Web Forms :: Multiple Radio Buttons Are Set As TRUE In Post Back?
May 9, 2010
In my code, I cannot use a radiobuttongroup due to formatting constraints. This is a page where the user can update the data. So I have
<asp:TableCell ID="TableCell1" CssClass="answer" runat="server">
<asp:RadioButton ID="PatientYes" GroupName="Patient" runat="server" />
</asp:TableCell>
<asp:TableCell ID="TableCell2" CssClass="answer" runat="server">
<asp:RadioButton ID="PatientNo" GroupName="Patient" runat="server" />
</asp:TableCell>
If I have the case where one button is set when the page is displayed and the user changes to the other value, BOTH are coming back as TRUE. How can I just get the value selected by the user?

the form has 15 items to choose with radio buttons, any number can be selected. I would like to process them as a 'group' so I can do something like loop thru them, checking if each one has been selected to build a list and also be saving them to a table row, etc but it seems all the designations as a list or group make it mutually exclusive. just looking for better coding than checking them with an if statement or similar so the question is if there is some way to designate the radio buttons as a group but no force the group to be mutually exclusive

I am looping through all the posted data on my website and grabbing the values, this will then be used later on. The user is going to put 2 radio buttons on the page, one with a correct answer and one with an incorrect answer. I need to know how to see if a Radio Button is checked or not based on the posted data.

I have a asp.net app that I want to disable the buttons as soon as they are clicked in order to prevent multiple submissions. I'd like to use jquery for this as the site already liberally uses it anyway.
What I've tried is:

I am using one ReportViewer with already established SQL Stored Procedures connected to three report files (*.rdlc). There are three radio buttons which are to be associated with each report that needs to be displayed in the ReportViewer. Here is an example if a radio button is selected:
[Code]....
The ReportViewer works for the first radio button selection but then for the other selection I get the following error:
A data source instance has not been supplied for the data source 'spEx1'

watch here:
- Create a gridview with AllowPaging and AllowSorting = true
- On page load, I bind it to datasource (in my case a webservice)
- On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting.
- Call sorting method
This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.
I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.

I have a web application that shows a page containing between 6 and 20 AJAX UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here:
[URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button
clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
Not sure if this is an AJAX issue, or general ASP.NET UI issue, so I'm posting in two forums on this one.

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I am using Asp.net and requirement specifies i use html input to post files to server rather than asp:fileupload.[ Reason : Add more html input file controls similar to CPanel file manager.(i.e) clicking on link adds another file input from which user can select another file*.But when ever i post back Request Files collection is always empty.*
HTML FORM:
<form method="post" enctype="multipart/form-data" action="documents.aspx">
<div>
<input type="file" name="attachment" id="attachment" onchange="validate(this)" />
<span class="none">Filename should be within (1-25) letters long. Can Contain only letters
& numbers</span>
<div id="moreUploads">
</div>
<div id="moreUploadsLink" style="display: none;">
<a href="javascript:addFileInput();">Attach another File</a></div>
<input type="submit" id="btnSubmit" />
</div>
</form>
Javascript:
var upload_number = 2;function addFileInput() {
try {
var fileUpload = document.getElementById("attachment");
var elemSpan = nextElement(fileUpload).cloneNode(true);
var elemDiv = document.getElementById("moreUploads");
var d = document.createElement("div");
var file = document.createElement("input");
file.setAttribute("type", "file");
file.setAttribute("id", "attachment" + upload_number);
file.setAttribute("onchange", "validate(this)");
d.appendChild(file);
d.appendChild(elemSpan);
elemDiv.appendChild(d);
upload_number++;
} catch (err) { alert(err);}}
the validate(this) is a function that validates file types on client.When validation succeeds then the link to add more file inputs is enabled. Could someone throw somelight on this.

Using Vb.Net 2003 Asp.Net 1.1
I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.

I need a control which can hold an image and two radio buttons, like the one we have when we upload a pictures on fb / orkut. 1. Image 2. Delete radio button. 3. Cover radio button. [Set this image as cover of album]
i have created a user control with these three things. On my aspx page on click of a button i need to add this user control. Means, user will select the image using FileUpload and when he clicks on the button this user control should be loaded. I am able to load the control. Check the following code.
[Code]....
1> All images come on new line i want them next to each other.
2> How to detect which radio button is clicked as i have more than one images, and all have radio buttons.
3> How to capture click of radio button from aspx page?
4> If there is some other way to achieve this let me know.
Searched on google but could not find a solution for this.

I have a writing a web page that will use several different types of control. The control types will depend on the data being read from a SQL database. The following is my code that decides what control to add to the page:
Select myReader.GetString(1)
Case "DatePicker"
Dim bdpAnswer As BasicFrame.WebControls.BasicDatePicker = New BasicFrame.WebControls.BasicDatePicker()
bdpAnswer.DateFormat = "dd/MM/yyyy"
divAnswerContainer.Controls.Add(bdpAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "DropDownList"
Dim ddlAnswer As DropDownList = New DropDownList()
divAnswerContainer.Controls.Add(ddlAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "RadioButton"
Dim rbAnswer As RadioButton = New RadioButton()
divAnswerContainer.Controls.Add(rbAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "TextBox"
Dim tbAnswer As TextBox = New TextBox()
divAnswerContainer.Controls.Add(tbAnswer)
Answers.Controls.Add(divAnswerContainer)
End Select

I've got 3 groups of controls each of which I want enabled/disabled depending on which radio button the user has clicked.
The code *works*, but daaaaaayuum the postback time from a radiobutton click is long.
I suspect my approach is the noobish way, and that there's a slicker way to achieve this control-groups-enabled effect.

I have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.
When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.
I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.
The pages is

I have a user control I'm building that has a table layout with two sets of radio buttons, like:
how I could use a radiobuttonlist for each set of vertical buttons within this layout, unless I used a rowspan on each col, but that seems problematic from a layout perspective? I would rather use a RBL from a programming standpoint.
If I instead used a set of radiobuttons with a groupname for each, how do I get/set the selected button (for each set) from outside the UC?

I'd like for where there is a 1 for it to display a checked radio button, and where there is a 0 for it to be unchecked. This can then be edited by clicking the radio in another column where necessary.
