我数据绑定上去了，现在想修改其某一列的值，不知道怎么弄，大侠们给我说一下用什么方法修改掉datagrid里某一列的值啊??

for(int i = 0; i < dataGridView1.Rows.Count; i++)
dataGridView1.Rows[i].Cells[].Value=

那如果是在绑定之前呢,
table的某一列值变掉:

    ds = searchdate.Searchdoc_certification(DropDownList3.SelectedValue.Trim(),TextBox5.Text.Trim());
                if(ds.Tables[0].Rows.Count != 0)
                {
                    for(i=0;i<ds.Tables[0].Rows.Count;i++)
                    {
                       [i] ds.Tables[0].Rows[9].ToString =inure;出错,赋值号左边必须是变量,属性或索引器
                    }
                }

ds.Tables[0].Rows[9]["列名"]=inure;

非常感谢,这样是编译通过了,可是里面的inure的值根本没有返回到ds里面.
ds = searchdate.Searchdoc_certification(DropDownList3.SelectedValue.Trim(),TextBox5.Text.Trim());
                if(ds.Tables[0].Rows.Count != 0)
                {
                    for(i=0;i<ds.Tables[0].Rows.Count;i++)
                    {
                        ds1=searchdate.SearchProduct_Station_id(ds.Tables[0].Rows[i][2].ToString(),ds.Tables[0].Rows[i][3].ToString());
                        Product_Station_id = int.Parse(ds1.Tables[0].Rows[0][0].ToString());
                        for (j=0;j<ds1.Tables[0].Rows.Count;j++)
                            ts = searchdate.Searchdoc1_productid(Product_Station_id,ds.Tables[0].Rows[i][4].ToString());

                            if (int.Parse(ts.Tables[0].Rows[j][1].ToString())>int.Parse(ts.Tables[0].Rows[j][2].ToString()))
                            {
                                inure = "true";
                                break;

                            }
                            else
                            {
                                inure = "false";
                            }

                        
                        Response.Write("<script>alert('"+inure+"')</script>");

                        
                        ds.Tables[0].Rows[i][9] =inure; True或者False根本没有返回到DS的table里,哪里弄错了啊?帮忙帮我看下.
                           
                           
                    }
                }
               
                DataGrid1.DataSource = ds;
                DataGrid1.DataBind();

ds.DataSet.AcceptChanges();

ds = searchdate.Searchdoc_certification(DropDownList3.SelectedValue.Trim(),TextBox5.Text.Trim());
                if(ds.Tables[0].Rows.Count != 0)
                {
                    for(i=0;i<ds.Tables[0].Rows.Count;i++)
                    {
                        ds1=searchdate.SearchProduct_Station_id(ds.Tables[0].Rows[i][2].ToString(),ds.Tables[0].Rows[i][3].ToString());
                        Product_Station_id = int.Parse(ds1.Tables[0].Rows[0][0].ToString());
                        for (j=0;j<ds1.Tables[0].Rows.Count;j++)
                            ts = searchdate.Searchdoc1_productid(Product_Station_id,ds.Tables[0].Rows[i][4].ToString());

                            if (int.Parse(ts.Tables[0].Rows[j][1].ToString())>int.Parse(ts.Tables[0].Rows[j][2].ToString()))
                            {
                                inure = "true";
                                break;

                            }
                            else
                            {
                                inure = "false";
                            }

                        
                        Response.Write("<script>alert('"+inure+"')</script>");

                        
                        ds.Tables[0].Rows[i][9] =inure;

                           
                           
                    }
                }
                ds.AcceptChanges(); 填上去了,似乎还是返回原来的值,没什么用啊!!!
               
                DataGrid1.DataSource = ds;
                DataGrid1.DataBind();

试试看这样呢。。。。
(（Textbox）this.GridView1.Rows[e.RowIndex].Cell[0].Control()).Text.ToString();
