Web Forms :: Validate Number Inputed Is Inbetween Ranges Sotred In A SQL Database?
May 26, 2010
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 getting Range1 and Range2 from database. Dataset is like below.
Range1 Range2
AB100 XY200
AB300 XY400
AB500 XY600
I have to bind these ranges to a Drop Down List as list items includung range number in my application.So list item should be like ==> 1 AB100 XY200 . When user selects a range I have to pass Range1 and Range2 to database.
How can I bind the two ranges with range number to Drop Down List.

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 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?
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.)
I remember seeing an example explaining how you could setup the asp.net chart control to show two sets of data from different date ranges on the same chart, but I can't find it now that i need it.It showed sales for Jan, Feb Mar 2009 in one series and sales for Jan, Feb, Mar 2008 in another series and had the chart in 3D so that one series was in front of another.Does anyone know of such an example or have any pointers how to achieve it?
i am working on an availability / booking system, one element in the form will be a dropdownlist control with a selection of date ranges for a customer to select the period they want to book.these will be a list of ranges for each week (monday - sunday)eg
27th Sep - 3rd Oct 2010 4th Oct - 10th Oct 2010 11th Oct - 17th Oct 2010
etc
is there an way to populate this dropdownlist dynamically from a calendar or date function so it can cater for dates up to 18 months ahead?i dont really want to populate it from database entries or hard coded list items if there is a less laborious way.
I have a aspxtextbox and its validated from database.If text exists in database then it shows message Username exist.Now this is all happens on click of a aspxbutton after typing some text into aspxtextbox.I just want that when user defocus the textbox then it will automatically check from database and shows the message if exists.
After submitting a form, i would like to read that it is actually there, before giving my succesfully submitted message. How would i go about checking that in the easiest way?
I'm trying to create a simple user registration page. I'm using an MS Access database which has some test data in it. What I would like to do is use a CustomValidator on the user name textbox to check if the user name entered already exists in the database. I've read about the possibility of using the ServerValidate event for the CustomValidator control but I can't figure out how to make a connection to the database, query it to check the existing user names, and then fire off the CustomValidator if the user name exists.
