the query, it doesn t find a matching record with an employeeID of 0. This is an error condition, and an exception is thrown. You could solve this problem by revising the GetEmployee() method to return Nothing in this situation. However, it makes more sense to catch the binding attempt and explicitly cancel it when there s no employeeID parameter. You can do this by handling the ObjectDataSource.Selecting event and looking for the employeeID parameter in the ObjectDataSourceSelectingEventArgs.InputParameters collection, which has every parameter you re using indexed by name. Protected Sub sourceEmployee_Selecting(ByVal sender As Object, ByVal e As ObjectDataSourceSelectingEventArgs) If e.InputParameters("employeeID") Is Nothing Then e.Cancel = True End If End Sub This is the only code you need to write for the page. Figure 9-12 shows the page in action.

If the session times out because of inactivity By default, a session times out after 20 idle minutes If the programmer ends the session by calling SessionAbandon() In the first two cases, the session actually remains in memory, because the web server has no idea that the client has closed the browser or changed windows The session will linger in memory, remaining inaccessible, until it eventually expires In addition, session state will be lost when the application domain is re-created This process happens transparently when you update your web application or change a configuration setting The application domain may also be recycled periodically to ensure application health, as described in 18 If this behavior is causing a problem, you can store session state information out of process, as described in the next section.

Dynamically generate and display QR code Image in ASP . Net
5 Nov 2014 ... Here Mudassar Ahmed Khan has explained how to dynamically generate and display QR Code image using ASP . Net in C# and VB.Net.

The ObjectDataSource provides the same type of support for updatable data binding as the SqlDataSource. The first step is to specify the UpdateMethod, which needs to be a Public instance method in the same class: <asp:ObjectDataSource ID="sourceEmployees" runat="server" TypeName="DatabaseComponent.EmployeeDB" SelectMethod="GetEmployees" UpdateMethod="UpdateEmployee" /> The challenge is in making sure the UpdateMethod has the right signature. As with the SqlDataSource, updates, inserts, and deletes automatically receive a collection of parameters

Every control that supports repeated-value data binding includes a DataBind() method. You could call this method to bind a specific control. However, when you call the Page.DataBind() method, the page object calls DataBind() on every contained control, simplifying your life.

With out-of-process state storage, the session information is retained even when the application domain is shut down Table 6-4 describes the methods and properties of the HttpSessionState class..

from the linked data control. These parameters have the same names as the corresponding properties in the class. To understand how this works, it helps to consider a basic example. Assume you create a grid that shows a list of EmployeeDetails objects. You also add a column with edit links. When the user commits an edit, the GridView fills the ObjectDataSource.UpdateParameters collection with one parameter for each property of the EmployeeDetails class, including EmployeeID, FirstName, LastName, and TitleOfCourtesy. Then, the ObjectDataSource searches for a method named UpdateEmployee() in the EmployeeDB class. This method must have the same parameters, with the same names. That means this method is a match: Public Sub UpdateEmployee(ByVal employeeID As Integer, ByVal firstName As String, ByVal lastName As String, ByVal titleOfCourtesy As String) ... End Sub This method is not a match, because the names don t match exactly: Public Sub UpdateEmployee(ByVal id As Integer, ByVal first As String, ByVal last As String, ByVal titleOfCourtesy As String) ... End Sub This is not a match, because there s an additional parameter: Public Sub UpdateEmployee(ByVal employeeID As Integer, ByVal firstName As String, ByVal lastName As String, ByVal titleOfCourtesy As String, ByVal useOptimisticConcurrency As Boolean) ... End Sub The method matching algorithm is not case-sensitive, and it doesn t consider the order or data type of the parameters. It simply tries to find a method with the right number of parameters and the same names. As long as that method is present, the update can be committed automatically, without any custom code.
