Web Forms :: Radio Buttons In User Control With Complicated Layout?

Mar 8, 2011

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?

Web Forms :: Clicking Radio Button In Web Control Causes All Other Web Control Radio Buttons To Fire Postback?

Feb 8, 2010

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:


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.

Web Forms :: Image Control With Radio Buttons?

Jan 28, 2011

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.

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.

Web Forms :: Radio Buttons To Turn On / Off Groups Of Controls?

Dec 28, 2010

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.

Creating A User Control With Variable Layout?

Oct 13, 2010

I have a user control which contains a number of child controls. I want to be able to change the layout of the control (i.e. change the markup surrounding the child controls) via a property of the user control, but I don't want to have to duplicate the child controls themselves. This precludes using, say, a MultiView with different versions of the layout in each view, since in that case I'd have to duplicate the controls. I'd also rather use markup than emit the code for the control directly (as you'd do in a server control).

To give a contrived example, say I have a label and a textbox. In one layout, I want the label and textbox to be contained by divs and laid out on top of each other. In an alternate layout, I want them to be contained side by side in a table.

Should I just go ahead and duplicate the controls between each view? It seems like a violation of the DRY principle, but I'm not sure if I have much choice. A partial solution would be making the views of a multiview into naming containers so that I could at least save myself the time of having to prefix the duplicate control IDs with something to make them unique.

I also have tried another method as follows:

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 ID="TableCell2" CssClass="answer" runat="server">
<asp:RadioButton ID="PatientNo" GroupName="Patient" runat="server" />

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?

Web Forms :: Process Radio Buttons As 'group' Allowing For Multiple Selections?

Feb 25, 2011

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

Forms Data Controls :: Radio Buttons Are Not Mutually Exclusive When Used In A Repeater (or ListView)

Feb 15, 2011

"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)..

Web Forms :: ASP:TABLE And Get The Postback Data From A Programmatic Generated Radio Buttons In TableCell Object

I am having a bit of trouble trying to get teh postback data from a programmatic generated radio buttons in TableCell object. I have the following ASP user control:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="wcntrlCallFlow.ascx.cs" Inherits="CallEvaluation.wcntrlCallFlow" %>

I generate the TableRow and TableCell base off XML data file. When the submit occurs I can not access the data values from the radio buttons that are generated. I try to get the data in the following manner:

this.value = 5;

I notice that in the Request object the table row name is passed back like: "wcntrlCallData1$wcntrlCallFlow1$CallFlow".
