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:

<asp:CustomValidator ID="vldAnswerValid" runat="server" ControlToValidate="txtAnswer" Display="Dynamic" SetFocusOnError="true" ValidationGroup="answer" OnServerValidate="vldAnswerValid_ServerValidate" Enabled='<%# !IsReadOnly %>' />

Setting the function from the codebehind with: vldAnswerValid.ClientValidationFunction = " function(oSrc, args){ alert(1); args.IsValid = false; } ";

But there's no message displayed and no alert. Am I missing something?

Range Validator - Alphabet Entered When Integer Range Checked

Sep 23, 2010

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?

<asp:RangeValidator ID="RangeValidator1" runat="server" ControlToValidate="txtYear"
ValidationGroup="report" ErrorMessage="EM1|Year" MaximumValue="2079" MinimumValue="1900"
SetFocusOnError="True" Display="Dynamic" Type="Integer">

</asp:RangeValidator>

C# - Validate On Multiple Errors With One CustomValidator?

Feb 22, 2010

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?

Web Forms :: CustomValidator Doesn't Validate Dropdowns Correctly?

Dec 20, 2010

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?

Web Forms :: Validate A Maximum Integer Value?

Oct 25, 2010

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)?

For example 0 =< x < 2,147,483,648

Textbox - Validate Text Box Contains Integer Greater Than Equal To Zero?

Mar 29, 2010

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)?

JQuery Validate Formatting Rules For Range Limits

Jan 25, 2011

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:

<input type="text" producttype="CCC" code="ESTFEE" range="460, 500" class="currency required" id="txtEstFeeCCC" value="460.00" name="txtEstFeeCCC">

I've also tried the following:

<input type="text" producttype="CCC" code="ESTFEE" range="[460, 500]" class="currency required" id="txtEstFeeCCC" value="460.00" name="txtEstFeeCCC">

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:

$("#btnSave").click(function() {
validator.form();
...
});

How should an input attribute for jQuery Validate range be formatted so that the correct number range limit is displayed?
