For Your issue
For template items in gridview, once you did databind then you should assign the values through loop.
gvEmp.DataSource = dtEmployee;
for (int i = 0; i < dtEmployee.Rows.Count; i++)
for (int j = 1; j < dtEmployee.Columns.Count; j++)
if (j == 1 || j == 2 || j == 3)
((TextBox)(gvEmp.Rows[i].Cells[j].Controls)).Text = dtEmployee.Rows[i][j].ToString();
so change the code based on your need
