MVC :: Model Binding And Radio Buttons - Unable To Get Multiple Rows?
Apr 20, 2010
How to select more than one radio buttons and use model binding to attach the Roles to the model property public string []Roles?The difficulty i`m having is that though i`m having multiple rows, Only and only One radio button is selected and tha tof the last row. I have the following code:
I have a list of input type radio buttons in formview (edit mode) and i want to bind data from datasource that is assigned to formview. Can i bind html radio buttons using sql datasource?
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'
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 listing about 20 rows, each row represents an Order.Each row needs to have 3 buttons, each button click will perform a different action.I have 3 actions to handle each button post request, I am just unsure how to setup the Html forms for each button.
Should I create 3 forms for each button, per row in my listing?(that would mean 20 rows x 3 forms = 60 forms on a page)Is that 'ok' to do? (i.e. or is there a better way to do this?)
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
I have a complex page with several forms on it. The page is divided into sections, and each section has a continue button on it. The page is bound to a pageViewModel, each section addresses a different set of properties on the model. The continue button makes an ajax call to the controller, and the model binder binds it appropriately to the appropriate sections of the model. The section is refreshed appropriately. Finally, I would like to have a save button at the bottom of the page that takes all the forms, and binds all of the forms to the model. The model, at this point has all of the properties filled out, and can be processed accordingly. Can I accomplish this by some ASP MVC magic?
I have one view page (MyView.aspx) and many data sources to bind on this page. Lets say it has Books, Publishers, Comments, etc. Each one of those has an object which provides a List, List, etc. In my view, what are my optiosn for multilple model biding? I want to check to see if each one is empty, and then enumerate it. But I can't check Model.Count() because wouldn't Model be made of all those objects if I set the page to inheriet from? What are my options? Should I load each content area in a control/partial view? Or can I just dump each object into ViewData and then check the count by casting in the view?
Im struggling with a way to bind multiple rows of sql data to specific controls, what im trying to acheive is having a list of questions / answers in my SQL db and loading them into my web form to build a questionaire.
The data i load into the form depends on criteria like which questionaire is it (there will be 2 seperate ones) and what language should it be loaded in, this will be controlled using drop down lists and passing these parameters to the SQL select statement.
The problem i have is i am unsure which method to pull the data out of the question column in my table, and bind it to seperate controls row by row, should i use a SQLDataReader or load the data into a dataset, or run a stored procedure to pull the data?
Which is the best way to get data from sql and bind it to controls in this situation?
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 have the modal popup come up for searching something. Inside the popup (panel) I have a txtbox and a search button. I enter text and hit 'search' and the results are shown in a listview within the popup. Now every row in the list view has a button "Select". I want to click on one of those buttons to select a particular value.
Now on click of the button(within the listview), I tried calling a javascript function and doing $find('mdlPopup').hide(); , which makes the popup dissappear. But somehow the debugger takes me straight to Global.asax.Application_Error() and doesn't even give me a stack trace to see wht the issue is. And over that, the popup looks dissapeared, but the rest of the controls on the page are not enabled back. Strange?
I'm assuming, that the popup doesn't close as intended and it errored out (which took me to Global.asax.Application_Error() ), and is not enabling the rest of the controls in the page.So my question is, how do I assign multiple buttons in a listview to the okbutton (or cancelbutton) of a modalpopup extender?
i am developing a quiz website in which i want to display question and then radio buttons according to the number of choices of that question dynamically by accessing from db.

How to use radio buttons in grid view. i used asp:radiob button but the problem is that it selects all the radio buttons in the list how to select only one radio button at a time
I have a 2 groups of Radio Button controls on my web page that are dynamically loaded. They are contained within a DataList control. I have the "GroupName" property set for each of the groups, however, I am still able to click on more than one rdo within each group. I've set the "GroupName" property within my HTML markup.
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?
how to apply group name to html (input) radio button controls so that i can select any one of the available radio buttons?
I have input radios in a table. Each row contains two radios as follows. I want to select one from each row. But i am able to select only one radio button amongst all radio buttons present on all rows.
