Im using regular asp.net c# (webforms)
i need to build a simple form that has some simple validation. i need to ensure that the form works correctly even if javascripts is disabled. will Page.IsValid be sufficient for this, or is there anything else i may have to consider?
Dispite what the topic subject says, I really want the opposite. I panel with a form and validations that's hidden. I also have another form that I'm trying to use on the same page, but the page won't validate because of that hidden form. Is there any way around this? Can you tell the brower NOT to validate just those hidden fields?
View 5 RepliesI have a submit button on my form. However, I would like to do validation before submitting.
View 9 RepliesAfter 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?
View 4 RepliesI'm working on a very dynamic site build at the moment. What I'm trying to do is creating something like a survey that can be created dynamically from a control panel. In the control panel you add input fields (these are saved in a database), what the user then see is a form that I generate from the database. So if I add 3 input fields to the database the survey will contain 3 fields. If I add 20 fields the survey will have 20 fields.
Now my problem is that I want to validate these fields, and I would like to be able to hook me in with the standard validation flow. I can't create a Model with validation rules since the number of fields and their names are dynamic the only thing I know is what kind of data that is expected in every field (this rule is found in the database). In an ordinary case I would get the automatic highlighted fields that are not valid and so on thanks to the built in validation flow with ValidationResult and so on.
So the question now is can I somehow simulate parts of the validation and then hook me back in with the validation result, and if not valid, the form prints the error messages and fill the fields with the data that was given?

Possible to use a link control to validate and submit a form? What would be the code to tie the click event of the link control to the submission functions? (I prefer link buttons much more than input buttons for styling across browsers.)
View 1 RepliesI am beginner to MVC. I have created a View with dropdownlist, text box and text area. I didn't create a strongly typed view because these fields are not generating from the database. Is this right way of doing it? Do I have to create a 'Model' class and generate a strongly typed view? I am trying to validate(client and server side) these fieds before saving into the database. How to create a Model class for these fields?
Here is my view looks like.

I have a web form where I create an array of type structure.
In this form I have:
[code]....
but this is not OK.
I have a web form where I define an array of type struct and I redirected it in the <script runat="server">
section of the second web form. But when I use that array below, in the <script type="text/javascript">
section in the html code of the same web form an error occured in the for cycle saying that the array (Array1) is undefined, and also the counter which I also defined in <script runat="server"> section.
I have this code in the <script runat="server">
section of the second web form:
public struct Point1
{
public float lat;
public float long1;
}
protected void Page_Load(object sender, EventArgs e)
{
//Retreive from session
Point1[] Array1 = Session["s1"] as Point1[];
//Run a Foreach loop
int nCnt
= 0;
foreach (Point1 p1
in Array1)
{
float x1
= p1.lat;
float y1
= p1.long1;
nCnt++;
}
}
and in the <script
type="text/javascript">
section I have:
var
for (var i = 0; i <
nCnt; i++)
{
lineString.getCoordinates().pushLatLngAlt(Array1[i][0], Array1[i][1],0);
}
lineString = ge.createLineString('');
lineStringPlacemark.setGeometry(lineString);
I have a form that contains several textboxes and each one paired with a required validator. Each box reads a value from a dataset, and on submit click, update the database with the new value. For some reason, one of the validator always returns the error message even if I enter a value in the textbox. My code is something like this.

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?
