ASP.NET实现增删改查等功能(Access版)系统之二-GridView绑定数据.

GridView绑定数据.

//绑定

    public void bind(string str)

    {

        string oledbstr = "";

        if (str != null && str != "")

        {

            oledbstr = str;

        }

        else

        {

           oledbstr = "select ID, 姓名,性别,出生日期,工作年限,证件类型,证件号,居住地,Email,手机号码,家庭电话,自我评价 from MResume order by id desc";

        }

        OleDbConnection oledbcon = new OleDbConnection(GetConnection());

        OleDbDataAdapter myda = new OleDbDataAdapter(oledbstr, oledbcon);

        DataSet myds = new DataSet();

        oledbcon.Open();

        myda.Fill(myds, "MResume");

        GridView1.DataSource = myds.Tables[0];     //重点要记住的地方，看这个地方是DataSet or DataTable

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

        GridView1.DataBind();

        oledbcon.Close();

    }

GridView行绑定

/// <summary>

    /// 改变背景色,第二个方法

    /// </summary>

    /// <param name="sender"></param>

    /// <param name="e"></param>

    protected void GridView1_RowDataBound2(object sender, GridViewRowEventArgs e)

    {

        int i;

        //执行循环，保证每条数据都可以更新

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

        {

            //首先判断是否是数据行

            if (e.Row.RowType == DataControlRowType.DataRow)

            {

                //当鼠标停留时更改背景色

                // e.Row.Attributes.Add("onmouseover", "c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'");

                //当鼠标移开时还原背景色

                // e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=c");

            }

        }

        //如果是绑定数据行

        if (e.Row.RowType == DataControlRowType.DataRow)

        {

            //鼠标经过时，行背景色变 00A9FF E6F5FA

            // e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#00A9FF'");

        }

        //如果是绑定数据行

        if (e.Row.RowType == DataControlRowType.DataRow)

        {

            if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)

            {

                //删除提示操作

                 ((LinkButton)e.Row.Cells[13].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text + "\"吗?')");

                e.Row.Cells[11].Text = SubStr(e.Row.Cells[11].Text, 20); //用...代替长文本

            }

        }

        //GridView实现自动编号：

        if (e.Row.RowIndex != -1)

        {

            int id = e.Row.RowIndex + 1;

            e.Row.Cells[0].Text = id.ToString();

        }

        //设置编辑状态文本框长度

        //if ((e.Row.RowState == (DataControlRowState.Edit | DataControlRowState.Alternate)) || (e.Row.RowState == DataControlRowState.Edit))

        //{

        //    TextBox curText;

        //    for (int j = 4; j < 12; j++)

        //    {

        //        curText = (TextBox)e.Row.Cells[j].Controls[0];

        //        curText.Width = Unit.Pixel(60);   //设置长度

        //        curText.Font.Size = FontUnit.Point(11);//设置字号

        //    }

        //}

    }

    public string SubStr(string sString, int nLeng)

    {

        if (sString.Length <= nLeng)

        {

            return sString;

        }

        string sNewStr = sString.Substring(0, nLeng);

        sNewStr = sNewStr + "...";

        return sNewStr;

    }
