Objectdatasource onupdating not firing seann william scott dating
When I finally resort to set the Update Method's parameter manually, everything works!This is a strong evidence of such a possible exception.NET is smart enough to do it for me automatically !! Supplement information: Upon clicking Edit Item Template's update link button: Item Command event is triggered, then return and goes no further. This is my foresaid work around solution: programmatically fill in datasource's parameters, when apparently ASP. However, I am still appreciate if anyone can explain this problem.Why isn't Form View's Item Updating event fired, when obviously link button's command name = "Update"? protected void Form View1_Item Command(object sender, Form View Command Event Args e) protected void Object Data Source1_Updating(object sender, Object Data Source Method Event Args e) protected void Object Data Source1_Inserting(object sender, Object Data Source Method Event Args e) private void set ODSParameter(Object Data Source Method Event Args e) Thanks for your suggestion, but I don't think it is a common practice to invoke ODS' update event manually.The following code example demonstrates how to use a Drop Down List control, Text Box controls, and several Object Data Source controls to update data. The Update method is invoked directly by the data-bound control instead.The Drop Down List displays the name of a Northwind employee, while the Text Box controls are used to enter and update address information. One piece of additional information: certain bind fields in the formview's edit template are optionally set to invisible during the course of editing.
Work around I am going to do: Programmatically fill in datasource's parameters and promatically invoke datasource's updating event. But I am so reluctant because with so many aspx I have written, I know ASP. Throw End Try End Try End Sub ' New Private ID As Object Public Read Only Property Emp ID() As Object Get Return ID End Get End Property Private a Last Name As String Public Write Only Property Last Name() As String Set a Last Name = value End Set End Property Private a First Name As String Public Write Only Property First Name() As String Set a First Name = value End Set End Property Public Read Only Property Full Name() As String Get Return a First Name & " " & a Last Name End Get End Property Private a Address As String Public Property Address() As String Get Return a Address End Get Set a Address = value End Set End Property Private a City As String Public Property City() As String Get Return a City End Get Set a City = value End Set End Property Private a Postal Code As String Public Property Postal Code() As String Get Return a Postal Code End Get Set a Postal Code = value End Set End Property Public Function Update() As Boolean ' Implement Update logic.

Close() Catch se As Sql Exception ' Log an event in the Application Event Log. The first code example demonstrates how to use a Drop Down List control, Text Box controls, and several Object Data Source objects to update data. Connection Strings("Northwind Connection") Dim conn As New Sql Connection(cts. For more information about parameter merging, object lifetime, and method resolution, see Update Method.
The second code example shows the class that is used in the first code example. Connection String) Dim sc As New Sql Command(" SELECT First Name, Last Name, Address, City, Postal Code " & _ " FROM Employees " & _ " WHERE Employee ID = @emp Id", conn) ' Add the employee ID parameter and set its value. When the Object Data Source control is associated with a data-bound control, such as the Grid View control, it is not necessary to call the Update method from page code. Connection Strings("Northwind Connection") Dim sds As New Sql Data Source(cts. Move Next() ' The IEnumerable contains Data Row View objects. Current, Data Row View) Dim id As String = row("Employee ID").

End Class ' Employee Logic Public Class Northwind Employee Public Sub New(an ID As Object) Me. You can handle the Updated event to examine any return values, output parameters, and exceptions, and to perform any post-processing.
