Update by either checkbox or textbox

where u write the code.
code need to be write/execute after checkbox click and textbox change value.

I'm afraid I did not fully understand the problem but... I'll try :)

To solve your task you need some event handlers for checkboxes.CheckedChanged event.

See my code below

Private Sub CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
        CheckBox1.CheckedChanged, CheckBox2.CheckedChanged, CheckBox3.CheckedChanged

        Select Case DirectCast(sender, CheckBox).Name
            Case "CheckBox1"
                setControlsValues_1()
            Case "CheckBox2"
                setControlsValues_2()
            Case "CheckBox3"
                setControlsValues_3()

        End Select
    End Sub

    Private Sub setControlsValues_1()
        If Not String.IsNullOrEmpty(TextBox1.Text) AndAlso CheckBox1.Checked Then
            Me.chckamtbot1.Text = TextBox1.Text
        Else
            '?????
        End If
    End Sub
    Private Sub setControlsValues_2()
        If Not String.IsNullOrEmpty(TextBox2.Text) AndAlso CheckBox2.Checked Then
            Me.chckamtbot2.Text = TextBox2.Text
        Else
            '?????
        End If
    End Sub
    Private Sub setControlsValues_3()
        If Not String.IsNullOrEmpty(TextBox3.Text) AndAlso CheckBox3.Checked Then
            Me.chckamtbot3.Text = TextBox3.Text
        Else
            '?????
        End If
    End Sub

anarki_jimbel,

Thankyou very much for your efforts and your response.

But what is it that you don't understand?

I will be more than glad to try to explain again.

I have 2 sections, Section1 and Section2.

On Section1, I have 5 textboxes and 5 checkboxes.

Let's call the textboxes, textbox1, textbox2, textbox3, textbox4, textbox5.

Then 5 checkboxes, checkbox1, checkbox2, checkbox3, checkbox4, checkbox5.

Then on Section2, we have another 5 textboxes - checkAmount1, checkAmount2, checkAmount3, checkAmount4, checkAmount5.

The way it is *supposed* to work is you enter a number into a textbox and then check the appropriate checkbox in Section1, then that amount goes in the corresponding textbox in Section2.

For instance, let's say we enter 2 box in textbox1 and check checkbox1 in Section1, that number - 2, will automatically be populated into CheckAmount1 in Section1.

So, whether you check a box FIRST before entering a number, or you enter a number FIRST before checking a box, as long as a number is entered into a textbox and the associated checkbox is checked as described above, that number should be automatically populated into the corresponding checkAmount in Section2.

If you enter a number but don't check a checkbox, that number should NOT be populated into the corresponding checkAmount in Section2

The way it is working so far is you MUST check a checkbox FIRST before entering a number.

If you do that, then that number goes into the corresponding CheckAmount in Section2.

We want it to work whether you check a checkbox first or you enter a number firs as long as a number is entered and the associated checkbox is checked, then that amount shouold go to the corresponding checkAmount in section2.

I hope this is clearer.

Again, thanks for your assistance.

I thought the code I posted above would do the trick but this one got me so stumped.

OK, try this code. For simplicity I have only 3 controls of each type :)

I tested and believe that is what you want

Public Class Form1

    Private Sub CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
                CheckBox1.CheckedChanged, CheckBox2.CheckedChanged, CheckBox3.CheckedChanged, _
                TextBox1.TextChanged, TextBox2.TextChanged, TextBox3.TextChanged

        Select Case DirectCast(sender, Control).Name
            Case "CheckBox1", "TextBox1"
                setControlsValues_1()
            Case "CheckBox2", "TextBox2"
                setControlsValues_2()
            Case "CheckBox3", "TextBox3"
                setControlsValues_3()
        End Select
    End Sub

    Private Sub setControlsValues_1()
        If Not String.IsNullOrEmpty(TextBox1.Text) AndAlso CheckBox1.Checked Then
            Me.CheckAmount1.Text = TextBox1.Text
        Else
            '?????
        End If
    End Sub
    Private Sub setControlsValues_2()
        If Not String.IsNullOrEmpty(TextBox2.Text) AndAlso CheckBox2.Checked Then
            Me.CheckAmount2.Text = TextBox2.Text
        Else
            '?????
        End If
    End Sub
    Private Sub setControlsValues_3()
        If Not String.IsNullOrEmpty(TextBox3.Text) AndAlso CheckBox3.Checked Then
            Me.CheckAmount3.Text = TextBox3.Text
        Else
            '?????
        End If
    End Sub
End Class

Probably Private Sub CheckedChanged not the best name. May be call it like ControlStateChanged or something else. Does not really matter :)

Please help me understand; what is the difference between your code and mine?

OK, I didn't see your whole code :)

The main trick in my code is that the event handler handles BOTH text box and check box changes:

=====================================
 Sub CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _

                CheckBox1.CheckedChanged, CheckBox2.CheckedChanged, CheckBox3.CheckedChanged, _

                TextBox1.TextChanged, TextBox2.TextChanged, TextBox3.TextChanged
=====================================

So, does not matter if you change text in a text box or check-uncheck checkbox - the system checks checkbox state and if allowed copies textbox content.

That's all!

Ask questions if not clear.
Unfortunately, it looks, we have some time shift. I live on Pacific time :)

thanks a lot.

However, I am sure there is more to this code.

I am running into many errors, like:

Handles clause requires a WithEvents variable defined in the containing type or one of its base types

or

'Name' is not a member of system.web.ui.control

It didn't solve my problem. but credit for efforts.

Thank you
