Hello everyone,

I'm getting a strange error when I try to bind a combo box to a Dataset.
Here's my code!

Private Sub Get_Data()
        Try
            Dim sqlcmd = New SqlCommand("Select * from Utility order by
Utility", sqlConn)

            daDataAdapter = New SqlDataAdapter
            daDataAdapter.SelectCommand = sqlcmd

            dsDataSet = New Dataset
            daDataAdapter.Fill(dsDataSet, "Utility")


            sqlcmd = New SqlCommand("Select * from Adjustments", sqlConn)
            daDataAdapter = New SqlDataAdapter
            daDataAdapter.SelectCommand = sqlcmd

            daDataAdapter.Fill(dsDataSet, "Adjustments")

            daRel = New DataRelation("UtilAdjust",
dsDataSet.Tables("Utility").Columns("Code"),
dsDataSet.Tables("Adjustments").Columns("Code"))
            dsDataSet.Relations.Add(daRel)

            Set_Update_Command()
            Set_Insert_Command()
            Set_Delete_Command()

        Catch ex As Exception
            MessageBox.Show(ex.Source.ToString & " - " & ex.Message,
Application.ProductName, _
            MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try

    End Sub

    Private Sub BindFields()
        Try
            Dim ctrl As Control
            For Each ctrl In Me.Controls
                If TypeOf ctrl Is TextBox Then
                    ctrl.DataBindings.Clear()
                    ctrl.Text = ""
                End If
            Next

            cbUtility.DataBindings.Clear()
            cbType.DataBindings.Clear()

            For Each ctrl In Me.GroupBox1.Controls
                If TypeOf ctrl Is TextBox Then
                    ctrl.DataBindings.Clear()
                    ctrl.Text = ""
                End If
            Next

            cbUtility.DataSource = dsDataSet.Tables("Utility")
            cbUtility.DisplayMember = "UTILITY"
            cbUtility.ValueMember = "CODE"



            tbAN.DataBindings.Add("Text", dsDataSet,
"Utility.UtilAdjust.AdjustmentName")
            lblAK.DataBindings.Clear()
            lblAK.DataBindings.Add("Text", dsDataSet,
"Utility.UtilAdjust.AdjKey")

            BindDate(tbASD, "UTILITY.UtilAdjust.AdjStartDate")
            BindDate(tbAED, "UTILITY.UtilAdjust.AdjEndDate")

            BindCurr(tbAA, "UTILITY.UtilAdjust.adjustment")

            BindType(cbType, "UTILITY.UtilAdjust.type")

            bmUtil = Me.BindingContext(dsDataSet, "Utility")
            bmAdjust = Me.BindingContext(dsDataSet, "UTILITY.UtilAdjust")

            AddHandler Me.BindingContext(dsDataSet,
"Utility").PositionChanged, _
            AddressOf dtUtil_PositionChanged

        Catch ex As Exception
            MessageBox.Show(ex.Source.ToString & " - " & ex.Message,
Application.ProductName, _
            MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try
    End Sub


First I get my data by calling Get_Data(), Next I bind my data be calling
BindFields()

I get the following error when I hit these statements. cbUtility = combo
box = System.Windows.Forms.ComboBox
cbUtility.DataSource = dsDataSet.Tables("Utility")
cbUtility.DisplayMember = "UTILITY"

Error:
"Microsoft.VisualBasic - Cast from type 'DataRowView' to type 'String' is
not valid"

Another odd thing is when the exception is raised my "Catch" doesn't pick
it
up! I get an error message on those lines and the program keeps going? Also everything works correctly, all controls are bound correctly,
including
that combo box.

THanks,
