[Emil]

Hi,

I am getting often below exception in my release version. I am not sure how to handles this. it looks like that it has something to do with  Syncfusion.UI.Xaml.Charts.ChartDockPanel.MeasureOverride(Size) . below is i implement sfchart and stacktrace

Hi Emil, 

 

Greetings from Syncfusion. We have tried to replicate the reported issue at our end by creating a sample with the provided code snippet, we are afraid that, we are not able to reproduce the issue at our end. Its working fine without any exception in Xamarin.Forms.UWP. 

  

Please find the tested sample below.   

Sample: http://www.syncfusion.com/downloads/support/forum/142732/ze/CH00FD~11255525233.zip 

  

Since we are not aware of your exact application scenario, we are not able to reproduce this issue at our end, so can you please revert us by modifying the sample based on your application along with replication procedure. This will be helpful for us to investigate further and provide you a better solution at the earliest. 

  

Regards, 

Bharathiraja.

Hi Emil, 

 

Greetings from Syncfusion, 

 

We have analysed your query and we would like to let you know that while using chart inside the FlexLayout directly without set size, chart is adjusting automatically while resizing the application.  

 

We have prepared a sample based by adding chart directly in FlexLayout and it can be downloaded from the below link. 

 

Sample: http://www.syncfusion.com/downloads/support/forum/142717/ze/142717-535202899.zip  

 

We can reproduce the reported issue, when adding the chart controls in the grid layout and add that grid to FlexLayout as a child without setting Width and Height to chart.  

 

Can you please confirm whether you are using the above scenario whether using chart in grid layout or directly added in FlexLayout?. If you confirm your use case scenario, we will validate the issue and provide you solution. 

 

Regards, 

Bharathiraja.
