推荐答案

捕获keypress事件并检查如果按下Enter键，则读取文本框的当前值，并将此值添加到datagridview的数据源中，然后刷新datagridview

Catch the keypress event and check if the enter key is pressed, read the current value of the textbox and add this value to the datasource of the datagridview and then refresh the datagridview

制作一个DataSet

DataSet textData_DataSet = new DataSet();

在其中添加一个数据表

Add One Data Table in It

DataTable dtLocal = textData_DataSet.Tables["textData_DataTable"];
dtLocal.Columns.Add("txtitem", typeof(string));
dtLocal.Columns.Add("txtqty ", typeof(double));

每次在datagrid中添加数据时都要使Datarow每次在现有数据表"dtLocal"中添加新的原始数据，而每次要添加行时都不要创建新的数据表

Make Datarow each time you want to add data in datagrid add new raw each time in existing datatable "dtLocal" not making new datatable each time you want to add row

DataRow drLocal;
drLocal = dtLocal.NewRow();
drLocal["txtitem "] = txtitem.text.toString();
drLocal["txtqty "] = (double)txtqty.text;

dtLocal.Rows.Add(drLocal);

调用此方法刷新数据网格

Call this method to refresh datagrid

this.RefreshDatagrid(textData_DataSet);

每次添加数据时刷新DataGrid

Refresh DataGrid Each Time You Add Data

Public void RefreshDatagrid(DataSet datasetArg)
{
	yourDatagrid.DataSource = datasetArg.DefaultView;
}
