Hi All,

I am trying to set the rows colours in the parent grid view base on the data. For example in the coding, if the currency is USD then set the row to chocolate colour but instead my coding shows that its all in red even though there is currency USD data in the gridview. :confused::confused:

However it does not seems to be able to be working correctly, heres my code behind,

Code:
Protected Sub gvUserInfo_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles GridView1.RowDataBound        e.Row.Cells(1).Visible = False


        Dim currency As String = e.Row.Cells(3).Text


        Dim con As New SqlConnection(ConfigurationManager.ConnectionStrings("HedgingTestConnectionString").ConnectionString)


        If (e.Row.RowType = DataControlRowType.DataRow) Then


            For Each cell As TableCell In e.Row.Cells
                If currency = "USD" Then
                    cell.ForeColor = Color.Chocolate
                Else
                    cell.BackColor = Color.Red
                    Label1.Text = e.Row.Cells(3).Text
                End If
            Next


            con.Open()
            Dim gv As GridView = DirectCast(e.Row.FindControl("gvChildGrid"), GridView)
            Dim ref As Integer = Convert.ToInt32(e.Row.Cells(1).Text)
            Dim cmd As New SqlCommand("select * from TT where Reference_NO=" & ref, con)
            Dim da As New SqlDataAdapter(cmd)
            Dim ds As New DataSet()
            da.Fill(ds)
            con.Close()


            gv.DataSource = ds
            gv.DataBind()


        End If
    End Sub
Code:
