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 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";
}
I have the following problem...
I'm developing an an asp.net 2 application in c#. This site is being built with accessibility in mind, and as such I need a to build a registration from that validates using server side scripts and
not use client side validation.I need to validate a textbox (whether any text has been entered), if a check box has been checked.
Bear in mind that I can't use any clientside code such as javascript postback that is wired into the <asp:CheckBox /> control.
how am I be able to validate multiple entries (textbox control). It seems that using custom validate is not possible because each validator has one control to validate. In my case, I have to determine if at least one entry was filled with data.

View 11 Replies I have a textbox that I am "custom" validating to lookup in a table to see if the name exists. When I test it out, if it finds a duplicate, the validation results in an error message as I would expect. First is this only works if I add autopostback to my textbox and that I click elsewhere on the page. The other issue is that after I type a string in my textbox, I want it to validate such that if it returns an error, I don't want to submit the form until the validation is good.
How would I programatically set this up?

View 6 RepliesI'm trying to create a simple user registration page. I'm using an MS Access database which has some test data in it. What I would like to do is use a CustomValidator on the user name textbox to check if the user name entered already exists in the database. I've read about the possibility of using the ServerValidate event for the CustomValidator control but I can't figure out how to make a connection to the database, query it to check the existing user names, and then fire off the CustomValidator if the user name exists.
