Datagrid poor performance when scrolling

[Thanh Vu]

I have a datagrid with about 20columns, and 100 rows. When binding data, the speed is good. But when i scroll, screen so laggy. Is the any tip for incr performance?

I've attach video file that record from my phone (Sony Xperia Z5). On my iPhone 6s performance is just a little better, but on iPhone 6 still unacceptable.

My sample code when using DataGrid as below:

       

           

               

               

               

               

               

               

               

               

               

               

               

               

               

               

               

               

               

               

               

               

           

       

   

Thanks.

PS: I've tried build with Release configuration, but still no chance.

Hi Thanh, 

 

Thank you for your patience. 

 

We had analyzed the issue “DataGrid lags on horizontal scrolling in Xamarin.Foms Android”. While reusing the columns the binding context will differ for each column and so it takes time to update the values for each cell which causes lag while scrolling horizontally. However, this lag can be partially optimized by the following factors. 

·        Set LoadUiView as true to the columns. 

·        Also, by setting LineBreakMode other than WordWrap the lag is optimized.
