我正在使用一个grid view我提供两个选项，
- 如果您在数据库中有数据，它将显示在
edit template， - 如果没有数据
footer template，将 b 显示entering new data。
但是当我尝试第二点时，空白编辑模板也会显示在带有编辑按钮的页脚行上方，请建议我在没有数据时如何隐藏该编辑模板。
我的代码是

在页脚中添加空行的功能：
private void ShowNoResultFound(DataTable source, GridView gv)
{
source.Columns.Add("code_name");
source.Columns.Add("OBSERVATION");
source.Columns.Add("OBS_STATUS");
source.Columns.Add("Flag");
source.Rows.Add(source.NewRow()); // create a new blank row to the DataTable
// Bind the DataTable which contain a blank row to the GridView
gv.DataSource = source;
gv.DataBind();
