设定 GridView 内框线的颜色

GridView 控件没有提供属性设定内框线的颜色，不过我们可以设定 GridView 的 Attributes("bordercolor") 来达到这个需求。

以下的范例就是将 GridView 的内框线设为蓝色。

   1:      Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
2:          GridView1.Attributes("bordercolor") = System.Drawing.ColorTranslator.ToHtml(Drawing.Color.Blue)
3:      End Sub

我们也可以扩展 GridView 控件，加入一个 GridLineColor 属性，用来设定 GridView 的内框线颜色。

   1:  Imports System
2:  Imports System.Collections.Generic
3:  Imports System.ComponentModel
4:  Imports System.Text
5:  Imports System.Web
6:  Imports System.Web.UI
7:  Imports System.Web.UI.WebControls
8:  Imports System.Drawing
9:
10:  < _
11:  Description("GridView 控件"), _
12:  ToolboxData("<{0}:TBGridView runat=server></{0}:TBGridView>") _
13:  > _
14:  Public Class TBGridView
15:      Inherits GridView
16:      Private FGridLineColor As Color
17:
18:      ''' <summary>

19:      ''' GridView 网格线颜色。

20:      ''' </summary>

21:      < _
22:      Description("GridView 网格线颜色"), _
23:      TypeConverter(GetType(WebColorConverter)), _
24:      Category("Appearance"), _
25:      DefaultValue(GetType(Color), "")> _
26:      Public Property GridLineColor() As Color
27:          Get
28:              Return FGridLineColor
29:          End Get
30:          Set(ByVal value As Color)
31:              FGridLineColor = value
32:          End Set
33:      End Property
34:
35:      ''' <summary>

36:      ''' 输出客户端检视的 HTML 码。

37:      ''' </summary>

38:      ''' <param name="writer">用来在客户端浏览器上呈现服务器控件内容。</param>

39:      Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
40:          If Me.GridLineColor <> Drawing.Color.Empty Then
41:              Me.Attributes("bordercolor") = System.Drawing.ColorTranslator.ToHtml(Me.GridLineColor)
42:          End If
43:          MyBase.Render(writer)
44:      End Sub
45:  End Class
