i think you are binding GridView at Page_Load event outside of IsPostBack put you binding code in IsPostBack check it'll work.

//bellow code i am executing sir but it is not reading textbox value but it is reading label values sir like fee_type what may be the problem sir...

protected void btnPayFee_Click(object sender, EventArgs e)
{
for (int i = 0; i < gridviewCandidateDetails.Rows.Count; i++)
{
Label Fee_type = (Label)gridviewCandidateDetails.Rows[i].FindControl("lblFee_Type");
TextBox txtamount = (TextBox)gridviewCandidateDetails.Rows[i].FindControl("txtAmount");
}
}

you are getting lable value because you are binding lable value from DB but in textbox you putting text at runtime that's why you are getting label value.
at which event you are binding Gridview let show me Page_Load code?
