1.GridView无代码分页排序

效果图:

1.AllowSorting设为True,aspx代码中是AllowSorting="True";

2.默认1页10条,如果要修改每页条数,修改PageSize即可,在aspx代码中是PageSize="12"。

3.默认的是单向排序的,右击GridView弹出“属性”,选择AllowSorting为True即可。

2.GridView选中,编辑,取消,删除

效果图:

后台代码:

你可以使用sqlhelper,本文没用。

代码如下:

usingSystem;

usingSystem.Data;

usingSystem.Configuration;

usingSystem.Web;

usingSystem.Web.Security;

usingSystem.Web.UI;

usingSystem.Web.UI.WebControls;

usingSystem.Web.UI.WebControls.WebParts;

usingSystem.Web.UI.HtmlControls;

usingSystem.Data.SqlClient;

publicpartialclass_Default:

System.Web.UI.Page

{

//清清月儿 

   SqlConnectionsqlcon;

   SqlCommandsqlcom;

   stringstrCon="DataSource=(local);Database=数据库名;Uid=帐号;Pwd=密码";

   protectedvoidPage_Load(objectsender,EventArgse)

   {

       if(!

IsPostBack)

       {

           bind();

       }

   }

   protectedvoidGridView1_RowEditing(objectsender,GridViewEditEventArgse)

   {

       GridView1.EditIndex=e.NewEditIndex;

       bind();

   }

//删除

   protectedvoidGridView1_RowDeleting(objectsender,GridViewDeleteEventArgse)

   {

       stringsqlstr="deletefrom 表whereid='"+GridView1.DataKeys[e.RowIndex].Value.ToString()+"'";

       sqlcon=newSqlConnection(strCon);

       sqlcom=newSqlCommand(sqlstr,sqlcon);

       sqlcon.Open();

       sqlcom.ExecuteNonQuery();

       sqlcon.Close();

       bind();

   }

//更新

   protectedvoidGridView1_RowUpdating(objectsender,GridViewUpdateEventArgse)

   {

       sqlcon=newSqlConnection(strCon);

       stringsqlstr="update表set字段1='"

           +((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim()+"',字段2='"

           +((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim()+"',字段3='"

           +((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim()+"'whereid='"

           +GridView1.DataKeys[e.RowIndex].Value.ToString()+"'";

       sqlcom=newSqlCommand(sqlstr,sqlcon);

       sqlcon.Open();

       sqlcom.ExecuteNonQuery();

       sqlcon.Close();

       GridView1.EditIndex=-1;

       bind();

   }

//取消

   protectedvoidGridView1_RowCancelingEdit(objectsender,GridViewCancelEditEventArgse)

   {

       GridView1.EditIndex=-1;

       bind();

   }

//绑定

   publicvoidbind()

   {

       stringsqlstr="select*from表";

       sqlcon=newSqlConnection(strCon);

       SqlDataAdaptermyda=newSqlDataAdapter(sqlstr,sqlcon);

       DataSetmyds=newDataSet();

       sqlcon.Open();

       myda.Fill(myds,"表");

       GridView1.DataSource=myds;

       GridView1.DataKeyNames=newstring[]{"id"};//主键

       GridView1.DataBind();

       sqlcon.Close();

   }

}

前台主要代码:

                           ......

GridViewID="GridView1"runat="server"AutoGenerateColumns="False"CellPadding="4"

                       ForeColor="#333333"GridLines="None"OnRowDeleting="GridView1_RowDeleting"OnRowEditing="GridView1_RowEditing"

                       OnRowUpdating="GridView1_RowUpdating"OnRowCancelingEdit="GridView1_RowCancelingEdit">

                       

                       

                           

BoundFieldDataField="身份证号码"HeaderText="用户ID"ReadOnly="True"/>

                           

BoundFieldDataField="姓名"HeaderText="用户姓名"/>

                           

BoundFieldDataField="员工性别"HeaderText="性别"/>

                           

BoundFieldDataField="家庭住址"HeaderText="家庭住址"/>

                           

