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.

Isn't there another way to print only the grid?
|

Copy grid to a blank page and print from there

Hi,
I want to use one Excel object in my web application, i.e with only one EXCEL process and we can use that process.
I am using
Excel.Application objExcelApp = new Excel.Application();

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

This is a new requirement to export selected rows to word document.
i have done this much
int count = 0;
foreach (GridViewRow gv in gv1.Rows)
{
CheckBox cb = (CheckBox)gv.FindControl("chkSelect");
if (cb.Checked)

Thanks

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];
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.

I have already done what you have told,i am already having all the records in datable so need to query it again from database.
here is what i have done
DataTable dt = searchDatatable();
DataTable dt1 = new DataTable();
int count = 0;
DataRow row=null;
foreach (GridViewRow gv in gv1.Rows)
{
CheckBox cb = (CheckBox)gv.FindControl("chkSelect");
if (cb.Checked)
{
row = dt.Rows[count];
//Take necessary values from row
dt1 = dt.Clone();
count++;
foreach (DataRow dr in dt.Rows)
{
dt1.ImportRow(dr);
}
}
}
this will return only the last row,i want all the rows which r checked.I have spend a long time for this and its very urgent.
Please help

hello Anupbala,
i'm sorry that i can't reply ASAP due yesterday i have employee meeting.
have you find the solution?
if not, you didn't do exactly what i have told you, if i look in to your code.
you need to do the process individually. don't grouping them in one looping process.
this what i mean :
Arraylist arrDataToQuery = GetAllTheIDWhenCheckboxIsChecked();
Datatable dtQueryResult = QueryResult(arrDataToQuery);
gvDontCareItsName.DataSource = dtQueryResult;
gvDontCareItsName.Databind();
hope this help, if u're not dead with this problem  , or maybe you have won...

Hi Boku,
Thanks for your response,i have found a solution for this in the other way as i said.
i am already having the entire records in a datatable,so there is no need to query it back again.
here is my solution
DataTable dt = GetAllRows();
DataTable dt1 = dt.Clone();
int count = 0;
DataRow row = null;
foreach (GridViewRow gv in gv1.Rows)
{
CheckBox cb = (CheckBox)gv.FindControl("chkSelect");
if (cb.Checked)
{
row = dt.Rows[gv.RowIndex];
dt1.ImportRow(row);
count++;
}
}
dt1.AcceptChanges();
I am posting it as it comes helpful for somebody else

Using tables are nowadays not recommended. Because tables uses nested tags which makes the loading time more that using SPANs & DIVs. The file size also more than the pages which you divs & spans for layouts.
But me too used to use tables from the beginning itself and not able to switch to divs & spans. But I recommend the beginners to use DIVs & SPANs rather than TABLEs.

True. But most of the programmers including me are bad in designing. Tables are easy way to implement.
