalues oldvalues
The database is part of the project and it will be automatically mounted by VS.You can change this easily be creating your own database and changing the connection string in the web config.Still I will let you discover them and invent new ones.We are going to make our row editable on double click and in order to achieve that we will write down a function (in Java Script) that is going to be associated to the grids client side event called Row Dbl Click. At first we will add in our ASPX file, inside the grid definition a new section that is called Client Side Events (as we already did for other controls) and it will look like: It is that simple!We need to attach the following method to the Row Updating event: What happens in this event is that a request for updating rows is sent.
public static bool Remove Import(int credit Card Id, int year, byte month) public static bool Add Import(int credit Card Id, int year, byte month, decimal import) public static bool Update Import(int credit Card Id, int year, byte month, decimal import) This is it.In case the user hits Escape key (27) we will just get out of the edit mode by calling Cancel Edit method.Once Update Edit is called a callback will be generated and the Row Updating server side method will be executed, in which we will need to handle the persistence of the data.If you run the example right now and double click on a row, you should see something similar to this: Even if this looks nice and simple, you maybe noticed that the fields are not editable.This is because we didn’t binded our grid to a valid and well defined Data Source.
In this post we will continue adding functionality on our previous example.
