I know the built-in ASP.Net validators come with a client-side framework, however I've been unable to find anything that lets me check a single validator for it's Valid state.
The validator in question is a RegularExpressionValidator, which I use to determine whether an e-mail address is valid or not.
Here's some brief code:

I have a required validator that I check a textbox clientside, but then on post I check the database for values that have been used. I want to show the error in the RequiredFieldValidator when it post back. How do I do this?
View 1 RepliesI am using a custom validator to call a javascript function for validation. My problem is that I need to be able to change the error message dynamically. Here is the code:
<asp:CustomValidator ID="CustomValidator1" runat="server" ClientValidationFunction="fcnValid1"
ErrorMessage="" Display="None" ValidateEmptyText="True">
</asp:CustomValidator>
[code]....
note that the scenario is ASP.NET Webforms + Master - Content page which mess up the ids.
I have, say, three checkboxes
<asp:CheckBox ID="chkConsultantQuality" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantEnvironment" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantSafety" runat="server"
CssClass="company"/>
I would like to make a div id="CompanyPanel" on click event of each checkbox according to the following condition
visible if any of the checkboxes are checked.
hidden if all of the checkboxes are unchecked.
I am planning to use jQuery since I am selecting by class name. I could do it with jQuery.each on the class='company' by checking each for a checked flag.
How can I get ClientSide(JavaScript) Value for My ASP.net Custom Control?
for example I want to get a value like this:
var selectedItemID = getElementById("<%=MyControl1.ClientId%>").value;
How can i set a specific Value in my control scripts to get it from ".value" property like above?
Additional Note:
i want ".value" property(javascript) to get the dropDown control(one of my controls in my custom control) selected Value.
Let's say I have a function that takes a string. That string contains the fully name of an enum type (e.g. "MyCompany.Area.AotherNamespace.MyEnum").
How could I create an array of strings (or List<string>) whose elements are the values of MyCompany.Area.AotherNamespace.MyEnum?
Is that even possible?I'm basically trying to serialize an enum type serverside and then output it in clientside JavaScript so I don't have to define an enum in two places--in my C# and my JavaScript.

View 1 RepliesWhy am I getting this error? I'm trying to do a calculation on my GridView2 and I'm using clientside javascript. I need to add the onkeyup attribute. How do I do this?
Code Behind:

CType(GridView2.FindControl("TextBox13"), TextBox).Attributes.Add("onkeyup", "calculateSubTotal")
End Sub
Im trying to highlight a different element based on the result of a validator.
My form looks like this in structure:
LABEL TEXTBOX VALIDATION CONTROL
When the validation control becomes invalid, I also want the label to change colour.
There are examples of code on the MS website - here is a javascript sample:
[Code]....
isValid always defaults to false and therefore always displays red.
I'm making a website in ASP.NET 4.0 where I make use of the RequiredFieldValidator control to validate a wizardstep.It works perfectly with Javascript enabled, but when I turn it off (in my Firefox) it just goes to the next step.We don't do a Page.IsValid check, but we don't do much on the "next button clicked" event either.Certainly not something that is forcing it to go to the next step.

View 3 RepliesI want to be able to get specific website thumbnails and display them in an ImageBox. The easiest I've found is using a web service. Unforntuantely, most of these services don't allow me to just attach a URL. If I could, then I would just assign the URL of the ImageBox as the URL.
Instead, they force me to use JavaScript like this:
Javascript Code:
<script type="text/javascript" src="http://webshot.in/thumbshot/getshot.php?url=http://www.shrunktheweb.com"></script>
I can do that, but how I would I get the results and assign it to the ImageBox's property?
I'm still learning MVC. I would like to be able to display a list of items in a dropdownlist and then when I select one of those items invoke a new action that will process the selected item.
I can create the DropDownList but I cannot figure out how to return the selected item back to the controller. Below are some snippets from my code. The first shows the Index Action which just gets a list of pathnames which I call widgets. The second is an action which I'd like to use to process the selected file.
The third section is the view in the Index.aspx for the HomeController's Index View.
I have read several articles that show how to do this using JQuery or Ajax, but I'd like to do it without using either so that I can run this on a mobile browser that has no javascript.
I have a GridView in a div wrapper, there is some row headers along the left side that need to be always visible. This all works so far, but I need the wrapper to have a variable width to fit the browser size.
I got the desired width of the wrapper based on the browser width using some javascript but I can't figure out how to set this width as the wrapper.width.It doesn't have to update the wrapper width after the page loads or check for browser resizing.
my poor attempt at diagramming:
| |column headers |
| R |--------------|
| O | gridview data |
| W | |
| | this part |
| H | will scroll |<--->
| E | while the |
| A | Row headers |
| D | stay there |
| E | |
| R |______________ |
| S | scroll bar |
asp:(see edit below)
<pseudocode>
<table>
<tr><td>row headers</td> [code]...
I either need a way to set the wrapper.width = Width or a completely different and hopefully better way to achieve this.
I tried using a % for the width but it doesn't use the browser window as 100%, it takes the % of the full width of the whole GridView
which does nothing for me.
Edit: added some code
<script type="text/javascript">
var Width = window.innerWidth - 275 || document.body.clientWidth - 275;
var divElement = document.getElementById("wrappist");[code]....
I want to disable a ASP.NET RequiredFieldValidator with JavaScript. Actually I'm using the following code:
function doSomething()
{
var myVal = document.getElementById('myValidatorClientID');
ValidatorEnable(myVal, false);
}
This disables the validator. But my problem is, that I'm using a ValidationSummary. And this summary shows the validation message, even if I disable the validator.
how to disable the validator in the ValidationSummary too?
I wanted to write a regular expression using the ASP.Net RegExp validator that would ensure a field contains only numeric and decimal values, and at least one character.
^[0-9]{1,40}(.[0-9]{1,2})?$
Essentially: [0-9]{1,40} - meaning at least one to 40 numeric characters.The ASP.Net regexp validator does not fire for an empty field - where there is not at least one character.
