Toolbox Data("The Details View control is used to display a single record from a data source in a table, where each field of the record is displayed in a row of the table.
Note: The Details View control can provide support for update, delete, insert, and paging operations with other types of data sources; however, you must provide the implementation for these operations in an appropriate event handler. Clicking the Update button updates the record in the data source, while clicking the Cancel button abandons any changes. You can customize the appearance of the Details View control by setting the style properties for different parts of the control.
I need to set focus to a textbox inthis template after post back because the List View is in a longscrolling div.
Without setting focus the user needs to scroll down thediv after postback to get to the item.
However, to make use of the Details View control's advanced capabilities you must explicitly declare the row fields to include in the Details View control. The row fields specified are added to the Details View. Note: Explicitly declared row fields can be displayed in combination with automatically generated row fields. For more information, see Validation Server Controls. The Details View control can automatically add a Command Field row field with an Edit, Delete, or New button by setting the Details View. Unlike the Delete button (which deletes the selected record immediately), when the Edit or New button is clicked, the Details View control goes into edit or insert mode, respectively. Validation server controls are also provided to assess user input. Auto Generate Insert Button properties to true, respectively. When the Details View control is bound to a data source control, the Details View control can take advantage of the data source control's capabilities and provide automatic updating, deleting, inserting, and paging functionality. Input controls that are appropriate for the field's data type (such as a Text Box or a Check Box control) are displayed with a field's value for the user to modify. The Details View control provides built-in capabilities that allow the user to update, delete, insert, and page through items in the control. In edit mode, the Edit button is replaced with an Update and a Cancel button.The second lesson in this chapter demonstrates how you can bind to data to allow users to interact with it.The lesson covers using web server controls such as Grid View, Repeater, Details View, and many more., in the past there was a lot of attempt to allow the users to insert data through Header or Footer Template which is no longer required.In this post I will show you the full data editing capabilities of and code.The Details View control recognizes buttons with the Button. When this property is set, the data rows are displayed in bands, alternating between the Details View. Command Name property set to "Edit", "Update", "Delete", "New", "Insert", or "Cancel"; however, you still must provide the functionality yourself.
