GridView自带的分页功能实现：
要实现GrdView分页的功能
操作如下：
1、更改GrdView控件的AllowPaging属性为true。
2、更改GrdView控件的PageSize属性为 任意数值（默认为10）
3、更改GrdView控件的PageSetting->Mode为Numeric等（默认为Numeric）该属性为分页样式。
GridView属性设置好了，从页面上也能看到分页样式。
现在开始实现分页的功能：
1、在<<asp:GridView ID=......>后添加，OnPageIndexChanging="GridView1_PageIndexChanging"
2、在对应的aspx.cs中添加：
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
InitPage(); //重新绑定GridView数据的函数
}
3、
GridView1.PageIndex = e.NewPageIndex;
完了之后再重新绑定一下GridView。
GridView添加CheckBox列实现全选/全部取消功能
首先GridView编辑模版，在模板上添加CheckBox控件，之后将新添加列字段转换为TemplateFiled
后台代码：
public partial class Default5 : System.Web.UI.Page
{
SqlConnection sqlcon;
string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind();
}
}
protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
if (CheckBox2.Checked == true)
{
cbox.Checked = true;
}
else
{
cbox.Checked = false;
}
}
}
protected void Button2_Click(object sender, EventArgs e)
{
sqlcon = new SqlConnection(strCon);
SqlCommand sqlcom;
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
if (cbox.Checked == true)
{
string sqlstr = "delete from 飞狐工作室 where 身份证号码='" + GridView1.DataKeys[i].Value + "'";
sqlcom = new SqlCommand(sqlstr, sqlcon);
sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
}
}
bind();
}
protected void Button1_Click(object sender, EventArgs e)
{
CheckBox2.Checked = false;
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
cbox.Checked = false;
}
}
public void bind()
{
string sqlstr = "select top 5 * from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "tb_Member");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "身份证号码" };
GridView1.DataBind();
sqlcon.Close();
}
}
