Mvc gridview9/18/2023 ![]() ![]() Add a Button Web control beneath the GridView, setting its ID to DeleteSelectedProducts and its Text property to Delete Selected Products. Let s also add the user interface for deleting the selected products. Also configure the GridView to support paging by checking the Enable Paging checkbox from the smart tag. Configure the UnitPrice BoundField so that its value is formatted as a currency. Like we did in the previous tutorial, remove all but the ProductName, CategoryName, and UnitPrice BoundFields, and change the HeaderText properties to Product, Category, and Price. įigure 2: Create a New ObjectDataSource Named ProductsDataSource ( Click to view full-size image)įigure 3: Configure the ObjectDataSource to Retrieve Data Using the GetProducts() Method ( Click to view full-size image)įigure 4: Set the Drop-Down Lists in the UPDATE, INSERT, and DELETE Tabs to (None) ( Click to view full-size image)Īfter completing the Configure Data Source wizard, Visual Studio will automatically create BoundColumns and a CheckBoxColumn for the product-related data fields. ![]() Since this GridView will be read-only, set the drop-down lists in the UPDATE, INSERT, and DELETE tabs to (None). Configure the ObjectDataSource to use the ProductsBLL class, calling the GetProducts() method to return the data. Next, choose to bind the GridView to a new ObjectDataSource named ProductsDataSource.

Our example will include a paged GridView listing the products in the Products database table with a checkbox in each row (see Figure 1). In particular, we'll build an example that closely mimics the web-based email client user interface. In this tutorial we will see how to add a column of checkboxes and how to determine what checkboxes were checked on postback. The user can select an arbitrary number of messages and then perform some action, such as moving the emails to another folder or deleting them. Web-based email clients, for example, typically display the list of messages with a column of checkboxes. At times, however, we may want to allow the user to pick an arbitrary number of items from the grid. A column of radio buttons is a suitable user interface when the user is limited to choosing at most one item from the grid. In the preceding tutorial we examined how to add a column of radio buttons to the GridView for the purpose of selecting a particular record. ![]() This tutorial looks at how to add a column of check boxes to a GridView control to provide the user with an intuitive way of selecting multiple rows of the GridView. ![]()
