Getting Selected Item in radiobuttonlist on content page using javascript

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :ASP.Net
I am trying get the selected value from a radiobuttonlist on a content page using javascript. Here is my initial code, which does not recognize the control. The js is located in a separate file and there is a link on the content page pointing to the js file. Thanks, function GetRadioButtonValue() { var radio = document.getElementsByName('<%=rblPayType.ClientID%>'); for (var j = 0; j < radio.length; j++) { if (radio[4].checked) { alert(); return; } else { return; } } }

Create buttons for "new item" which create a new page of a specific content type

We have a Pages library (wiki) which supports a few content types (and page layout associated). We want to enable users to click a button for example of "new custom enterprise wiki page" - so a new page of content type article will be open in edit mode. Can someone help how to develop? (it has to mimic the behavior that happens when user creates new page from the Ribbon or Site actions and has to choose the content type, it also has to keep the new page in edit mode and not just create it).  

Accordion control access in Javascript using Content page

Hi, I struggled with some javascript issues, and discovered that the problem seemes to come from a failed ajax control access.Here's my problem:I have a master page and a content page.In my content page, I have an accordion with 2 panes.1rst pane: a textbox and a validation button;                     I want the button to fire javascript function without reloading page (using "return false;");In my master page, I put my ToolkitScriptManager.In my content page, I put my script containing the functions.The problem is that it seems like I can't access the accordion control in my js functions, whereas I can access my textbox value...Here is my source:<%@ Page Language="C#" MasterPageFile="~/Default.master" Title="CLEOR RH | Home" CodeFile="Default.aspx.cs" Inherits="Default_aspx" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> <asp:Content ID="Content1" ContentPlaceHolderID="Main" runat="server"> <script type="text/javascript"> var step1 = false; function pageLoad() { var accCtrl = $find('AccordionCtrl_AccordionExtender');

C# data bound combobox: display selected item text in separate label.content


I am new to C# but I'm resisting the urge to run screaming back to VB.NET. I'm working with a WPF application using C# code-behind and a lot of binding to a SQL 2005 database backend.

GOAL: I have a comboBox bound to a tbl_Systems entity which provides a list of systems for user selection. When the User selects a system from the comboBox I want to display the selection's text in a separate Label. The big picture is that several comboBox selections will be used to build a query string that will populate a listbox. So, I want to display these selected values in the Label so the user can see the query string they have dictated.

PROBLEM: When I set the Label content property to the comboBox SelectedItem property the entity tbl_System is displayed in the Label not the comboBox selection text.

SUSPICION: From reading similar examples in VB I suspect that the comboBox SelectedItem is actually a "datarowview" or the C# equivalent. But I don't know how to translate this explanation to C#.

The UI XAML comboBox properties are set as such:


When Saving a Page that Contains Javascript, the Content Rendered is Repeated


Each time I save a page that contains javascript, the content rendered is duplicated. For example, I added the following javascript (to display today's date) into a content editor web part:


<script language="JavaScript">
function mdy(todaysdate) {
//calls the function mdy why to get our date
return todaysdate.getMonth()+1+"/"+todaysdate.getDate()+"/"+todaysdate.getYear()
}</script><b><font size="2"><script language="JavaScript">
sampleDate1=new Date()
document.write ("Today's date is "+ mdy(sampleDate1))</script></font></b>


I then click on stop editing. When I go back to edit the page and then click on stop editing, "Todays date is ...." keeps repeating. This happens each time I edit the page.

Has anyone else encountered this problem? If not, do you know what could be causing it?

Databound dropdown list inside detailsview filtered dependent on selected radiobuttonlist item


It's driving me mad.  I have a detailsview bound to an sqldatasource. One of the items on the data table is to get its value from a dropdown list, so I created a template field and entered a dropdownlist, then bound that to a second datasource with the selection values in it. As the values can be male or female related, I have an unbound radiobuttonlist above the dropdownlist with two values - male or female - retunring an d"m" or an "f" and I want to use this to filter the records coming from the second data source for the dropdownlist.

I can't use a normal SQL control parameter on the datasource as the selector (the male/female radiobuttons) are in the detailsview and therefore "invisible".  I set up a normal control parameter with "none" as the type.  I then set the "autopostback" value to "true" for the male/female radio buttons and tried writing in the code-behind for the "maleorfemale_SelectedIndexChanged" event and using debug lines revealed that I was getting the "m" or "f" I needed by using "findcontrol", so that's fine.

I also tried adding in the "selecting" event for the second datasource to use the value of the radiobutton item, but although the "selecting" event fires

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?


Passing Linq Statement between master and content page


I usually work with windows forms, and am just starting to work with ASP.Net, so appologies if this is a dumb question!

I have a master page which has a search button on it. The results of this are built up using a Linq statement and if there are any results, I want to display the results in a contents page.

On the masterpage, I have the following code:

Private _res

    Public Overridable ReadOnly Property SearchRes()
            Return _res
        End Get
    End Property

 Private Sub DoSearch()
   'some code to get a linq result

    If res.Any Then
            _res = res
            Server.Transfer("SearchResults.aspx", True)
            'no results
            LabelNoRes.Visible = True
        End If
 End Sub

On the SearchResults.aspx page I have this code.

Dim m As pxSite = CType(Page.Master, MasterPage)
        If m.SearchRes IsNot Nothing Then
            Label1.Text = "Results found = " & m.SearchRes.Count
        End If

m.searchRes is always nothing. 

What am I doing wrong here?


Re-positioning an HTML container with javascript onresize with a Master page.


I have an HTML <div> container that I float to the right of a gridview.  When the browser window is maximized, it looks fine.  When minimized, the gridview positions below the floating container and most of the data is pushed off the bottom of the browser - you have to scroll down to see it.

If I position the floating container above the gridview it looks fine in a minimized window, but looks real bad when maximized.

What I want to do is use a javascript: onresize event to re-position the floating container up or down depending on the window.inner.width AND do it with a Master/Content page structure AND do it for only the one page where needed.

I can capture the onresize event and display the window dimensions but haven't figured-out how to do it with a Content page that still uses the Master page.  I think I'm having a very "thick" week...

ASP.NET Proxy Page - Used for Cross Domain Requests from AJAX and JavaScript

The article ASP.NET Proxy Page - Used for Cross Domain Requests from AJAX and JavaScript was added by Aamir Hasan on Thursday, August 19, 2010.

One of the pain points with developing AJAX, JavaScript, JQuery, and other client-side behaviors is that JavaScript doesn't allow for cross domain request for pulling content. For example, JavaScript code on www.johnchapman.name could not pull content

ASP.NET 4.0 Menu Top Level selected item style


I want to apply a css class to the level 1 menu item (parent) when it or any or it's children are selected.

I've looked at MSDN documentation and any number of examples and walkthroughs but I haven't come up with a way of managing this. I was thinking something like this might work but the style is not being applied to the parent. To further complicate matters, if I try to apply a css style to StaticSelectedStyle it doesn't pick it up at all.

Menu Markup:

<StaticSelectedStyle  Font-Bold="True" ForeColor="#3333CC" />

Code Behind:

        protected void MenuItemClick_NavMenu(Object sender, MenuEventArgs e)


            MenuItem parentItem = e.Item.Parent;

            if (parentItem != null)


                parentItem.Selected = true;
