error with access database

  • 13 years ago

    when trying to add data from my form to an access database i got this error

    An unhandled exception of type 'System.Exception' occurred in system.windows.forms.dll

    Additional information: DataBinding could not find a row in the list that is suitable for all bindings


    here is the code i have in my "add" button

    Private

    Sub btnadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnadd.Click

    validatedata()

    Me.BindingContext(Dstraining, "training").EndCurrentEdit()

    Me.BindingContext(Dstraining, "training").AddNew()

    Me.navigation_PositionChanged()

    end sub

    what did i do wrong?first  it was adding null values to the database and now i am getting an error

    i have two listbox  a combobox  and a datagrid on the form which are all binded to the access database which consists of only one table
