Examples

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.");
  }

}

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
  
  ' Get the class type for which to access metadata.
  Dim clsType As Type = GetType(MyLoginViewA)
  ' Get the PropertyInfo object for FirstTemplate.
  Dim pInfo As PropertyInfo = clsType.GetProperty("AnonymousTemplate")
  ' See if the TemplateInstanceAttribute is defined for this property.
  Dim isDef As Boolean = Attribute.IsDefined(pInfo, GetType(TemplateContainerAttribute))
  
  ' Display the result if the attribute exists.
  If isDef Then
    Dim tia As TemplateInstanceAttribute = CType(Attribute.GetCustomAttribute(pInfo, GetType(TemplateInstanceAttribute)), TemplateInstanceAttribute)
    Response.Write("The <AnonymousTemplate> has the TemplateInstanceAttribute = " & tia.Instances.ToString() & ".<br />")
    If (tia.IsDefaultAttribute()) Then
      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.")
    End If

  End If

End Sub

Remarks

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