How to validate the textboxes to avoid wrong information..for ex: I have a textbox phoneNum in that users can only enter the nums only. how to validate that?
I'd like to generate an OId number in a specific textbox on a specific page which comes out of date and time, for example if today is may 27th 2010, 9:45 am,it will generate the number 270520100930
it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)
If I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator?
Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?
So, how do I, at runtime, add these fields to my page?
Secondly, This form, upon submittal, creates a configuration file on my server currently in the format of
[FIELD1] FieldOne.Value [/FIELD1]
[FIELD2] FieldTwo.Value [/FIELD2]
[FIELD3] FieldThree.Value [/FIELD3]
With those fields, it's rather easy, as the form has static controls that I'm looking up and sending to my file.
How would I add the dynamic controls to the file as well? Obviously, if they've selected to add 10 fields, I don't want 40 other fields of blank/nothing (since they can choose to add up to fifty). How would I iterate only adding the fields that they've chosen?
I have been trying to figure out how to use <asp:requiredfieldvalidator> with ValidationExpression but am having a difficult time understanding the syntax of ValidationExpression. I'd like to make sure one textbox's number (1-12) is equal to or higher than the other textbox's (1-12) number. How is this accomplished and what's the syntax of ValidationExpression (hopefully I'm stating the question correctly).
I am using the asp.net and framework 2.0 with Ajax enable web.i have a text box and when user will enter "a" or number in this will search the name started from "a" character or number if he or she enter the number basically we can say live-search.
Employee search: Textbox.In this text box she/he will enter the first character of name or first number of employeeno and according to the a character name will search in list.

I have a SQL database with a table storing three collums. ClientID, StartRange, EndRange.The user needs to add records to a different table - the number being inputted by the user eeds to fall in the range where it is equal to the client he is adding if for. There can be a number of different ranges for a client which where I am falling over, it would be easier if it was just the one range!What is the best way to check this- I was thinking a customer validator method in the code behind?Would I need a Stored Proceedure? or some DataSet Tables and some how parse the ranges?
I am trying to figure out how to get the text value from each textbox on a page that has a dynamically created number of text boxes. I need to store that value in a database row. I guess what i need is to be able to store the text box values in a collection or arrary of some sort and then be able to use textbox(i).value or something of that nature. Not really sure where to begin.

I have a peculiar situation at hand in which I need to validate a pair of dates in an ASP.Net web app.This is how my page looks like : I have a "From Date" field which consists a set of three dropdownlists ( for Year , Month and Date) I have a "To Date" field which also consists a set of three dropdownlists ( for Year , Month and Date). There is a "Download Report" button on the screen ( which allows a user to download a report for the specified date range) All these six dropdownlists are wrapped in a user control. Now all the 6 dropdownlists have a default "please select" value. When a user lands on the page for the first time , all dropdownlists are set to "please select". The "Download" button is enabled only after valid 'From' and 'To' dates are selected. Now my requirement is that :
When a user lands on the page for the first time , no attempt to validate the dates should be made until he selects all the 6 dropdownlists at least once. When the 6th dropdownlist is selected , the From and To dates should be validated. Once a user has selected all 6 dropdowns once , subsequently on every dropdownlist postback , the dates should be validated. My Issue: What's the best way to track these 6 distinct postbacks ( for each of the dropdowns) before starting to validate the From and To Dates. I could maintain a flagin ViewState .. but is there a better way?
