RichTextBoxAdv.IsVirtualizing = true

Question

Hi there, with

RichTextBoxAdv.IsVirtualizing = true;

it seems it still loads all the pages of an e.g. 50 pages document.

Update: I understand (now) that it loads but does not render all pages. Still it takes a long time.

Please comment.

Thanks!

Oh in all my RichTextBoxAdv posts, I am referring to 19.3.0.57.

And it's a great tool, despite all my problems.

Hi Gorog,Thanks for the patience.When IsVirtualizing   is made true, The SfRichTextBoxAdv control calculates the number of visible items and creates UI elements only for visible items. when the document loaded, first it would be converted into our DOM and layout the entire document, UI elements are created only when they are visible to utilize minimal memory.Generating many UI elements when only a few elements might be on the screen can adversely affect the performance of your application. By default, IsVirtualizing is true and need not to force set true.please below link to know more about virtualizationhttps://help.syncfusion.com/wpf/richtextbox/virtualization Please let us know if you have any other questions.Regards,Kalaivannan Ganesan
