Example

The following example demonstrates how to perform a drill-down in ASPxDashboard on the client side.

In this example, the ASPxClientDashboard.PerformDrillDown method is used to perform a drill-down for a specified row in a Grid dashboard item. The dxSelectBox widget contains categories for which a drill-down can be performed. These categories are obtained using the ASPxClientDashboard.GetAvailableDrillDownValues method. Select a required category and click the Perform Drill-Down button to perform a drill-down by the selected category.

When the Grid displays a list of products (the bottom-most detail level), you can only perform a drill-up action that returns you to the top detail level. The ASPxClientDashboard.PerformDrillUp method is called to do this.
