AJAX :: Updating Content Within A Placeholder (updatepanel) Using A Timer?

Feb 1, 2011

GOAL: on a web page (vb.net) content in a placeholder will refresh with a different .ascx (user control) every 30 seconds (rotating 3 in total) and of course i dont want to refresh the whole page, just the placeholder.

I'm new at AJAX (that's my first problem - lol)

I set the timer up to call a function, but not sure how to go about refreshing the placeholder with a different ascx file. I'm sure i'll be using UpdatePanel to do this, but haven't been able to figure this out. Easy to replace a value in a label using AsyncPostBack trigger, but nothing on how to achieve this.

C# - Prevent Updating The Content Of The UpdatePanel From The PostBack Of The Page?

Jan 30, 2011

How to prevent the content of the UpdatePanel from the PostBack which is occurred in the whole page ?

I have the following code:

<head runat="server">
<title></title>
<script type="text/C#" runat="server">
// I don't want it to call this event handler

[Code]....

The previous code will write in the TextBox2 in spite of it exists inside an UpdatePanel with Conditional for UpdateMode.

I want it to update only when I call UpdatePanel1.Update();

AJAX :: PlaceHolder Inside UpdatePanel?

Nov 8, 2010

TThis time I'm facing some unusual behavior with a web page that I'm developing. I have a table with several controls and gridviews and stuff. At some point of the table, i have to show some rows (they were hidden) when the users clicks a button. I was doing this with a PlaceHolder, but now i have to do it without the postback being displayed. I thought: "That should be easy, all i have to do is to put the PlaceHolder inside an UpdatePanel, and that's it" but no, no no nooo!! NOTHING IS THAT EASY!!! It actually works but it puts the hidden rows at the top of the page, not where they suppose to go!!My code is the following:

<asp:UpdatePanel runat="server" ID="uplAutoridadesAmbientales">

AJAX :: Timer Results In Updatepanel Gives Full Postback

Jan 19, 2011

I have a quite strange situation where I have the following code:

[Code]....

This gives a quite strange result: Every 5s my whole page gives a full postback. When I comment in (activate) the asyncpostbacktrigger, the updatepanel does not give a full postback. In the PlayerItems_ItemDataBound I have the following code (which, I do think, do not matter):

[Code]....

When I create a NEW updatepanel, ItemsUpdatePanel1, it does not fire a full postback without the timer. I can even start copying items from ItemsUpdatePanel to ItemsUpdatePanel1, and suddenly the full postbacks happen. I tried 2 seperate times, and they started happening at different times. I simply want the UpdatePanel NOT to give a full postback, even without a timer.

VS 2008 Simple Image Toggle With AJAX Updatepanel And Timer

Aug 10, 2010

I don't understand what the problem is with this. It should be a simple operation yet it doesn't work.

I found samples on how to do this, when I apply the sample, it doesn't work.

In my page I have this:

[code]....

When I run the page, after 5 seconds it switches from the first image to the second image and never switches back to the first image.

When I debug with a break in the code-behind, it looks like the timer ticks twice for every tick. So, when the image is sample2, it then changes back to sample1 and then immediately ticks again and switches back to sample2 with no update-panel refresh in between.

AJAX :: Fileupload In Updatepanel With Timer Doesn't Work At The Second Time

Jan 23, 2011

I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.

I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.

However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

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]....

AJAX :: ToolkitScriptManager Fails On Updating UpdatePanel?

Oct 21, 2010

this is my first post in this forum, even though I often search for helps and clarifications over its threads. And many times they are definitely useful!!I had a <asp:ScriptManager> in may MasterPage, wich was used to manage various UpdatePanels I have either in Content pages or in MasterPage.Today I inserted a CalendarExtender, so I had to replace the ScriptManeger with the AJAX ToolkitScriptManager.

At the beginning it seemed to work fine (the calendar pop up and others controls got updated properly). Then I noticed that the nodes in various TreeView are not expanding any more. The TreeViews objects are placed inside an UpdatePanel, in order to expand each node without refreshing the whole content page. And, while a node expands, an UpdatePanel containing a GridView in the content page gets updated.Now, with the new ScriptManager they do not expand, but when clicking on a single node the GridView is updated properly.Here some pieces of code:

Controls registered as triggers.I know I can use only one script manager per page,

AJAX :: UpdatePanel With AsyncTrigger: Firing But Not Updating?

Now, in each postback this is set as a datasource (it is not loosing its datasource because of some timer).What my problem is: Even though the Page_Load event is being fired and I can see the datasource has changed, the content I see in the radiobuttonlist stays the same!

AJAX :: Image Control Not Updating In UpdatePanel?

Jan 15, 2010

I develop an ASP.NET web application. The server side receives a stream of image data (JPEG frames as byte arrays).

It should processes them and send the images to the client side periodically.

For displaying these images on the client side I tried to use an approach similar to this described in the post "Improve your Image(s)" (http://steveorr.net/articles ImproveYourImages.aspx) by using an auxiliary ASP.NET page for the purposes of the server side image processing.

When I used a client side button to request the image ocntrol (imgCameraCapture) update with its URL pointing to the processing page (GenImage.aspx, as in the above post), everything worked fine (with exception of the whole page re-rendering on each button event). The image was updated.

For a periodic update of the client image control on the main page I put in an ASP.NET AJAX UpdatePanel andset it to update conditionally by triggering to an ASP.Net AJAX timer (10 seconds) event in order to achieve a partial page update (just the image).

II used the timer tick event handler to update the image by invoking the separate ASP.NET image data processing page there as in the button click event handler. But in the timer tick event handler the processing page was not invoked and the image was not updated.

This is the C# code behind executed in the button clik and timer tick event handlers:

imgCameraCapture.ImageUrl = "~/GenImage.aspx";

AJAX :: AsyncFileUpload - Clear Text On Sever Side - UpdatePanel - DetailsView Updating?

Dec 11, 2009

I have been looking for a way to clear the text from an AsyncFileUpload located inside of a DetailsView inside of an Update Panel so that I don't have to remove the update panel to update my filesystem and database. The problem is that every solution I have seen involves the use of JavaScript and in my limited experience I have found JavaScript to be incompatible with controls situated inside of DetailsView templates that are not visible in DefaultMode (ex: item template by default where you must click a button to get to to edititemtemplate).

What I want to do is clear the text of an AsyncFileUpload after the record is updated ideally on the DetailsView item updated event. I tried session.clear, but that did not work. What I want to is a way to upload files and update records at once without a full page postback.

My current code behind is as follows.
