Web Forms :: Can Validators Automatically Prevent Database Entry If Triggered

Nov 8, 2010

When I use RequiredFieldValidator inside a DetailsView control field template, it automatically prevented DetailsView from inserting new records into the database, when triggered. JavaScript was disabled.

I'm a bit surprised and I'd like to know whether this is caused by the validator or is there a built-in feature in DetailsView that prevents database from being updated if some validators on the page are triggered?

If so, how is it possibly implemented (e.g. inside when eventhandler)?

Web Forms :: Required Field Validators Are Being Triggered By Other Buttons On Page?

Jul 15, 2010

I have created a form with several textboxes and a dropdown list and assigned a required field validator to each of them. I also have a master page with several links to other pages, some made using <a href=..> and some linkbuttons. The problem I am having is that when I click the linkbutton links they do not redirect to the proper page, rather they trigger the validators for all textbox fields and display the validator characters next to each textbox (and the dropdown). When I fill out the form, those links redirect properly. The links created using <a href=..> do not cause this problem.

Postback Not Being Triggered On Button Click When Using Validators

Mar 22, 2011

Server Click event is not being triggered when I click on the "LookupButton". The weird part is that this code works on our Dev server, but not QA. If I get rid of "LookupValidationGroup", from the Lookup Button ValidationGroup property, the page does postback, but then my validators do not work. I could explicitly do the validation on the Server Side, but dont think I should need to.

No errors are being displayed. I also reinstalled .net 3.5 using aspnet_regiis -i command.

Web Forms :: RegularExpressionValidator To Prevent Numeric Entry Not Working

Jan 9, 2011

I have a 'City' TextBox on one of my web pages but people from many European countries sometimes prefix the city name with the postcode instead of putting it in my dedicated 'Postcode/ZIP' TextBox. I have therefore just added a new RegularExpressionValidator to this TextBox. Its purpose is to prevent the user from entering any numeric characters but allow everything else. After browsing for a suitable regex (I am not a regex expert), I found the following code that was claimed to do what I want.

ValidationExpression="^D$"

Unfortunately, the RegularExpressionValidator does not work as expected. Instead of just rejecting numeric characters it appears to reject everything! Where might I be going wrong?

Web Forms :: Prevent Duplicate Entry Into Aspnet_profile Table Through CreateUserWizard?

Jul 29, 2010

Is it possible to setup the CreateUserWizard to check for a duplicate entry in the aspnet_profile table (for a custom field) before the new user is created? For example, if I added a phone number field and wanted to make sure nobody else could create an account using that same phone number if a user already has an account with that phone number in the aspnet_Profile table's PropertyValuesString row?

How To Prevent The Entry Of Two Characters Together

Feb 16, 2010

I want to prevent the entry of two characters together but I want the user to be able to enter one or the other as well as use the enter key. I would like to use a white list instead of black listing characters. The regular expression also needs to support a min and max length. I'm doing client side validation using the asp:regularexpression control. I do not want to have to do server side validation unless that's the only solution to this problem. Has anyone else run into this?

Here is the regex I'm currently using:

(?!.(&#))^[a-zA-Z0-9!@#$%^&_=+~''"";:,
.()?-]{1,1000}$

I'm using a asp.net textbox that is set to multiline so I have to allow for
and or what's the point of using a multiline textbox :)

I want to keep the user from entering &# together but allow them to enter text with & or # in it and allow all of the characters a-zA-Z0-9!@#$%^&*_=+~''"";:,
.()?-.

A valid text entry would be as follows:

I have a question about my order. The order number is 12345.

An invalid text entry would be as follows:

I am trying to keep the user from entering &# in the textbox, but I want to allow them to enter & or #.

I have several text boxes in an ASP.NET Web Form. I want to ensure that users are not entering HTML into those text boxes. However, I'm not sure how to prevent HTML from being entered. Because of this, I decided that I want to only allow alphanumeric characters, spaces, exclamation point, sharp sign, dollar signs, percentage signs, carets, stars, and left and right parenthesis. I'm omitting the ampersand because I do not want them entering something like "<script&rt;..."

Web Forms :: Connect Controls To Empty Database To Allow Data Entry?

Mar 15, 2011

I have a simple web form with controls such as test boxes, radio buttons, etc. I also have an empty SQL database created from within Visual Studio Express 2010, in the same project. I want to be able to open the web form, enter text, for example, in a text box, and have it saved in the corresponding field in the database. Ditto with the choice I make from a Radio List box, etc. Is there a simple way of connecting a control on a form with a field in the SQL database? I've tried a number of ways but can't seem to do it, though I realise it must be simple. I also think the control need to be in data entry mode, if there is such a thing, rather than automatically looking for data within the database to display (there is none). I'm new to SQL server and ASP.NET in general, though I've been through a lot of the excellent video tutorials etc.

Web Forms :: Collect Customer Complaints And Stores Into Database - How To Entry Form Works

Dec 16, 2010

I am writing an application that collects Customer Complaints and stores them into a database. I want to keep it simple so that the Managers without much web knowledge can use it. This is how my Entry Form works. The Manager selects the name and id of the staff by choosing a location. This loads ids and names of the Staff in that location from the database. Then the Manager rates the complaint based on the severity and enters the comments. I was able to use Session objects to get all these values from the Entry page to the Confirmation page so the Managers can check again. This is where it gets tricky. If there is a correction they have to make by trying to go back to the Entry page, the values are lost (esp. Drop-down ones).

Display An Image Based On Database Entry?

Jan 13, 2011

I am really new at this. I have a site that I would like to display a certain image (a colored flag) based on an entry in the database. I have a folder called flag_images, I'm using VB, and MSSQL Server 2005. I have never done anything like this. There are 4 images total. They are green.gif, yellow.gif, red.gif, and black.gif. The database table is called tblflag. There are three columns. ID (int), time_set (datetime), and flag_color (nvarchar).

I would like to display the green flag if the column flag_color is equal to green and so on for the other colors. Only one flag will be displayed at a time.

DataSource Controls :: Store A Textbox Entry To A Database And Then Display It?

Jan 31, 2011

I have to create a simple application which scans, displays and stores the info from a barcode. I have been able to sort the scanning and display part of this application but I need to know how to store the infromation entered into a textbox to a database and then be able to display the stored data as a list at a later stage.E.G. Once the "STORE" button is clicked, the information/text within the textbox is stored to a database. Once the "VIEW STORED DATA" button is clicked, the stored information in the database is displayed as a list.I am a complete beginner when it comes to creating web applications using asp.net. Also, the type of database to use (i.e. sql, wamp.etc) and how to link it to my application is also puzzling.
