i want required validation when the second ddl is visible only..if not visible the no validation should be done.

View 3 RepliesI am creating dropdown controls in code behind. in some conditions I need to add validation control to dropdowlist. But Validation not firing when I submit button.
If mQuestion.RequiredToAnswer = True Then
Dim mValidator As New RequiredFieldValidator
mValidator.ControlToValidate = mDDL.ID
mValidator.InitialValue = mDDL.Items(0).Text
mValidator.Display = ValidatorDisplay.Dynamic
mValidator.ErrorMessage = "* Required!"
mTableCell.Controls.Add(mValidator)
End If
I have other dropdown controls on aspx page with validation comtrols. Those are working fine. Only when I ddl and validations from code not working?
I have the following markup. The errorPanel was first only used to show server side exception messages, and works fine like that. Now I'd like to incorporate my validation summary into that same errorPanel.
[code]....
My problem now is that the required validation happens client side, and I want to keep that, so I have no server side opportunity to make errorPanel visible, in order to make the validation summary visible.
I see I have two options: Do validation server side, and use my code there to make the panel visible, or hook into the client side code somehow and catch an event there when the summary should be made visible, and then also make the errorPanel visible. How could I go about the latter?

View 1 RepliesI had a web page with 3 texboxes, i need to enter text one of any three textboxes.
for this i need to put required validator.
I'm trying to use a field validator to make sure one of my list boxes has a selection before the user is able to proceed to the next page. i'm having is that if the validation message is triggered, all of the buttons on my page loose functionality.Meaning, if I purposely trigger the validation control, I can't get rid of the error message and none of my buttons do anything when clicke after this.

I have three asp checkbox controls and button click. If any of those three checkboxes is not selected it shoudld validate . How can i accomplish this?
I have found a very useful validation expression at http://regexlib.com/DisplayPatterns.aspx?cattabindex=2&categoryId=3 However, I want to make a couple of changes but am struggling a little!!
The expression is:
^[-]?([1-9]{1}[0-9]{0,}(.[0-9]{0,2})?|0(.[0-9]{0,2})?|.[0-9]{1,2})$
As per the link, this "regular expression will match on a real / decimal / floating point / numeric string with no more than 2 digits past the decimal. The negative sign (-) is allowed. No leading zeroes or commas. It is based on a currency regular expression
by Tom Persing."
I would like to modify this as follows:
- Not match on numbers above 999
- Allow up to 5 digits past the decimal
I'm trying to use required validation controls on two text boxes and tried using the following code:
[Code]....
but I can still enter whatever I want into the text box. What I'm trying to check for is that users are entering a time in a valid format.
I have a web forms where i have 10 required field validators for 10 textboxes. Validation group for these required field validator needs to be determined when the page loads. I tried to change the validator in the .cs file but failed.
rfvBT.ValidationGroup = "registration";
I have a text box and some validation on it. I want to make a panel visible only when
it is successfully validated,i.e.,textbox entry is valid.Also,I want to capture the entered valid value(it should be integer within 1-8) in a session,based on this number,I am going to add that many rows in an editable grid view.
i am working on web-form for which I have set the validation summary showmessagebox = "true".
I have two required field validators, which trigger on a checkbox's OnCheckedChanged event....now my problem is, when I hit submit, the page does not submit if I do not enter any values in the text boxes..which is correct behavior but it does not point out to the error or does not display the message box.
i have to scroll up to see what is wrong with he page and then try to enter the values...I do not understand why my message box does not show up or at least why my setfocusonerror which is set to true does
not show me the text boxes...
find my code below...

i am using the required field validation and Reqularexpressioncontrol in gridview. Fields are in the gridview are in template, but only the edit button it is not templeted, this edit buton is of type Imagebutton and same goes with canel and update.
1_ Do i have to use the Templeted fields for edit/cancel/ and update as well in order to use the validation?
2_Validaiotn should only work when user clicks on the Update button, it should not trigger when cancel button fired.
to explain my problem as simple as i can i have made the following page each textbox is a required field. when i enter valid data in the text box and click the button everything is fine. the problem i am having is that after this button click > i empty out the last 2 textboxes > click the button > the required field validation is not thrown.
the autopostback property being set to true is a must in this case.

I did the data access tutorials on this site.They used validation controls for the insert and the edit template fields. Each of these used their own validation summary control. The markup for them is below. Can I use the same validation summary control for both the insert and the edit validation controls? It seems redundant if i can set the Validation Group property to the same value then I would only need to use one validation summary.I don't know if this is allowed, or a good idea though.
[Code...]
I created some required field validators and a validation summary control. When I get an error it displays next to the control its validating and also inside the validation summary control. I only want the error to display in one place; inside the validation summary control. I tried making the required field validator invisible but then it didn't display anywhere.How can I get the errors to only display in the validation summary control? There is no need to display them twice it just clutters up the page.
View 3 RepliesWe're trying to get a conditional attribute to work, case in point, there's a boolean (checkbox) that if checked, its related text is required. So, ideally we'd have something like ...
public bool Provision { get; set; }
[ConditionalRequirement(IsNeededWhenTrue = Provision)]
public string ProvisionText { get; set; }
Is this even possible?
Alternate idea (not as elegant?)
public bool Provision2 { get; set; }
[PropertyRequired(RequiredBooleanPropertyName = "Provision2")]
public string Provision2Text { get; set; }
I'd hate to use the magic string method .
Search thru the wauy to do view input validation, have seen quite often refers this [Required], eg:
public class ProductViewModel {
[Price(MinPrice = 1.99)]
public double Price { get; set; }
[Required]
public string Title { get; set; }
}
What this [Required] actually is? In which assembly?
I have Dropdownlist whose value field and text field are bind at runtime. it has --select-- as first item with a value of '0' and the rest of the values are bind at runtime.
I have given validaton group for both the control and the validator as "g1" and Intialvalue=0
But still the page is posting back even if I select '--select--' option.

If I have a search object with a list of fields, can I, using the System.ComponentModel.DataAnnotations namespace, set it up to validate that at least one of the fields in the search is not null or empty? i.e All the fields are optional but at least one should always be entered.
View 2 RepliesI am using EF4 and ASP.NET MVC 2 for my web application. I am also using data annotations for my validation.
Is the following possible? If so, how would I implement it? I have a checkbox, and a from and to date. The from and to date are not required fields, but when the checkbox is ticked then the from and to dates are required fields. Then the required error must display.
I have added a Ajax tab control into my page and first tab includes the data entry part to a table and second tab is update the data in a table (Database).

So I understood that the validation controls are worked but it doesn't show the error message. Is there any solution?
