session variable will be reseted , once you close the browser window,

if you want to keep the values until reset the server,

use Application variables or cache variables.

also - if the browser disabled the cookies, session variables will reseted every postback of the page.

Hi all
iam printing a grid view by using the following java script. I want to use paging however this JS is only printing the first page. Any ideas on how can print all and use paging.

<script type="text/javascript"><br />
    function PrintReport()<br />
    {<br />
        var m = document.getElementById('menu');<br />
        m.style.display='none';<br />
        window.print();<br />
        m.style.display='block';        <br />
    }<br />
</script>

This is not printing the Gridview alone. it's printing the whole page. It will print whole contents of page. So if your grid view is showing only first page, you will get only that in print out. To get a complete print, you should show all data on the page.

Thanks in advance

Singleton ?[^]. You should be careful to make your instance thread safe. Because web applications are multi-threaded.

What is Gridbiew's data source type ? I assume it's a DataTable. So you could do the following.

DataTable dt = (DataTable)gv.DataSource;
int count = 0;
foreach (GridViewRow gv in gv1.Rows)
{
    CheckBox cb = (CheckBox)gv.FindControl("chkSelect");
    if (cb.Checked)
    {
        DataRow row = dt.Rows[count];
        //Take necessary values from row       
        count++;
    }
}

Gridbiew's data source is datatable as you said.
I want to export the selected row to a word document.If i have selected 10 rows how can i get that rows and assign to another datatable.

Create a new DataTable instance and add this rows to there like DataTable.Rows.Add(row)

DataTable.Rows.Add(row) cannot be used since we cannot add an existing row to another datatable.
i have used
dt1 = dt.Clone()
dt1.ImportRow(row)
but it there i'll get only the last row.I want all the selected row.Please help

is there any private key or unique table's field in the record?
if there is any unique field in data that you bind to gridview than assign it to hiddenfield control in your gridview (like you put checkbox control in your gridview).

Arraylist arrID = new arraylist();
foreach (GridViewRow gv in gv1.Rows)
{
  CheckBox cb = (CheckBox)gv.FindControl("chkSelect");
  if (cb.Checked)
  {
    HiddenField hf = (HiddenField)gv.FindControl("HiddenFieldNames");
    arrID.add(hf.value);
  }
}

DataTable dbTable = QueryBackToDB(arrID);

then you can query arrID to your database then ..... walah...there's your selected record (dbTable in code example, above).

this will query back to your database again, but at least, the data will be reliable.

you can always try to get the index where your checkbox is checked
try to loop with [for], and don't with [for each] so you can get the index easily. then you match with the index from your search with the index in datatable that you bind to gridview.

i hope this can help you.
