The ListView control is a new data presentation control that was added to .Net 3.5 , you may wonder why its added to the framework , and what it provide .
The ListView control was added to provide The following functionalities :
- A very flexible and customizable layout.
- A built in data paging support with the DataPager control.
- support data grouping ( repeating items) .
- Built in support for deleting,inserting,paging,sorting,and updating the data.
Now , to compare the ListView control with the dataList,GridView and repeater control , lets look at the table below :
|Supported Funcationalities |
|Control||Paging||Data Grouping||Provide Flexible Layout||Update,Delete||Insert||Sorting|
| GridView||supported||Not supported||Not Supported||supported||Not Supported||supported|
|DataList||Not supported||supported||supported||supported||Not supported||Not supported|
|Repeater||Not supported||Not supported||supported||Not supported||Not supported||Not supported|
The GridView : it supports paging but it doesn't provide a flexible layout , since its mainly used to display the data in a table based layout.And If we looked at data inserting , the Gridview doesn't have a built in support for inserting data( since it doesn't call the insert method of it underlying data source when you click on a button with a CommadName set to "Insert" ).
The DataList : it support data grouping ( through its RepeatColumns property) , but it doesn't have a built in support for paging,inserting ,deleting , updating the data. and if you looked at its laout , you will find that by default the datalist renders as html table and you will have to set its flowLayout to "Flow" to stop that behaviour.
The Repeater control : you will find that it provides a flexible layout but it doesn't support data grouping ,inserting,deleting , updating and paging through the data .
The ListView control was added to provide a rich data control that can support all the required functionalities at the same time , so now you can easily display a fully customizable layout that supports Grouping,paging , inserting , deleting , updating and sorting the data.
The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs,
googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.
The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
