Javascript - Check Result Of C# Validator Clientside
Dec 28, 2010
I 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.
I have a required validator that I check a textbox clientside, but then on post I check the database for values that have been used. I want to show the error in the RequiredFieldValidator when it post back. How do I do this?
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:
I would like to make a div id="CompanyPanel" on click event of each checkbox according to the following condition
visible if any of the checkboxes are checked.
hidden if all of the checkboxes are unchecked.
I am planning to use jQuery since I am selecting by class name. I could do it with jQuery.each on the class='company' by checking each for a checked flag.
Let's say I have a function that takes a string. That string contains the fully name of an enum type (e.g. "MyCompany.Area.AotherNamespace.MyEnum").
How could I create an array of strings (or List<string>) whose elements are the values of MyCompany.Area.AotherNamespace.MyEnum?
Is that even possible?I'm basically trying to serialize an enum type serverside and then output it in clientside JavaScript so I don't have to define an enum in two places--in my C# and my JavaScript.
I have three views inside a Multiview How to activate one by one view means I Just want to change the Active View Index of the Multiview using javascript in ClientSide How can i do this?
Why am I getting this error? I'm trying to do a calculation on my GridView2 and I'm using clientside javascript. I need to add the onkeyup attribute. How do I do this?
Code Behind:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load CType(GridView2.FindControl("TextBox13"), TextBox).Attributes.Add("onkeyup", "calculateSubTotal") End Sub
I'm making a website in ASP.NET 4.0 where I make use of the RequiredFieldValidator control to validate a wizardstep.It works perfectly with Javascript enabled, but when I turn it off (in my Firefox) it just goes to the next step.We don't do a Page.IsValid check, but we don't do much on the "next button clicked" event either.Certainly not something that is forcing it to go to the next step.
i need to check , client side, if both email and phone number are empty .The textboxes are template columns of a detailview. I've added a custom validator for each textbox (one inside edit template, one inside insert template, etc . . ) each custom validator call the same javascript function . So the problem is : the custom valiator is activated only when at least a charachter is put into a textbox and i want to check if both textbox are empty .
I have asp.net form having 4 check boxes. not check box list. these 4 check boxes having the ValidationGroup property with same name say "chkValied". I have added Custom Validator there. now want to check at least on check box should be check out of these.
I want to be able to get specific website thumbnails and display them in an ImageBox. The easiest I've found is using a web service. Unforntuantely, most of these services don't allow me to just attach a URL. If I could, then I would just assign the URL of the ImageBox as the URL.
Instead, they force me to use JavaScript like this:
I'm still learning MVC. I would like to be able to display a list of items in a dropdownlist and then when I select one of those items invoke a new action that will process the selected item.
I can create the DropDownList but I cannot figure out how to return the selected item back to the controller. Below are some snippets from my code. The first shows the Index Action which just gets a list of pathnames which I call widgets. The second is an action which I'd like to use to process the selected file.
The third section is the view in the Index.aspx for the HomeController's Index View.
I have read several articles that show how to do this using JQuery or Ajax, but I'd like to do it without using either so that I can run this on a mobile browser that has no javascript.
I have a GridView in a div wrapper, there is some row headers along the left side that need to be always visible. This all works so far, but I need the wrapper to have a variable width to fit the browser size.
I got the desired width of the wrapper based on the browser width using some javascript but I can't figure out how to set this width as the wrapper.width.It doesn't have to update the wrapper width after the page loads or check for browser resizing.
my poor attempt at diagramming:
| |column headers | | R |--------------| | O | gridview data | | W | | | | this part | | H | will scroll |<---> | E | while the | | A | Row headers | | D | stay there | | E | | | R |______________ | | S | scroll bar |
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 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.
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.
