Getting TexBox's ID's .... to Calculate

i have :

vb code:

    Private Sub Calculation()

     Dim txt1 As Decimal
            txt1 = (CS_Incoms_done.Text / CS_Incoms_target.Text) * 100
            CS_Incom_Result.Text = "%" + FormatNumber(txt, 2, TriState.False)

            Dim txt2 As Decimal
            txt2 = (CS_GovernmentService_done.Text / CS_GovernmentService_target.Text) * 100
            CS_GovernmentService_Result.Text = "%" + FormatNumber(txt2, 2, TriState.False)

            Dim txt3 As Decimal
            txt3 = (CS_RentBox_done.Text / CS_RentBox_target.Text) * 100
            CS_RentBox_Result.Text = "%" + FormatNumber(txt3, 2, TriState.False)

Dim txt4 As Decimal
            txt4 = (CS_ServiceAdvertising_done.Text / CS_ServiceAdvertising_target.Text) * 100
            CS_ServiceAdvertising_Result.Text = "%" + FormatNumber(txt4, 2, TriState.False)

  Dim txt5 As Decimal
            txt5 = (CS_ServiceCatogray_done.Text / CS_ServiceCatogray_target.Text) * 100
            CS_ServiceCatogray_Result.Text = "%" + FormatNumber(txt5, 2, TriState.False)
    End Sub

i just show you 5 textbox's of 100 textbox's .... and don't want to complete all the textbox's like this ... i want a simple code to do it..

... as you notice , every three textbox's are look a like on the first two parts of their id's..~

for example --> CS_ServiceCatogray _Result.Text, CS_ServiceCatogray _done.Text and CS_ServiceCatogray _target.Text...

~..and the last part is the same in all textbox's for geving the Result ..> _Result.Text , _done.Text and _target.Text

So... i had an idea to take the id and put the Similar two parts in an array... and use For Each something like:

Dim allItems As Array
        For Each item As Control In panel4.Controls
            Select Case item.[GetType]().Name
                Case "TextBox"

                    'here just be sure that this item is not saved in the allItems array ,if it is not  do >>'
                    allItems[Last_Item_Saved_Index+1] = DirectCast(item, TextBox).ID ',  i want  to save just the two Similar parts of the textboxs ids'


'i am not sure if this completely correct, but i wanted to do something like it['
                    Dim partOFtxt As String = allItems[Last_Item_Saved_Index]

                    Dim txt As Decimal = (partOFtxt + "_done.Text") / (partOFtxt + "_target.Text")

                    (partOFtxt + "_Result.Text") = "%" + FormatNumber(txt, 2, TriState.False)  ']'
                    'end condition'

                    Exit Select
                Case Else
        Exit Select
            End Select
        Next

i hope that you get the idea..

if you have a better idea ... it would be nice..

Thanks in advance..

I don't suppose you have the flexibility to create a user control that groups the three text boxes together and centralizes the logic that calculates the result? That way in the code behind you could loop on all of the controls in the Panel, testing for control type using "is", cast to that type and call the calculation method.

Pseudo-code:

Public Class ThreeTextboxUserControl
    Private doneTextBox
    Private targetTextBox
    Private resultTextBox

Public Sub loadValues(doneTextBoxValue, targetTextBoxValue)
Public Sub calculateResult()

In Page code behind:

Public Sub Calculation()
    For Each item As Control In panel4.Controls
        If (item is ThreeTextboxUserControl)
            [Cast item and call calculateResult()]
        End IF
    Next
End Sub

Here is the short and sweet code which gives the same result as given by your answer. Feel free if need clarification.

Private Sub Calculation()
    Dim CurParent As ContainerControl = Me
    For Each item As Control In CurParent.Controls
        Dim decZeroResult As Decimal = 0
        Select Case item.GetType().Name.ToUpper
            Case "LABEL"
                Dim ControlName As String
                Dim ResultControl As Control = item
                ControlName = ResultControl.Name
                If ControlName.ToUpper.EndsWith("_RESULT") Then
                    Dim ControlPartName As String = Mid(ControlName, 1, ControlName.Length - 7)
                    Dim TargetControl As TextBox = Nothing
                    Dim DoneControl As TextBox = Nothing
                    Dim controlsFound() As Control
                    controlsFound = CurParent.Controls.Find(ControlPartName & "_Target", True)
                    If controlsFound.Length > 0 Then
                        TargetControl = controlsFound(0)
                    End If
                    controlsFound = CurParent.Controls.Find(ControlPartName & "_Done", True)
                    If controlsFound.Length > 0 Then
                        DoneControl = controlsFound(0)
                    End If
                    If TargetControl IsNot Nothing And DoneControl IsNot Nothing Then
                        If TargetControl.Text > 0 Then
                            decZeroResult = FormatNumber(((DoneControl.Text / TargetControl.Text) * 100), 1, TriState.False)
                        Else
                            decZeroResult = 0
                        End If
                        ResultControl.Text = decZeroResult & " %"
                    End If
                End If
        End Select

    Next

End Sub

Edit: Removed part of the answer to make the rest clearer.

Or if you want to make it easy to loop through them, you could do something like this:

In your initialization code you link each textbox with the textboxes used to calculate it's value as: 

CS_Incom_Result.Tag = New KeyValuePair(Of TextBox, TextBox)(CS_Incoms_done, CS_Incoms_target)

Then you create a method as:

Public sub UpdateTextBox(t as TextBox) 
    Dim kvp as KeyValuePair(Of TextBox, TextBox) = CType(t.Tag, KeyValuePair(Of TextBox, TextBox))
    Dim txt as Decimal = (decimal.Parse(kvp.Key.Text) / decimal.Parse(kvp.Value.Text)) * 100
    t.Text = "%" & FormatNumber(txt, 2, TriState.False)
End Function

And then you could update them all in a loop as: 

For Each ctrl As Control In panel4.Controls
    If Typeof ctrl is TextBox Then
        UpdateTextBox(Ctype(ctrl, TextBox)
    Endif
Next
