嗨
我对我们的问题不是很清楚，但是逻辑是这样的:

Hi
I am not cleared about our question very much but the logic is something like:

protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
   {
       //If Rows > 3 then it will not display selected row (from 1 to 3 rows)
       if (GridView1.Rows.Count > 3)
       {
           if (e.NewSelectedIndex > 2)
           {
               //If Rows > 3 and SelectedIndex > 2 (it started from 0) then it will display selected row (from 4 to n..)
               GridView1.Rows[e.NewSelectedIndex].CssClass = "AllowSelection";
           }
           else
           {
               //If Rows > 3 and SelectedIndex < 2 (it started from 0) then it will not display selected row (0 to 2)
               GridView1.Rows[e.NewSelectedIndex].CssClass = "DisallowedSelection";
           }
       }
       else
       {
           //If Rows < 3 then it will display selected row (0 to 2)
           GridView1.Rows[e.NewSelectedIndex].CssClass = "AllowSelection";
       }
   }
