Web Forms :: Can RangeValidator Be Used With Alphabetic Characters
Apr 12, 2010
I want to be sure a user only enters alphabetic characters for a field that accepts strings. They should only be able to enter a-z, no numbers. Can the minimum and maximum values be set to a and z, respectively?
I have a requirment to filter out all users in the database by starting letter. so we will be having link buttons for A B C D E..... Z. If user clicks on A, all users whose name starts with A is retrieved Now the concern is, if there are users whose name starts with any special chars how they can be classified under any filters OR just copy pasting what the client asked me. In terms of filtering UTF characters, is there no way to set it up so that all 'A' (i.e. Ä, Á etc.) characters are assigned to A (i.e. some way of grouping together in an "if else" kind of rule)?
I have the below rangeValidator. However I would also like it to accept 999999,00 (seperated by a comma) I have found the following reg expression: ((d{1,2},)?(d{3},)*(d{3}))|(d+) but I'm not sure where to include this?
I am using RangeValidator whose Minimum and Maximum vales are set in code behind dynamically. Minimum and Maximum values are exracted form the database. These values are in the range of 0 to n (integers only). Therefore user can enter values from0 to n (integers only).Now I have a situation where user can also put -1 which can't be handled by range validator. So my last option is to regular expression to handle such situation.Valid values for the user are (-1, 0-n). But I don't now how to get such regular expression , any help would be appreciated. I can manipulate expression in code behind based on values extracted from the database.Also , maximum possible value for n is 255 (Note: minimum and maximum values are extracted from the database)
I have a text box, a range validator, and a button. The validator is hooked up and prevents the button from doing a post back if the text is out of the range, however I'd also like to enable and disable the button. Is this possible to do within client-side code?
<asp:RangeValidator ID="RangeValidator1" runat="server" MaximumValue=" " MinimumValue=" " Type="Double" Text="Value out of range" ErrorMessage="Value out of range" ControlToValidate="WaterLvl" ForeColor="Red"></asp:RangeValidator>
I want to use a RangeValidator Control which will validate my Password field where i want to check that if user enters less than 6 characters passwrod then it will prompt an error .
I want to give minimum & maximun password size ie minimum 6 characters. It could be alphanumeric & combination of special characters.
Maximum size should be 15 characterss.Same any combination o Alpha numeric or special charactors.
I have done it through Custom Validator .But how can i do this with Range Validator control.
Is there a way to bind MinimumValue or MaximumValue of RangeValidator in it's own ErrorMessage declaratively (in .aspx file)?
I want to do something like
<asp:RangeValidator id="validator1" runat="server".... ErrorMessage="Please enter a value between <%# validator1.MinimumValue %> and <%# validator1.MaximumValue %> />
I would then set validator1.MinimumValue or validator1.MaximumValue in PageLoad, because I get those values from a database.
The following RangeValidator gives me the exception shown further below.
<asp:RangeValidator ID="RangeValidator1" runat="server" ControlToValidate="EstCostTextBox" ErrorMessage="Please enter an estimated cost with only numbers." Text="*" Type="Currency" MinimumValue="0" MaximumValue="9999999999999999999999999999999999999999999999999999999999999999"><img src="images/icons/WarningHS.png" alt="Warning" /></asp:RangeValidator>
Exception information:
Exception type: System.Web.HttpException
Exception message: The value '99999999999999999999999999999999999999999999999999999999999999999' of the MaximumValue property of 'RangeValidator1' cannot be converted to type 'Currency'.
I have a DetialsView that has a year field that needs to have the range set dynamiclly
I use this when it was just a textbox outisde the detailsview
protected void Page_Load(object sender, EventArgs e) { rvYear.MaximumValue = Convert.ToString(DateTime.Today.Year); rvYear.ErrorMessage = "Must enter a year between 1900 and " + Convert.ToString(DateTime.Today.Year); }
I have a form where one field needs to check if the person is up to 17 years of age by between 01/01/2011 and 12/31/2011.
So I added a a Range Validator and Validator Callout Extender
How can I get the page to check this range when the user enters in their dob in the dob textbox then when they go and enter a date in the bmidte box (if they are over 17 years of age) I want my error message to apper.
Here's the aspx page code:
RangeValidatorBMIDte.MinimumValue = "01/01/2011" RangeValidatorBMIDte.MaximumValue = "12/31/2011" RangeValidatorBMIDte.ErrorMessage = "Date Entered is NOT Valid. Value needs to be between 01/01/2011 and 12/31/2011." 12/31.
I need to validate integer within a specified range for English and French culture. The integer contains group separator ("," in English culture or " " in French culture). It seems I can't do it with RangeValidator on my machine.
I just want to make sure the RangeValidator can't do this kind validation for Integer before I'm going to write my own control.
I just feel curious because RangeValidator can actually do this kind of validation for Currency!
I have a string with 100 characters and it is for me too long in one line. I want to make NewLine after each 25 characters. For example:
Instead: "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua."
I have a application that takes a tab delimited text file parses and the inserts the data. Some of the data has international characters. My problem is it appears that my application is changing the characters. For Example the file might contain something lke this Andrlová and is converting it to this Andrlov�
I am passing this into a sproc. The datatypes for my paramater & DB Field is nVarChar(50). If I insert the data directly into my table or if I call my sproc from a query window and pass in some data it works fine, but when my app touches the data it appears to get messed with.
I am working on a ASP.NET app that supports user level cultures. Just about everything works, however, I am running into a problem with the RangeValidator. Here is the sample control set:
[Code]....
When a culture that uses "0,0" (pt-BR for example) attempts to load this page with the controls as shown, it bombs (Gives an ASP.NET debug page). If I either set MinimumValue="0" or add CultureInvariantValues="true" the page will load. The problem with this is that on several controls, the minimum value is actually 0.0001. When I use the CultureInvariant setting, that validator is telling me that the following values are invalid: ".031" and "1", no matter what culture I am using to view the page.
I understand the the CultureInvariantValues setting applies only to the values in the Min/Max settings on the validator, not on the data entered in the control that is being validated. But this does not explain why values that should be accepted as valid are being flagged as invalid.Our application currently runs in 20 different countries and is internally translated into 4 languages (based on user culture settings), with 3 more on the board for this year. I have googled this extensively, and while I have found some info on Currency and Date data types, the problems experienced are not the same.
I have Asp:TextBox,Asp:RegularExpressionValidator and Asp:RangeValidator on .aspx page.
These two validators have ControlToValidate value equal to textBox Id.
RegularExpressionValidator have validation Expression such that it allows only number.
Range validator have maximum value ="100" and if I enter any text then both validators get fired .
Logically only RegularExpressionValidator should fire if I enter any textvalue.
Is there any property of Range validator such that it check for numeric value to compare and disbled if value entered in textBox is some text so that no handling of event(Client side and Server side both) is required.
