Error: Context Menu in Datagrid

Hello, I used the exact code sample from https://blazor.syncfusion.com/documentation/datagrid/context-menu/#context-menu and an error occured, thus causing the Context Menu to not be displayed at all. 

I've copied the top level error that's being logged on the Console:

blazor.webassembly.js:1 crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Event 201 is already tracked

It used to be working on version 18.1, but it stopped working since I've migrated to 18.2.45.

Seeking your assistance on this matter, thank you!

Hello,

I noticed from the Release Notes (https://blazor.syncfusion.com/documentation/release-notes/18.2.46/?type=all#grid) that it's supposed to be patched: #285375 - ContextMenu is not rendered in Blazor Grid is fixed.

However, based on the above code sample, it's still not working on my end. I'm seeing an empty white box at the location where I right-clicked. See first row below:

Thanks for your update. 
 
We would like to inform you that, we have included the fix for “ContextMenu is not rendered in Blazor Grid (Blazor Webassembly application)” issue in our latest Blazor Weekly patch release (v18.2.0.46).  
 
We suspect that the problem might have occurred because of cache in your application. So please clear the browser and nuget cache before running the application. And also try running your application after clearing the bin and obj folders. We are attaching a working sample of the context menu Grid in WASM.  
 
We have used the codes from the above documentation to create the attached sample. Please download the sample from the link below, 
 
And if you are still facing difficulties, then the following details would be helpful for us to validate the problem and provide you a solution as early as possible. 
  1. Share the sample which you have tried from your side.
  2. Or if possible reproduce the problem with the attached sample and share with us for further analysis.
  3. Share the exact scenario or proper replication procedure.
  4. Share the complete Grid rendering codes.
 
The provided information will help us analyze the problem, and provide you a solution as early as possible.

Hi Renjith,

It turns out that this problem no longer exists on my computer. I wasn't too sure if it's because I restarted my computer which resulted in the cache being cleared. Thank you for your response too!

Before I posted this issue, I followed the steps based on https://blazor.syncfusion.com/documentation/common/how-to/upgrade-syncfusion-components-to-latest-version/#cache-problem. If I recall correctly, I also did clear my bin & obj folders. Since the problem disappeared before I could try the other solutions that you've suggested, I'm not exactly sure what is the fix to this problem.

Do you think it'll be helpful to add additional information in the above documentation based on your answer?

Thanks Renjith!
