DataGrid相邻行有相同内容时对指定列合并和C#可以实现DLL库的动态调用

有时候我们需要,设置gridview的表格线,研究了好久,找了很多资料,终于解决

GridView1.Attributes.Add( " BorderColor " ,  " #0693F5 " );

 

如果如下设置,结果表格边框的颜色变了.

< asp:GridView ID = " GridView1 "  runat = " server "  BorderColor = " red " >
  </ asp:GridView >

到页面看源代码

< table cellspacing = " 0 "   border = " 1 "  id = " GridView1 "  style = " border-color:Red;border-collapse:collapse; " >
   < tr > .

其中BorderColor = " red 解释成了style= " border - color:Red了,但是这并不是我们所要的.我们要的表格线的颜色为红色,而不是表格边框颜色为红色,所以只能在GridView呈现前添加属性

GridView1.Attributes.Add( " BorderColor " ,  " #0693F5 " );
