MVC :: Value Of Disabled TextBox Does Not Submited To Server?
Mar 10, 2011
why the value of disabled TextBox does not submited to server?i have text box to input date(year, day, month), and decide to inforce the user to insert date throgh datepicker jQuery control, so i have disabled the textbox, but the value does not submitted till i have remove the disable attribute(i dont want to lit the user to insert the date manually then i have to do exception handling to the wrong input.. i can not gess what he/she input)
I am trying to make ONE thing work. The form currently have TWO Textboxes and ONE CustomValidator(connected to the first textbox). I simply want once I enter less than 4 characters in the first Textbox and tab out to the second Textbox and if Javascript is DISABLED then the server side code should stop me. I can achieve what I am trying to do if I use a button but I need to do it in the fashion I am trying decribing because if I have for example 20 textboxes on the form I want the user to see after each data entry that his validation was successful or not. Here is a sample of my code.
1) login and send username,password, machineID and a rand string to the server 2) check the machineID whether it exists in the table.
Problem is the checking machine procedure:
select MachineID from computer where MD5MachineID=@MD5MachineID2 and SUBSTRING((master.dbo.fn_varbintohexstr(HASHBYTES('MD5',MachineID+@RString))),3,32)=@MIDST
RString,MD5MachineID2,MIDST are submited by Login MD5MachineID is stored in table.
I need the check if MD5(MachineID+RString) is match the MIDST (submited).
Now the situation is :
if RString is a fixed string(not a variable).like 'abcdefg', the MD5 is correct.
if I use the RString (submited value as a variable), the MD5 is incorrect.
i m using one disabled textbox in my page .it is looking disabled in mozilla firefox but looking like a simple textbox in IE. what to do to give it a disabled look in IE also.
n a page with textbox control, lets say this textbox is disabled on server side page load.What would happen if a javascript tries to set visibility of the textbox to false ?dit:Can the textbox be hidden by javascript even though it's disabled ?
I have a repeater which viewstate is disabled, inside i have a textbox and a submit button. Before disabling viewstate i could get the text from the textbox in the submit buttons onClick event. But now it doesnt seem to work.
I dont want to enable viewstate on the repeater as my site get really heavy then. How can I get the value form the textbox when I click the submit button? using .net 3.5
[AcceptVerbs(HttpVerbs.Post)] [ValidateAntiForgeryToken] public ActionResult EditLogin(LoginForm post) { return View(model); }
post.Username will be blank, all other properties bind correctly, but if I change @disabled="disabled to @readonly="readonly" the username binds properly and everything works. It looks like model binding ignores values in disabled fields. Is their a way around this? I still need the field's value to bind to the model. I can use readonly but would prefer to use disabled so it is visually apparent to the user that they cannot edit the value of the field.
if booking closed column values is equal or more than textbox1 text then the book button in gridview will be disabled for each gridview item whose booking closed time is greater and equal to textbox1 time ..
When TextBox1.Enabled = false; it has a gray background in FF3, but no change in IE8 or Chrome. So it's harder to tell if it's disabled or not. Is there any more general way to make the disable textbox rendered more consistent on a top-level? So I don't need to change this for every page or every website?
However I need to make a javascript function that on page load clears all textboxes. then when a single textbox is clicked all other textboxes are disabled until the user has finished and hit the "save button", then all textboxes are enabled again.
I am new to ASP.net but i used VB a lot back in days, i am working on a site and i want to create form so the data from it could be submited to the email. i have put some stuff together but need some corrections. It feels like having brain shut down.
[Code]....
And here is code that contact the Email server that i have found in this forum on diffrent thread.
I have a couple of textboxes (actually a set of pairs of textboxes) where users can either enter a value or a percentage of a value but cannot use both. So in any given time some of these textboxes are disabled depending on which option the user chose.
For the textboxes representing percentages, there is a range validator to make sure only values from 0 to 100 are entered. If user selectes to enter datanot in percentage form, the percentage textbox gets filled automatically based on the value user enters. So if the total is something like 8 and user enters 2, the corresponding percentage textbox gets filled with 25% (minus the % sign).
However, the vaidation fails as if there is nothing there, persumably because the textbox is disabled. How do I get around this?
After witnessing some strange behvior I'm confused about ViewState again :/
My understanding was a textbox needed to have "EnableViewState" set to true otherwise when the you postback the fields contents would disappear.
That's not happening, I created a textbox and button and a label.
The button was set to copy contents of text box into the label when I pressed it.
I did and the text was populated into the label and remained in the textbox?
This was inside an UpdatePanel and the page itself has a MasterPage, so that might have something to do with it, but I have about 50 textboxes on this page all with viewstate=true on, so I would really like to know what controls need to have enableViewstate=true in order o function properly.
