ASP.NET Check Box Validation
I don't generally develop in ASP.NET but I am this time so be easy on me.
I am using VB and I am not developing Visual Studio.
The customer has check boxes 3 groups of them. They want at least one box checked in each group is there a way to do this?
See code for the check box grouping this might help explain.

This may not be a solution, but in the cases you described above the easiest thing you can do instead of the JS is changing the checkbox to radiobutton and assigning a groupname to them and set checked=true for one of the radiobutton.

I think I figured out what I am going to do.
When I submit the form I am going to run a variation of this.
I will test it in the morning.

Private Sub checkboxis()
Dim strchklist As String = ""
Dim li As ListItem
For Each li In solution.Items
If li.Selected Then
strchklist += li.Text + " "
End If
Next
If strchklist = "" Then
sbScript.Append("<script language=JavaScript>" + ControlChars.Lf)
sbScript.Append("<!--" + ControlChars.Lf)
sbScript.Append("alert('Please Select a Check Box'); " + ControlChars.Lf)
sbScript.Append("// -->" + ControlChars.Lf)
sbScript.Append("</script>" + ControlChars.Lf)
RegisterStartupScript(scriptKey, sbScript.ToString())
Else
sendtheemail
End If
End Sub
Although this was the right way to do it it was too much work for the money on this job. I choose a less desirable but easier way of validating the data. The post did have samples of VB the other was C#. I did ask for help with VB.
Thanks everyone.
