[Problem/Bug]: Detect if a Find session is in progress or has been stopped

[pushkin-]

What happened?

I detect Ctrl+F/F3 in my app.

When Ctrl+F is pressed, I use the StartAsync API to show the Find popup.

If F3 is pressed, I'll show the Find popup in the same way if one isn't already, but if it's started already, I want to continue searching the same Find session.

I need to know if a Find is in progress or not. Closing the Find popup and then querying the FindInterface still shows an active session (I suppose, because Stop wasn't explicitly called):

(it still shows this after the Find popup is closed; it's possible this is expected actually since the Find text is preservered in a browser too when closing and reopening it; though in WebView2 it's only preserved once and then the text I was searching for gets reset)

I want to know when the FInd popup was closed, so I can know if F3 should open a new Find popup via StartAsync or continue a search via FindNext/FindPrevious. Also, if the Find UI has been closed, I can call Stop() to clear out the text in the Find UI, since in my case, I want to reset everything on close.

So perhaps an event that's triggered when the popup closes would be useful here; alternatively, it might be nice to call one API and have it figure out if it should open a new Find popup or focus and search an existing one.
StartAsync will do a search if a find session is in progress, but it will search in the same direction as was searched last time (according to the docs). If a user presses Shift+F3 or F3, I want to adjust the search direction in response to that which would require explicitly calling FindNext or FindPrevious (which doesn't seem to work as per #5060)

Importance

Important. My app's user experience is significantly compromised.

Can you please show this in a sample app which I can run on my machine.

@chetanpandey1266 this issue somewhat intersects with others issues I've opened up. Like testing this runs into other problems I've reported related to Focus and FindNext not working.

Sure I can post an example. I'll add the zip below, but basically my changes to the basic WebView2 WinForms example are: I disable AreBrowserAcceleratorKeysEnabled in WebView2Control_CoreWebView2InitializationCompleted and then add this code:

	private void WebView2Control_KeyDown(object sender, KeyEventArgs e)
	{
		if (e.KeyCode == Keys.F && Control.ModifierKeys.HasFlag(Keys.Control))
		{
			DoFind(null);
		}
		else if (e.KeyCode == Keys.F3)
		{
			DoFind(Control.ModifierKeys.HasFlag(Keys.Shift));
		}
	}

	private void DoFind(bool? searchForward)
	{
		var coreWV2 = webView2Control.CoreWebView2;
		if (searchForward == null)
		{ // we're doing a new search
			var findOptions = coreWV2.Environment.CreateFindOptions();
			findOptions.FindTerm = string.Empty;
			coreWV2.Find.StartAsync(findOptions);
		}
		else
		{
			if (searchForward == true)
			{
				// however, if the Find popup was closed, I'd want to open it back up
				// and FindNext doesn't seem to do that.
				coreWV2.Find.FindNext();
			}
			else
			{
				coreWV2.Find.FindPrevious();
			}
		}
	}

Hi @pushkin-
I already added comment regarding to this issue in one of your bug.

Here just commenting on the comment that you have added above FindNext call. FindNext/FindPrevious expects a find session to be active to work as specified in the official documentation. Please consider adding StartAsync to start a new session.

@chetanpandey1266 I'm not understanding how your comment relates to my issue. I already have a StartAsync call.
I want to intercept F3 and start a new session if one isn't already started, and otherwise use FindNext() to search the next term.
But it's not clear to me how I can know if a Find session is in progress (by which I specifically mean, the Find popup is still showing).

I want to know if the Find popup is being displayed or not, so I can know whether to make another StartAsync call or a FindNext call.

[chetanpandey1266]

@pushkin- I think ActiveMatchIndex is a good indication whether a Find session is active or not. The Find session might be active even if you have closed the Find popup using the cross button.

Also if the find session is active ( but the Find popup is closed ) and you do FindNext the Find popup will again appear.

The decision of calling StartAsync or FindNext can be made based on the ActiveMatchIndex.

I hope this was helpful.

The Find session might be active even if you have closed the Find popup using the cross button.

This is one of the problems. If the user closes the Find popup, I want to properly stop the Find session such that the next time they hit Ctrl+F, it's blank. And there isn't a way for me to hook into their closing the Find popup and stopping the session programmatically.

And Calling Stop() doesn't reset ActiveMatchIndex and MatchCount.

So it seems like I have no way of knowing it the Find popup is currently showing or not, and so when I intercept F3, for instance, I don't know if I'm supposed to call StartAsync for a new Find popup or FindNext. (And regardless, calling FindNext doesn't work for me, but that's due to another issue I reported) @chetanpandey1266
