Hello,

Hi Sao,


Greetings from Syncfusion support.

Before proceeding further with your requirement kindly share the below details to validate further at our end.


  1. Share us entire Grid code snippet along with model class.
  2. We suspect that you are facing an issue while saving Data. Kindly ensure whether you have enabled IsPrimaryKey column on DataGrid to whose column value is unique.
  3. Share us some more details regarding your exact requirement.
  4. Share us the video demonstration of the issue with explanation.
  5. If possible share us an simple issue reproduceable sample.


The above-requested details will be very helpful for us to validate the reported query at our end and provide the solution as early as possible.


Regards,

Monisha

Hi Monisha,


I have attached a zip file containing a PowerPoint file. Please play the video attached on slides 4 and 5. Slide 4 shows the app run well within VS2022 and slide 5 shows how errors occur after the app is published to IIS.


Best regards


Sao

Hi Sao,


Thanks for the update.


We have checked your query and we could not reproduce the reported issue at our end when using CRUD operation. Kindly check the attached sample and video demo for your information.

Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/BlazorApp11437392256.zip


Kindly get back to us if your replication procedure is different from ours or share us the way you have published the IIS (whether you have used local folder to publish or any other options). If possible share us an simple sample or modify the above sample at your end. It will be very helpful for us to validate the query further at our end and help us to provide the better solution ASAP.
