Web Forms :: Using RequiredField Validator For RadiButtonList In DataList Control
Sep 8, 2012
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" />
[code]...

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:

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 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?

how do I use the datalist "DL_Pro_Result" to find the child datalist "DL_Gro_Result" in C#?
For example in the following code, dlii value is null, even though dli != null.
DataList dli = (DataList)Page.FindControl("DL_Pro_Result");
DataList dlii = (DataList)dli.FindControl("DL_Gro_Result");
<div id="ProList">

When it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?

I'm creating a session variable in my .vb file and I'm able to display it in my .aspx but I can't seem to use it as a control in my asp:CompareValidator. The only way I can think to reference it on the .aspx page is with <%=Session("MyVariable") %> but
such constructs are not allowed in a validator with runat="server". But it seems like the validator must have that attribute and value.
Really what I'm trying to do is validate a user-entered number in a textbox against the one populated in that same textbox from the database. If the user replaces the textbox value with a smaller one I want to show an error message and prevent submit.
