Kindly give me solution to insert data into database without generating another textbox on btnSubmit click.

推荐答案
Try this:
Try this:
protected void btnSubmit_Click(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{
Decimal Space = Convert.ToDecimal(((TextBox)row.FindControl("txtSpace")).Text);
string GMName = ((Label)row.FindControl("Label1")).Text;
string Comments = ((TextBox)row.FindControl("txtComments")).Text;
string Remarks = ((TextBox)row.FindControl("txtRemarks")).Text;
//here you can add a condition when should insert your data into the database
if(GMName != string.Empty)
{
EmployeeDataAccessLayer.InsertEmployee(GMName, Space, Comments, Remarks);
}
}
BindGridViewData();
}