CommandFieldHeaderText="选择"ShowSelectButton="True"/>

                           

CommandFieldHeaderText="编辑"ShowEditButton="True"/>

                           

CommandFieldHeaderText="删除"ShowDeleteButton="True"/>

3.GridView正反双向排序

效果图:

点姓名各2次的排序,点其他也一样可以。

后台代码:

usingSystem;

usingSystem.Data;

usingSystem.Configuration;

usingSystem.Collections;

usingSystem.Web;

usingSystem.Web.Security;

usingSystem.Web.UI;

usingSystem.Web.UI.WebControls;

usingSystem.Web.UI.WebControls.WebParts;

usingSystem.Web.UI.HtmlControls;

usingSystem.Data.SqlClient;

publicpartialclassDefault3:

System.Web.UI.Page

{

//清清月儿的博客 

   SqlConnectionsqlcon;

   stringstrCon="DataSource=(local);Database=北风贸易;Uid=sa;Pwd=";

   protectedvoidPage_Load(objectsender,EventArgse)

   {

       if(!

IsPostBack)

       {

           ViewState["SortOrder"]="身份证号码";

           ViewState["OrderDire"]="ASC";

           bind();

       }

   }

   protectedvoidGridView1_Sorting(objectsender,GridViewSortEventArgse)

   {

       stringsPage=e.SortExpression;

       if(ViewState["SortOrder"].ToString()==sPage)

       {

           if(ViewState["OrderDire"].ToString()=="Desc")

               ViewState["OrderDire"]="ASC";

           else

               ViewState["OrderDire"]="Desc";

       }

       else

       {

           ViewState["SortOrder"]=e.SortExpression;

       }

       bind();

   }

   publicvoidbind()

   {

       

       stringsqlstr="selecttop5*from飞狐工作室";

       sqlcon=newSqlConnection(strCon);

       SqlDataAdaptermyda=newSqlDataAdapter(sqlstr,sqlcon);

       DataSetmyds=newDataSet();

       sqlcon.Open();

       myda.Fill(myds,"飞狐工作室");

       DataViewview=myds.Tables["飞狐工作室"].DefaultView;

       stringsort=(string)ViewState["SortOrder"]+""+(string)ViewState["OrderDire"];

       view.Sort=sort;

       GridView1.DataSource=view;

       GridView1.DataBind();

       sqlcon.Close();

   }

}

前台主要代码:

GridViewID="GridView1"runat="server"AllowSorting="True"AutoGenerateColumns="False"

                       CellPadding="3"Font-Size="9pt"OnSorting="GridView1_Sorting"BackColor="White"BorderColor="#CCCCCC"BorderStyle="None"BorderWidth="1px">

                       

                       

                            

BoundFieldDataField="身份证号码"HeaderText="用户ID"SortExpression="身份证号码"/>

                           

BoundFieldDataField="姓名"HeaderText="用户姓名"SortExpression="姓名"/>

                           

BoundFieldDataField="员工性别"HeaderText="性别"SortExpression="员工性别"/>

                           

BoundFieldDataField="家庭住址"HeaderText="家庭住址"SortExpression="家庭住址"/>

   SqlConnectionsqlcon;

   stringstrCon="DataSource=(local);Database=北风贸易;Uid=sa;Pwd=sa";

   protectedvoidPage_Load(objectsender,EventArgse)

   {

       DropDownListddl;

       if(!

IsPostBack)

       {

           stringsqlstr="selecttop5*from飞狐工作室";

           sqlcon=newSqlConnection(strCon);

           SqlDataAdaptermyda=newSqlDataAdapter(sqlstr,sqlcon);

           DataSetmyds=newDataSet();

           sqlcon.Open();

           myda.Fill(myds,"飞狐工作室");

           GridView1.DataSource=myds;

           GridView1.DataBind();

           for(inti=0;i<=GridView1.Rows.Count-1;i++)

           {

               DataRowViewmydrv=myds.Tables["飞狐工作室"].DefaultView[i];

               if(Convert.ToString(mydrv["员工性别"]).Trim()=="True")

               {
