我正在开发一个应用程序，其中添加了转发器控件，并且在其中添加了Grid View，因为我需要基于从db提取的数据显示单独的网格。因此，数据基于日期进行分组并分成网格。现在，每个网格都附有另一个按钮。如果用户单击，它将向该特定网格视图添加新行。假设用户单击两次添加了两个新行。我面临的问题是从要添加的行中获取值。由于行尚未成为网格的一部分，因此row.count()仅给我计数直到存在的行。因此，任何解决方案都如何获取值。这是代码：
private void CreateExtraFooter(GridView grdview, List<Employee> list, int NoOfFooter_rows)
{
for (int i = 0; i < NoOfFooter_rows; i++)
{
GridViewRow row = new GridViewRow(i, i, DataControlRowType.Footer, DataControlRowState.Normal);
#region Eachrow

此方法将新行添加到网格中，并且根据单击的次数将其添加到网格中。唯一的问题是，当用户在行字段中输入值时，如何获取新添加的行的值。
