Ya,I'm really sorry, It wont work. Frown | :(

Try this in your page load

if(this.PageNumber ==1)
lnkPrevious.Enabled = false;
else
lnkPrevious.Enabled = true;

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,

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;
    }
    // class continues  as it is in you code
    // ........

Thanks,

ITS GIVING A ERROR ,
class,structs,interface method must have a return type.

You are retrieving the PageNumber before setting it.So

kathyani wrote:

Will be null.

Sherin Iranimose7-Jul-08 1:28

Why can't you set the pagenumber property at the design time itself(for the user control).I mean In the 11 pages.

Add the following code to your user control Page Load, Before 'if'.

<br />
if(ViewState["PageNumber"]==null)<br />
ViewState["PageNumber"]="1";//default page<br />
