Hey

Creating checkboxes at runtime is not a big deal, but please specify where and in which situation you need these checkboxes, a bit clarity on this issue is needed

As mike said, this is a trivial matter but we do need more of an explination as to how you want to implement this.

I will only tell you how to do it, not do it for you.
Unless, of course, you want to hire me to do work for you.

Hi

As said in the earlier posts by me and parsons, this can be achieved easily, just look at the code below where I have created checkboxes at runtime and added them to a Panel control.

            'Declare checkbox
            Dim chk As HtmlInputCheckBox

            'Loop
            Dim i As Integer
            For i = 0 To 3 Step i + 1
                'Instantiate and create checkbox
                chk = New HtmlInputCheckBox()
                chk.ID = "chk" + i

                'Create a panel and add the checkboxes to it
                pnlCheck.Controls.Add(chk)

            Next

Regards
Mike

Replace the error line with the line below, + is the operator to concat in C#, while in VB its &

chk.ID = "chk" & i

Hi

Just loop through the controls of panel, cast it to a checkbox and find whether it is checked, if so pass the value to the next page as querystring.

As a general rule, please understand we are here to help you out, not do the work for you. If you face any difficulties, let us know and we shall help you out.

Hello.

I am very new at the VB.Net language. I have impressed myself with finding this discussion as I had the same question. I am using VB2003 and I was wondering if someone could let me know how to determine the number of checkboxes created on the form. This would be after the subroutine has already created the checkboxes and ended. I would prefer not to pass the number of checkboxes throughout the program.

Happy Thanksgiving to the people that celebrate the holiday, and Happy Thursday to those that do not.

Thanks for helping!
