Question

i have some programming aspect how can i check whether hidden field is empty or not
i mean i want to check that ListTwiHiddenField.items.cout==0 or empty how can i check this

Answer 1

HiddenFields don’t have an Items collection, they just have a Value property, which is a String. So to check if it’s empty all you need is:

if (string.IsNullOrEmpty(ListTwoHiddenField.Value)
{
}

Or you could use string.IsEmptyOrWhitespace, which would check whether the hidden field’s value is just [space] characters.
