Why does Checkbox Always Evaluate as False?

Have a WinForm with checkbox control and the following property settings:

          Name: Chkbx
     AutoCheck: True
       Checked: False
    CheckState: Unchecked

Button on same WinForm with these settings:

    Name: btnOK
    Text: OK

    Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
        If Me.Chkbx.Checked Then
            MsgBox("True")
        Else
            MsgBox("False")
        End If
    End Sub

Regardless if the checkbox is checked or unchecked, the button click always returns msg of False. What am I doing wrong?

Works perfect for me...  Any chance you could have the wrong checkbox?

If Chkbx.Checked = True Then

bla bla

Test this
Set a watch for chkbx.checked ... that should tell you when the property value changes since you start out by having it unchecked.

Are you by any chance setting Chkbx.Checked= false in the Page_Load or somewhere?
Do you mind sharing all code wherever Chkbx is referenced...
i think in page_load u r unchecking the checkbox..
To uncheck the checkbox in page_load


If Not Page.IsPostBack Then
          Chkbx.Checked = False
End If

Open in new window

Guys
Brian is using a windows application.Where does the page load come from here.

The only code I have in my WinForm is this.

Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
        If Me.Chkbx.Checked Then
            MsgBox("True")
        Else
            MsgBox("False")
        End If
    End Sub

Testing for
        If Me.Chkbx.Checked = True Then
yiields the same result; The code always throws the False msgbox, even when the checkbox is checked. If I set a breakpoint on the IF statement and step thru ithe code, it always processes the Else condition, regardless if the checkbox is checked or unchecked.

I running VS2005. Is there a way that I can verify that I have the latest install and current service packs, etc?
This is not something that would be fixed in a service pack or a later .net framework version. It is definitely not a VS bug either. I suggest that you add a watch not a breakpoint for Chkbx.Checked. Put a breakpoint in form_load (if you dont have form_load add it with a simple dim i as integer statement and put a breakpoint there). Also add another checkbox and see if you are just having this issue with a particular checkbox or all of them.

As a test, I created a brand new project, and I don't have the problem within the new project.

Can VS projects become corrupt? Is there a way to "clean up" or "repair" a project? Can I simply add all the objects from my original  project to the new project in order to avoid any possible corruption (if that is, in fact, the problem)?

Thanks.
