Binds the value of an ASP.NET Profile property to a parameter object.

Remarks

You can use the ProfileParameter class to bind the value of an ASP.NET Profile parameter to a parameter used in a parameterized SQL query, business object method, or filtering expression.

The ProfileParameter class provides the PropertyName property in addition to those inherited from the Parameter class. The PropertyName property identifies the ASP.NET Profile property from which the ProfileParameter retrieves a value.

Note

Controls that bind data to the parameter might throw an exception if a ProfileParameter object is specified but no corresponding profile property is set. Similarly, they might display no data if the profile property is set with null. Set the DefaultValue property to avoid these situations where appropriate.

Constructors

ProfileParameter()	Initializes a new instance of the ProfileParameter class.
ProfileParameter(ProfileParameter)	Initializes a new instance of the ProfileParameter class with the values of the instance specified by the `original` parameter.
ProfileParameter(String, DbType, String)	Initializes a new instance of the ProfileParameter class, using the specified property name to identify which ASP.NET Profile property to bind to.
ProfileParameter(String, String)	Initializes a new named instance of the ProfileParameter class, using the specified property name to identify which ASP.NET Profile property to bind to.
ProfileParameter(String, TypeCode, String)	Initializes a new named and strongly typed instance of the ProfileParameter class, using the specified property name to identify which ASP.NET Profile property to bind to.

Properties

ConvertEmptyStringToNull	Gets or sets a value indicating whether the value that the Parameter object is bound to should be converted to `null` if it is Empty. (Inherited from Parameter)
DbType	Gets or sets the database type of the parameter. (Inherited from Parameter)
DefaultValue	Specifies a default value for the parameter, should the value that the parameter is bound to be uninitialized when the Evaluate(HttpContext, Control) method is called. (Inherited from Parameter)
Direction	Indicates whether the Parameter object is used to bind a value to a control, or the control can be used to change the value. (Inherited from Parameter)
IsTrackingViewState	Gets a value indicating whether the Parameter object is saving changes to its view state. (Inherited from Parameter)
Name	Gets or sets the name of the parameter. (Inherited from Parameter)
PropertyName	Gets or sets the name of the ASP.NET Profile property that the parameter binds to.
Size	Gets or sets the size of the parameter. (Inherited from Parameter)
Type	Gets or sets the type of the parameter. (Inherited from Parameter)
ViewState	Gets a dictionary of state information that allows you to save and restore the view state of a Parameter object across multiple requests for the same page. (Inherited from Parameter)

Methods

Clone()	Returns a duplicate of the current ProfileParameter instance.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
Evaluate(HttpContext, Control)	Updates and returns the value of the ProfileParameter object.
GetDatabaseType()	Gets the DbType value that is equivalent to the CLR type of the current Parameter instance. (Inherited from Parameter)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
LoadViewState(Object)	Restores the data source view's previously saved view state. (Inherited from Parameter)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnParameterChanged()	Calls the OnParametersChanged(EventArgs) method of the ParameterCollection collection that contains the Parameter object. (Inherited from Parameter)
SaveViewState()	Saves the changes to the Parameter object's view state since the time the page was posted back to the server. (Inherited from Parameter)
SetDirty()	Marks the Parameter object so its state will be recorded in view state. (Inherited from Parameter)
ToString()	Converts the value of this instance to its equivalent string representation. (Inherited from Parameter)
TrackViewState()	Causes the Parameter object to track changes to its view state so they can be stored in the control's ViewState object and persisted across requests for the same page. (Inherited from Parameter)

Explicit Interface Implementations

ICloneable.Clone()	Returns a duplicate of the current Parameter instance. (Inherited from Parameter)
IStateManager.IsTrackingViewState	Gets a value indicating whether the Parameter object is saving changes to its view state. (Inherited from Parameter)
IStateManager.LoadViewState(Object)	Restores the data source view's previously saved view state. (Inherited from Parameter)
IStateManager.SaveViewState()	Saves the changes to the Parameter object's view state since the time the page was posted back to the server. (Inherited from Parameter)
IStateManager.TrackViewState()	Causes the Parameter object to track changes to its view state so they can be stored in the control's ViewState object and persisted across requests for the same page. (Inherited from Parameter)
