I wanted to write a regular expression using the ASP.Net RegExp validator that would ensure a field contains only numeric and decimal values, and at least one character.
^[0-9]{1,40}(.[0-9]{1,2})?$
Essentially: [0-9]{1,40} - meaning at least one to 40 numeric characters.The ASP.Net regexp validator does not fire for an empty field - where there is not at least one character.

regularexpression validator for dd/MM/yyyy format
View 5 RepliesI have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here?
<asp:TextBox ID="txtActualCost" runat="server" Width="120px" CausesValidation="true"></asp:TextBox>
<asp:RegularExpressionValidator ID="regExValActualCost"
ControlToValidate="txtActualCost"

In my website I need to validate email address format. I need to use ASP.Net RegularExpression Validator
View 1 Replies<asp:RangeValidator ID="RangeValidator1" runat="server" Display="static" ControlToValidate="txtcpwd"
ErrorMessage="Password must be minimum 6 & max 8 characters" Type="String" MinimumValue="6"
MaximumValue="8" Visible="false">
Even if I have minimum 6 characters its still displaying the message.
I want to disable a ASP.NET RequiredFieldValidator with JavaScript. Actually I'm using the following code:
function doSomething()
{
var myVal = document.getElementById('myValidatorClientID');
ValidatorEnable(myVal, false);
}
This disables the validator. But my problem is, that I'm using a ValidationSummary. And this summary shows the validation message, even if I disable the validator.
how to disable the validator in the ValidationSummary too?

I have the need to remove my custom field validators on the clientside based on certain conditions
View 1 RepliesCan I trigger a javascript function from a validator?Or, can I trigger a javascript function when validators are validated? Before, while, or after?
View 1 RepliesI know the built-in ASP.Net validators come with a client-side framework, however I've been unable to find anything that lets me check a single validator for it's Valid state.
The validator in question is a RegularExpressionValidator, which I use to determine whether an e-mail address is valid or not.
Here's some brief code:
[code]....
I have 3 textbox with 3 asp.net validators targeting each textBox in a Web Form.
textBox1RequiredValidator1
textBox2
RequiredValidator2
textBox3
RegularExpressionValidator1
Can i fire RequiredValidator1 only When i Move the focus out of TextBox1 ?The Same thing has to happen for all the other TextBoxes and fire their corresponding validators.
I've set up a page that uses JavaScript to hide or show rows in an HTML table, depending on the state of a checkbox.
So far, so good. But this is a data entry form and some rows include validation controls. However, it appears that if I hide a row (using JavaScript: style.display = 'none') that contains a validation control, the control still validates on an attempt to postback.
way I can do this but have the validation controls not do anything if that row is hidden?

I'm try to do validation on a textbox input to validate a phone number.I have an asp.net textbox and checkbox. The default is to validate a US phone number and when I check the checkbox I should change the RegularExpression and error message to validate an international phone using my own RegularExpression.

I've got two questions - first of all, why does .net render a javascript onclick event for asp buttons when there's a custom validator on the same page, and secondly, how can I get rid of the javascript?
It works fine when javascript is turned off, so I don't know what the point of it is. Here's a mini example:
<form id="form1" runat="server">
<asp:Button ID="Button1" OnClick="Button1_Click" Text="test" runat="server" />
<asp:CustomValidator ID="CustomValidator1" runat="server"
OnServerValidate="Stuff_Validate" EnableClientScript="false">
</asp:CustomValidator>
</form>
This will generate the following html for the button:
<input type="submit" name="Button1" value="test" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("Button1", "", true, "", "", false, false))" id="Button1" />
Without the custom validator, it's:
<input type="submit" name="Button1" value="test" id="Button1" />
I am trying to use the ASP.NET regularexpressionvalidator to apply a password policy that enforces the following policy:
Password should include at least 6 characters, at least one small letter, at least one Capital letter, at least one number, and at least one special character. Here is the expression:
^.(?=.{6,})(?=.d)(?=.[a-z])(?=.[A-Z])(?=.[@#$%^&+=!-_()?]).*$
The strange thing I found is that it works fine except with the following scenario, If I use all the required combination without special character such as Hello123" it finds it as valid password. below is the controls used for testing.
iam using regular expression in javascript function to validate email. iam calling javascriptfunction using asp.net custom validator. email validation is working. when i click the textbox the cursor is in the middle of the textbox. it's not moving to endof the text or beginning of the textbox, if the textbox is empty. do you have any idea about this error.

I'm using this code to access controls inside a gridview using javascript:
[code]....
Thing is that for some reason it doesn't locate Validators. If i add the line - alert(sid) , it will show me all the Id's of the controls inside the GridView except for validators.
I am using a custom validator to call a javascript function for validation. My problem is that I need to be able to change the error message dynamically. Here is the code:
<asp:CustomValidator ID="CustomValidator1" runat="server" ClientValidationFunction="fcnValid1"
ErrorMessage="" Display="None" ValidateEmptyText="True">
</asp:CustomValidator>

I have one textbox, in which I want allows to enter value like
1, 1.5, 2, 2.5, 3, 3.5, 10, 10.5....
That means user can enter only 1 digit after decimal and it is restricted to .5 only, not .25 ot .34 or .75
Let me know how can I do this?
I have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?

When it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?
I have a validator callout extender that works, it shows the callout box. But, it does a postback. It didn't do a post back the first time I clicked the button but it did for subsequent times. I read on the AJAX site that a custom validator must be used with this for it to work. I'm currently using this with a required field and regular expression validator. It works, the callout appears, but it doesn't work every time with out the post back.I posted this to see if there is a way to get this to work with a required field and regular expression validator, with out using a custom validator. I'm using the newest release of the toolkit, so I thought the documentation may be old, since the callout is appearing.
