What is the best way to create complex pdf in Xamarin.Forms

I want to create a pdf from my UI fields which contains some texts, some grids and also pictures (something like the image that I've attached), is it possible to do so? and could you please tell me what's the best way to do so? should I create my own template or is there any other way? could you please help me?

Thanks in advance,

Reihaneh

Thank you so much for providing the sample, just one more question, I am trying to give backgroundBrush to one of the cells in my pdfGrid using this line of code: 

but applying this style makes the whole row gray, I want only cell[0] in row[0] gets the style, am I doing something wrong?

Thanks in advance

Hi Reihaneh, 

Thank you for your update. 

The BackgroundBrush is property to apply the background color of a cell. We have ensured code snippet shared from your side. The first row first cell (i.e. Rows[0].Cells[0]) background color only changed as light gray. Please find the sample and output PDF below for your reference. 

Sample: http://www.syncfusion.com/downloads/support/forum/141022/ze/GettingStarted1843786532 

Output PDF: http://www.syncfusion.com/downloads/support/forum/141022/pd/Output-1213892692 

We suspect that the background brush style may applied in other PdfGridCells in a row. Please check the above sample and let us know, if you need further assistance in this.

Thank you for your reply, problem solved after removing the following line:

but it's kinda weird, because in testObjectStyle, I had just defined a Font property like this

no backgroundBrush, so why does it effect BackgroundBrush property as well?

In the sample you have provided for inserting an image to a pdf, you've used this code snippet:

so the Xamarin_JPEG.jpg is in PCL with build action set to embedded resources, Is there any way to use an image that is in drawable folder? and not pcl?

Hi Reihaneh, 

 

The image from the device can be loaded as Stream to PdfImage constructor. Please refer the below mentioned Microsoft UG documentation for Xamarin to read or write files to internal storage. 

Link: https://docs.microsoft.com/en-us/xamarin/android/platform/files/#reading-or-writing-to-files-on-internal-storage 

 

Let us know if you need any further information.

Thank you this worked but in my app I have more than 50 images, so I should write this line for all the images?

 var icon = BitmapFactory.DecodeResource(activity.Resources, Resource.Drawable.logo);
