删除数据表aspx.net中的行

Question

这里我试图删除数据行Table.I想要删除单击索引中的值等于0的行。我尝试但删除所有数据Table.Solution？

   protected void btnTest_Click(object sender, EventArgs e)
    {

        DataTable dtCurrentTable = (DataTable)ViewState["Markici"];

        decimal noofcount = Convert.ToInt32(count); 

            var clickedRow = ((Button)sender).NamingContainer as GridViewRow;
            var clickedIndex = clickedRow.RowIndex;

            decimal old = dtCurrentTable.Rows[clickedIndex].Field<decimal>("Kolicina");
            //int oldValue = int.Parse(old); // in case that you don't know
            decimal newValue = old - 1; // just an example
            dtCurrentTable.Rows[clickedIndex].SetField("Kolicina", newValue.ToString());

      ////Here i'm trying to delete row of clicked button.
            if (old == 0)
            {
                for (int i = 0; i <= dtCurrentTable.Rows.Count; i++)
                {
                    dtCurrentTable.Rows[clickedIndex].Delete();

                    dtCurrentTable.AcceptChanges();
                    GridView2.DataSource = dtCurrentTable;
                    GridView2.DataBind();        
                }



            }
            //dtCurrentTable.Rows[clickedIndex]["Kolicina"] == "0";

            GridView2.DataSource = dtCurrentTable;
            GridView2.DataBind();                     

    }

为什么你甚至会循环？

 if (old == 0)
{
    dtCurrentTable.Rows[clickedIndex].Delete();
    dtCurrentTable.AcceptChanges();
}
