Web Forms :: Validate Content And Length With Regexvalidator?
Jul 23, 2010
I have a two-character field for US State. I add a RegularExpressionValidator control to validate the input using
ValidationExpression="[a-zA-Z]{2}"which works to validate the content when something's entered, but it doesn't catch if someone just leaves the textbox blank.
Is there any way to validate within the same regex to catch an empty textbox?
Can any one let me know "How to validate the length of the text present in the textboxes of a Gridview using javascript".
For Example: In a page I am displaying a Gridview with textboxes inside it and a button on the page. The user need to input some text in the textboxes of the gridview and click on "Submit" button. When the user clicks on Submit Button, we need to validate the length of the text present in the textboxes of the gridview. If the length of the text inside the textbox of the gridview is less than 10 , we need to throw an error message. In the same way we need to do validation for each and every textbox inside the gridview.
I am trying to add a validation of the textbox.text.length in a FormView and prevent the insertion of being made in case the text length is not compliant (less than four characters).
In the scenario when clicking the submit button an Alert should appear with xxxx warinig text. and the Insert command being prevented.
I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs. I'm also concerned about crlfs counting as 1 or 2 characters, I'm concerned it may be different across browsers but I'm hoping ASP.NET regulates it. Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.
My form has a RegularExpressionValidator that validates user input in a textbox, like so:
[Code]....
Suppose that the regular expression I want to validate is the standard U.S. Social Security Number which is the following: ^d{3}-d{2}-d{4}$
Now, in order for user input to be valid, it MUST have the two dashes. Therefore, 123-45-6789] would be valid, but 123456789 would not. Well, if the user types in a nine-digit number (in other words, if the following regular expression is valid: ^d{9}$ ), then it's pretty obvious that this is a valid SSN and I want to have dashes get automatically inserted into the textbox before validation of the main regular expression begins. I don't want the user thinking "Hmmm... I don't know if I need the dashes or not." Just put them there if the user didn't type them in, then try to validate. How do I do this?
I am exporting a HTML table to excel by sending the data as a HTML Table string and setting the content headers:
[code]....
Is there a simple way of setting the content-length based on the size of the HTML string? Or should I just leave it blank anyway...would be nice to have the content-length ideally...
I have an asp.net web page to serve large file downloads to users.
The page is hosted on IIS7, Windows Server 2008.
The strange thing is that users can download at good speeds (2MB/s) when I don't add a content-length response header but as soon as I add this header, download speed drops to somewhere around 35kbps/s.
This is the code:
[code]...
Of course I can leave the content-length out but the user will not know how big the file is and how long the download will take...which is annoying.
In ASP.NET 4.0, I have an IHttpModule that apply a filter on HttpRequest.Filter. As the result, the content stream length is changed, and it breaks WCF with now returns 400 bad request because of the mismatch between the body length and the HTTP headers.
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.
I have a Web Method (within a SOAP Web Service) with a signature of:
public msgResponse myWebMethod([XmlAnyElement] XmlElement msgRequest)
I chose to use the XmlElement parameter after reading that it would allow me to perform my own XSD validation on the parameter. The problem is that the parameter can be quite large (up to 80Mb of XML) so calling XmlElement.OuterXML() as suggested in the link isn't a very practical method.
Is there another way to validate the XmlElement object against an XSD?
More generally, is this an inappropriate approach for implementing a web service expecting large amounts of XML? I've come across some hints at using SoapExtensions for gaining access to the input stream directly but am not sure this is the correct approach for my situation.
Note: Unfortunately, I'm chained to an existing WSDL and XSD that I have no power to alter which is why I went with a non-WCF implementation in the first place.
I will be getting data through wcf service coming form commerce server (instead of DB). Data which is coming will be in the form big html content with all html tags or may be a single line sentence. I should display this dynamic data into the placeholder in the content page (master content page). I have been trying but not able to load when the data is in the form of HTML page. html content or may be single lline of senetence.
How to I put this form on my page? The problem is I have a master page which wraps the content pages content in the ASP.net form, I can't nest the forms.
I am pasting my resume in CKEditor. My resume have some images, Horizontal line, Bullets. When I paste it in CKEditor is not displaying these contents there. Is it any other way to do it? I want to show my resume format as it is as I have on the browser.
I'm in a little bit of a bind and have some weird behavior happening with a multiview control behaving differently between two machines, and of course, the production machine is the broken one. The page renders the correct content on both machines, but if I save the html file the production machine's source is wrong.
For example, if for step 1 the output should be just the letter A, and step 2 the output should be just the letter B, and step 3 the output should be the letter C, here is what happens:
Step 1:
Production - The source and output are both the letter A
Dev - the source and output are both the letter A
Step 2:
Production - the source is the letter A and the ouput on the browser is the letter B
Dev - the source and output on the browser are both the letter B
Step 3:
Production - the source is the letter A and the ouput on the browser is the letter C
Dev - the source and output on the browser are both the letter C
Is this some issue with SessionState? I'm very new to Multiviews and by no means an ASP expert.
My AS.net code is trying to download some from the webserver but following error is coming
"The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters. "
Is there any way-out to over-come this sort of problem in ASP.net
In my application, if I do not input the value into the textfield, it will show error message: "The value '' is invalid."
However, is it possible to check one more thing: the length of the textfield? For example, it will show the error message if I input more than 10 chars? And is it possible to change the message "The value '' is invalid." to "Missing Value"?
I'm trying out the jQuery Validation plugin jQuery Docs Here is the markup of my form:
<% using (Html.BeginForm("action", "contoller", null, FormMethod.Post, new { id = "sxform" })){%> <div id="manifest"> Manifest Option:<br /> <%= Html.DropDownList("docid", ViewData["manifests"] as SelectList, new { @class = "required" })%> </div> <div id="release"> Release Version:<br /> <%= Html.TextBox("release", null, new { @class = "required" })%> </div> <div id="locale"> Localization:<br /> <%= Html.DropDownList("localization", ViewData["localizations"] as SelectList, new { @class = "required" })%> </div> <div id="label"> Label:<br /> <%= Html.TextBox("label", null, new { @class = "required" })%> </div> <div id="session"> Session ID (optional):<br /> <%= Html.TextBox("sessionInput", null, new { @class = "required" })%> </div> <div id="submit"><input type="submit" value="Build" /></div> <% } %> JS: $(document).ready(function(){ $("#sxform").validate(); });
I am using MS MVC HTML Helpers to render this form. The resulting markup looks fine. IE each input and selection element contains the attribute 'class' with the value 'required'. When I submit this form the validation does noting.
