I have a text box (txtbx1) and a button(btnadd). Id like to use a regular expression validator or of some sort to prevent the user from continuing on the form unless its a number entered.
View 7 RepliesI 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$"
Unfortunately, the RegularExpressionValidator does not work as expected. Instead of just rejecting numeric characters it appears to reject everything! Where might I be going wrong?
Is it possible to setup the CreateUserWizard to check for a duplicate entry in the aspnet_profile table (for a custom field) before the new user is created? For example, if I added a phone number field and wanted to make sure nobody else could create an account using that same phone number if a user already has an account with that phone number in the aspnet_Profile table's PropertyValuesString row?
View 10 RepliesWhen I use RequiredFieldValidator inside a DetailsView control field template, it automatically prevented DetailsView from inserting new records into the database, when triggered. JavaScript was disabled.
I'm a bit surprised and I'd like to know whether this is caused by the validator or is there a built-in feature in DetailsView that prevents database from being updated if some validators on the page are triggered?
If so, how is it possibly implemented (e.g. inside when eventhandler)?
I want to prevent the entry of two characters together but I want the user to be able to enter one or the other as well as use the enter key. I would like to use a white list instead of black listing characters. The regular expression also needs to support a min and max length. I'm doing client side validation using the asp:regularexpression control. I do not want to have to do server side validation unless that's the only solution to this problem. Has anyone else run into this?
Here is the regex I'm currently using:
(?!.(&#))^[a-zA-Z0-9!@#$%^&_=+~''"";:,
.()?-]{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;..."

View 4 RepliesI my exporting data through dataset to excel. But one column say awb no having datatype nvarchar contains long int no say : 123456789012345.

I am trying to use a cascading drop-down for data entry. However, I'm having problems because I need to set the value of the drop-downs when I load the screen. I use a stored procedure to retrieve the values from my database, and then set the drop downs in my code-behind. Then the web service kicks in and wipes them out. :( How can I set these values and utilize the cascading drop down control?
View 3 RepliesI'm developing a website for a company. They want the website to be in Arabic. So, a lot of things need to inverted in a classical website. The menu control has arrows indicative of child items. Now, I know that the menu control renders as a table. Also, I know I could change the shape and look of the arrows with a custom image by modifying StaticPopUpImageUrl & DynamicPopUpImageUrl properties.
What I need is to make the arrows appear left of the menu entry. I tried wrapping the menu control in a div with the attribute dir set to "rtl", but it didn't work. So, what could I do to fix this? Also, if I couldn't do that in the menu control and needed to create my own menu control. Are repeaters practical?
I am try to write code that will allow me to click an add button that will add unlimited text box entry on the same page.
example form:
Client Name: companyTxtBx

<table>
Employee: empTxtBx
Employee Identification Number: empIDNumberTxtBX
Employee Address: empAddressTxtBx
Employee City: empCityTxtBx
Employee State: empStateTxtBx
Employee Zip: empZipTxtBx
Employee Phone Number: empPhNumberTxtBx
</table>
Button = Add another employee button that autopostback and insert empty textboxes that is listed in the table.
I thought this would be very simple but I can't get it. I have a dropdownlist bound to a datasource in order to produce a list of items. At the top of the ddl, I want a 'NEW ITEM' entry. It's not showing up.

View 5 RepliesI'm not sure if this is the best category for this one... Might be more appropriate in the navigation section.I am curious as to the standard for redirecting users to a entry page on first accessing a website. In my case, I am working on an adults only website that requires a warning for users that the content is only appropriate for users over 18yo, as well as containing the scripts to activate several different monitor systems to prevent children from accessing the site.
I know I can use session_start to redirect and check for a cookie... but that seems heavy. Is there a better way? Something in IIS or... something I have not thought of yet?

View 3 RepliesI know that I can declare an array using the following method, but assume there is an easier way.
var elem as new Array();
elem[0] = 1;
elem[1] = 2;
elem[2] = 3;
and so on......
Is there a short cut to simply adding the numbers 0 -20 to an array, and is there a shotcut to adding the 20 nuumbers minus a few such as 3, 9, and 17?
