Hi
I am trying to use the ajax timer control.
I have got it working in my app so the time is running at real time i.e. updating every second.
The problme is the rest of my app is grinding to a halt because of the timer control.
The timer control sits in the master page but every other page takes a lot longer to load than before
Any ideas?
thanks

Might be your timer control is taking more CPU time than other process.
Its total gyess not sure Unsure | :~

[Edited]
You should always remember that even though partial updates are not as heavy on the server as real postbacks, the server is still contacted, and when using timers, you may get a lot of partial postbacks, which can slow things down. Always use as high intervals as possible, and consider if contacting the server is really necessary or not.

Does the ajax control run the page load code when it refreshes even a small part of the page?

Yes all server side events are going to call for asynchronous post back.

please have look at it

So putting a timer control on a page which has controls which autopostback is not a good idea yeah?
How annoying, I will have to scrap the timer control.
Be good if you could re-load the page without the whole code running

Hi in my image click i am hiding one TD column in my table and assigning another image url to my image...,

Everything working fine...,
But After hide if i click the changed image it have to show the TD column...,Its not working fine....,

How to do that...,

This is my code for hiding the TD column:

function centerimgclick()
{
var ch=document.getElementById('CenterImg');
if(ch.src="Images/LeftHide.jpg")
{
document.getElementById('LeftTD').style.display='none';
document.getElementById("RightTD").style.width='100%';
document.getElementById('CenterImg').src="Images/LeftExpand.jpg";
return;
}
else if(ch.src="Images/LeftExpand.jpg")
{
document.getElementById('LeftTD').style.display='block';
document.getElementById("RightTD").style.width='80%';
document.getElementById('CenterImg').src="Images/LeftHide.jpg";
return;
}
}
and calling this script in my image click like this:

<img id="CenterImg" src="Images/LeftHide.jpg" onclick="javascript:centerimgclick();"/>

Thanks & Regards,

Instead of document.getElementById('LeftTD').style.display='block';

Have you tried:

document.getElementById('LeftTD').style.display='table-cell';

Hope this helps,

problem with session variables

hi all,

I used this site a reference for many thing . I got answers from other,s post itself .Rarely i posted questions

Now i am facing a problem . I were using module variables in application .Now we chnaging to session varibles

I am using an object of a class in each webpage . since i dont want to declare that object in each function i am declaring at the form level

when i was using module variable it was not giving any error
i changed it to session variable . Now it s giving an error

error is pasted below

Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.

so i added EnableSessionState="True" to page directive . then also it is giving error

this is the code that gave the error

Partial Public Class Chart
    Inherits System.Web.UI.Page
     Dim ObjCls As New MVCTM.ClsFetchApply("", Session("country"))
     Dim OraMod As New MVCTM.ModMain(Session("country"))    Dim dt As New DataTable()
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

when i changed the declaration in to form load it is not giving any error

Partial Public Class Chart
    Inherits System.Web.UI.Page
    
    Dim dt As New DataTable()
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 Dim ObjCls As New MVCTM.ClsFetchApply("", Session("country"))
        Dim OraMod As New MVCTM.ModMain(Session("country"))

Can any one suggest me a solution

thanks & regards

No. When the Page object is created it's too early to use Session variables, as it's determined later if the page is sessionless or not.

Despite everything, the person most likely to be fooling you next is yourself.

Can you not say something like:

Dim ObjCls As MVCTM.ClsFetchApply
Dim OraMod As MVCTM.ModMain

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
   ObjCls = New MVCTM.ClsFetchApply("", Session("country"))
   OraMod = New MVCTM.ModMain(Session("country"))

Hi All,

In a .aspx page i run some heavy javascript code that takes 7-10 seconds to be completed,before starting
this processing i display a .gif image,In this image a dot automatically rotates.This image shows the user that
processing is being done and he should wait.Rotation of dot is in-built in this image.
But when javascript code runs,in image this dot stops rotating.

i just know that this happens due to heavy javascript code.
Please provide some solution or some other alternative.

Thank You.

The event for button click on my firstpage.aspx:
session["username"]=TextBox1.Text;
Response.Redirect("~/second.aspx");

second.aspx

page load event:

if((string)Session["username"]==null)
Response.Redirect("~/firstpage.aspx");
else
Response.Write("Welcome");

log out button click event of second.aspx:

Session["username"]=null;
Session.Abandon();
Response.Redirect("~/firstpage.aspx");

Code is working and i am redirected to firstpage.aspx after clicking log out button but when i am clicking back button of browser i can also access second.aspx which i dont want.What should i do to restrict the access of the second page after logging out???

Check whether u can access the controls of secondpage.aspx after logout or u just see the page.

I think if you try to access any control of secondpage.aspx, u'll be redirected to firstpage.aspx and will be asked for username & password.

If you are not already using it, I highly recommend the asp.net login control.
Its very good and allows you to do lots of things such as the above.

Not always. It will always better to use your own custome login control.
