Make properties default not being saved

[Ondrej Svoboda]

Hi,

how does "Make properties default" works? Seems that it is valid only until program exit. When it is started again all is gone. Can't it be somehow saved in program settings?

Hi Ondrej,  

  

We are facing the reported behavior in PdfViewerControl that default annotation settings was not applied to newly opened PDF document after setting default settings in existing document. We have forwarded this to our development team for further analysis and we will update further details on March 4^th, 2020.  

 

Please let us know if our observation is different from that of your requirement.

Hi Ondrej, 

 

Thank you for your patience. 

 

As we informed earlier, marking default annotation properties was not applied to newly opened PDF document after setting default settings in existing document is a behavior. But we can make the marked default settings will be maintain after we load a new PDF document also by save and reapply them using DocumentUnloaded and DocumentLoaded event handlers. We have created a sample for your reference which can be downloaded from the below link,

We have also created a video for your reference which can be downloaded from the below link,

In the above sample, we have maintained the marked default annotation properties by storing them into the variables when the document gets unloaded and assign the settings from variables when the document gets loaded. 

 

Please let us know if the solution helps to solve your issue or kindly let us know if our observation of your requirement is different from yours.

Hi, OK this works, but it is not definitely what I expected - saving all the settings one by one. Isn't there a method which would serialize all the settings to some file and then load it back? That would be perfect.

Hi Ondrej, 

 

Based on your requirement we have modified the sample and it can be downloaded from the below link, 

https://www.syncfusion.com/downloads/support/forum/162993/ze/PdfViewerWPF-498154235  

 

In the above sample, the marked default properties of a line annotation will be fetched from the PdfViewerControl LineAnnotationSettings property and stored as a PdfViewerLineSettings type serialized object into an XML file when a PDF document gets unloaded or close the window. The stored default properties will be assigned to the PdfViewerControl LineAnnotationSettings property after it gets deserialized from the saved XML file when a new document gets loaded into PdfViewer 

 

We have also created a video for your reference, which can be downloaded from the below link,

Please let us know if the above solution helps to solve your issue or if you need any further assistance on this.

Hi,

so I need to repeat this for all 13 annotation settings (InkAnnotationSettings, HighlightAnnotationSettings, ...) to be able to save/load all the defaults? (and also update it when you add more controls in there)

Would be perfect if you'd provided a method to save and load it all in once - maybe with file path argument. Or some similar solution (auto load and save to some customizable path etc.). I think this would be useful for many other users and without it "make default" checkbox makes not much sense to me.

Hi Ondrej, 

 

On analyzed further on your requirement, we have modified the sample to save and reload the marked properties all it once. Please download the sample from the below link, 

https://www.syncfusion.com/downloads/support/forum/162993/ze/PdfViewerWPF1752601314  

 

In the above sample, we have exported the annotation settings when we unload/ exit from the application and import the annotation settings when we load the document. In the “ExportAnnotationSettings” method we have stored the list of all annotation settings as a serialized object into an XML file. In the “ImportAnnotationSettings” method the stored annotation settings are deserialized and assigned to their corresponding PdfViewerControl annotation setting.  

 

Please let us know if the above solution is helpful to achieve your requirement or if you need any further assistance on this.
