AJAX :: Updating Method On Master Page After Few Seconds With Timer Or Custom
Jan 6, 2011
I m facing problem updating a method which shows the count on master page. That method is bind to treeview control.Whenever a data is saved count is incremented to one. but method gets refreshed only when there is a postback. I want it to be updated after every few seconds or whenver there is data saved. there is pretty gud solution with custom ajax that is with json. But that is not possible with exiting solution.i have to redesign the complete treeview structure in html. And with timer control of ajax whole page gets refreshed.

VS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.

I've watched Joes video on [How Do I:] Use the ASP.NET AJAX Timer Control? I'm trying to do a similar thing but using this control on a Masterpage. I then create Content page from the master, but the banners do not show on this page.

I am trying to get my head around the ASP timer control. What I am trying to achieve is to get a page to reload every 60 seconds but change the url querystring everytime between 3 values
i.e. scroll through
server/page.aspx?value=1
server/page.aspx?value=2
server/page.aspx?value=3
how I have though to do this is to use ASP code to grab the querystring value, and then create the next url. But I am having trouble passing that newly created url to a refresh control. im guessing HTML meta refresh is out of the question as I am using a variable. So from what I can see my option is to use the ASP timer control to count down (after the page has loaded) and after 60seconds load the next url.

I have master page that has a Telerik radmenu control.
[Code]....
On the content page, I populate this control with menu items.
[Code]....
This part works. The menu items are populated with the correct navigate URLs. The content page allows users to change parameters that are inside an update panel.
[Code]....
After the values are updated, the LoadShareMenu function is called again. I have verified through the debugger that the function is being passed the updated values and that the returned RadMenu is populated with the correct NavigateURLs. However, the RadMenu control on the webpage remains unchanged. The original NavigateURLs remain.What final step do I need to do to cause the RadMenu to update?Here's the code for the FindControlByID function:

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.

I have an "Edit" page that uses a FormView bound to an EntityDataSource. The page is called with the ID field of the record to edit in the query string: "EditEmployee.aspx?ID=10". The EDS the FormView is bound to is using: AutoGenerateWhereClause=true and a QueryStringParameter. Below the FormView I have a ListView that contains some child records of the FormView. The ListView is bound to a seperate EDS and also uses the (same) QueryStringParameter.
The problem I am having is when this ListView attempts to Insert or Edt a column I receive an error because I don't have the ID field (EmployeeID) of the parent bound anywhere in the ListView (and obviously, it is setup as a ForeignKey so it fails, like it should). Any advice on the best way to get this ID (EmployeeID) column bound in the ListView? There are many things I can do in code behind, but I would like to solve this in the markup if possible. I can move the ListView so that it is inside of the FormView if necessary.

I have a label within my master page that is part of our footer. In the footer, we are wanting to display page specific information. So as you make your way around the site, the footer will contain content about that page along with other data that is universa on the entire site.I had a somewhat similar question some time back that i posted here..
http://forums.asp.net/t/1615850.aspx it was for a shopping cart of sorts..
cartct.Text = ShoppingCart.Instance.Items.Count().ToString() + " Items In Cart";
If Label is in master page, you have to use FindControl to get the Label and udpate its text
((Label)Master.FindControl("cartct")).Text=String.Format("{0} Items In Cart",ShoppingCart.Instance.Items.Count() );
once you select another page, you dont have it anymore,If you want to share data across different pages, consider using Session to save Items count.

I have an Image control (for logo) on the master page as follows:
<asp:Image ID="imgLogo" ImageUrl="~/Images/logo.jpg" runat="server" />
I am allowing my users to upload their own logos. So on the page where they upload their logo I want to replace the existing logo with the newly uploaded logo. I tried the following but none of them worked:
1) Did a Response.Redirect back to the same page and it didn't work.
2) Tried the below code after the image upload is complete and even this didn't work:
Image imgLogo = (Image)Master.FindControl("imgLogo");
imgLogo.ImageUrl = "~/Images/newLogo.jpg";

I want to create a page with a stopwatch. I have a start button and I have a starttime in my model. Now I want to display the running timer in my view and it should reflect the starttime from my model. How do I update the timer with my starttime from my view right after I have pressed the startbutton, and how do I get it to update each second? Do I need to use jQuery for the update?

I have an ASPX page with two columns. The left column has a GridView control that contains a list of article titles as LinkButton controls. When a LinkButton control is clicked, the content of the article is displayed in the right column. Each of the columns
is wrapped in an UpdatePanel. So far everything is working .
Each article title has further descriptive text that is defined in the code-behind as labels within a Div object. Each Div is added to a PlaceHolder object on the master page. References to the Div objects are added as attributes to the LinkButton so that JavaScript is executed when the user rolls over the title and the Div object with the descriptive text is displayed.
The rollovers are working fine and displaying the correct text for the first GridView page. However, when I click a button in the GridView's paging row to advance to the next page of the GridView list, the rollovers are not updated. The text is what was defined for the first GridView page of titles. How should I get the PlaceHolder objects to update when the UpdatePanels are updated?

In my child page i have an imageButton, which is surrounded by the UpdatePanel. When the user clicks on the image button a record is removed from my database.
<asp:Content ID="Content1" ContentPlaceHolderID="Content" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers><asp:AsyncPostBackTrigger ControlID="btnRemove" /></Triggers>
<ContentTemplate>

In my master page i have literal control which displays the records for the current user (something like Records: 10)
The RecordsCount control is updated on the page Load event of the MasterPage
Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
RecordsCount.Text = GetRecordsCount()
End Sub
How can i update the RecordsCount control? I mean i use postbacks for removing records from the database. And currently the RecordsCount control will be updated if the user hits the Refresh button of the Internet browser. How could i apply the Jquery Highlight on the RecordsCount control when the user clicks on the btnRemove button on the child-page?
UPDATE: Well the first question is solved by using javascript

I'm searching for an example with an client timer that ticks synchronous with an server timer. Also there must be a button on the client side which can reset the server timer to an default value, and with this it also resets the client timer ofcourse. I tried it myself but it seems that there is some postback delay which makes it impossible for me to make it atleast look like it goes synchronous.
I hope somebody got an example for me, the button part is really important because by pressing that button the delay comes.
