Question

i want to add combobox items and use any other controls in module but when i try to use my combobox there, is not recognized. In Window Form Application there was no problem, but in a WPF application I do not know now how to do it?

In WinForm App i do in Module.vb something like that

 Sub FillComboBox()

        Dim SQLStr As String = "use testowa Select COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE (TABLE_NAME = 'Import')"
        Dim Reader As SqlDataReader
        Dim cmd As New SqlCommand(SQLStr, myConnection)

        Form2.ComboBox7.Items.Add("None")
        Form2.ComboBox3.Items.Add("None")


        Reader = cmd.ExecuteReader()

        While Reader.Read()
            Form2.ComboBox1.Items.Add(Reader.Item("COLUMN_NAME"))
            Form2.ComboBox2.Items.Add(Reader.Item("COLUMN_NAME"))
            Form2.ComboBox4.Items.Add(Reader.Item("COLUMN_NAME"))
            Form2.ComboBox5.Items.Add(Reader.Item("COLUMN_NAME"))
            Form2.ComboBox6.Items.Add(Reader.Item("COLUMN_NAME"))
            Form2.ComboBox7.Items.Add(Reader.Item("COLUMN_NAME"))
            Form2.ComboBox3.Items.Add(Reader.Item("COLUMN_NAME"))
        End While

        Reader.Close()


    End Sub

Now i need to do the same thing in WPF app.

Please help, these are my first steps in WPF 🙂

Answer 1

• fill a collection (eg. List of string) from your SQL
• set this collection as the ItemsSource for your combobox

thats all

ps: pls read something about binding in wpf. dont try to code your winform style with wpf.
