CSDN Blog推出文章指数概念，文章指数是对Blog文章综合评分后推算出的，综合评分项分别是该文章的点击量，回复次数，被网摘收录数量，文章长度和文章类型；满分100，每月更新一次。

本文操作数据库使用的是OracleHelp类实现的。参见PetShop

1 gridview的绑定

调用如下：

String ziDianMingChenSql = "select distinct 字典名称,字典编号,zidianmingcheng.SN from zidianmingcheng,xitongzidian where 模块类别= " + "'" + this.LabelLeiBei.Text + "' AND 可否编辑='是' ";
ziDianMingChenGrid(ziDianMingChenSql);

    /// <summary>
    /// 填充GridView
    /// </summary>
    private void ziDianMingChenGrid(String querySql)
    {
        DataSet ds = new DataSet();
        ds = GetData(querySql);

// 清空以前的数据源
GridViewZiDianMingChen.DataSource = null;

// 将ds作为信息栏GridView的数据源
GridViewZiDianMingChen.DataSource = ds;

// 绑定数据
GridViewZiDianMingChen.DataBind();

        // 保存数据源防止丢失 VS的破Bug
        ViewState["GridViewZiDianMingChen_DataSource"] = GridViewZiDianMingChen.DataSource;
        // 保存SQL语句
        ViewState["sqlGridViewZiDianMingChen"] = querySql;
    }

    /// <summary>
    /// 转换SQL查询结果为DataSet
    /// </summary>
    /// <returns>ds</returns>
    private DataSet GetData(String querySql)
    {
        String connStr = OracleHelper.DatabaseConnStr;

// 创建数据集
DataSet ds = OracleHelper.ExeSqlForDataSet(connStr, CommandType.Text, querySql, null);

return ds;
}

2   gridview 换行控制
        this.GridViewZiDianMingChen.Attributes.Add("style", "word-break:keep-all;word-wrap:normal");
        this.GridViewXinXiLan.Attributes.Add("style", "word-break:keep-all;word-wrap:normal");

3 编辑

   /// <summary>
    /// 编辑
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GridViewZiDianMingChen_RowEditing(object sender, GridViewEditEventArgs e)
    {
        GridViewZiDianMingChen.EditIndex = e.NewEditIndex;
        String querySql = "select distinct 字典名称,字典编号,zidianmingcheng.SN from zidianmingcheng,xitongzidian where 模块类别= " + "'" + this.LabelLeiBei.Text + "' AND 可否编辑='是' ";
        ziDianMingChenGrid(querySql);
    }

4 取消

    /// <summary>
    /// 取消
    /// </summary>

    /// <param name="e"></param>
    protected void GridViewZiDianMingChen_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        GridViewZiDianMingChen.EditIndex = -1;
        String querySql = "select distinct 字典名称,字典编号,zidianmingcheng.SN from zidianmingcheng,xitongzidian where 模块类别= " + "'" + this.LabelLeiBei.Text + "' AND 可否编辑='是' ";
        ziDianMingChenGrid(querySql);
    }

5 更新

    /// <summary>
    /// 更新
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GridViewZiDianMingChen_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        string sn = GridViewZiDianMingChen.DataKeys[e.RowIndex].Values[0].ToString().Trim();
        String delXinWenSql = "UPDATE zidianmingcheng SET 字典名称 = '" + ((TextBox)(GridViewZiDianMingChen.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "' WHERE SN = '" + sn + "'";

        OracleConnection conn = new OracleConnection(OracleHelper.DatabaseConnStr);
        conn.Open();
        OracleTransaction trans = conn.BeginTransaction(IsolationLevel.ReadCommitted);

        try
        {
            OracleHelper.ExecuteNonQuery(trans, CommandType.Text, delXinWenSql, null);
            trans.Commit();
        }
        catch (Exception ex)
        {
            trans.Rollback();
            ex.ToString();
        }
        finally
        {
            conn.Close();
        }

GridViewZiDianMingChen.EditIndex = -1;

        String querySql = "select distinct 字典名称,字典编号,zidianmingcheng.SN from zidianmingcheng,xitongzidian where 模块类别= " + "'" + this.LabelLeiBei.Text + "' AND 可否编辑='是' ";
        ziDianMingChenGrid(querySql);
    }

6 删除
    /// <summary>
    /// 删除字典项
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GridViewXinXiLan_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        String sn = GridViewXinXiLan.DataKeys[e.RowIndex].Values[0].ToString().Trim();

String delSql = "DELETE FROM xitongzidian WHERE SN = '" + sn + "'";

        OracleConnection conn = new OracleConnection(OracleHelper.DatabaseConnStr);
        conn.Open();
        OracleTransaction trans = conn.BeginTransaction(IsolationLevel.ReadCommitted);

        try
        {
            OracleHelper.ExecuteNonQuery(trans, CommandType.Text, delSql, null);
            trans.Commit();
        }
        catch (Exception ex)
        {
            trans.Rollback();
            ex.ToString();
        }
        finally
        {
            conn.Close();
        }

        GridViewXinXiLan.EditIndex = -1;
        String ziDianBianHao = this.GridViewZiDianMingChen.Rows[this.GridViewZiDianMingChen.SelectedRow.RowIndex].Cells[2].Text.ToString().Trim();
        String querySql = "SELECT 序号,名称,SN FROM xitongzidian WHERE ID='" + ziDianBianHao + "'";
        fillGridView(querySql);
    }

7 删除弹出对话框

    /// <summary>
    /// 实现删除弹出对话框
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GridViewXinXiLan_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //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)
            {
                ((LinkButton)e.Row.Cells[4].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text.Trim() + "\"吗?')");
            }
        }

}

上面的代码如果一列中有2个控件会报错.用下面的即可.

