Have you checked that your table is not empty?

I suggest you put a break-point on the first line of the 'display method, and then single-step, using F11, through the code, observing the value of each variable. That should give you some insight into what is happening ... or not happening.

Change your Display() Method by this way:

C#

private void display(DataTable tbl)
{
    txtempid.Text = tbl.Rows[0][1].ToString();
    txtname.Text = tbl.Rows[0][2].ToString();
    txtsurname.Text = tbl.Rows[0][3].ToString();
    txtfathername.Text = tbl.Rows[0][4].ToString();
    dtdob.Text = tbl.Rows[0][5].ToString();
    cbgender.Text = tbl.Rows[0][6].ToString();
    cbcity.Text = tbl.Rows[0][7].ToString();
    txtcontactno.Text = tbl.Rows[0][8].ToString();
    dtdoj.Text = tbl.Rows[0][9].ToString();
    txtdept.Text = tbl.Rows[0][10].ToString();
    txtdesig.Text = tbl.Rows[0][11].ToString();
    txtqualification.Text = tbl.Rows[0][12].ToString();
    rtaddress.Text = tbl.Rows[0][13].ToString();
    rtremarks.Text = tbl.Rows[0][14].ToString();
}

Then in main method:

C#

display(tbl);
