this hidden input is used by a star rating control. the user gives a star rating of 1 to 10 by clicking on the stars and some javascript detects which star was clicked and fills the input with the corresponding number.
I want to use a RequiredFieldValidator to ensure that the client has selected a star and if not return an error message to my validation summary.but the validator seems to be throwing an exception. How do I do this?
Since I'm new to coding and I'm trying to understand why here is a little more detail on the question.If you have a text box and you are limiting the input to say 2 charactrs do you really need to validate the input further? What I have is a text box that has a max length of 2. Is there a security reason to add a validator to the textbox. I should add this is in Asp.net.
Dispite what the topic subject says, I really want the opposite. I panel with a form and validations that's hidden. I also have another form that I'm trying to use on the same page, but the page won't validate because of that hidden form. Is there any way around this? Can you tell the brower NOT to validate just those hidden fields?
I want to create input inside gridview, the id of the input is set by me. I do want to use HiddenField control because when generating the id of the control, it will set id to gridview_ctrl.....
The input looks like this: <input id="myid01" value="myvalue" type="hidden">. Note that id is generate by me in the code behind.
I have a textbox called "tax rate" which I need to validate the input... The only thing I need to ensure is that the value entered is a number (decimals ok of course). eg. the input might be "8.75" How do I write the validation expression?
I want to integrate paypal inside my shopping cart. For that it requires a html form to be embeded inside .aspx page with the action to paypal and method is post. Inside that form there are some hidden input filed. I want to assign one of those hidden field's value from server side code so i need to access that filed from server side. But how? Here is my form:
I've set up a page that uses JavaScript to hide or show rows in an HTML table, depending on the state of a checkbox.
So far, so good. But this is a data entry form and some rows include validation controls. However, it appears that if I hide a row (using JavaScript: style.display = 'none') that contains a validation control, the control still validates on an attempt to postback.
way I can do this but have the validation controls not do anything if that row is hidden?
I have 1 drop down, 1 text field and 1 command button i.e. "Search". Dropdown contrains following values
Type1 Type2 Type3
In textbox user will enter numeric or alphanumeric value
Here I want to check if 'Type1' is selected so user can enter only numeric value between 1000 and 2000, otherwise display some message "Entered value is not valid for "Type1". I want to display this message thru required validator error message property
If user select 'Type1' and 'Type2' then user can enter any alphanumeric value other than 1000-2000 numeric range.
I want to implement thru Search button or once user leave the textbox after entering value. Here I want to display message.
I have static html paypal buynow button that works great, but it's static.
[Code]....
But it is possible to change the values for the hidden inputs from .net codebehind code? I found this post which takes a different approach of sending these hidden fields instead as a query string to paypal. Not sure I like that though as would this not possiby explose some of those fields like the return page?
Basically what id like to do change the important parts of the button and info I'm sending to make it dynamic.I know I can do something like this in the markup, but that would mean having to fetch data mulitple times was hoping I could somehow adderss the field values directly in the codebehind. Or possibly dynaically generate and insert the entire changing input type fields from the codebehind
Possible to add them with something like this: myform.Attirbutes.Add (???). If so how do I contruct these input types in .net?As far as return logic security, I've tested that it's solid, i just need to automate the button process so I don't have to create a buy now page and button for each product.
This is probably embarrassingly easy, but I've having problems getting this to work.
On ResidentAddress.aspx, I have 2 user controls (AppName.ascx and NavButtons.ascx). When a textbox in AppName.ascx has focus, I want to update a hidden input field on NavButtons.ascx with the value of "TRUE". In the codebehind page for NavButtons, I want to see what the value of this hidden input filed is.
This is what I have so far:
NavButtons.ascx <input type="hidden" id="IpChangeFlag" name="ChangeFlag" runat="server" value="FALSE" /> AppName.ascx <asp:TextBox ID="txtFirstName" runat="server" onFocus="document.getElementsByName('ChangeFlag').value='TRUE';"> NavButtons.ascx.vb If IpChangeMade.Value.Trim.ToUpper = "TRUE" Then MyValue = true End If
I am unable to change the value of ipChangeFlad. It always has the value of FALSE.
I'm working with jquery.ajax() I'm getting a object and I use jTemplate to write the html. My problem is now that I need to place the id of the object in a input hidden. I have no idea how I should do this. I tried to do a <script> in the template.htm with jquery to place the id in hidden but with no luck.
And the top of the Download.aspx code behind looks like this
Code: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim ctx As HttpContext = HttpContext.Current Dim response As HttpResponse = ctx.Response Dim sFile As String = "mit-license.txt" ' Request.QueryString("filename").ToString
[Code] ....
I could not find the INPUT value - where does it pass in? I checked the "sender" and the ctx objects and could not find it... I hardwired the mit-license.txt filename to prove that the download works...
I have been trying to set the value of a hidden input by using Javascript and then access the value from within my C# codebehind. When I run the code that is copied below, the value that is assigned to assignedIDs is "", which I assume is the default value for a hidden input. If I manually set the value in the html tag, then assignedIDs is set to that value.
This behavior suggests to me that the value of the input is being reset (re-rendered?) between the onClientClick and onClick events firing.
I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.
I'm using V.S. 2008 and asp.net MVC. I have a form in this page that user selects various items from Select controls. I then construct a string varible that contains each selected element's id a hidden input control that holds this information. How can I pass this variable (and it value of course) to a Controller Action? I am using regular Html Form and the Submit button.
In the following code you see the "ResearchInterests" is the one that holds the string but I can't even reference it in my Controller action, Search. How can I correct this?
I was planning on using a custom validator but it seems that the validation function only gets called when something is written on the textBox i'm using has the 'control to validate'. Now, that doesn't work for me since I want to show an error message when both text boxes are empty. Is there a way to make the validation function to be called with, for example a postback? Or is there any other better approach to this case than the custom validator?
I am always thinking about validation in any kind on the webpage (PHP or ASP, it doesn't matter), but never find a good and accurate answer. For example, a I have some GET-Parameter, which defines a SQL query like DESC oder ASC. (SQL-Injection?) Or I have a comment-function for user, where the data is also saved in a database.
Is it enought to check for HTML-tags inside the data? Should the validation done before adding it to the database or showing it on the page? I am searching for the ToDo's which should be always performed with any data given from "outside".
VS2008 c#, asp.net 3.5, ms sql 2008How do I validate user input in TextBox inside a FormView [Insert Mode] with MS SQL 2008 Database?* FormView #fvInsertProjectInfo* TextBox #txtProjectNameCurrently, user could insert a new project using the FormView, but will only be found out that the project is already existed when pressing the INSERT button. To make it more user friendly, I would like to check that the database does not contain a record of the project the user trying to insert (by comparing value in txtProjectName with the Projects table in the database)
