爱她就要好好地呵护她

 

.net2005中对asp.net中GridView的常用操作

1、先绑定数据源
 private void fBind()
    {
        SYJ.sqlServer f = new SYJ.sqlServer(SYJ.common.gDbConnStr(""));
        string strF = "select * from tFunctionWeb";
        DataSet ds = f.sqlSelectDS(strF);
        ViewState["dsPage"] = ds;                    //这在后面的分页中用到;
        this.GridView1.DataSource = ds;
        this.GridView1.DataBind();
    }
2、分页事件
 protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        this.GridView1.PageIndex = e.NewPageIndex;
        this.GridView1.DataSource = ViewState["dsPage"];
        this.GridView1.DataBind();
    }
3、删除事件
 protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        SYJ.sqlServer f = new SYJ.sqlServer(SYJ.common.gDbConnStr(""));
        int fid = int.Parse(this.GridView1.DataKeys[e.RowIndex].Values[0].ToString());
        string strF = "delete  from tFunctionWeb where fid="+fid;
        //string strF2 = "delete from ";
        if (f.sqlInsertUpdateDelete(strF) > 0)
        {
            SYJ.common.msgBox(this, "删除成功!");
        }
        else
        {
            SYJ.common.msgBox(this, "对不起,删除失败!");
        }
        this.fBind();
    }
4、删除确认框事件
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Cells[e.Row.Cells.Count - 1].Attributes.Add("onclick", "return confirm('确定要永久删除该功能页面吗?');");
        }
    } 

    /// <summary>
    /// (编辑)取消事件
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        GridView1.EditIndex = -1;
        this.fBind();
    }

    /// <summary>
    /// 编辑事件
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        GridView1.EditIndex = e.NewEditIndex;
        this.fBind();
    }

    /// <summary>
    /// (编辑)更新事件
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        SYJ.sqlServer update = new SYJ.sqlServer(SYJ.common.gDbConnStr(""));
        //   string RegName = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("tbRegName")).Text.Trim();   /*需要插入模板列,比较麻烦*/
       
        TextBox tbRegName = (TextBox)this.GridView1.Rows[e.RowIndex].Cells[1].Controls[0];//通过找到编辑所在行的列数即可
        string RegName2 = tbRegName.Text;
        if (!string.IsNullOrEmpty(RegName2))
        {
            StringBuilder strsql = new StringBuilder("UPDATE ai_ObjComm SET RegName='")
                                   .Append(RegName2)
                                   .Append("'")
                                   .Append(" WHERE ID='")
                                   .Append(GridView1.DataKeys[e.RowIndex].Value)
                                   .Append("'");

            try
            {
                update.sqlInsertUpdateDelete(strsql.ToString());
                GridView1.EditIndex = -1;
                fBind();
                Response.Write("<script>alert('信息更新成功');</script>");
            }
            catch (Exception ex)
            {
                string message = "修改车辆资料失败,详细信息是:"+ex.Message.Replace("\r\n", "");
                Response.Write("<script>alert(message);</script>");
            }
        }
        else
        {
            Response.Write("<script>alert('车牌号码不能为空,请重新输入');</script>");
        }
    }
    /// <summary>
    /// 我们可能要根据需要,对gridview中的数据进行特殊的显示,比如当某样商品库存为0时,要求gridview中以不同颜色进行显示,这时,可以按如下的方法进行:
   /// 首先,gridview提供了rowdatabound事件,该事件在gridview中每行被创建并且绑定到datasource控件后被触发,因此,我们可以利用该事件去检查库存是否为0,如果为0的话,将所在行的北京颜色设置为黄色,
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            int isHaveLock = Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "isHaveLock"));
            if (isHaveLock == 0)
                e.Row.BackColor = Color.Yellow;
        }

    }
