Pdf viewer controls do not show anymore

Posted on by wimhofland

Hello team,

in one of my canvas apps the pdf viewer stopped showing the Controls on top, without me doing anything to the App.

I can see that it renders when the pdf is showing up but then immediately disappears.

Does anyone recognize this behavior? Has something changed?

This is still not working. Are there any news why this won't be fixed or is there a new pdf viewer I don't know?

Regards, Steffen

Pdf viewer controls do not show anymore

Hello,

I had same issue recently. On every file change controls were missing.

I've created global variable and setting it false and true on file selection. That didn't worked.

Added a button that could be called, still no success.

Then I found property in PDF Viewer called "OnStateChange". So, whenever new file is selected to be displayed in viewer, I'm setting control variable to false and to true. That is working properly.

It's not perfect, but still better than nothing.

The verified answer led to an error in the Update Context

Latest response from sarfrazkahn is sort of same workaround that I use with local variable.

This would probably also work for me.

I do not hear anything from the customer anymore, so for me it is closed right now :-)

On the PDF viewer control:

Set "ShowControls" to:

showControls

Set "OnStateChange" to:

UpdateContext( { showControls: false }); UpdateContext( { showControls: true });

I have a same issue. This is used to work and now it does not.

Tried below trick of setting it to false and then true, still controls are not visible

They are visible for fraction of second during the load and then disapper :(

MS of course said cant said becasue its experimental . (for more than 2 years now )

I created a work around for this problem.

When I need the PDF viewer in the app I set "Show Control" option to false AND immediately after this to true.

Set (varControls, false);

Set(varControls, true)

I do not like these kind of solutions but it works

Unfortunately it is more complex than this. :-(

The show controls option is ON. When the page loads I can see the controls but then when the document renders, the controls disappear.

The thing that bothers me is that it worked. For a long time. and all of a sudden it stopped working.

I also know that in the description of the PDF viewer it says 'experimental', already for a couple of years.

Strange thing is that PDF viewer works even without activation of the setting in Experimental options.

thanx for the try

There's a "Show Controls" property on the PDF control. Just switch it to true to see the controls again.

You could also add a button or toggle to let the user toggle it.

I don't know why it changed on you.

Perhaps someone accidently modified it?

The PDF Viewer Control does say it's "Experimental" so it's also possible they can change things on us and maybe the controls used to be on by default.
