Describe the feature/enhancement you need
Hi Support Team,
We are currently developing a Windows Forms desktop application that utilizes the Microsoft WebView2 control to display internal PDF documents.
We need to implement a security requirement (or custom workflow) that intercepts the "Save As" button click on the built-in Chromium PDF viewer toolbar to trigger our own custom application dialog/logic instead of the standard Windows save dialog.
Because the built-in PDF viewer operates within an isolated chrome-extension:// origin, standard JavaScript DOM manipulation and event listeners are blocked by cross-origin security sandboxing. We are seeking your guidance on the recommended architectural approach for this.
Thank you in advance
Adrian
The scenario/use case where you would use this feature
When rendering a page what displays a PDF, I would like to overwrite the default functionality of the save button with my own functionality.
How important is this request to you?
Impactful. My app's user experience would be significantly compromised without it.
Suggested implementation
