Update command on DataAdapter

[Pothen Alain]

Hi,
last night i tried the tutorial about "The basic Databound Grid"
I have the following error message
"System.InvalidOperationException: Update requires a valid UpdateCommand when passed DataRow collection with modified rows." on the following command "this sqlDataAdapter1.Update(this.dataSet11);"
I have the same error with Access Database.
I don't think it's related to Syncfusion software, but has anyone already this problem ?
I use the 60 days trial version of VS.NET.

Alain,

Did you use the Products table as suggested in the tutorial, or did you use some other table. In order for the data wizards in Visual Studio to generate the Update command, your table must have a unique primary key.
