AJAX :: AsyncPostBackTrigger With A RadioButtonList Control?
Dec 28, 2010
I am converting an old payment page from classic ASP to ASP.NET. The page includes three radio button options (credit card, purchase order, bill me). The old page uses javascript to enable/disable the appropriate input fields depending on which payment option is selected. For example, if the payment selection is changed from "credit card" to "purchase order", the credit card fields are disabled, and the PO number field is enabled.
I want to mimick this behavior using ASP.NET + server-side AJAX, so I created RadioButtonList for the payment options, and put all the data input controls (credit card number, purchase order number, etc.) within an UpdatePanel. The UpdatePanel has an AsyncPostBackTrigger with ControlID set to the RadioButtonList, and an EventName specified which tries to enable/disable the appropriate input fields depending on which payment option is selected. This doesn't seem to work because changing the radio button selection doesn't seem to fire this trigger.
Is it possble to utilize AsyncPostBackTrigger with a RadioButtonList control? If not can you suggest a way to handle this scenario for dynamically enabling/disabling form inputs?

I have a TabContainer with a few TabPanels. Inside the first TabPanel there is a GridView that have a LinkButton called "Subject".
Now when this "Subject" is clicked I want to change the TabIndex to another TabPanel so I have created a clickevent for this below.
I want to change TabIndex using an UpdatePanel to not have to do a fullpage postback.
So I need to put the "Subject" in the AsyncPostBackTrigger but it says it cant find the control so I wonder how I would do this for this LinkButton "Subject" ?

In my UpdatePanel, the user can page, sort and filter a gridview all using AJAX, then they select a row which causes the post to post back and a textbox to be populated with the rows ID.
Problem is, it seems I can't register both an AsyncPostBackTrigger and a PostBackTrigger to the same control - so how would I accomplish this? Here are my triggers so far:

I have an ASP.NET Label on my form, which is wrapped in an UpdatePanel. The UpdatePanel has two AsyncPostbackTriggers which reference two DropDownList controls. Based on the combination of selected items in both DropDownLists, I'm updating the Label. I also have a FilteredTextBoxExtender referencing an ASP.NET TextBox that's, by default, only allowing numbers. Now, along with updating the Label based on the combination of selected items from both DropDownLists, I'm also changing the FilteredTextBoxExtender's FilterType to Custom | Numbers and ValidChar to a hyphen, to allow both numbers and a hyphen (for phone numbers). Remember that I have both DropDownLists as AsyncPostbackTriggers for the UpdatePanel. This works perfectly fine doing a regular postback, but if I add those two DropDownLists as AsyncPostbackTriggers, the FilteredTextBoxExtender is not working properly based on the FilterType and ValidChar properties. It only allows just Numbers, which is the default. Is there anyway around this without having to do a regular full postback?

I'm dynamically creating image buttons and want their click event to update an image in the update panel where only the panel updates- not the whole page.
I have created the image buttons click event and got it so that it updates the image in the update panel, but I can't seem to create the triggers- I keep getting the error 'Multiple Controls with the same ID' and I can't understand why.
Here's my code:

I want to try and use an updatepanel. So I have surrounded this code with an updatepanel.
Now I need to put "LinkButton57" as AsyncPostBackTrigger. It seems that I cant put that in the HTML code in the Trigger tags as the updatepanel only searches for parenting controls.
This LinkButton57 is located deeper in the control hiearchy as you can see here. So I am trying to put this programatically in the Page_Load event.
Now if I run the below code, I get this exception(Object reference not set to an instance of an object) and wonder if I could be thinking right here and just miss some details perheps? Will be happy for answer.

I have a very simple application that works almost all the time. I am using an UpdatePanel. My script manager is configured to enable partial rendering. My UpdatePanel is configured for conditional update mode. My asynchronous trigger is a timer that runs every 3 seconds. I track unhandled exceptions in the database. I am not getting any unhandled exceptions. Nor am I getting managed exceptions. Now, I had two users side by side running the application today. I had one record in the data queue. The first user did not get updates; her grid did not update. The second user did get updates. The only difference was that the first user was logged in for a long period of time. The second user logged in just before the test. I reviewed the IIS log file and both users were polling the page every 3 seconds for the same data. So why didn't the first user's grid update? The code follows.
<asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeout="30" EnablePartialRendering="true"></asp:ScriptManager>

In my code behind I have the following timer logic. [Code]....

What does that means below warning:
Element 'AsyncPostBackTrigger' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.
My app is working properly but visual studio showing warning like that.

In my database table I allow null for the gender field. However, when the form is being edited, it gives me an error since the RadioButtonList does not have a match value for null. How do I get around this? Is there a way to have null value in the RadioButtonList control?

I am developing a website using asp.net and C#.I am using a RadioButtonList control. The code snippet for RadioButtonList is shown below
<asp:RadioButtonList ID="RLCompareParameter" runat="server"
RepeatDirection="Horizontal" meta:resourcekey="rsKey_RLCompareParameter"
AutoPostBack="True"[code]...
There is a button in the same page. While clicking on that button i want to display an alert message based on the selected radio list item using javascript. Some part of my javascript function is shown below
var RLCompareParameter = this.document.getElementById("<%= RLCompareParameter.ClientID %>");
if (RLCompareParameter.SelectedValue == "Forms") {
if (document.getElementById("<%= lbAvailableForms.ClientID %>").value == "") {[code]...
But the if(RLCompareParameter.SelectedValue == "some value") always false. i think there is no attribute like selected value for RadioButtonList control.

I have a radiobuttonlist control on my control, where the datasource is a collection, and I am using the DataTextFormatString to set the text field to a hyperlink. All this bit works, but where I am struggling to work is to add to the url path the value from the datavaluefield. Nothing I try works! Does anyone know how to set the datavaluefield into the url? Further, and one last question, my radiobuttonlist control is in a wizard step, and when the user clicks on a hyperlink, I want it to go on to the next step, all that is happening is that the link is going back to the first step.
