I have TextBox1 (enabled = true) and TextBox2 (enabled = false) in my WebForm on loading. Both are validated by means of a RegularExpressionValidator.
How can I set TextBox2 enabled = true ONLY AFTER (!) the text inserted in TextBox1 has been validated and accepted as valid ?
Can this be done on client side exclusively or is some code behind absolutely necessary ?
I having a two radio button. When the second radio button is enabled, a text box which accept the email id will appear. I am validating the Email using Regular expression validator.
When the second radio button is clicked, and I enter the invalid email id so that it shows me and error. But when I click the first radio button, it is showing the save validation. I need this to not show the validation when the first radio button is clicked and invalid email id is there in the text box.
I would like to use validation to check the length of a textbox entry (character length) when the textbox loses focus. how I can do this?
View 41 RepliesI'm using 3 text boxes for allowing user selecting different ranges. I want to perform below validations on three text boxes.
1.User should enter a value (i.e. a valid number,doesn't allow to enter zero,decimal numbers and negative numbers) in 1st text box.
2. 2nd text box value should be greater than 1st text box.
3. 3rd text box value should be greater than 2nd text box.

using c# I am entering two types of string in a text box for eg "so-123456" or "12345678" only this two formats are allowed to enter, when i enter only 12345678 i.e, without "so" next textbox in that page should be enabled, if i enter "SO-123456" textbox should be disabled. without any click event i.e, while entering text in 1st textbox if it contains "so" textbox2 should be disabled, if textbox1 contains only integer(123456) textbox2 should be enabled.
View 1 RepliesI have a checkbox and a textbox in a GridView (for every row), and I'd like to be able to write some javascript that would enable and disable the textbox depending on the state of the checkbox (checked or unchecked). I guess I'd have to give JS the row index somehow.
View 3 RepliesI am trying to enable/disable textbox when checkbox is checked (enable) or unchecked (disable). WIth the piece of code i have nothing is happening once the checkbox is checked/unchecked.
Here is what I have:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="AssociationInfo.ascx.cs" Inherits="Administration.Modules.AssociationInfo" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<script type="text/javascript" language="javascript">
function enableTextBox() {
window.onload = function () {
var check = document.getElementById("chkAssociation");
check.onchange = function () {
if (this.checked == true)
document.getElementById("txtAddress").disabled = false;
else
document.getElementById("txtAddress").disabled = true;
};
};
}
</script>
<div>
<h2>Association Info</h2>
<br />
<asp:CheckBox Checked="false" ID="chkAssociation" runat="server" />
<asp:TextBox ID="txtAddress" Text="Test" runat="server" />
</div>
The code is in web user control. Could that be reason why is not working correctly?
radiobuttonlist (Yes and No)
if yes, textbox should be visible
could we do it using ajax and without using autopostback property?
Added <Body onkeydown = "return(event.keyCode!=13)"> into a VS2008 masterpage. Did this to disable the Enter key from basically doing a button click event. The code works great, however, we use multiline textboxes that were accepting Enter to do a newline in the textbox. Now the multiline textbox does nothing when Enter is pressed. Is there an override that would work on a single form that loads behind the master page? Ref: your Disable Enter key in TextBox to avoid postback in ASP.Net.

This control is used multiple times on one aspx page. The issue is that each time an instance of the control is validated due to a text change any prior error messages are cleared from the validation summary. I want the validation summary to maintain prior error messages during the postback.
Why does this markup ...
<asp:TextBox ID="TextBox1" runat="server" CausesValidation="False"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegExValidatorTextBox1" runat="server"

I have used validation in a couple of pages in my new MVC app, and I noticed that whenever a textbox is invalid, it's width and length will usually change slightly when the validation error is displayed on the page. I have been using this css :
[Code]....
I am wondering, does everbody get this, or is it just me?
how to validate
1.TextBox should not accept the DateFormat
2.Should not accept only numbers
3.it's accept combination of numbers and alaphabets.
Is there a way to disable request validation for just certain textboxes instead of the whole page? I'm using Server.HtmlEncode/Decode because users are legitimately using < and > characters but I don't want to use ValidateRequest="false" on the whole page because someone could add a textbox later and forget to escape the input in which case I would want validation to occur so the error would be discovered rather than be vulnerable to html injection. It seems like there has to be a simple solution but I'm not having any luck finding it.
