Hi,

Try this

if (e.KeyChar == 13)//enter key
{
DataRow dr = dt.NewRow();
dt.Rows.Add(dr);
DGV.CurrentRowIndex = dt.Rows.Count - 1;
}

if(e.KeyChar == 13)
{
DataTable dtg = (DataTable) DataGrid1.DataSource;
DataRow dr = dtg.NewRow();
dr["Item_ID"]="ItemID";
dr["Item_Name"]="Item Name";
dr["Item_Desc"]="Item Description";
dr["Item_Amount"]="

15.65"; dtg.Rows.Add(dr); DataGrid1.DataSource = dtg; 它将适用于Windows. 如果在ASP中使用DataGrid，则必须将DataTable保留在Session中: DataTable dtg = new DataTable(); 如果(Session ["SampleDataTable"] == null) { DataColumn dc; dc = new DataColumn("Item_ID"，System.Type.GetType("System.String")); dtg.Columns.Add(dc); dc = new DataColumn("Item_Name"，System.Type.GetType("System.String")); dtg.Columns.Add(dc); dc = new DataColumn("Item_Desc"，System.Type.GetType("System.String")); dtg.Columns.Add(dc); dc =新的DataColumn("Item_Amount"，System.Type.GetType("System.String"))); dtg.Columns.Add(dc); } else {dtg =(DataTable)Session ["SampleDataTable"];} DataRow dr = dtg.NewRow(); dr ["Item_ID"] ="ItemID"; dr ["Item_Name"] =商品名称"; dr ["Item_Desc"] =项目说明"; dr ["Item_Amount"] ="

15.65"; dtg.Rows.Add(dr); DataGrid1.DataSource = dtg; It will work for windows. If you use DataGrid in ASP then you will have to keep DataTable in Session: DataTable dtg = new DataTable(); if (Session["SampleDataTable"]==null) { DataColumn dc; dc = new DataColumn("Item_ID",System.Type.GetType("System.String")); dtg.Columns.Add(dc); dc = new DataColumn("Item_Name",System.Type.GetType("System.String")); dtg.Columns.Add(dc); dc = new DataColumn("Item_Desc",System.Type.GetType("System.String")); dtg.Columns.Add(dc); dc = new DataColumn("Item_Amount",System.Type.GetType("System.String")); dtg.Columns.Add(dc); } else {dtg = (DataTable) Session["SampleDataTable"];} DataRow dr = dtg.NewRow(); dr["Item_ID"]="ItemID"; dr["Item_Name"]="Item Name"; dr["Item_Desc"]="Item Description"; dr["Item_Amount"]="
