Edit & save

[Chenyapeng]

Mode 1:

I save the data to database in ActionBegin funciton,  then I refresh the datasource, so the new data have two records in the datasource. I cant delete and edit the new data for tracker errors. 

Mode 2: I saved the data to database in the ActionCompleted Handle, the new added data has no Id. 

Only refreshed the page, not a spa.

A client ADD a record in one page. then the others who opened the same page would get the new record in the same time. so I must get the newest record in the database.

I want to know when did the grid componet  add the new data to the datasource?

Would you give some advice CRUD about the data grid?

public async void ActionBeginHandler(ActionEventArgs<Country> args)

{

// Here you can customize your code

actionInfo += "ActionBeginHandler, ";

if (args.RequestType == Syncfusion.Blazor.Grids.Action.Save)

{

if (args.Action == "edit")

{

await countryService.UpdateAsync(args.Data);

}

if (args.Action == "add")

{

// await countryService.SaveDataToDatabase();

AmISender = true;

await countryService.AddAsync(args.Data);

}

}

else if (args.RequestType == Syncfusion.Blazor.Grids.Action.Delete)

{

await countryService.RemoveAsync(args.Data);

}

else if (args.RequestType == Syncfusion.Blazor.Grids.Action.Add)

{

}

}

Hi Chenyapeng,  

 

Thanks for contacting Syncfusion support.  

 

Query: “I cant delete and edit the new data for tracker errors and I saved the data to database in the ActionCompleted Handle, the new added data has no Id” 

 

From your query we understand that you are facing issue while performing CRUD action in Grid. We have analyzed your query and we suspect that you might not have enabled IsPrimaryKey property in Grid Column. If yes, kindly ensure to define the PrimaryKey property to any of the available GridColumn whose value is unique. Based on the PrimaryKey column value only CRUD in Grid will take place.  

 

Refer our UG documentation for your reference
