Thank you for writing.
You can handle the ItemDataBound
event, which is fired when the ListViewDataItem
is assigned an object from your data source. In the event handler, we can access the data-bound object properties and assign an image to the item. The following help article demonstrates a sample approach: https://docs.telerik.com/devtools/winforms/listview/populating-with-data/data-binding
Thus, you will assign the image just once to the data item. It is up to you how exactly you will store the image. It is just necessary to assign an Image instance to the data item.
I would kindly ask you to use our support-ticketing system for any further questions as it is the best way to reach the Telerik support. A post in the Forums doesn't guarantee you a response from a Telerik representative. You can discuss with the community your requirements and possible solutions. Thank you for your understanding.
