I am using C# ASP.NET on VS2005.

I have a gridview table but it does not have a selection for Enable Editing when I right click on the Smart Tab.

Thus I manually added the edit button with the following code:

AutoGenerateEditButton="True"

The edit button has successfully appeared on my gridview like this:

When I click on the Edit button, the page is refreshed and the row is now editable:

However, when I pressed on the update button, I was brought to the error:

Updating is not supported by data source 'SqlDataSource1' unless UpdateCommand is specified.

I have no clue on how I can input or configure the UpdateCommand because I don’t see any background code for the Update button.

Need help from experienced. Thank you in advance.

Edited: Added INSERT query in SqlDataSource1, however I still met the same error when I press the Update button.

    You need to re-configure the SqlDataSource1 control though which you can add support for INSERT, DELETE, UPDATE along with SELECT.

    Take a look at this tutorial.
