TemplateInstanceAttribute.Instances Property

The TemplateInstance enumeration value that the current template instance represents.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

public TemplateInstance Instances { get; }

The possible values are either the Single field or the Multiple field.

The following code example demonstrates how to use the Instances property. In the Page_Load event of an ASPX page, the MyLoginViewA custom control's TemplateInstanceAttribute class for the AnonymousTemplate property is queried.

For the definition of MyLoginViewA control, see TemplateInstanceAttribute.


protected void Page_Load(object sender, EventArgs e)
{

  // Get the class type for which to access metadata.
  Type clsType = typeof(MyLoginViewA);
  // Get the PropertyInfo object for FirstTemplate.
  PropertyInfo pInfo = clsType.GetProperty("AnonymousTemplate");
  // See if the TemplateInstanceAttribute is defined for this property.
  bool isDef = Attribute.IsDefined(pInfo, typeof(TemplateInstanceAttribute));

  // Display the result if the attribute exists.
  if (isDef)
  {
    TemplateInstanceAttribute tia =
      (TemplateInstanceAttribute)Attribute.GetCustomAttribute(pInfo, typeof(TemplateInstanceAttribute));
    Response.Write("The <AnonymousTemplate> has the TemplateInstanceAttribute = " + tia.Instances.ToString() + ".<br />");
    if (tia.IsDefaultAttribute())
      Response.Write("The TemplateInstanceAttribute used is the same as the default instance.");
    else
      Response.Write("The TemplateInstanceAttribute used is not the same as the default instance.");
  }

}
