Textbox For Integer Input With Multiple Validators?
Sep 15, 2010
I have a textbox that I want the user to enter an integer in.1) I have created a required field validator, to ensure it is not left blank.2) A compare validator, to ensure the value entered is an integer using datatypecheck.3) A range validator to limit the range of the entered integer.If a letter is entered, instead of an integer, errors from both 2) and 3) are displayed.Is there a way to only show the error from 2) if a letter is entered and 3) if the integer is out of range - rather than both?

I have a page where I am using 2 update panels. The first update panel contains a form that has some validation tied to it. The second on has a simple form, but no validation. When I go to use the form in the second panel, the postback is halted by the validators in the first panel. Everything works as it should when I remove the validators.

Since I'm new to coding and I'm trying to understand why here is a little more detail on the question.If you have a text box and you are limiting the input to say 2 charactrs do you really need to validate the input further? What I have is a text box that has a max length of 2. Is there a security reason to add a validator to the textbox. I should add this is in Asp.net.

can we use the same validator of a control for two different buttons, or do we need to write add a validator for each control for two different buttons.

Is it possible to access a control's attributes within a custom validation method? Lets say I'm validating a textbox called txtName. Is it possible to access the ID of it or anything? args seems to only give me access to the value.

I'm working on a multipage form in .Net using AJAX (UpdatePanels). I am stuck right now trying to get a class added to the textbox that is invalid to basically highlight it red.
I found a sample online using this code:
$("span.invalid").bind("DOMAttrModified propertychange", function (e) {
// Exit early if IE because it throws this event lots more
if (e.originalEvent.propertyName && e.originalEvent.propertyName != "isvalid") return;
var controlToValidate = $("#" + this.controltovalidate);
var validators = controlToValidate.attr("Validators");
if (validators == null) return;
var isValid = true;
$(validators).each(function () {
if (this.isvalid !== true) {
isValid = false;
}
});
if (isValid) {
controlToValidate.removeClass("invalid");
} else {
controlToValidate.addClass("invalid");
}
});
That works perfectly, in IE only. For some reason this code does not ever fire in Firefox. I've looked up the DOMAttrModified event and it sounds like this should work in Firefox, hence it being in the code. I must be missing something though because it does not work.
I'm open to other solutions for what I am trying to accomplish here if anyone has something good. Basically the form is 3 pages right now. Page 1 has a variable number of fields that require validation. It could be 5, or 13 fields, based on a checkbox. Page 2 has another set of fields that need to be validated separately. Obviously when I am on page 1 it should not try to validate page 2, and vice versa.

I'm trying to update a db record via a business object, based on a users input.
In my button event handler, I check for a null or empty value like this before I set the object properties:
[Code]....
But if the textbox is empty, I get the "System.FormatException:
Input string was not in a correct format." in the line:
[Code]....
How can this be?

If I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator?
Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?

here is the problem I have:There are 2 textboxes: uxActiveDate, uxExpireDate. Expiredate has 2 validators attached to it:
In the markup:
[Code]....
In the code behind file:
[Code]....
The problem is when expire date is selected before active date, and current date, then both the error messages are displayed. I have to set priority or something so that these 2 messages are not displayed at the same time. Is it doable?
PS: Since if required field validator does not pass, then other validators dont execute, I guess there is a way to set priority so that if one validation is not passed others will not execute. Validation summery is not an option, since it does not show message client side.

I currently have a TextBox using: <%: Html.TextBox("TextBox1") %> How do I get the value of what is typed into the TextBox as a string so that I can use that string variable throughout my application? The view has he following with the inherits on top of page to model. This page is named "InputNumbersSection":
<%: Html.TextBoxFor(m => m.Number) %>
and the action:
<%: Html.ActionLink("Get Number!", "DisplayNumbersSection") %>
The Model has this:
public class NumberModels
{
public string Number { get; set; }
}
The controller has the following:
public ActionResult DisplayNumbersSection(NumberModels model)
{
if (ModelState.IsValid)
{
string TextBoxValue = model.Number;
ViewData["Number"] = TextBoxValue;
}
return View();
}
The ViewData I use in another page to return the number from the textbox typed in the view. When I type somthing into the textbox, I do not see the property getting hit or executed. The "Number" property returns NULL all the time. It almost seems as if it is not picking up what I type into the TextBox

I'm trying to devise a form that will allow me to input multiple contacts. It's a pretty long form so far and I want to keep it as short as possible. I was thinking of just having one set of fields for contact inputting which will add this contact to a list box or gridview but I'm not sure that is the most elegant solution. Could anyone else point me in the right direction to something good I can use?
I'm writing in HTML / asp.net / javascript.
