What controls??

[vivsm]

Hi there,

i m a beginner in VB.Net.

i have 2 forms, F1 contains a ?Control and button1 & buton2. when the user click on the button1, the F2 with a datagrid display.The user can select a particular product by double click on the datagrid. The ProdName and Price will fill in the ?Control in F1. Of course this ?Control can display a list of prodName and price if the user click on the button1 and select more products. If the user click on Button2 it will show the total cost of the products.

What ?Control should i used ??
What is the coding to write on that ?Control??

Any help is appreciated.
Thanks,

viv

Hi,

Presumably you fill the datagrid from more than one table (if you stick to Data Base Normal Form Rules).

If so, there are slightly involved ways of using a ListBox or a ListView, but why don't you just use two textboxes ( or probably Labels are more appropriate)?

say we have form1 and form2. on form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
      Dim f As New Form2()
      f.ShowDialog()
      Dim s As Form2.authors = f.selecteditems
      If Not IsNothing(s) Then
         TextBox1.Text = s.id
         TextBox2.Text = s.lname
         TextBox3.Text = s.fname
         TextBox4.Text = s.phone
         TextBox5.Text = s.address
         TextBox6.Text = s.city
         TextBox7.Text = s.state
         TextBox8.Text = s.zip
         TextBox9.Text = s.contract
      End If
   End Sub

and on form2

Dim cn As New SqlConnection()
   Dim da As New SqlDataAdapter()
   Dim dt As New DataTable()
   Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
      cn.ConnectionString = "user id=sa;password=password;initial catalog=pubs;"
      cn.Open()
      da.SelectCommand = New SqlCommand("select * from authors", cn)
      da.Fill(dt)
 
      DataGrid1.DataSource = dt
   End Sub
 
   Public Structure authors
      Dim id, lname, fname, phone, address, city, state, zip, contract As String
   End Structure
 
   Dim s As authors
   Public ReadOnly Property selecteditems() As authors
      Get
         Return s
      End Get
   End Property
 
   Private Sub DataGrid1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.DoubleClick
      s.id = dt.Rows(DataGrid1.CurrentCell.RowNumber)(0)
      s.lname = dt.Rows(DataGrid1.CurrentCell.RowNumber)(1)
      s.fname = dt.Rows(DataGrid1.CurrentCell.RowNumber)(2)
      s.phone = dt.Rows(DataGrid1.CurrentCell.RowNumber)(3)
      s.address = dt.Rows(DataGrid1.CurrentCell.RowNumber)(4)
      s.city = dt.Rows(DataGrid1.CurrentCell.RowNumber)(5)
      s.state = dt.Rows(DataGrid1.CurrentCell.RowNumber)(6)
      s.zip = dt.Rows(DataGrid1.CurrentCell.RowNumber)(7)
      s.contract = dt.Rows(DataGrid1.CurrentCell.RowNumber)(8)
      Close()
   End Sub

Hi,
i am having another problem.
when I used a comboBox to search for a customer. The customer data will display in a grid. BUT i always get the wrong data from what i selected from the grid. How can i solved this problem?

On form2

Private Sub btnSearchName_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchName.Click

With Me.dvCustomer.Table

With DataGrid1
.CaptionText = "Search by Last Name"
End With

If cboLastName.Text = "<ALL>" Then
.DefaultView.RowFilter = "CustLName like '%'"
Else
.DefaultView.RowFilter = "CustLName like '" & cboLastName.Text & "%'"
End If

If BindingContext(Me.DataSet11.Customers).Position < 0 Then
With DataGrid1
.CaptionText = "Database is empty !"
End With
End If

dt = .DefaultView.Table

End With

Me.DataGrid1.DataSource = dt

End Sub

Private Sub DataGrid1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.DoubleClick

s.id = dt.Rows(DataGrid1.CurrentCell.RowNumber)(0)
s.Lname = dt.Rows(DataGrid1.CurrentCell.RowNumber)(1)
s.Fname = dt.Rows(DataGrid1.CurrentCell.RowNumber)(2)
s.title = dt.Rows(DataGrid1.CurrentCell.RowNumber)(3)
s.ic = dt.Rows(DataGrid1.CurrentCell.RowNumber)(4)
s.DoB = dt.Rows(DataGrid1.CurrentCell.RowNumber)(5)
s.deposit = dt.Rows(DataGrid1.CurrentCell.RowNumber)(6)
s.g = dt.Rows(DataGrid1.CurrentCell.RowNumber)(7)
s.jd = dt.Rows(DataGrid1.CurrentCell.RowNumber)(8)
s.add_1 = dt.Rows(DataGrid1.CurrentCell.RowNumber)(9)
s.add_2 = dt.Rows(DataGrid1.CurrentCell.RowNumber)(10)
s.postcode = dt.Rows(DataGrid1.CurrentCell.RowNumber)(11)
s.city = dt.Rows(DataGrid1.CurrentCell.RowNumber)(12)
s.state = dt.Rows(DataGrid1.CurrentCell.RowNumber)(13)
s.hp = dt.Rows(DataGrid1.CurrentCell.RowNumber)(14)
s.wp = dt.Rows(DataGrid1.CurrentCell.RowNumber)(15)
s.cp = dt.Rows(DataGrid1.CurrentCell.RowNumber)(16)
s.email = dt.Rows(DataGrid1.CurrentCell.RowNumber)(17)

Close()

End Sub

On form1
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click

Dim f As New frmCustSearch
f.ShowDialog()
Dim s As frmCustSearch.Customers = f.selecteditems
If Not IsNothing(s) Then
txtCustomerNo.Text = s.id
txtFirstName.Text = s.Fname
txtLastName.Text = s.Lname
cboTitle.Text = s.title
txtICNo.Text = s.ic
txtDoB.Text = s.DoB
txtDeposit.Text = s.deposit
If s.g = "M" Then
rbM.Checked = True
ElseIf s.g = "F" Then
rbF.Checked = True
End If
txtJoinDate.Text = s.jd
txtAddress_1.Text = s.add_1
txtAddress_2.Text = s.add_2
txtPostcode.Text = s.postcode
txtCity.Text = s.city
txtState.Text = s.state
txtHPhone.Text = s.hp
txtWPhone.Text = s.wp
txtCPhone.Text = s.cp
txtEmail.Text = s.email

End If
