internal handlers for these events. The default handler retrieves the commands defined by the bound data source to process and execute these operations.Figure 4Note: you do not need to write code after you mark the grid display or update data. In more complex cases, you may need to write some code. Figure 5 gridview and DataGrid The data source control and the gridview control are usually used to bind data without code.

support direct creation of images and PDF documents and related operations. This means that when an application calls a dynamically created menu image containing the anti-aliased text, or needs to export a page in Acrobat format, PHP will be an ideal technology to solve this problem. Although these functions can also be obtained theoretically through other technologies competing with PHP, other technologies often require third-party custom components

. 7. Why do you fetch all grid view rows from the server for every single gridview update?This will be addressed in Beta. Treeview: 1.

when an application calls a dynamically created menu image containing the anti-aliased text, or needs to export a page in Acrobat format, PHP will be an ideal technology to solve this problem. Although these functions can also be obtained theoretically through other technologies competing with PHP, other technologies often require third-party custom components to be installed. Another point that makes PHP the best choice for writing server scripts is
