我有两个 dxg:GridControl 控件。一个控件具有复选框列，当用户想要从第一个 dxg:GridControl 中选择一条记录时，用户将单击该记录上的复选框，这样用户将能够选择多条记录。当用户单击 BtnGetSelected_Click 按钮时，我想获取所有选定的数据并显示在第二个 dxg:GridControl 中，而无需从第一个 dxg:GridControl 中删除记录。
Can someone please help me to do this.
My second goal is to enhance this program to drag and drop record from first dxg:GridControl to second dxg:GridControl.
Much appreciate someone hep me to achieve these two.
I have been searching for an answer for more than 4 days now.
Thank you very much.
