First, we have to very be clear in our mind that there are mainly two ways of taking the cell value from the Grid View: This code is for taking the value apart from the Grid View events; that is, any common event using a sender object.But ensure that the control/link is inside the Grid View, only then can we cast sender as Grid View.
INITIAL CHAMBER Step 1: Open Visual Studio 2010 and create an empty website. Step 2: In Solution Explorer you will get your empty website. By following these steps: For Web Form gridview_demo (Your Empty Website) - Right Click, Add New Item, then Web Form. For SQL Server Database gridview_demo (Your Empty Website) - Right Click, Add New Item, then SQL Server Database. DATABASE CHAMBER Step 3: Go to your Database [Database.mdf], we will create a table - tbl_Data. Design your table like the following: Table - tbl_data [Don’t forget to make ID - Identity Specification - Yes] Figure 1: Database DESIGN CHAMBER Step 5: Now Open your gridview_file, where we create our design for binding and performing edit, delete, and update operation with dropdownlist. I hope the above information was a little bit helpful for you, kindly let me know your valuable feedback or thoughts.This tutorial starts with a look at how the Roles framework associates a user's roles with his security context.This code is a bit complex but just add it knowing that we may refer to it in the future.Here in Grid View, in the beginning the major part is to make the decision of putting either a bound field or a template field and the answer is simple: When we want to place any control inside the Grid View then we can go for template field, otherwise bound field will be simpler.It then examines how to apply role-based URL authorization rules. When using forms authentication, an authentication ticket is used as an identity token.
Following that, we will look at using declarative and programmatic means for altering the data displayed and the functionality offered by an ASP. As we discussed in the method will be called on every request to a page that is protected by the role-based URL authorization rules.If the user's browser does not support cookies, or if their cookies are deleted or lost, somehow, it's no big deal – the Note Microsoft's Patterns & Practices group discourages using persistent role cache cookies.Since possession of the role cache cookie is sufficient to prove role membership, if a hacker can somehow gain access to a valid user's cookie he can impersonate that user.Anyone could visit this page, but only authenticated users could view the files' contents and only Tito could delete the files.Applying authorization rules on a user-by-user basis can grow into a bookkeeping nightmare.URL authorization rules can specify roles instead of users.
