我已经将dataset 中的表绑定到DataGrid中了
     代码如下~~，但出现错误~出现错误如下：

请各位高手帮我一下呀，谢谢`~
        SqlConnection cn=new SqlConnection();
            cn.ConnectionString="server=(local);Trusted_Connection=yes;database=BlueHill";
            SqlDataAdapter da=new SqlDataAdapter("select * from viwwinLeaveList",cn);
            DataSet ds=new DataSet();
            da.Fill(ds,"viwleave");
            this.dataGrid1.DataSource=ds;
            this.dataGrid1.DataMember="viwleave";

              int a=this.dataGrid1.CurrentCell.RowNumber   ;
              ds.Tables["viwleave"].Rows[a].Delete();
              da.Update(ds,"viwleave");

我也好象遇到过这钟情况

 但是我都没删除行啊`

   等我回去想下是怎么弄好的``

private void toolStripButton5_Click(object sender, EventArgs e)
        {

            String MySQLConnectionString = Properties.Resources.ConnString;


            SqlConnection MyConnection = new SqlConnection(MySQLConnectionString);
            MyConnection.Open();


            
            //总行不少１
            if (this.dataGridView1.SelectedRows.Count > 0)
            {
                //删除记录
                string b ="";

                for (int i = 0; i < this.dataGridView1.SelectedRows.Count;i++ )
                {
                    //删除行下标=当前行－１;
                    int a = this.dataGridView1.CurrentRow.Index - i;

                    //删除

                    SqlCommand MyCommand = MyConnection.CreateCommand();
                    String MySQL = "delete from 酒店房间 where 房号='"+this.dataGridView1[0,a].Value.ToString()+"'";
                     = MySQL;
                    MyCommand.ExecuteNonQuery();


                }

我的方法:
        private void dataGridView2_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
            int row = this.dataGridView2.CurrentRow.Index;
            dataGridView2.Rows[row].Selected = true;

            try
            {
                if (MessageBox.Show("真的要删除序号为" +this.dataGridView2.SelectedRows[0].Cells[0].Value.ToString() + "这个的刀模资料吗?", "提示框", MessageBoxButtons.YesNo, MessageBoxIcon.Information) == DialogResult.Yes)
                {
                    string directory1 = Directory.GetCurrentDirectory() + "\\aa.ini";
                    IniFile db1 = new IniFile(directory1);
                    SqlConnection conn1 = db1.GetDBConn();
                    conn1.Open();
                    SqlCommand cm1 = new SqlCommand("sheji_taomoyinshan", conn1);
                     = CommandType.StoredProcedure;
                    cm1.Parameters.Add("@hao", SqlDbType.VarChar);
                    cm1.Parameters["@hao"].Value = this.dataGridView2.SelectedRows[0].Cells[0].Value.ToString();

                    cm1.ExecuteNonQuery();
                    conn1.Close();
                    toolStripButton1.PerformClick();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

都不能很好的解决根本的问题`~~哎~~

DataSet 里有个属性 能获得你选中的行  返回一个object数组
再用你里面的da.insertCommand 的删除语句 应该没问题

支持一下,

我用的是dataGridView，而不是datagrid，我的方法是这样，希望对你有帮助.
String str = this.dataGridView1.SelectedCells[0].Value.ToString();
            string ste = this.dataGridView1.SelectedCells[3].Value.ToString();
            DialogResult i = MessageBox.Show("你确定要删除网吧名称为:"+ste+"吗?", "删除确定", MessageBoxButtons.YesNo);
            if (i == DialogResult.Yes)
            {
                if ((str != "")&(ste!=""))
                {
                    try
                    {
                        string Afile = "provider=Microsoft.jet.OLEDB.4.0;Data Source=D:\\mysqlserver\\dgmk.mdb";
                        OleDbConnection AconnStr = new OleDbConnection(Afile);
                        OleDbCommand Icmd = new OleDbCommand("Delete from client where 网吧名称='" + ste + "' and 编号=" + Convert.ToInt32(str) + "", AconnStr);
                        AconnStr.Open();
                        Icmd.ExecuteNonQuery();
                        AconnStr.Close();
                        label4.Text = "";
                        toolStripStatusLabel5.Text = "删除网吧名称为:" + ste + " 成功";

谢谢名们了~~又长了不少知识

删除当前选定的行：
int a;
a = this.dataGridView1.CurrentRow.Index;
dataGridView1.BindingContext[dataGridView1.DataSource, dataGridView1.DataMember].RemoveAt(a);
 tbl1TableAdapter.Update(db1DataSet);
db1DataSet.AcceptChanges();
