[Solved] Extra columns when binding JSON array on client side with dynamically created columns

[David]

I'm trying to implement client-side binding to a JSON array via the following JS:

var tableView = $find("<%= gridView.ClientID %>").get_masterTableView();
tableView.set_dataSource(GridData);

tableView.dataBind();

My columns are dynamic since they are controlled via configuration, so I have to create them on the server during Page_Load by creating GridBoundColumn instances and adding them to the grid's Columns collection (see simplified example):

GridBoundColumn column = new GridBoundColumn();

gridView.Columns.Add(column);

column.DataField = fieldBinding;

 column.UniqueName = uniquename;

column.SortExpression = fieldBinding;

column.HeaderText = fieldLabel;
gridView.Columns.Add(column);

I've found that to get any data to show up, I also have to do a preliminary data binding on Page_Load:

gridView.MasterTableView.DataSource = new string[] { };
gridView.DataBind();

Overall this works and my binding does populate, but I end up with an extra "Items" column on the right side that I cannot hide.  Getting rid of the server-side preliminary binding eliminates the extra column, but at the cost of preventing the client-side binding from occurring.  There doesn't seem to be any way to hide this extra column since it doesn't show up in the Columns collection during the lifespan of Page_Load.

Any ideas?

Ack, never mind.  I had accidentally left AutoGenerateColumns turned on.  My apologies, but hopefully this helps someone else. :-)