        //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)
            {
                //((LinkButton)e.Row.Cells[12].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text.Trim() + "\"吗?')");
                ((LinkButton)e.Row.FindControl("LinkButton3")).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text.Trim() + "\"吗?')");
            }
        }

运行图如下：

图2: 点击选择按钮后显示另一个gridview。

3 编辑左边的gridview。可以设置字典编号为只读而使得其不可编辑

4 点击右边的删除按钮

5 点击右边的新增按钮

6 gridview移动框

<asp:GridView ID="GridViewZiDianMingChen" runat="server" AutoGenerateColumns="False"
CellPadding="4" ForeColor="#333333" PageSize="1" EmptyDataText=" " OnRowCancelingEdit="GridViewZiDianMingChen_RowCancelingEdit" OnRowEditing="GridViewZiDianMingChen_RowEditing" OnRowUpdating="GridViewZiDianMingChen_RowUpdating" DataKeyNames="SN" OnSelectedIndexChanged="GridViewZiDianMingChen_SelectedIndexChanged1" Height="5px">
.........
</asp:GridView>
</div>

效果图:(其中的GirdLines设置为Both)好象好看点.

7 空数据时显示表头

8 添加一行空行

        DataTable dt = new DataTable();
        DataRow row = dt.NewRow();
        dt.Columns.Add("建立日期", typeof(string));
        dt.Columns.Add("姓名", typeof(string));
        dt.Columns.Add("类型", typeof(string));
        dt.Columns.Add("名称", typeof(string));
        dt.Columns.Add("开始时间", typeof(string));
        dt.Columns.Add("结束时间", typeof(string));
        dt.Columns.Add("取得证书", typeof(string));
        dt.Columns.Add("备注", typeof(string));
        dt.Columns.Add("经办人", typeof(string));
        dt.Columns.Add("SN", typeof(string));
        row[0] = "2006-6-18";
        row[1] = "张三";
        row[2] = "培训";
        row[3] = "干部培训";
        row[4] = "2006-6-18";
        row[5] = "2006-6-18";
        row[6] = "资格证书";
        row[7] = "无";
        row[8] = "王二";
        row[9] = "234234234";
        dt.Rows.Add(row);

        // 清空以前的数据源
        GridViewTianJia.DataSource = null;

// 将ds作为信息栏GridView的数据源
GridViewTianJia.DataSource = dt;

// 绑定数据
GridViewTianJia.DataBind();

本来有个更好的,不知道怎么写了现在郁闷!

9 隐藏一列

GridViewTianJia.Columns[10].Visible = false;

10 隐藏单元
GridViewTianJia.Rows[0].Cells[10].Visible = false;

11 与dropdownlist的结合

.aspx

<asp:TemplateField HeaderText="类型">

<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("类型") %>'></asp:TextBox>

</EditItemTemplate>

<asp:HiddenField ID="HDLeiXing" runat="server" Value='<%# Eval("类型") %>' />

<asp:DropDownList ID="DropDownListLeiXing" runat="server">

</asp:DropDownList>

</ItemTemplate>

</asp:TemplateField>

.cs

/// <summary>

/// 数据绑定

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

protected void GridViewTianJia_RowDataBound(object sender, GridViewRowEventArgs e)

{

//为DropDownList绑定值

if (((DropDownList)e.Row.FindControl("DropDownListLeiXing")) != null)

{

DropDownList ddlXL = (DropDownList)e.Row.FindControl("DropDownListLeiXing");

//ddlXL.Items.Clear();

//ddlXL.Items.Add("培训");

//ddlXL.Items.Add("进修");

// 奖惩类型

String conn = OracleHelper.DatabaseConnStr;

ddlXL.Items.Clear();

String queryLeiXing = "SELECT 名称 FROM XITONGZIDIAN WHERE ID='03010301' ORDER BY 序号";

OracleDataReader drLeiXing = OracleHelper.ExecuteReader(conn, CommandType.Text, queryLeiXing, null);

while (drLeiXing.Read())

{

ddlXL.Items.Add(drLeiXing.GetString(0).Trim());

}

drLeiXing.Close();

//ddlXL.SelectedValue = ((HiddenField)e.Row.FindControl("HDLeiXing")).Value.ToString().Trim();

ddlXL.Items.Remove(((HiddenField)e.Row.FindControl("HDLeiXing")).Value.ToString().Trim());

ddlXL.Items.Insert(0, ((HiddenField)e.Row.FindControl("HDLeiXing")).Value.ToString().Trim());

}

运行显示:
