Question

How can i get Boolean value or the true or false from controller to a Checkbox in View using this:

@Html.CheckBox("condition", @ViewData["Condition"])

or

<input type = "checkbox" checked = "**true or false?**">

I have this in my Controller..

public ActionResult Member(string sortOrder, string filter, string searchString, int? page, **bool? condition = false**)

and in my view is like this

please help me for this...

Answer 1

update your controller

public ActionResult Member(string sortOrder, string filter, string searchString, int? page,bool condition)
{
    ViewData["Condition"] = condition;
    // code line 1
    // code line 2
       ... 
}

If you are looking for checkbox check/uncheck code for Razor view

@Html.EditorFor(x => x.condition)

Will generate:

<input id="condition" type="checkbox" value="true" name="condition" />
<input type="hidden" value="false" name="condition" />

How does it work:

If checkbox not checked, form submit only hidden (false) If checked, then form submit two fields (false and true) and MVC set true for bool property

<input id="condition" name="condition" type="checkbox" value="@ViewData["Condition"]" />

This will always send default value, if checked
