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

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.

I have a textbox that is set to readonly so users won't try to type something in it. It is then populated when a treenode is clicked. I want to validate what is in the box after it's populated from the treenode click but if i have it set to readonly, in the codebehind it shows up as an empty string. if i take the readonly off it shows up populated. what would you do about this?

I've got some textboxes in a panel, that I want to disable client-side upon radio button selection. I've got it basically working - but I discovered that javascript's control.disabled = true still allows the user to type in the textbox. So I've moved on to control.readOnly (in addition to disabled) - that seems to give the result I want.
Problem is, setting readOnly at the panel level doesn't seem to propagate down to the contained controls (the textboxes). I still have to call textbox.readOnly directly in order to get the no-typing-allowed result I need. And this makes the whole panel-concept useless for me in this instance.
Am I doing it wrong somehow, or is this just the way panels work (i.e., can only make textboxes readOnly by directly manipulating its property)?

"How to: Customize the ASP.NET CreateUserWizard Control" [URL]
In the final example, a wizard step, "CreateUserWizardStep0", is used to validate the username as unique before proceeding to the createwizardstep that collects the remainder of the user's registration information. In order to keep the user from changing this username on the next screen I have set the textbox for username to ReadOnly=true. However, this changes causes the registration to fail without ever executing the method "CreateUserWizard1_CreatedUser."

I have a frame with several radio buttons where the user is supposed to select the "Category" that his Occupation falls into and then unconditionally also specify his occupation.If the user selects "Retired", the requirement is to prefill "Retired" in the "Specify Occupation" text box and to disable it to prevent it from being changed. The Specify Occupation text box should also no longer be a tab stop. If the user selects a radio button other than Retired the Specify Occupation text box should be enabled and once again and the Specify Occupation text box should once again be in the normal tab sequence.
Originally, I was setting and clearing the disabled property on the Specify occupation textbox, then I found out that, upon submitting the form, disabled fields are excluded from the submit and the REQUIRED validator on the Specify Occupation textbox was being raised because the textbox was being blanked out.What is the best way to solve this? My approach below was to mimic a disabled text box by setting/resetting the readonly attribute on the text box and changing the background color to make it appear disabled. (I suppose I should be changing the forecolor instead of teh background color). Nevertheless, my code to make the textbox readonly and to reset it doesn't appear to be working.
function OccupationOnClick(sender) {
debugger;
var optOccupationRetired = document.getElementById("<%= optOccupationRetired.ClientId %>");

I have a webform that accepts a date range to generate PDF reports. I had to place a PostBackTrigger on the updatepanel and assign the button thaat generates the reports because the Response.ContentType is being set to "application/pdf".
The problem is I am updating the textbox value to the count of clients that are left out of the report generation in server side code, the count always come back as 0. I have tried multiple panels with no luck. The textbox is in the main updatepanel with the print button and that still does not work.

I ran into a strange issue with the AJAX MaskedEditExtender control, the extender is used with the Mask="99/99/9999" and MaskType="Date". Initially when the page loads the textbox was set to readonly using textbox.Attributes.Add("readonly", "readonly") in the codebehind. After the page loads if the user clicks on a certain button it would change the textbox to editable using javascript code: textbox.readOnly = false. The strange thing is after that if you start typing in the textbox you can see the entire mask
(__/__/____) shifting to the right as you type. For example it looks something like this: 09__/__/____ instead of the normal 09/__/____.
If the textbox was never set to readonly in the first place this behavior won't happen. So it seems something got messed up when changing from readonly to not. I was able to reproduce this in a barebone aspx page with just the textbox, the mask extender, and a button that when clicked turning off the textbox's readonly. Anyone knows how I can fix this?

If I declare a DIV and set it to runat server I get a clientmode attribute which I can set to determine what the ID comes out to be on the rendered page. I need to do this for a drop down and a textbox but clientmode isn't available on those controls. What can I do? I don't want to do some crazy workaround. If it comes to it i'll just do an auto postback and do what I need there.
