ASP.NET Web Forms   Web Forms Server Controls   Web Forms User Controls

---

Once you have created a user control and specified properties on that control, you can change those property values both declaratively and programmatically. For example, in the user control defined in Creating a User Control, you can change the values of the UserID and Password properties.

• Declare the property name and a value as an attribute/value pair in the user control tag. In the following example, if UserID represents the text property of a text box control contained in the myCtrls:Login user control, the default value for the property is declaratively set to "Enter ID here:".

<myCtrls:Login id="myLogin" UserID="Enter ID here:" Runat="server" />

• You can manipulate property control values by creating event-handling code. For more information, see Defining Web Forms Event-Handling Methods.
