You can access it by using
HttpContext.Current.Session .

Tried HttpContext.Current.Session ? Are you writing this in any event which fires before session gets initialized ?

Well can you display your if statement so we can see what is happening, there could be a number of reasons.
What event is your code in?
|
|
|
|

This is my code
protected void lnkPrevious_Click(object sender, EventArgs e)
{
if (this.PageNumber ==1)
{
lnkPrevious.Enabled = false;
lnkNext.Enabled = true;
Response.Redirect("pge1.aspx");
}
else
{
this.PageNumber -= 1;
Response.Redirect( "pge"+this.PageNumber.ToString()+".aspx");
}
}

iam having 11 pages.
iam in 7th page.
if i click previous btn it will go to 6th page .thats why i put
this.pagenumber-=1;

What is page1.aspx?
If it is the current page, Then It will be depend upon the design of the page(if you are not not set the enabled property at design time,by default it will be enabled).
So
kathyani wrote: lnkPrevious.Enabled = false;
Disable your link button, but
kathyani wrote: Response.Redirect("pge1.aspx");
will Enable it.
EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.

iam having 1 to 11 link buttons.
if i click 1 button previous button should be disable.
if i move 2 nd button it should be enable.

Try this, First redirect then disable the button.
protected void lnkPrevious_Click(object sender, EventArgs e)
{
if (this.PageNumber ==1)
{
Response.Redirect("pge1.aspx");
lnkPrevious.Enabled = false;
lnkNext.Enabled = true;
}
else
{
this.PageNumber -= 1;
Response.Redirect( "pge"+this.PageNumber.ToString()+".aspx");
}
}
EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.

problem is :
You are calling PageNumber in this line ---> if (this.PageNumber == 1) before you have set the value. So you are getting that error. Set the value first then you must do a get.
To Fix this:
Write a contructor of your class and inside the constructor set the value of _pageNumber = 1 or 0 as per your requirement.
sample code here!!!
public PagerControl()
{
_pageNumber = 1;
}
Thanks,

Hi arindam ..
i didnt get .
plz guide me in code level ..
|
|
|
|
|
i did'nt get.
plz tell me clearly..
|
|
|
|
|
Just copy the code part I have given !!
public PagerControl()
{
_pageNumber = 1;
}
after this line .
public partial class PagerControl : System.Web.UI.UserControl
{
private int _pageNumber;
So that it looks like:
public partial class PagerControl : System.Web.UI.UserControl
{
private int _pageNumber;
public PagerControl()
{
_pageNumber = 1;
}
Thanks,

ITS GIVING A ERROR ,
class,structs,interface method must have a return type.
|
|
|
|
|
it looks like the viewstate page number has not been created yet which is why its showing an object refrerence error as yoiu arent referencing anything!

You are retrieving the PageNumber before setting it.So
kathyani wrote: return int.Parse(ViewState["PageNumber"].ToString());
Will be null.
