点击GridView任意位置，选中所在行

1.在GridView中加入ridiobutton控件
<asp:GridView ID="GridView1" runat="server"
                        DataSourceID="ObjectDataSource1" SkinID="common" OnRowDataBound="GridView1_RowDataBound">
                        <Columns>
                            <asp:BoundField DataField="depId" HeaderText="部门编号" SortExpression="depId"/>
                            <asp:BoundField DataField="depName" HeaderText="部门名称" SortExpression="depName"/>
                            <asp:BoundField DataField="principal" HeaderText="负责人" SortExpression="principal"/>
                            <asp:BoundField DataField="depMemo" HeaderText="备注" SortExpression="depMemo" />
                            <asp:TemplateField InsertVisible="False">
                                <ItemTemplate>
                                    <input id='<%#"select_" + DataBinder.Eval(Container, "dataitem.depId")%>' name="select" type="radio" />
                                </ItemTemplate>
                            </asp:TemplateField>
                        </Columns>
                    </asp:GridView>

2.在GridView的RowDataBound事件里写入变色代码
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DataRowView row = (DataRowView)e.Row.DataItem;
            string id = row["depId"].ToString();
            e.Row.Attributes.Add("onclick", "select" + id + "checked=true;");
        } 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "if(this!=prev){c=this.style.backgroundColor;this.style.backgroundColor='#D8F3C6'}");//当鼠标停留时更改背景色
            e.Row.Attributes.Add("onmouseout", "if(this!=prev){this.style.backgroundColor=c}");//当鼠标移开时还原背景色
            e.Row.Attributes["style"] = "Cursor:hand";//设置悬浮鼠标指针形状为"小手"

            //DataRowView row = (DataRowView)e.Row.DataItem;
            //string id = row["depId"].ToString();
            //e.Row.Attributes.Add("onclick", "select_" + e.Row.Cells[0].Text + ".checked=true;");

            e.Row.Attributes.Add("onclick", "select_" + e.Row.Cells[0].Text + ".checked=true;selectx(this)");
        }
    }3.在前台js脚本写控制函数
    <script language="javascript" type="text/javascript" >
    var prev=null;
        function selectx(row)   /**//*改变选中行的颜色还原为选中行的颜色*/
        {
            if(prev!=null)
            {
                prev.style.backgroundColor='#E4F7D8';
            }
            row.style.backgroundColor='#8EC26F';
            prev=row;
            
        }
    </script>
