Web Control Events

Evolutility provides 2 server events:

DBChange raised when a record is Inserted, Updated or Deleted.
CredentialChange raised when the user logs in or out.

DBChange

DatabaseEventArgs:

Action (DBAction) action performed by the database (Insert, Update, or Delete).
ID - (Integer) record primary key.

Custom code in the page nesting the control can be triggered by the web control doing an action to the database. Here is a code sample to display the last database action in a label.

protected void Evo1_DBChange(object sender, Evolutility.WebControls.UIServer.DatabaseEventArgs e)
{

Label1.Text = string.Format("DB: {0} #{1}", e.Action.ToString(), e.ID);

}

VB.net

Protected Sub Evo1_DBChange(ByVal sender As Object, ByVal e As Evolutility.UIServer.DatabaseEventArgs) Handles Evo1.DBChange

Label1.Text = "DB: " & e.Action.ToString & " #" & e.ID

End Sub

CredentialChange

CredentialEventArgs:

Action (CredentialAction)
UserID (Integer)
UserName (String)
DBApplicationKey (String)
Description (String)

Custom code in the page nesting the control can be triggered by the user logs in or out. Here is a code sample to log these in a label.

Evo1_CredentialChange(object sender, Evolutility.WebControls.UIServer.CredentialEventArgs e)
{

Label1.Text = string.Format("Cred.: {0} #{1} {2}", e.Action, e.UserID, e.UserName);

}

VB.net

Protected Sub Evo1_CredentialChange(ByVal sender As Object, ByVal e As Evolutility.UIServer.CredentialEventArgs) Handles Evo1.CredentialChange

Label1.Text = "Cred.: " & e.Action.ToString & " #" & e.UserID & " " & e.UserName

End Sub
