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.

Basically I am trying to execute this code:
[Code]....
ERROR:Error 1 Cannot create an object of type 'System.Int32' from its string representation 'Convert.ToInt32(ViewState["RefreshInterval"])' for the 'Interval' property.
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.
My popup panel is disappearing everytime the timer ticks in an updatepanel.How can i solve this problem please friends.

I have a countdown timer inside updatepanel. When it reaches 00:00:00, it processes a huge amount of data and that point of time, i'd like to disable the submit button outside updatepanel. Simple btn.enabled = false is not working.

View 1 RepliesI am using a timer control on one of my updatepanels in the asp.net website.
my problem is that behind the scenes the postback is a full postback, therefore any content that is placed under any other UpdatePanel is refreshed, as well.
How can i specify the timer functionality ONLY to the specific update panel, leaving other update panels, which do not contain a timer, unrefreshed.
i want to display time on my screen and therefore i used timer control inside update panel and set my timer interval to 1000 but the time displayed after 3 seconds i mean 56 -53-52-49..... how to solve this below is the code
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick">
</asp:Timer>
<asp:Label ID="Label2" runat="server" Font-Bold="True" Font-Names="Microsoft New Tai Lue" Font-Size="Large" ForeColor="royalBlue" Height="25px" Width="162px" ></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
I'm having a problem where users with a slow connection aren't getting my image feed properly.i'm sending them new images every second to a picturebox inside an Ajax Update panel, using an Ajax Timer.so if their connection is really slow, one image doesnt load fully before the next one comes in, so they never get the whole picture...And for people with a faster connection, I would like to increase the update rate, and currently I see no way of dynamically setting the update rate.
View 1 RepliesI'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.
View 6 RepliesI have an ASP.NET form with several update panels. All works great.I use a timer and have it handle some periodic upates. That works correctly too. However, I appear to get an error when I leave the page open running in the debugger. Specifically the above JScript error 12030.I'm not clear how to find the source but I assume it is because my page has logged out. If I refresh I go back to my login page.So, does this sound like the cause? If so, how to I address this?

View 25 RepliesI'm having a serious problem with my ASP.NET AJAX application.There is an javascript function in my application needs to be executed after the Timer_Tick event. Here's the code behind:
[Code]....
When I call the javascript function 'UpdateValue' for the first time(at onload page event), it works correctly. But after the Timer_Tick event, it does nothing. This is the HTML code:
[Code]....
What's the problem with the ScriptManager or the Timer_Tick event?
Here upon loading the page there will be 4 panels having their own timer controls (having interval 1000) for incrementing a variable "a". But the problem is that, as I have used static variable that's why all the timer's are sharing the variable "a" and creating a problem like each panel's label showing a value incremented by 4 after every second. Can any body solve this problem..
