With the HTML helper, how would you enforce number only without submitting? I know it was done with regular expression if you had a textbox in classic ASP.NET
<%=Html.TextBox("txtYearOfWork",String.Empty, new { maxlength = 4, size="5", autocomplete = "off" }) %>

View 1 RepliesIf i use DataAnnotations on my Model and my model have something like this:
[Code]....
and in my View, i have a textbox WITHOUT client side validation. If the user enter non-numbers caracters in this field, i would like to validate on the server side that the user have entered non-authorized caracters and message him back on that. But since that my Model's Days property is a INT, the ModelBinder can't parse the string in the int property and generate an error in the ModelState with no message at all. And if the user doesnt enter anything on this field, the ModelBinder also try to put an empty string in a int property and generate an error in the ModelState with the message "a value is required". This is not the message that is written within the DataAnnotation. I have no control on the message that is generated.
So my question is:how can i valide the users input for int properties (or DateTime, etc...) and if the user enter a bad value i can put in the ValidationSummary something like this: "You can't only enter a numeric value for Days".
I would like to know if there's a way to have a textbox that only recieves numbers only, so if any user tries to type any other character it wont take it.

View 4 RepliesI have a drop down list and a textbox on a form. If a user select employee in the dropdown box, I wish to add employee email addresses in the text box. It should do the same if users select client on the drop down (i. e. Add client addresses in the textbox). I have not been able to do it without having to click on a button.
Here is the code that should be executed:
protected void ddTemplate_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddTemplate.Text == "Employees")
txtEmailAddress.Text = "employee@abc.com";
else if (ddTemplate.Text == "Clients")
txtEmailAddress.Text = "clients@abc.com";
}
