ASP.NET Server controls can be disclosed and initiated by server events, which can be handled by page developers. Page developers can achieve this by connecting events to the controls in a declarative manner (indicating the attribute name of the event network, and the attribute value indicates the method name to be called).

Note that the web form page frame is always executed on the server, even if the verification has been performed on the client. This helps prevent users from avoiding verification by simulating another user or pre-approved transaction. Enable client authentication by default. If the client can, the upper verification will be automatically performed. To disable client authentication, set the clientTarget property of the page to "Downlevel" to force the client verification).

Assign the defaultView attribute included in the DataSet into the name of the table that wants to use within the DataSet. The DEFAULTVIEW property represents the current state of a table in the DataSet, including any changes made by the application code (for example, row deletion or value change).

MyDataGrid.dataSource = ds.tables ["authors"]. Defaultview; mydatagrid.database ();

MyDataGrid.dataSource = DS; mydatagrid.datamember = "authors"; mydatagrid.database ();

SqlDataAdapter maintains a parameter collection that can be used to replace variable identifiers ("@" before the name. Add a name, type, and size of the name, type, and size of the specified parameters, and set it to the selected value. Mycommand.selectcommand.parameters.add (New SqlParameter ("@ State", Sqldbtype.nvarchar, 2)); MyCommand.selectCommand.Parameters ["@ State"]. Value = MySelect.Value;

Do you use MyCommand in both PUB programs?

Hello, please forgive me, when you mistaken, you have a lot of valuable time. Your resume, we have studied carefully, and it is impeccable whether it is from the technology or from individual integrity.

Repeater has no built-in layout or style. All HTML layouts, format settings, and style tags in the template of the control must be explicitly declared. For example, if you want to create a list in the HTML table, you need to declare the

tag in Headertemplate, the table line in ItemPlate ( tag,
tag and data binding item) and Tag.

***************************************

You can customize the sorting behavior of the grid by creating the column collection and processing Sortexpression for each column. (For automatically generated columns, SortExpression is the same as the data field.) Ignore SortExpression on a column will disable sort by this column. You can also create the sort button of the Outlook style using TemplateColumn. Note that this button must also specify "Sort" CommandName. In addition, it must pass the sort field as a Commandargument.

Server end comment syntax: <% - Note -%>

Server Note Enables page developers to prevent server code (including server controls) and static content execution or presentation. The following example illustrates how to prevent content and send to the client. Note that the content between <% - and -%> will be filtered, which is only visible in the original server file, even in which other ASP.NET instructions are included.

***************************************

If you double-click the DataGrid button to make positive and reverse sorting? ? ?
