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 " );
