How to get checkbox value from FormCollection?

Question

I have a checkbox and button:

@using(Html.BeginForm())
{
    

        

        
      

Answer 1

Include completed

Will Post a value of "on" or "off".

This WONT bind to a boolean,

To receive a boolean value you can use HTML Helper Checkbox Like

@Html.CheckBox("showAll")
Include completed

Update:

If checked the html helper will post back "true,false" and if unchecked as "false"

You can have this workaround as

bool MyBoolValue= Convert.ToBoolean(collection["showAll"].Split(',')[0]);

This is because the Html helpers class adds an extra hidden field to save the state of the checkbox
