继承GridView控件加入ClickBackGroundColor和ClickFontColor属性，其中ClickBackGroundColor属性是设置单击当前行时的背景色，ClickFontColor是设置单击当前行时的字体颜色．默认单击行不变色，代码如下：
using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace MyLabel
{
public class MyGridView:GridView
{
public MyGridView()
{
}
[Browsable(true)]
[Category("Appearance")]
[Description("设置单击当前行时当前行的背景色")]
public virtual string ClickBackGroundColor
{
get
{
return ViewState["ClickBackGroundColor"]!=null?(string)ViewState["ClickBackGroundColor"]:"";
}
set
{
ViewState["ClickBackGroundColor"] = value;
}
}
[Browsable(true)]
[Category("Appearance")]
[Description("设置单击当前行时当前行的字体背景色")]
public virtual string ClickFontColor
{
get
{
return ViewState["ClickFontColor"] != null ? (string)ViewState["ClickFontColor"] : "";
}
set
{
ViewState["ClickFontColor"] = value;
}
}
protected override void OnRowDataBound(GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowIndex != -1)
{
if (ViewState["ClickBackGroundColor"] != null && ViewState["ClickFontColor"] != null)
{
e.Row.Attributes["onclick"] = "if(window.oldtr!=null){window.oldtr.runtimeStyle.cssText= ' ';}this.runtimeStyle.cssText= 'background-color:" + ViewState["ClickBackGroundColor"].ToString() + ";color:" + ViewState["ClickFontColor"].ToString() + " ';window.oldtr=this ";
}
}
}
base.OnRowDataBound(e);
}
}
}
前台代码如下：
