This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
And that makes no sense to me at all.
Perhaps an example of what you are trying to achieve would help?

i want my checked status of checkbox persist even after loading it again...

Peter Leow 28-Mar-15 5:50am

You mean to keep the checked status after postback?

Deeepakk 28-Mar-15 5:59am

yeah, i want my checked status to be constant.

Peter Leow 28-Mar-15 6:04am

Put your initialization code for GridView in a if block that check for not postback, like this:
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
// your gridview binding code here
}
}

No dude, its not working..
i am checking the rows after loading page, and again if i load from scratch the checkbox should contain previous status that is checked.

show code.

if (!this.IsPostBack)
{

int res = 0;
int count = 0;
string query = "";
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkRow = (row.Cells[0].FindControl("checked") as CheckBox);
if (chkRow.Checked == true)
{

query = "Update Employee set shortlist='Y' where FirstName='" + row.Cells[1].Text + "' and lastname='" + row.Cells[2].Text + "' and email='" + row.Cells[12].Text + "'";

}
else
{
query = "Update Employee set shortlist='N' where FirstName='" + row.Cells[1].Text + "' and lastname='" + row.Cells[2].Text + "' and email='" + row.Cells[12].Text + "'";

}
SqlCommand cmd = new SqlCommand(query, cn);
cn.Open();
res = Convert.ToInt32(cmd.ExecuteNonQuery());
cn.Close();
count += res;

}

}

}

this is page load function

Do you understand the meaning of "IsPostBack"?

Deeepakk 28-Mar-15 7:14am

yes, sending information from client to server, then server process all those contents and returns back to the client.

Peter Leow 28-Mar-15 7:23am

That code that you have shown seems to belong to isPostBack rather than !isPostBack

You can use temp file. Like xml

OriginalGriff 28-Mar-15 6:20am

You do realize that this is web based, don't you?
You don't use "temporary files" in web based solutions because they are always multiuser...

amagitech 28-Mar-15 7:35am

Sorry. I think it's windows form. So I am wondering that. Can we use database for this case.

OriginalGriff 28-Mar-15 7:48am

Again, probably not a good idea - you'd have to store it against each user separately.
A better idea is Session, or Cookies depending on how long you want to store the values - but Peter seems to be helping him ATM, so I'll not jump in.
