Inherited properties

Name Type Inherited from Description
displayType Accessor ReadOnly string ContentDataProvider Display type used to format content
getContentDescriptor undefined ContentDataProvider Get the content descriptor.
imodel Accessor IModelConnection ContentDataProvider IModel to pull data from
keys Accessor KeySet ContentDataProvider Keys defining what to request content for
pagingSize Accessor number | undefined ContentDataProvider Paging options for obtaining content.

Presentation data providers, when used with paging, have ability to save one backend request for size / count. That
can only be achieved when pagingSize property is set on the data provider and it's value matches size which is used when
requesting content. To help developers notice this problem, data provider emits a warning similar to this:
<br>ContentDataProvider.pagingSize doesn't match pageOptions in ContentDataProvider.getContent call. Make sure you set provider's pagingSize to avoid excessive backend requests.<br>
To fix the issue, developers should make sure the page size used for requesting data is also set for the data provider:
TS<br>const pageSize = 10;<br>const provider = new ContentDataProvider(imodel, rulesetId, displayType);<br>provider.pagingSize = pageSize;<br>// only one backend request is made for the two following requests:<br>provider.getContentSetSize();<br>provider.getContent({ start: 0, size: pageSize });<br>
rulesetId Accessor string ContentDataProvider Id of the ruleset to use when requesting content
selectionInfo Accessor SelectionInfo ContentDataProvider Information about selection event that results in content change
