Javascript - Validate An Integer Range With A CustomValidator
Jan 22, 2011
I'm trying to validate an integer range with a CustomValidator. The range is set dynamically, so when either the min/max values on my usercontrol change, the client validation function is updated. However, I can't get the validation function to fire. I have this code:
I have a Range Validator as follows. It is for restricting values between 1900 and 2070. However, it fires error when I enter a alphabet also. I want this to be fired only if the user enters integer values. How do I overcome it?
I am trying to figure out how to use Validation on Business Objects. Until now I have only seen examples on CustomValidator that checks for only 1 error. I have two fields with DateTime input that should check for 3 or more errors. I guess normally I should check on client, then on server, last on database level. If I get an error on a field, I should not be able to leave the field. On the Client Validation this is not an error that should cause an Exception since its only a user error. But if something goes wrong and the user bypass the Client Validation, the Server Validation should kick an Exception. And last, if i have other e.g. Batch Update work then they should use the Database Validation code.
`dateFrom` is not empty. (But `dateTo`can be empty) `dateFrom` is earlier than `dateTo` `dateFrom` and `dateTo` is within constant `MinDate` and `MaxDate`
So How should my Validation look like, Client, Server and Database?
Thoughts: Should the validation logic be separated on 3 different places; UI, Code and DataObject(Database)? When it is the exact same code? Seems redundant? Can I use the same validation method for all three checks? Or do I need to implement 3 code-chunks, and 3 Methods for each, and then how do I list all in the ValidationSummary nicely?
I have two lines of dropdown menus. There are 3 dropdown in each line (together 6). First dropdown in each line is "independent". The second and third are dependent. If user selects second, page loads and user can then selects item in third. So user have option to select first OR second and third in each line.
.ASPX code:
[Code]....
Since I've found out that you can't validate dropdown controls directly with CustomValidator I've wrote few lines of code for each of dropdowns to insert some values in txtBx_Cln1n2 which will be hidden when the page will be finished.
[Code]....
Unfortunately the code for CustomValidator have some bugs. If user doesn't select anything error message is shown. But if he choose 1 employee and then second and then select (I doubt that anybody will do this but I want to be sure and prevent as much exceptions as possible) the first item in one of the dropdowns ("all employees" or "employees by group") the custom Validator will allow execution of code for link button although the validation code should prevent this.
[Code]....
I know I could this a little better since code is quite complicated if I want to tell the user which employee he/she forget to enter. I've tried instead of SelectedItem.Value also SelectedIndex != 0 but the problems are the same.
I couldn't validate this without the use of textbox. But this method is also making complications since user can select 2 employees and then in one of the selected dropdown change selection to index = 0. Maybe I have to disable viewstate on all dropdowns? But this would probably affect INSERT of data?
A very easy one hopefully - what expression can I use to validate an integer to ensure it is greater or equal to zero, but less than 2,147,483,647 (i.e. the maximum value of an integer)?
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)?
I have a large table of text inputs for which a set of custom attributes are being created on the server side. These attributes included "min" and "max" which were used with the jQuery Validate plugin. Due to a change in the requirements (of course), we now have to update the attributes to a range type, however the Validate plugin isn't interpreting the formatting of the range rule correctly (or perhaps it's more accurate to say I'm not formatting the rule correctly) and now I have problems. The generated output for the input boxes looks like this:
In either case, the message returned is either: enter a value between 4 and 6. or enter a value between NaN and 4 respectively. Neither of which has anything to do with the 460 - 500 range in question. The jQuery code calling the validate function is just the vanilla call:
I've set up a CustomValidator with a ClientValidationFunction as:
<asp:CustomValidator ID="CustomValidator1" runat="server" Display="Dynamic" EnableClientScript="true" ClientValidationFunction="checkClients" ErrorMessage="You must select at least one client or staff" SetFocusOnError="true"></asp:CustomValidator> <script type="text/javascript"> function checkClients(sender, args) { [code]...
I have the following setup, where I am custom validating a textbox. It works fine as long as I am manually typing in the textbox and changing the text and focusing out of the textbox.
[Code]....
when I try to invoke validation change event from javascript (using JQuery 1.4.2)
I am building a CustomValidator, here is my html declaration:
[Code]....
I can not figure out how to get client side javascript to change the error message of the CustomValidator, unlike server side I can change ErrorMessage property. Here is the client side javascript declaration:
has anyone implemented date range vaildation using jquery.validate file? when i m trying to implement it with mvc application its not working properly , as its working only for numeric types. wl range validator of jquery validate only numeric values ?
I need to filter data based on a date range. My table has a field Process date. I need to filter the records and display those in the range FromDate to ToDate.
When using a range validator, if the user exceeds the defined range, How do you code it so it disables a button so the user can't continue. (without using JavaScript)
I have a table "RANGES" with the following columns
LowRange as int HighRange as int with the data similar to below select * from Ranges LowRange HighRange 1 100 101 200 201 300 . . . 901 1000
And another table "infoDetails" with the following columns
Range as INT amount as money with the data similar to below select * from infoDetails Range Amount 23 34.00 235 44.00 345 34.00 678 100.00 555 100.00 530 100.00 510 100.00 I need one report with the following format without cursor. LowRange HighRange Count Amount 1 100 1 34.00 101 200 0 0.00 . . 501 600 3 300.00 601 700 1 100.00
