Property Value

Type: System.Web.UI.TemplateInstance

A TemplateInstance enumeration value that the current template instance represents.

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.");
  }

}
