为什么会更新不起？

[tanshiyang82]

DataRow dr=this.myDataset1.Tables[TABLE_NAME].NewRow();
dr[COL_CLASS_NAME]=this.textBox1.Text; //设置字段内容
dr[COL_GRADE]=this.comboBox1.SelectedValue;//设置字段内容
dr.EndEdit();
this.myDataset1.Tables[TABLE_NAME].Rows.Add(dr);

this.da_Class.Update(ds_myDataset1,TABLE_NAME);
ds_myDataset1.AcceptChanges();

[Night_Elf]

ds_myDataset1.AcceptChanges();
在更新之前

在操作数据前加一个
OleDbCommandBuilder cb = new OleDbCommandBuilder(youOleDbDataAdapter);
