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.
it was possible to create X number of radio button groups depending on a parameter.
Say if I Selected Fruit as the parameter these groups would need to be created;
APPLE
- Green
- Red
- Pink
GRAPEFRUIT
- Yellow
- Pink
GRAPE
- Green
- Purple
And if I were to pick vegetable;
TOMATO
- Regular
- Cherry
POTATO
- Brown
- White
So when I pick "Fruit" 3 Radio Groups appear(APPLE, GRAPEFRUIT, GRAPE), and when I pick vegetable 2 Radio groups(TOMATO, POTATO). Obviously this sample data is dumbed down, and my Radio options are going to be retrieved from the DB. Can this be achieved?
i have a table which looks something like the following
<table id="Table1" border="0">
<tr>
<td><b>1.</b> Question 1</td>[code]....
how do i go about looping through each group of radio buttons and getting the text of the selected radio button ?the code displayed above is created dynamically ... in my aspx file i have the following code
<asp:Table ID="Table1" runat="server">
</asp:Table>
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.
In my form i have three radio buttons and nine image buttons, three image buttons per radio buttons
If the user check one radio button, the respective three image buttons only has to be displayed.
In a single time one radio button only can be checked the rest two would be unchecked
Here i have pasted the aspx file design source

I have a table, that contains a number of rows, in each row there are three columns that are mutually exclusive. What I need is to be able to have radio buttons that are linked across the three columns.

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.
I have a formview that runs of an SQLDS, very simple stuff. Inside that form i have various fields, one of them is a credit field, one of them is a debit field. Now i have put a radio button list with two radio buttons (credit and debit). What i want to do is when the "credit" radio button is enabled i want the "credit" text box to be enabled and visa versa.
I know how to reference an object inside a formview, but i am confused, do i reference the radio button list and then the list items inside it or?
asp.net using visual studio 2008 3.5 framework with sqlserver 2008. I have a webform (derived from master page) so its a content form with content placeholder. It has two text boxes, dynamically populated checkboxes from database and 8 radio button groups. It has two custom validators attached with two of my fields also. I've tried every way to clear my form but its not working somehow. I've tried Control iteration method. Ive tried btnReset.Attributes.Add("onClick","document.forms[0].reset();return false;"); thingy...but none is working.
View 4 Replies"Radio Buttons Are Not Mutually Exclusive When Used in a Repeater" according to KB #316495 http://support.microsoft.com/kb/316495. This bug also exists with ListViews, and I am having a hard time developing a workaround. Is there a solution or workaround available? I'm using Visual Studio 2010.
(Here is my ASPX. I want rbGroupedSession and rbFees to be mutually exclusive. Databinding and setting controls visible attribute to true/false is done in the code-behind. I'm also setting the RadioButtons "GroupName" property correctly in the code-behind, but it gets changed when rendered in the browser -- which is bug KB #316495)..

I've got a gridview that will allow clients to edit options they've already entered on another page. The gridview has three radio buttons in it each with a value of 1,2,3. The option value in the dataset is 1,2 or 3 respectively. I would like to have the radiobutton with the corresponding value selected in the gridview so they can see what they previously chose and will then be able to edit, if they wish.
Here's my code so far:

How to use radio buttons with example is ther any good article related to this in mvc mobile?
View 1 RepliesWorking on VS2008 with using .vb
I have placed two radiobutton's on simple .aspx page. I didn't used any Update Panel or any javascript on that page also set both radiobutton's AutoPostback="True", But it's not responding as I want.
I have 2 button links and 1 text like this:
Previous JULY Next
Every time i press Previous, a variable mymonth subtracts 1 , and when if i press
Next , the variable mymonth adds 1.
Previous LINK: <%# mymonth - 1 %>
Next LINK: <%# mymonth + 1 %>
All the schedule from the DB is shown, using the following SQL:
SELECT DISTINCT day(mydate) FROM schedule WHERE month(mydate)=" + mymonth + " AND year(mydate)=" + myyear + " ORDER BY day(mydate) ASC"
But my problems are:
- i want to show 3 months backwards from th actual month
- when mymonth is 1 (January) 2011 for example, it would show December, November and October from 2010
- If for example, we are in JULY, it would show until APRIL backwards, and when on APRIL it wouldnt show the PREVIOUS button.
How can I bind radio buttons to an sqldatasource for update ?
View 2 RepliesI have the following client side code in .aspx page within a datalist itemtemplate that takes questions from the database like this:

The output is like:
1) What is your age group?

The ID's of the radio buttons are dynamic ("Q" & QuestionID). If there is no answer to a question then the GetVisible function returns false and the containing panel is hidden.
I have been trying to get rid of the html and replace these with asp:radiobuttons but it is not possible to set id's from databinding.. only simply. I was trying something like:
<asp:RadioButton ID="Q<%#Eval("ID")%>" runat="server" Visible='<%#GetVisible(Eval("OptionA").Tostring())%>'
Text='<%#Server.HtmlEncode(Eval("OptionA").ToString())%>' />
Here is the function that provides data:

but I'm finding it impossible to work with the html controls, i.e get their .text value from codebehind, or adding events!
better way to replace the html with suitable asp.net web controls or from the codebehind and output it. Or point me in the right direction?
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.

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 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?
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
