Validate Radiobuttonlist In A Gridview Using Javascript?
Feb 10, 2011
I am trying to validate that each radiobuttonlist has been selected. the radiobuttonlist is dynamically created from a sql database. The following line errors out "if (MyRadio[j].checked) {", the error is "checked' is null or not an object". The following is the code.
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" runat="Server">
<cc1:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0" CssClass="ajax__myTab" Width="100%" ScrollBars="Horizontal">
<cc1:TabPanel ID="TabPanel1" runat="server" HeaderText="" Enabled="true">

I have 2 radiobuttonlist in a web forms, each contains of 4 ListItem. So there are 8 ListItems in total. It is initialised such that none of the ListItems is selected. I want to validate that at least one of the ListItems is selected when submit button is pressed. How to do it? i.e. at least 1 ListItem is selected, either from radiobuttonlist1 or radiobuttonlist2.

Can any one let me know "How to validate the length of the text present in the textboxes of a Gridview using javascript".
For Example: In a page I am displaying a Gridview with textboxes inside it and a button on the page. The user need to input some text in the textboxes of the gridview and click on "Submit" button. When the user clicks on Submit Button, we need to validate the length of the text present in the textboxes of the gridview. If the length of the text inside the textbox of the gridview is less than 10 , we need to throw an error message. In the same way we need to do validation for each and every textbox inside the gridview.

I am developing a website using asp.net and C#.I am using a RadioButtonList control. The code snippet for RadioButtonList is shown below
<asp:RadioButtonList ID="RLCompareParameter" runat="server"
RepeatDirection="Horizontal" meta:resourcekey="rsKey_RLCompareParameter"
AutoPostBack="True"[code]...
There is a button in the same page. While clicking on that button i want to display an alert message based on the selected radio list item using javascript. Some part of my javascript function is shown below
var RLCompareParameter = this.document.getElementById("<%= RLCompareParameter.ClientID %>");
if (RLCompareParameter.SelectedValue == "Forms") {
if (document.getElementById("<%= lbAvailableForms.ClientID %>").value == "") {[code]...
But the if(RLCompareParameter.SelectedValue == "some value") always false. i think there is no attribute like selected value for RadioButtonList control.

I'm posting this here because my question isn't really about the javascript itself but about the workings of the RadioButtonList control. I have a webforms application where a several radiobuttonlist controls are rendered dynamically from server side code. I want to also render an undo button that will clear the associated radiobuttonlist. I can get it to work fine using an image button that does a postback. However, I'd like to do it without the postback, waiting until the entire form is filled out before posting back via a submit button. I've been able to get it to clear the radio buttons via javascript. However, when I click submit to post back to the server, the server thinks the radiobutton is still selected. Here's a condensed version of the code thatrenders the controls.
[Code]....
At run time, the radiobuttonlists and their associated undo buttons are rendered just fine. If the user selects an option from a radiobuttonlist and then decides they didn't want to answer that question, they can click the undo button and in the browser the correct radiobuttonlist is cleared. However, when they submit, it still saves whatever value they had clicked before to the database. It's as if there is something else on the page that is holding on to the selected value in the radiobuttonlist even after the javascript clears the control itself.

If we are using ASP.NET Radiobuttonlist in our page it becomes a little difficult to find the instance of it through Javascript because it is rendered in a different way in the browser ( the code is reproduced below )

I'm at my wit's end when it comes to this. JavaScript definitely isn't my strong suit and I've been trying to google for a solution. Here's the code I have:
[Code]....
What I want to do is whenever you click a radio button on the Group1Most RadionButtonList, it will disable the corresponding radio button on the Group1Least RadioButtonList. The problem is I can't figure out how to select an individual radio button within the RadioButtonList.

I have a scenario where a RadioButtonList needs to be in disabled mode by default and then on some event on client side, say, when a checkbox is checked, it needs to be enabled.
But once I disable it from code-behind, the javascript part of enabling it doesn't work.

I have used a radiobuttonlist to enable/disable the textbox in Grid View. I did this using javascript onclick event.
[Code]....
It is working fine when the page get refreshed too.
[Code]....
Then in a scenario, I have removed the radliobuttonlist items (items 2 and 3) dynamically. For the first time when its loaded its working without flaws. After a page is refreshing due to any serverside events, the javascript to enable/disable textbox is not working.
[Code]....
I have verified the HTML file, the radiobuttonlist is loaded without the onclick event.

I've got a simple form with some textboxes. These textboxes all have a RequiredFieldValidator. If field 1 is filled in I need to disable the RequiredFieldValidator of field 2 because only one of these fields is required. What is the best way to accomplish this?

When I use a compare validator, datatypecheck="String", and try to enter the following code to test, the comparevalidation doesn't catch it in time, and instead the browser pops up with an error saying the text is not allowed.
Will JavsScript validation catch it?
