Hi Hüseyin,
Thanks for contacting Syncfusion support.
Based on your query we have already documented a Syncfusion knowledge base of about how to perform CRUD operations in grid with SqlDataSource.
Refer the code example.
<asp:SqlDataSource ID="SqlData" runat="server" ConnectionString="<%$ ConnectionStrings:NORTHWNDConnectionString %>"
SelectCommand="SELECT * FROM [Orders]"
...
DeleteCommand=
"DELETE FROM [Orders] WHERE [OrderID] = @OrderID"
...
|
From the above code example we can delete the record in grid based on primary key column (OrderID).
Please let us know if you need further assistance.
Regards,
Manisankar Durai.
