You can add a new property or update an existing property’s value in the dashboard definition. Custom properties are stored in the CustomProperties collection in a structured format. Each custom property in this collection contains the custom property’s unique name and value.
The following table lists the levels and corresponding properties used to access the collection at this level:
| Level to apply | Description | Property | Example |
|---|---|---|---|
| Dashboard | Stores custom data related to the dashboard. | Dashboard.CustomProperties | Dashboard description |
| Dashboard item | Stores custom data related to a particular dashboard item. | DashboardItem.CustomProperties | Chart Item - Scale Breaks |
| Chart Item - Constant Line | |||
| Data item container | Stores custom data related to the Grid’s columns, the Chart’s series and other elements of a dashboard item. | DataItemContainer.CustomProperties | Grid Item - Fixed (Pinned) Columns |
The code snippet below saves a new value for the DashboardDescription property:
designer.Dashboard.CustomProperties.SetValue("DashboardDescription", "New custom description");
designer.Dashboard.CustomProperties.SetValue("DashboardDescription", "New custom description")
The custom property’s value is stored as a string. For example, a dashboard XML file stores the DashboardDescription property at the dashboard’s level. The property’s value is used as the dashboard’s description.
<Dashboard>
...
<CustomProperties>
<DashboardDescription>This dashboard shows statistics on sales of bicycles, related equipment and accessories. ...</DashboardDescription>
</CustomProperties>
</Dashboard>
To clear a custom property value, pass null to the CustomProperties.SetValue method.
The following code snippet clears the value of the DashboardDescription property:
designer.Dashboard.CustomProperties.SetValue("DashboardDescription", null);
designer.Dashboard.CustomProperties.SetValue("DashboardDescription", Nothing)
Refer to the Create Custom Properties article for details.
