asp.net-mvc Model binding Validating date fields manually with dynamic formats using model binder
Example
If different users need different datetime format then you may need to parse your incoming date string to actual date according to the format. In this case this snippet may help you.
public class DateTimeBinder : DefaultModelBinder
{
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
DateTime date;
var displayFormat = Session["DateTimeFormat"];
if (value.AttemptedValue != "")
{
if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
{
return date;
}
else
{
bindingContext.ModelState.AddModelError(bindingContext.ModelName, "Invalid date format");
}
}
}
return base.BindModel(controllerContext, bindingContext);
}
