validate CheckboxList

[Mike]

I have a checkboxList on my page and its required that at least item is
checked. Is there a way to validate that at least one is checked when the
user clicks the 'submit' button?

Hi Mike

user clicks the 'submit' button?

there is no out-of-the-box solution build in ASP.NET to do that.
but you can implement your own validator control, implementing from the
BaseValidator class,
or try whether a existing solution do the work for you (first two results):

Peter,
I added a method to go through the checkbox list and if none was
selected return false, else true, then I added my data if it was true
something like this;

public bool isChecked()
{
bool chkBox= false;
for (int i = 0; i <= (chkList.Items.Count - 1); i++)
{
if ((chkList.Items.Selected))
{
chkBox = true;
}
}
return chkBox;
}
