推荐答案

在DataGrid中添加空行简单e为绑定到此Datagrid的Collection添加一个值。



例如，



如果你有将DataTable绑定到DataGrid，然后在To DataTable中添加新行将自动在Datagrid中添加新的空行。

To Add empty Row in DataGrid simple add one value to the Collection bound to this Datagrid.

for Example,

If you have bound a DataTable to your DataGrid then adding new Row in To DataTable will Automatically add new Empty Row in Datagrid.
