GridView1.DataKeyNames = new string[] { "id" };
GridView1.DataBind();
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
bind();
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string id = GridView1.DataKeys[e.RowIndex].Value.ToString();
string sSql = "delete News where id=" + id;
SQL s = new SQL();
bool result = s.SqlResults(sSql);
if (result == true)
{
Page.RegisterStartupScript("alert", "<script>alert('删除成功！');</script>");
}
else
{
Page.RegisterStartupScript("alert", "<script>alert('删除失败！');</script>");
}
bind();
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
string id=GridView1.DataKeys[e.NewEditIndex].Value.ToString();
Response.Redirect("News_checkdate.aspx?id=" + id);
}
}
4.5信息审核设计及实现
为了保证发布信息的安全性、完整性、可靠性，系统中设计了信息审核的模块，对信息的标题、内容进行审核，审核通过后才能对信息进行发布，工浏览者浏览、阅读以及评论。如图4.7所示。
图4.7 信息审核页面
点击“审核”进入审核界面，审核信息标题、内容后点击审核通过即可，如图4.8所示。
图4.8信息审核页面
此功能实现的关键代码如下：
public partial class Manage_News_checkdate : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
TextBox3.Text = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
bind();
}
}
private void bind()
{
string sSql = "select * from News where id="+Request["id"].ToString();
SQL s = new SQL();
DataView dv = s.DSSearch(sSql).Tables[0].DefaultView;
TextBox1.Text = dv[0].Row["Title"].ToString();
TextBox2.Text = dv[0].Row["Contents"].ToString();
}
protected void Button1_Click(object sender, EventArgs e)
