AJAX :: Use Databound Radio Buttons To Control CollapsiblePanelExtender?
Aug 17, 2010
I am using .Net 3.5 in VS 2010. I would like to use a couple of radio buttons, that are bound to data, to control the Expand/Collapse of a CollapsiblePanelExtender.
I have found several threads on the web that suggest using JavaScript to control the CollapsiblePanelExtender with a RadioButtonList, but I cannot $find the control in the JavaScript.
I have also found several threads that suggest using custom radio buttons, but I don't see how to do the databinding for these.

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.

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 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 am trying to use a collapsible panel extender within a custom server control. I've used the extender elsewhere with no issues but when I try to add the control to my panels collection of controls in my custom control, my page crashes. Take it out and no error. I'm adding other controls to the panel...literals, labels, etc. This, however is the only ajax control I am using. Is there something I need to do as far as registering the extender with the script manager (on the master page)?

I have made a user control using CollapsiblePanelExtender control. I am getting a small issue, that the panel that expands is not relative to the control. It always open on left side of the page. My control is in different location in different pages. How can I make sure that the expand and collapse is with respect to the control? I see "left: -36px" in the style attribute of "SettingsContentPanel". How can it be relative and doesn't break the code.

is it possible to dynamically create radio button options that are dependent on a value within a database? For example 'b' is stored in a field so then 'a' will also be a radio button option, 'd' is stored in a database field so then the other radio button options will be 'a', 'b', 'c'....the radio button list will change depending on the value stored in the database field.

I am using Radio buttons inside a panel in a web page. (Since group boxes are not there). But when I click on each radio button they all are checked. They are not acting as a group but single units.

I'm trying to implement accessibility (keyboard only) ability on my site, but I'm having problems with Radio Button lists. When using radiobuttonlists, when initially, none of the radio buttons is selected, I am able to tab through every single value and select one upon hitting "enter". However, after a value is selected, I can only tab to the selected values, which presents a problem if I want to change the selected value.
From what I understand, radio buttons are grouped at the container controller level, thus when it is considered a group, only one can be selected at a time.

I have a set of radio buttons (individual buttons) in asp.net. These buttons have a group name (if that matters). What I need to happen is, anytime a user selects a radio button, I need some jQuery to be called. I am not doing a page refresh when the user selects the radio button, so I need this to be done on the fly. I have tried a "CheckedChanged" event in asp.net and can not get it to fire. I have also tried:
if ($('input:radio').attr('checked') === true) {
var checked = $('input:radio:checked').val();
}
however it only works the first time the page is loaded, not when a user selects something other than the default. What Can I do to fix 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)

Case "TextBox"
Dim tbAnswer As TextBox = New TextBox()
divAnswerContainer.Controls.Add(tbAnswer)
