Ajax Accordion - Multiple controls with the same ID '_content' were found

Posted By:      Posted Date: September 08, 2010    Points: 0   Category :ASP.Net
Hi I'm dynamically adding accordion panes to an Accordion Control. When I add a single pane, no problem but trying to add 2nd pane I get the exception: *Multiple controls with the same ID '_content' were found* I've tried assigning unique Ids to the panes as follows but not joy. Can anyone please help? Thanks Rob.    if (User.IsInRole(@"arcpet\RDLM - Tradecapture Initial Margin Users - Security")) {      //build header for pane      AccordionPane pneTCaptureInitalMargin = new AccordionPane();      pneTCaptureInitalMargin.HeaderContainer.Controls.Add(new LiteralControl("(TCIM)T/Capture Initial Margin"));      pneTCaptureInitalMargin.ID = "AccordionPane" + Guid.NewGuid().ToString();      pneTCaptureInitalMargin.HeaderContainer.ID = "HeaderContainer" + Guid.NewGuid().ToString();      //build content for pane      pneTCaptureInitalMargin = AddHyperLink("Trade Books & Markers", "TradeBook/TradeBook.aspx?4", pneTCaptureInitalMargin);      acc.Panes.Add(pneTCaptureInitalMargin);           pneTCaptureInitalMargin = AddHyperLink("+Create New Records", "TradeBook/TradeBookDetail.aspx?acPane=4&type=new", pneTCaptureInit

Need help regarding C# / AJAX Dynamic Controls creation


radiobuttons is assigned before page init.. 

public partial class Default : System.Web.UI.Page
//Assign values as a specific Dynamic WebControl Creation.
List<RadioButton> radioButtons = new List<RadioButton>();
List<CheckBox> checkBoxes = new List<CheckBox>();

Then I created a class that would dynamically create a table containing the available flights depending on session.. (See CallPageLoad())

The placeholder and button is inside the UpdatePanel...

on the button inside the update panel, (btnSelect)

i have this code which works... 

protected void btnSelect_Click(object sender, EventArgs e)

Label1.Text = Convert.ToString(radioButtons.Count);

It detects the number of radiobuttons that were dynamically created...

But when I use the following code inside the BtnSelectClick event...

//PLS HELP.......
foreach (RadioButton button in radioButtons)
if (button.Checked == true)
Label1.Text = "You select... " + button;

Autocomplete with multiple word suggestions, How can we do in Asp.Net with Ajax?


Hi All,

Could you please let me know the process to get multiple word suggesions for a text box in asp.net using Ajax.  

Actually I got a solution for that,


But it used Atlas. When I am running with this code in my application, it is conflicting with Script Manager that is already there in Masterpage.

How can I overcome that problem. Is there any built-in solution in latest versions of Ajax?


Thanks in Advance,

Sateesh Nagalla,

AJAX update panel and update progress controls

I have writtena Crystal reports web application, that prompts ths user for parameters and then apply them and exports the report to a folder as .rpt and then display the report. I prompt the parameters on one screen and then display the report on another page. I have the AJAX update panel and update progress controls in the parameter page. When the user enters the parameters and click on ok, I export the report and then loads the report to a session report document and transfer the user to the second page where the report is displayed. I use the following code to do transfer to the seconds page. I have excluded the report load and parameter assign code here.rpt.ExportToDisk(ExportFormatType.CrystalReport, "c:\reports\testrep.rpt") Session("rpt") = New ReportDocument Session("rpt").load("c:\reports\testrep.rpt") Response.Redirect("show.aspx") In the second page I have the following: rptViewer.reportsource = Session("rpt") My problem is this works one time and then stops working the second. What I found out was it comes to the statement: Response.Redirect("show.aspx") But it does not even load the show.aspx page. It stays on the parameter page. There are no errors displayed. I could not see any errors when I debug the application also. And out of the blue it works
