ASP.NET MVC Conditional validation
- by Peter Stegnar
How to use data annotations to do a conditional validation on model?
For example, lets say we have the following model (Person and Senior):
public class Person
{
[Required(ErrorMessage = "*")]
public string Name
{
get;
set;
}
public bool IsSenior
{
get;
set;
}
public Senior Senior
{
get;
set;
}
}
public class Senior
{
[Required(ErrorMessage = "*")]//this should be conditional validation, based on the "IsSenior" value
public string Description
{
get;
set;
}
}
And the following view:
<%= Html.EditorFor(m => m.Name)%>
<%= Html.ValidationMessageFor(m => m.Name)%>
<%= Html.CheckBoxFor(m => m.IsSenior)%>
<%= Html.ValidationMessageFor(m => m.IsSenior)%>
<%= Html.CheckBoxFor(m => m.Senior.Description)%>
<%= Html.ValidationMessageFor(m => m.Senior.Description)%>
I would like to be the "Senior.Description" property conditional required field based on the selection of the "IsSenior" propery (true - required). How to implement conditional validation in ASP.NET MVC 2 with data annotations?
UPDATE
Found nice solution. Look below.
