Property Value

Type Description

The name of a JavaScript function used to handle the CustomizeToolbox event.


The CustomizeToolbox event enables you to customize the Web Report Designer’s Toolbox.

The handler function receives two parameters: the first parameter is the client-side Report Designer (the event sender) and the second parameter is an object with the following property:

  • ControlsFactory
    Contains information about all controls available in the Toolbox.

The following client-side event handler function hides the Label control in the End User Designer Toolbox:

window.ReportingDesignerCustomization = {
    onCustomizeToolbox: function (s, e) {
      var labelInfo = e.ControlsFactory.getControlInfo("XRLabel");
      labelInfo.isToolboxItem = false;

To register a custom control, use the *ControlsFactory.registerControl method. This method accepts the following parameters: the control name and the object that stores information about a custom toolbox item.
