Hi there,

I am having a problem with populating a dropdownlist. The code is as follows :


            myConnection = New SqlConnection ("server=slserver;uid=;pwd=;database=meta_dev")
            SQL$ = ""
            SQL$ = SQL$ & " select      glpd_key      "
            SQL$ = SQL$ & " from        gl_period   "
            myConnection.Open()
            myCommand = New SqlCommand(SQL$, myConnection)
            myDataReader = myCommand.ExecuteReader()
            Me.ddl_glperiod.DataSource = myDataReader
            Me.ddl_glperiod.DataBind()
            'close connection to item_map_gl
            myConnection.Close()

        ddl_glperiod.SelectedIndex = 15
           
When the page load - it populates the dropdownlist with System.Data.Com.... If i debug the code, there is no errors.

Can someone help please ....

Thanks

Hi venterm,

You need to specify the DataTextField and DataValueField properties so that the dropdown knows what data to display:

            myConnection = New SqlConnection ("server=slserver;uid=;pwd=;database=meta_dev")
            SQL$ = ""
            SQL$ = SQL$ & " select      glpd_key     "
            SQL$ = SQL$ & " from        gl_period   "
            myConnection.Open()
            myCommand = New SqlCommand(SQL$, myConnection)
            myDataReader = myCommand.ExecuteReader()
            Me.ddl_glperiod.DataSource = myDataReader
            ddl_glPeriod.DataTextField = "glpd_key"
            ddl_glPeriod.DataValueField = "glpd_key"
            Me.ddl_glperiod.DataBind()
            'close connection to item_map_gl
            myConnection.Close()

        ddl_glperiod.SelectedIndex = 15
