Xojo2024R4.1: WebListBox with DataSource - appears to be redrawn upon subsequent Shown event

[Grzegorz_Greg_Pasternak]

The situation: WebPage with WebListBox using DataSource class, user double clicks on entry to show “detail page”, then clicks on button which shows original page with the list - at this point the data in the list shows up, gets cleared and then shows the data again.

Pressed event behind this button has this code:

mReferrer.Show
mReferrer = nil
Self.close

I have checked to make sure that the Shown event does not rebuild the list. So my question is, why does the list appears to be cleared and redrawn upon simply bringing it back via Show method.

Is this normal?

So my question is, why does the list appears to be cleared and redrawn upon simply bringing it back via Show method.

My guess is that something like a Refresh is triggering a redraw/datasource check.
Maybe normal as how it was designed.
If you create a sample, you can open a Feature Request for a better way for the user to control that Refresh (not trigger the datasource check/redraw). As said, this is only a guess. Maybe Greg or Ricardo can confirm or add more information.
