Asp net objectdatasource updating
Namely, there is a Typed Data Set named folder that has a single Data Table/Table Adapter.
We need to add two new methods to the Table Adapter that, when invoked, will call the appropriate stored procedure.
In this tutorial we'll see how to map an Object Data Source's Insert(), Update(), and Delete() methods to the methods of BLL classes, as well as how to configure the Grid View, Details View, and Form View controls to provide data modification capabilities.
Over the past several tutorials we've examined how to display data in an ASP.
Perform these steps twice: once to create a method named stored procedure and returns tabular data.
For a detailed discussion on creating and working with Typed Data Sets, see Creating a Data Access Layer (VB) (C#).
Get Employees Subset By Department IDSorted ( @Department ID int, @sort Expression nvarchar(50), @start Row Index int, @maximum Rows int ) AS IF @Department ID IS NULL -- If @Department ID is null, then we want to get all employees EXEC dbo. Department ID = ' CONVERT(nvarchar(10), @Department ID) ' ) as Emp Info WHERE Row Num BETWEEN ' CONVERT(nvarchar(10), @start Row Index) ' AND (' CONVERT(nvarchar(10), @start Row Index) ' ' CONVERT(nvarchar(10), @maximum Rows) ') - 1' -- Execute the SQL query EXEC sp_executesql @sql END check allows for a user interface where the visitor can opt to view all employees or narrow down the results to a specific department. NET 2.0 with SQL Server 2005, when implementing custom paging we must provide a method that, when invoked, returns the precise number of records being paged through.
Get Employees Subset Sorted @sort Expression, @start Row Index, @maximum Rows ELSE BEGIN -- Otherwise we want to get just those employees in the specified department IF LEN(@sort Expression) = 0 SET @sort Expression = 'Employee ID' -- Since @start Row Index is zero-based in the data Web control, but one-based w/ROW_NUMBER(), increment SET @start Row Index = @start Row Index 1 -- Issue query DECLARE @sql nvarchar(4000) SET @sql = 'SELECT Employee ID, Last Name, First Name, Department ID, Salary, Hire Date, Department Name FROM (SELECT Employee ID, Last Name, First Name, e. Name as Department Name, ROW_NUMBER() OVER(ORDER BY ' @sort Expression ') as Row Num FROM Employees e INNER JOIN Departments d ON e. This information is used by the data Web control in rendering the paging interface.
With custom paging, the data Web control hands over its paging responsibilities to us, the page developer.

To add a method to the Table Adapter, right-click on the Table Adapter in the Data Set Designer and choose Add Query from the context menu.
Choose to "Use exsiting stored procedure", select the stored procedure to invoke, indicate the type of data it returns, and then provide a name for the Table Adapter's method.
