How to reduce the dwell time when I update the System.Windows.Documents.Table ?

Question

I use the Table to show some information. But there isn't any method to set its verticalAlignment. So I add a method to set its vertical alignment which will traverse the TableCell of a Table to set its paddingwhen it is loaded. However I find it needs a long dwell time untill all of the Table be updated. What should I do to improve this ? Please give me some advice.

Answer 1

Use FixedPage instead of FlowDocument. that can improve your performance, but you need to design code to convert between FlowDocment and FixedPage. There are some samples online you could reference: https://code.msdn.microsoft.com/windowsdesktop/WPF-Printing-Overview-f28c541a

Hi Franks,

This issue seems a known performance issue under wpf because of the grouping.

So about how to reduce the dwell time.

Here is a thread talking about this issue, please take a look

As Ben said,

Fixed documents are more suitable for showing static (not reflowing) continent. In paginated views Fixed and Flow documents should work well with large amount of data. I also suggest you use Asybchronous with your method.

Have a nice day!
