Question

I have a search page that has 6 textboxes which i pass as FormCollection to the action in the controller. I dont want to search for records if ther is no values in textboxes.

Is there a way to loop through all textboxes in FormCollection to check which ones have values in them?

I am a student in the college and this project is part of my summer experience program.
I realize that this is a newbie question 🙂
Thank you!

Answer 1

You can loop through the FormCollection like this:

foreach( string key in forms.Keys )
{
    ...
}

However, note that the browser only sends you names and values. It does not send you the types of inputs, so you have no way to check if the value is a checkbox, unless you know all checkboxes names in advance. But if that’s the case, you don’t need to loop – just take them out of the collection by name.
