Web Forms :: Validation - Accept Only Integers And Decimals?
Mar 25, 2010
I have A textbox inside formview, ive add litered textbox from ajax and allow only numbers and "."Works fine. THe only problem they can enter multiple dots. I want textbox to accept only following formats: 100, 1234.56 - i.e integers and decimals.
i am using a search box for my application which returns a dataset. however when i click on the search button it returns an empty table result. how could i add validation so it doesnt accept empty strings or numbers.
I'm using MVC 3 RTM, client side validation has been disabled.I have a simple model with one integer field.Server side validation does not accept numbers including one or more thousandseparators.
It shows: "The value '1,000' is not valid for QuantityInStock".It does not matter what culture I use. Both "1.000" and "1,000" are never accepted.
I'm currently stuck with a problem with MVC2 RC and validation on a dropdownlist :
I have a page with some fields and a dropdownlist. The dropdownlist is not a mandatory field so I would like to save a null value into my property.
Unfortunately, I can't validate my page with a null selected value, because when I look into the modelstate just on the first line of my action, I've already an error telling me I must choose an item.
Is it normal working of dropdownlist validation or is it a bug ?
I am working on a website. I am using C# 2008. I want to make a text box that accept only numbers & comma(,). for example-919981424199,78848817711,47171111747 or there may be a single number like 919981424199.
I was able to do one thing My text box only containing number by using this Regular Expression validation.in its property->Validation Expression i wrote "[0-9]+". This is working but now my requirement is to send bulk SMS & each number is separated by (,).
I would like a function/ script to sum the total inputs as an integer or if that's the correct term for it. So it would calculate something like thisJob
PerReview1 = 3 summed as 1JobPerReview2 = 0 summed as noneJobPerReview3 = 5 summed as 1JobPerReview4 = 9 summed as 1
I would also like a total box labeled "NOF (number of factors)to calculate the selections such as;
NOF = 3
This is starting to be mind bugling function
getItems(){var items = new Array();var itemCount = document.getElementsByClassName("items"); var total = 0;var id= '';for(var i = 0; i < itemCount.length; i++){id = "p"+(i+1);total = total + parseInt(document.getElementById(id).value); } document.getElementById('tot').value = total;return total; } getItems(); function getItems() { var items = new Array();
What is the easiest method to enter decimal values into a database using a web control? I would like the details view tool if possible...but whenever I try to upload a decimal I get the error:
Input string was not in a correct format.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.FormatException: Input string was not in a correct format.
I am having an amount filed in my grid and i would like to display the amount field rounded with two decimals value. Like if i enter quantity as 2 and my rate as 300 i would like to display my sum as 600.00 in the cell.
How do I limit my result in my Gridview to 1 decimal places and insert kWh after each answer. For example my current result is 15.513 Im looking to have it display 15.5 kWh. Is this posisble I know for standard stuff like currency symbols you can use
I thought about using LINQ to join the list, but the number of Arraylist can change. I know I can always loop through everything and check if an integer exsist and keep track of it, but I thought there might be an easier way?
I changed a text field to a template field assigning the selected text and the selected value is being assigned to another currency field also templated. I get aa error
[FormatException: Input string was not in a correct format.]
I'm trying to import csv file that that uses double qoutes from the text qualifer but doesn't use any qualifiers for the numbers or null fields. The data looks like this:
I keep getting "Bulk load data conversion error (type mismatch or invalid character for the specified codepage)" when it tries to insert null from the csv into a numeric data type.
I tried changing the codepage, datafiletype, fieldterminator, formatfile but I still can't get it to work.
I have an AJAX NumericUpDown Control that takes a decimal. If I put in 1.30, it removes the zero. I do not want to remove the zero, it must remain at 1.30.
A demo of this can be found here: [URL]
For example, enter 1.30 in the text box then tab out or click somewhere else. The zero is removed.
Is there an easy way to present time (hh:mm) as a decimal value? Example, 01:08 should become 1,13.I have an asp:textbox masked (ajax) as time with the mask format "99:99". Next to this box I need to present the entered value as decimal.
Been Googling about this for a couple of hours but haven't hit on the solution yet. This is an ASP.NET 3.5 app connecting to an MS SQL 2008 backend. The app uses a strongly typed dataset with ad hoc queries in table adapters. The object data source on the markup page will have one parameter that will accept a string of comma separated IDs. I need to feed that list of IDs to the WHERE clause in a query to pull each of the specified records. This is trimmed down version of the query:
I am sorting the grid using DataView's "Sort" property. I am passing sort expression and the order in which the grid is to be sorted(ASC or DESC). But the problem is, since the column on which I am sorting the grid is listing the intergers, the sorting is happening as if it is a string. But I need integer sorting rather string sorting on that column.
The grid displays below as ascending order(string sorting) 55 77 8
But I need the columns to be displayed like this(Integer sorting) 8 55 77
I would like to use the IEnumerable function Intersect() to combine a few list and get the similar integers from each list. The problem I'm faced with is that I don't know how many list I will need to compare.
Here is an example:
A{1,2,3,4} B{1,2,3} C{1,2}
results = A.Intersect(B).Intersect(C)
This works great, but the next time around I may have a D{1,2} next time I come across the function.
I'd like to use the Intersect method, but I'm open to new ideas as well.
