The following article demonstrates the usage of the DataBound server-side event of the RadTreeMap.
The DataBound server-side event of the RadTreeMap is fired once the control is fully data-bound. This event only occurs if the items are loaded from a data source (the DataSource or DataSourceID property is set).
The DataBound event handler receives two arguments:
The RadTreeMap that is loading items. This argument is of type object, but can be cast to the RadTreeMap type.
An EventArgs object.
