Gridview rowupdating not giving new values
Now, create a class named Person BAL3 into App_Code folder by right clicking it and write respective methods for calling Insert, Delete, Update and Load methods of Data Access Layer class file (Person DAL3) (In my case I have a 3-Tier folder inside App_Code folder, you can directly add inside App_Code or you can create a separate project for BAL and add reference of this project into your Presentation Layer). In the above method, I am instantiating Person BAL3 and calling the Update method by p[assing required parameters.
I am not goint into details of how I am connecting database and manipulating the data just to make this tutorials short. Code to Update records Above method will fire when Update link will be clicked for a particular row of the Grid View in edit mode.
For this demo application, I have taken a very simple example. 1) Fix for the code block For the css 'pre', add new property 'min-width: 730px;' and add width nn percentage.
I am assuming that I have to play with record of persons (First Name, Last Name, Age) and I will refer only these data through out this article. just to give you flexibility to not show scroll bar for long screens.
Lets create a form that will have three textboxes for First Name, Last Name and Age.
Now we have to write our Presentation Layer that will use our Business Access Layer methods.
To list the record into Grid View that will also enable us to Edit, Delete record, copy paste following code.
Dispalying Records into Grid View Create a file called and create a Grid View something like displayed into the picture.
May I request you to post it in the Questions section of this website? A little hint in order to solve your problem is "30-8-2008 " is not a correct Date Time format (try to convert or parse it to Date Time and you will get error). tulsi When you will use Sql Data Source, you are writing your select query, connectionstring and other stuffs at the page itself.
Is Valid method just to check if correct data has been entered.
In the above code, first I am validating the page by using Page.
Here, I have assumed that you will create the respective stored procedure yourself into the database or you may download attachment from using System; using System. In this case definitely the passing number of variable will not be good idea.
As we don't have any business logic here so simply instantiate the Person DAL3 class of DAL and call methods. Now we have all set to go, now just run your project and try inserting records.
