LINQ

LINQDataSource Control

LINQDataSource Control

The LINQDataSource control can be used to UPDATE, INSERT, and DELETE data on the pages of an ASP.NET website. Because the LINQDataSource control uses dynamically produced instructions for such tasks, there is no need to specify SQL commands.

The control makes it simple for users to utilise LINQ in an ASP.NET web page by setting properties in the mark-up language. Because it can connect other ASP.NET options on a page to a data source, LINQDataSource is very similar to controls like SqlDataSource and ObjectDataSource. As a result, we'll need a database to demonstrate the LINQDataSource Control's numerous functions.

Before discussing the control's use in an ASP.NET web page form, open the Microsoft Visual Studio Toolbox and click and drag the LINQDataSource control to the ASP.NET website's.aspx page as shown below.


The next step is to set up LINQDataSource by choosing all of the employee track's columns.

Now, on the.aspx page, add a GridView Control and set up it as shown below. The GridView control is robust and provides a lot of versatility when it comes to working with data. The control will appear in the browser shortly after it has been configured.


INSERT, UPDATE, and DELETE data in ASP.NET Page using LINQ

After thoroughly accomplishing all of the preceding steps, select LINQDataSource Tasks from the LINQDataSource Control and check all three boxes for enabling insertion, enable update, and enable delete, as seen in the screenshot below.

Because there are several rows and sections, you should add a Complete Detail or Master control below the Grid View control on your.aspx form to display only the details of a chosen row of the grid. Select the Depth Display Tasks checkboxes from the Detail View control, as shown below.

Simply save your changes and hit Ctrl F5 to return to the page in your browser, where you may now delete, alter, or insert any record on the detail view control.
