Web Forms :: RequiredField Validator Seems To Be Validating Some Other Control?
Mar 11, 2010
I'm adding RequiredField validators to a group of RadioButtonList controls, and something strange is happening when the page loads. The page renders just fine with no validators tripped, but as soon as I click on one of the radio buttons, the validator for that RadioButtonList fires and shows me the error message. I initially thought that maybe the various validators were cross-linked, so I tried clicking on a radio button in every list, but they all react the same. Here's the code that generates the whole thing:

I got a problem when using required field validator in datalist ,We have 4 polls. In that user must answer two polls which are required.I have added all the four polls in my datalist ,it is displaying fine and while clicking submit button the required field validator is working and giving the error message. Once we answered the required polls and clicking submit button again, all other polls which are not required showing as required one.My poll answer getting submitted thats not a problem ,I want to avoid displaying the error message for non-required polls.Here is my design and code:
<div id="pollQuestion_div" Class="read-messages-poll" runat="server" >
<asp:DataList ID="PollDataList" runat="server" onitemdatabound="PollDataList_ItemDataBound">
<ItemTemplate>
<asp:HiddenField ID="PollIDReqHiddenField" Value='<%# Eval("PollID") %>' runat="server" Visible="false" />

Using javascript or jquery, how can I make a Required Field Validator control (of ASP.NET) visible. If we check the viewsource of the Required Field valiator, we can see that the visibility is false initially. $("#spanReqFieldValidator").show() / fadeIn() wont work.
From googling, I understand that jQuery has some issues with visibility attribute.

I have radiobuttons within a datalist. The page where they appear is within a master page. The method I had in mind of achieving the validation is with a custom validator and the following sub:
[Code]....
The problem with this code is form1 is not declared. As it is passed in from the master page.
I also have tried another method as follows:
[Code]....
With this sub:

I then get the error Microsoft JScript runtime error: Object expected
Here is the datalist. I need to make sure the user selects an answer for each question:

I have created the user control and it has got one table with few rows in it. One row has got a text box with custom validaor and other row will have check boxes dynamically added through server side.
On the main page, i am loading that user control about 10-15 times depending upon the values from the database.
Is there any way of setting the properties of user control validator on the main page? Text box will only be validated if any check box is checked in the user control.
I am also not able to find the usercontrols through the main page.

I have a custom user control with some input fields and a submit button. I need to validate the fields using the jquery validation plugin when the submit button is clicked. (The function of the submit button is to create another custom control which displays the data entered in the above mentioned control)
Bt as far as I knw, validation plugin works only with form validation ryt? And my custom control does not contain a form tag as I am using master pages. The custom control is present in one of the content pages and the master page already contains a form tag with a runat=server attribute. And I guess one page can contain only a single form tag with runat=server attrib ryt?
So how do I get it to work?

I have more than two text boxes in my web form.Now I want to validate either of the text boxes value is empty then only user should get error message i.e enter either text values.
For ex: There are two text boxes Phone no and Name. If user clicks on submit button without entering in either of text boxes then only user will get error message i.e enter either phone no. or your name .I can use the javacript in order to solve this case but I want to know is there any control in asp.net to solve this purpose?

I have a a web form with multiple formviews and one field is a mandatory field. Each formview has its own submit button. User cannot submit the data in any of the formviews until that one mandatory text field is entered.
But I also have another section in the webform, which has a calculation code in it. It takes in input from two text boxes, does some calculations and displays the result in another text box. Because of the validator control, I am not able to run the calculation code without the mandatory field filled in. I would like to run the calculation code irrespective of the mandatory field.
How do I do this? I need that submit button (in calculation section) to disregard the validator and display the result.

I am adding validator controls to a page on runtime. When I do this it seems to work except for one thing: the page doesn't get validated (the Validate() method is not invoked) - neither on the client nor on the server. However when I can Validate() myself, the validators do their work and generate the required errors. So it looks like the simple fact of adding a validator programmatically causes the page validation to not take place. My page does have validators in the aspx file - they work fine when I don't add any programatically, but as soon as I do add one programatically, the Validate() method is not invoked.
The way I add the validators is by creating an instance, giving values to all relevant properties, and then adding to the page control collection. I tried this in the PageLoad, and prior page-cycle events. The same result occured. I also tried with or without having a ValidationGroup, and with or without having a ValidationSummary control on the page. The same result occured.

I have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?
