// objPds.CurrentPageIndex = CurrentPage - 1;

Code:

public partial class ConfigurationTool_EditPackage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        //if (!string.IsNullOrEmpty(Request.Form["MemberID"]))
        //{

            PackageList dd = PackageListBL.GetExtraInfo(121);

            if (dd != null)
            {

                PagedDataSource objPds = new  PagedDataSource();
                objPds.DataSource = dd;
                objPds.AllowPaging = true;
                objPds.PageSize = 5;
               // objPds.CurrentPageIndex = CurrentPage - 1;
                rptExtraInfo.DataSource = objPds;
                rptExtraInfo.DataBind();
                
            }
            else
            {


                rptExtraInfo.DataBind();
            }
        }
    //}
    public int CurrentPage
    {
        get
        {
            // look for current page in ViewState
            object o = this.ViewState["_CurrentPage"];
            if (o == null)
                return 0; // default page index of 0
            else
                return (int)o;
        }

        set
        {
            this.ViewState["_CurrentPage"] = value;
        }
    } 
}

Perhaps your CurrentPage is finding nothing in ViewState and returning 0.

Then the CurrentPageIndex would be set to 0 - 1 = -1 which would throw an error.

guddu · #23 January 21st, 2009, 03:33 PM

but i think ViewState["_CurrentPage"] is default page level property.so what to do for this?

guddu · #24 January 21st, 2009, 03:39 PM

i think this

Code:

objPds.CurrentPageIndex = CurrentPage - 1;

should be

Code:

objPds.CurrentPageIndex = CurrentPage;

hi
Thank u so much RR about your help so far.now my paging stuff with repeater is fine now problem is to retaim values of page.
as your know at each page i have form control likes text box ,dropdown .so when user filled all these values at first page and after clicking next go to next page and filled data their also and agian back to previous page the data at this page being lost.

how to retain these values.

richyrich · #26 January 22nd, 2009, 07:27 AM

Could you save the values in a session when it moves to the next page and then retrieve them from the session when it moves back?

guddu · #27 January 22nd, 2009, 07:35 AM

some sort of example would be appreciated about session.

any other way if not willing to use session.

richyrich · #28 January 22nd, 2009, 07:49 AM

To add items to a session variable, use something like:-

Code:

HttpContext.Current.Session.Contents.Add("varName",varValue)

And to retrieve:-

Code:

Dim myValue as String = HttpContext.Current.Session.Contents.Item("varName")

I believe you can manually add items to the viewstate to keep their values, although I've not done this before....I guess you could also save the details in a database...

Maybe someone else might have a better solution...

guddu · #29 January 22nd, 2009, 08:00 AM

once data filling has done in pages then user will submit .after submit i will save that data into database.

but problem is i m using paging so during page navigation i m not able to retain values.

still i m not clear with your example of session??

richyrich · #30 January 22nd, 2009, 08:03 AM

Oh...I see what you mean now....

Hmmm...not sure...I've not used paging before...Will have to have a think about that...
