在SPGridView中可视化SPmenuField

Question

I have created SPGridView and added one SPMenuField as the first column and some BoundFields . Then I added MenuTemplate to the first column. But there are rectangles with white color border. I want to hide them. How can I do it ?

Here is the code I use:

   SPMenuField colMenu = new SPMenuField();
   colMenu.HeaderText = "Title";
   colMenu.TextFields = "Title";
   colMenu.MenuTemplateId = "TitleListMenu";
   colMenu.NavigateUrlFields = "WebId, ListId, ID";
   colMenu.NavigateUrlFormat = "default.aspx?WebID={0}&ListID={1}&ListItemID={2}";
   colMenu.TokenNameAndValueFields = "Param1=ID";
   colMenu.SortExpression = "Title";

   MenuTemplate typeListMenu = new MenuTemplate();
   typeListMenu.ID = "TitleListMenu";

   // ... //

   Controls.Add(typeListMenu);
   customGridView.Columns.Add(colMenu);
