Automatically generate Guid for ID column that is set as IsPrimaryKey="true" when adding new row to grid

[David Adler]

I am using SyncFusion.Blazor v18.1.0.58

I have a Grid where the grid items have a GUID for the primary key. When I click on the Add command button, I want to automatically populate the Id column with a new Guid value so that if I later click on Delete to remove a given row, the Guid can be used to allow the delete to work on the selected row. Right now, with the Id field null, when I click on the Delete button, all rows are deleted form the grid. 

Should I use an event that fires when I click on the Add button or is there a built in way to generate the key for a new record?

If I need to use an event, which event would work the best for this need?

OK, I figured out one solution. 

On my Grid, I added a GridEvents section;

<GridEvents OnActionBegin="BeginHandler" TValue="TierPrice"></GridEvents>

Then in my code, I added the following;

        protected void BeginHandler(ActionEventArgs<TierPrice> args)

        {

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

            {

                if (args.Data.Id == Guid.Empty)

                {

                    args.Data.Id = Guid.NewGuid();

                }

            }

        }

This seems to work the way I want.

Hi David,

   I stumbled across this post looking for a solution to the same problem, and I used your solution until I realized that it works just as well to initialize the Id field to a new Guid in the first place:

public class TierPrice 

{

   public Guid Id { get; set; } = Guid.NewGuid();

}

   This way, every newly created TierPrice object will have a unique Id to begin with.

John
