GridView选中、编辑、取消、删除

后台代码：

你可以使用sqlhelper,本文没用。代码如下：

using System;

using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.Data.SqlClient;

public partial class _Default : System.Web.UI.Page

{

SqlConnection sqlcon;

SqlCommand sqlcom;

string strCon = "Data Source=(local);Database=数据库名;Uid=帐号;Pwd=密码";

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

bind();

}

}

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)

{

GridView1.EditIndex = e.NewEditIndex;

bind();

}

//删除

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)

{

string sqlstr = "delete from 表 where id='" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";

sqlcon = new SqlConnection(strCon);

sqlcom = new SqlCommand(sqlstr,sqlcon);

sqlcon.Open();

sqlcom.ExecuteNonQuery();

sqlcon.Close();

bind();

}

//更新

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)

{

sqlcon = new SqlConnection(strCon);

string sqlstr = "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() + "' where id='"

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

sqlcom=new SqlCommand(sqlstr,sqlcon);

sqlcon.Open();

sqlcom.ExecuteNonQuery();

sqlcon.Close();

GridView1.EditIndex = -1;

bind();

}

//取消

protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)

{

GridView1.EditIndex = -1;

bind();

}

//绑定

public void bind()

{

string sqlstr = "select * from 表";

sqlcon = new SqlConnection(strCon);

SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);

DataSet myds = new DataSet();

sqlcon.Open();

myda.Fill(myds, "表");

GridView1.DataSource = myds;

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

GridView1.DataBind();

sqlcon.Close();

}

}
