Removing Readonly Attribute From Textbox Using Client Side Code

Mar 5, 2010

I have a multiline textbox that by default, is set to ReadOnly. I would like a button on the page to change the control to allow it to be edited. I would like this code to run on the client side because the page renders slowly and I'd like to avoid the post back.

The problem I'm having is the javascript code that I wrote to remove the readonly attribute appears to have no effect. I posted a stripped down example that illustrates the problem for your review.

AJAX :: Readonly Textbox Value / Why Value Is Available When Use Code Behind Attribute Add

Feb 17, 2010

I have a TextBox in my page

<asp:TextBox ID="TextBox1" runat="server" ReadOnly="true"></asp:TextBox>

I am not able to get the changed value ( I have attached a ajax calender with this textbox)

in code behind because it is readonly

I can do this using TextBox1.Attributes.Add("readonly", "readonly"); or I can get the correct last value using Request.Form[TextBox1.UniqueID]

Why value is available when we use code behind attribute add

Jquery - Removing Items From Dropdown List (client Side)

Feb 10, 2011

So I have a number of dropdown select list controls populated as part of a repeater. They might contain overlapping data, meaning that the first d d list control will have selections:

a
b
c

Second one:

c
d
e


Third one:

d
e
h

and so on.

So what I would like to do is to srart removing the duplicate items from the reset of drop down controls once the user starts selecting those. I intend to use jQuery for this.

How To Execute Serverside Code In Parallel With Client Side Code

Aug 2, 2010

I have a web app that needs to do two things at the same time. After a user clicks a button on the site, a javascript function needs to execute and while thats working I need the server side code for the button click to execute without waiting on the client side to finish.

To be more specific, the client side function takes about 23 seconds to complete, and while that is running the server side code promts the user for printing a document. So I need the javascript to run "in the background".

How To Run C# Code On Client Side In A Web App

Jan 7, 2010

I have code on my server which works very well. It must crawl a few pages on remote sites to work properly. I know some users may want to abuse my site so instead of running the code which uses webclient and HttpRequest i would like it to run on client side so if it is abused the user may have his IP blacklisted instead of my server. How might i run this code client side? I am thinking silverlight may be a solution but i know nothing about it.

Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked

Nov 23, 2010

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)

<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...

There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)

<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...

There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

How To Use Client Side Code In Visual Studio

May 28, 2010

I am a quite new to web development and I am trying to do some small form updates without causing a postback. For example making a control visible when a drop down list is changed.

I have so far come across some features that achieve this like the RequiredFieldValidator inside an update panels. However, these are specific to a single task.

What are my options to achieve these client side updates in Visual Studio? At the moment I don't know any JavaScript, so I would prefer another solution if it exists.

Web Forms :: Client Side Variables In Code Behind?

Sep 1, 2010

I have a question, I am writing a user tracking class that needs to obtain the screen resolution of the user. I have the javascript all written and it is working along with a hidden variable ( used to set the javascript vars so I can access them server side ). What I am running into is when I try to access the value of the hidden variable on Page load it's not there, but If I cause a post back I can get it. How can I access this data on page load? There is no guarantee that the user will ever cause a postback, some users just look at the home page and leave.

And here is where I add the Client Validation to the customer validator in the code behind.

The validation is if there is a value present in the first text box then the second text box is required.The page throws an error when the validation should fail, but if I ignore the error the validation works correctly.Do I need to move my javascript to the code behind as well?
