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.

They may make your job easier, but have you considered their impact on the users of your system? The principal reason why using tables for layout is because it represents a misuse of the TABLE tag. The purpose of the TABLE tag in HTML is to display tabular data. Using tables for layout purposes will make it difficult for partially-sighted or blind people, who rely on screen reading technology, to use your site as the markup will be confusing for them. As a web developer, it is your responsibility to ensure that your site is accessible to all. Making design decisions that discriminate against people is not a good idea.

I have a ASP.Net web application using C#, is there a way for me to get the PC screen resolution? I think I have to use javascript for this, but I don't know the syntax. If I have to use javascript, how do I get the value from the javascript variable into a C# variable? Thanks.

Use the Javascript screen[^] object to obtain the screen resolution. In your Javascript code, store the resolution info in hidden fields set to run server-side, then retrieve the info in your server-side code when you post the page back.

Can you point me to an example of storing the resolution in hidden fields set to run server-side?

I don't have an example to hand. However I suggest you look at the HiddenField control.

Hi
try to accomodate your page at any resolution, this is the best way to persent your pages,
if you have any complicated design,
use screen.availHeight, screen.availWidth,
best way to keep the resolution in the server side,
in the login screen, send this height and width as comma separated values by hidden control.
once you authenticated the page, you will keep some user information in the session,
same time keep this height and width in your session,
Note: if the user resize the screen, server side values can't updated.