If a control is disabled (enabled = false), will the validator controls associated with it automatically know not to carry out validation?i have a checkbox and a textbox, if the checkbox is checked, the textbox is enabled, and has to have a value, where i used a required field validator.but if the checkbox is not checked, textbox is then disabled, however, the validator controls still seem to be trying to validate the disabled textbox.so is there a way to disable validator according to textbox's state? such as textbox.enable = true? seems like causevalidation method requires multiple button, owever i only need one...
In text box onchange i call the javascript function
for calculating txt5 value
i.e.
in javascript method,
txt5.value = parseFloat(txt1.value) + parseFloat(txt2.value) + parseFloat(txt3.value) + parseFloat(txt4.value); and text box txt5 enabled=false,autopostback is true
protected void txt5_TextChanged(object sender, EventArgs e) { // here based on txt5 value i getting records from database and doing some calculation and display those value in txt6,txt7 }
The problem is the textbox txt5 can;t post back when text change from JavaScript function.
How can I do postback when text box value bind from JavaScript function and enabled=false.
I have a user control with a label and a field. I add the user control dynamically to a page at run time. There could be many user controls which are built dynamically from data I get from the data base. The data describes the label name and if the text box should be completed.. ie is it required. I have a submit on the main page which has a validation group.All the validators on the user controls have the same validation group. So far so good I hope.
The user control has a RequiredFieldValidator for the text box and looks all like this. The validator is enabled by default.
When I dynamically load the control I check a parameter to tell me if the field is required or not. The paramater is from the database which represents the control that I am about to draw. If the Field NOT a required field I disable the validation in the page_preRender.. also tried it in load.
So far so good. This all works on the client side validation for only the user controls with the Display Required set to true, leaving the Validator enabled.however on posting page from a submit button which I have wired to the same validation group as the user controls, I check the IsValid on the submit and if its false I dont save anything. But when the page re-renders on the client.. I have error messages on all the user controls, saying that they are required... even though I disabled some of them that where not required. the View state is default on the control which I assume to be on.
I also tried not redrawing the controls with the validators, by enclosing the code in a if(!IsPostBack)
why the validators fire when they are disabled on the first page load but dont get disabled on the postback.
This code does indeed disable the client side validation, but unfortunately it does not disable server side validation. I have a way to check to see if I need to validate them or not on the server but it's a bit complex and requires duplicating some code that is used later on to calculate the total due. I use that check and disable the validators in Page_Load and sure enough the validation does not occur. to get these validators disabled on the client & server from the client side?
Form1 is for the administrator. It has 5 fields. Field1 has a value for which the other values give details about it. This 5 fields are stored in a table. Form2 is for a user and its a data entry form. This forms has 12 fields. Each label in the form2 corresponds to the value of Field1 in form1. If suppose the admin fields 10 times the form1. The 10 labels of form2 are filled with values of field each time. The above is what I want to achieve. Also the two text box corresponding to the remaining two labels should be disabled for user.
I am in the process of developing a feature rich website with vast use of jQuery. My biggest concern is that I will not be able to reach a percentage of my users because they will not have Java Script enabled or will be using a platform that is not compatible with jquery. I know that I can use a simple java redirect from within the html page itself but this does not seem like a decent resolution to the problem as I would rather the script be run on the server side not from within the html page itself.
Is it possible to configure IIS, Apache, or Linux to run a script that redirects specific browsers, platforms, and settings to another html page before the html request is made? It does not seem sensible for the default index.html page to download initially before a second request is made back to the server for the index1.html page.
I need to redirect certain platforms (IE 6 for example), and browsers with java disabled to a separate website that does not have jQuery functionality.
I have DotnetNuke loaded in Visual studio 2010. The 'use custom server' option under 'Start Options' is disabled. Why is it disabled?
What does 'Use Default Web server' default to? How do I change what the default is? In earlier versions of VS i was able to switch between IIS and the internal web server (Cassini). Now it's more confusing in VS 2010!
Would the project type, Web Application Project vs Web Site project, affect the setting?
We have recently had some security issues with our web app where users have actually gone into the IE debugger tool and enabled a "Submit" button and saved data they shouldn't have. So...my question is....is their anyway to prevent this from happening?
I'm trying to disable a checkbox depending on whether an xml value contains the word disabled but I'm getting an error as follow. Does anyone know how I can accomplish this or see something wrong with how I'm doing it? The XML value is either blank or contains the word "DISABLED"
error:

My web app (asp VB 2005) uses Windows authentication. If the user isn't part of a specific AD security group they don't get to edit the data; instead I redirect the user to a read-only page.The program works fine in the IDE.I published the web app to my laptop and Disabled anonymous access. When I ran the program I got redirected to the read-only page. I added a write event to the application event log to see what was going on, and found that the WindowsPrincipal.Identity.Name contained my laptop's ID, not my user name.I reassert: anonymous access is disabled in IIS and the web.config file has Windows Authentication.
