+ * TActiveRepeater class
+ *
+ * TActiveRepeater represents a data bound and updatable grid control which is the
+ * active counterpart to the original {@link TRepeater} control.
+ *
+ * This component can be used in the same way as the regular datagrid, the only
+ * difference is that the active repeater uses callbacks instead of postbacks
+ * for interaction.
+ *
+ * Please refer to the original documentation of the regular counterparts for usage.
