Have a webcombo using a SqlDataSource (in the *.aspx - not using InitializeDataSource or binding from C#)

ComboTypeAhead="Suggest"

DataValueField="Version"

The stored procedure used by the webcombo returns Version with data type = FLOAT

When I type something in the webcombo, it does not filter based on the typed value.

Then when I click a button. I get the error (details below - please advise)

Cannot perform 'Like' operation on System.Double and System.String.
