第一个问题免不了要遍历，这个pb的datawindow就不错
第二个问题嘛在www.chinaspx.com上面有篇文章，可以参考，去找找，肯定有，我只记得在.net转载文章那个区域

datagrid 其实是内嵌的textbox可以对其设置显示的样式，参考代码：
private void SetDataGrid(string tablename)
{
NetExam.Interfaces.EntityDefinition.ExamLibrary ex=EntityManager.CreateObject(typeof(NetExam.Interfaces.EntityDefinition.ExamLibrary)) as NetExam.Interfaces.EntityDefinition.ExamLibrary;

ex.EntityData.Tables[0].Columns.Remove("HChoiceA");
ex.EntityData.Tables[0].Columns.Remove("HChoiceB");
ex.EntityData.Tables[0].Columns.Remove("HChoiceC");
ex.EntityData.Tables[0].Columns.Remove("HChoiceD");
ex.EntityData.Tables[0].Columns.Remove("HAnalysis");
//this.dataGrid1.DataSource=ex.EntityData.Tables[0];//自动的模式化了     DataGridTableStyle dataGridTableStyle = new DataGridTableStyle();

第一个问题有人说了，第二个问题你用 CurrencyManager 类试一下，只要把影响滚动条的事件都写上一个CurrencyManager.Position = 0;试试
