Answer 1

Just put your variable next to prefix:

<input type="checkbox" id="chk@(obj.field)" />

Answer 2

Try

<input type="checkbox" id="@("chk" + obj.field)" />

or

<input type="checkbox" id="chk@obj.field" />

Answer 3

<input type="checkbox" id="chk@(obj.field)" /> should work.

The most direct and clean way to add a prefix a suffix.

@("PREFIX " + obj.field + " SUFFIX")

Answer 4

<input type="checkbox" id="chk@(obj.field)" /> should work.

Answer 5

Best way to concate any C# variable in rozer view by using string.Format

id="@string.Format("{0}_Title", _Id)" // Apend after
id="@string.Format("Title_{0}", _Id)" // Apend before
id="@string.Format("Title_{0}_Title", _Id)" // Apend Middle
