DataKeyField in DataGrid

[shijey]

I noticed there is a DataKeyField property in DataGrid when you are building ASP .Net application. How come in Desktop Application, you cannot have DataKeyField option in DataGrid?

 

If there is no DataKeyField property, so how do you store your primary key in DataGrid? And how to retrieve the value back?

You can use the PrimaryKey of your DataTable.

 

Reason is probably that the web version cannot really bind to its source as a desktop grid.

How about DataSet1.Tables(0).PrimaryKey ? Can you use that?

 

If not, could you tell me how to do it in code-behind? And how to retrieve back the primary key value?

 

Thx
