AJAX :: Programmatically Assign AsyncPostBackTrigger In C#?

Jan 29, 2011

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.

AJAX :: Adding AsyncPostBackTrigger Programmatically?

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:

AJAX :: Update FilteredTextBoxExtender From AsyncPostbackTrigger?

May 28, 2010

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?

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?

AJAX :: UpdatePanel AsyncPostBackTrigger And Gridview Not Updating?

Mar 8, 2011

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>

[Code]....

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

C# - Programmatically Add A Button To A Gridview And Assign It To A Specific Code-behind Function?

Mar 10, 2010

In runtime I'm creating a DataTable and using nested for-loops to populate the table. This table I later assign as DataSource to a gridview and on RowDataBound I assign the value of each cell. I want to know how I can give each cell a button and assign that button to a codebehind function. I'll have 12 buttons and each one will contain a different value. I would prefer if they all call the same function with some kind of event that stores the cell-specific value. This is the code where the Table gets created:

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:

Fileupload Using Input File / Refer To 'AsyncPostbackTrigger' Or 'SyncPostBackTrigger'?

Aug 10, 2010

I am using VS-2005.

In my website I have used the html input control with type=file.

The problem is that when I place this control inside an 'UpdatePanel' the 'PostedFile' property becomes 'Nothing' on postback. So in order to get things working I have removed the 'UpdatePanel' and things are working fine.

However, I am interested to know what kind of workaround is required if I were to use an 'UpdatePanel'? In one of the threads at forums.asp.net I found that we need to set a 'PostBackHandler' for the update panel. I have no idea how to implement this. Does it refer to 'AsyncPostbackTrigger' or 'SyncPostBackTrigger'?

Can someone give an idea how to implement this?

AJAX :: How To Dynamically Assign The Visibility Of The TabPanels In Page

Apr 1, 2010

I'm trying to dynamically assign the visibility of the TabPanels in my page. The code below sort of works, but not correctly (refer to image).

It is able to hide the actual tab, but the header still appears (though unclickable). I need for the header and the tab to be hidden.

I tried to use "tb = (AjaxControlToolkit.TabPanel)this.page.findControl("TabPanel1").Visible = true"

And get this error Object reference not set to an instance of an object.

I can be pointed to the right direction.
