1.GridView无代码分页排序
效果图 1.AllowSorting设为Trueaspx代码中是AllowSortingTrue 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PageSize12。 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

7.鼠标移到GridView某一行时改变该行的背景色方法二
效果图 做法和上面的一样就是代码不同 protected void GridView1_RowDataBound(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, cthis.style.backgroundColor;this.style.backgroundColor#00A9FF); // //当鼠标移开时还原背景色 // e.Row.Attributes.Add(onmouseout, this.style.backgroundColorc); // } //} //如果是绑定数据行 if (e.Row.RowType DataControlRowType.DataRow) { //鼠标经过时行背景色变 e.Row.Attributes.Add(onmouseover, this.style.backgroundColor#E6F5FA); //鼠标移出时行背景色变 e.Row.Attributes.Add(onmouseout, this.style.backgroundColor#FFFFFF); } }
8.GridView实现删除时弹出确认对话框
效果图 实现方法 双击GridView的OnRowDataBound事件 在后台的GridView1_RowDataBound()方法添加代码最后代码如下所示 protected void GridView1_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[6].Controls[0]).Attributes.Add(onclick, javascript:return confirm(你确认要删除\ e.Row.Cells[1].Text \吗?)); } } }

10.GridView实现自定义时间货币等字符串格式
效果图 图1-未格式化前 图2-格式化后 解决方法 在asp.net 2.0中如果要在绑定列中显示比如日期格式等如果用下面的方法是显示不了的
asp :BoundField DataFieldCreationDate DataFormatString{0:M-dd-yyyy} HeaderTextCreationDate /
主要是由于htmlencode属性默认设置为true,已防止XSS攻击安全起见而用的所以可以有以下两种方法解决
1、
asp :GridView IDGridView1 runatserver columns asp :BoundField DataFieldCreationDate DataFormatString{0:M-dd-yyyy} HtmlEncodefalse HeaderTextCreationDate / /columns /asp
将htmlencode设置为false即可
另外的解决方法为使用模版列
asp :GridView IDGridView3 runatserver columns asp :TemplateField HeaderTextCreationDate edititemtemplate asp :Label IDLabel1 runatserver Text%# Eval(CreationDate, {0:M-dd-yyyy}) % /asp /edititemtemplate itemtemplate asp :Label IDLabel1 runatserver Text’%# Bind(CreationDate, {0:M-dd-yyyy}) % /asp /itemtemplate /asp /columns /asp

附录-常用格式化公式 {0:C} 货币 {0:D4}由0填充的4个字符宽的字段中显示整数 {0:000.0}四舍五入小数点保留第几位有效数字 {0:N2}小数点保留2位有效数字{0:N2}% 小数点保留2位有效数字加百分号 {0:D}长日期{0:d}短日期{0:yy-MM-dd} 例如07-3-25{0:yyyy-MM-dd} 例如2007-3-25 11.GridView实现用“...”代替超长字符串
效果图 解决方法数据绑定后过滤每一行即可 for (int i 0; i GridView1.Rows.Count - 1; i) { DataRowView mydrv; string gIntro; if (GridView1.PageIndex 0) { mydrv myds.Tables[飞狐工作室].DefaultView[i];//表名 gIntro Convert.ToString(mydrv[家庭住址]);//所要处理的字段 GridView1.Rows[i].Cells[3].Text SubStr(gIntro, 2); } else { mydrv myds.Tables[飞狐工作室].DefaultView[i (5 * GridView1.PageIndex)]; gIntro Convert.ToString(mydrv[家庭住址]); GridView1.Rows[i].Cells[3].Text SubStr(gIntro, 2); } }
调用的方法 public string SubStr(string sString, int nLeng) { if (sString.Length nLeng) { return sString; } string sNewStr sString.Substring(0, nLeng); sNewStr sNewStr ...; return sNewStr; }

效果图 首先设置asp:BoundField DataField家庭住址 HeaderText家庭住址 ItemStyle-Width100 / gridview里有一列绑定的数据很长显示的时候在一行里面显示页面拉得很宽。 原因是连续英文段为一个整体导致的在RowDataBound中添加上了一句e.Row.Cells[2].Style.Add(word-break, break-all)就可以。
如果要给所有的列增加此属性 protected void Page_Load(object sender, EventArgs e) { //正常换行 GridView1.Attributes.Add(style, word-break:keep-all;word-wrap:normal); //下面这行是自动换行 GridView1.Attributes.Add(style, word-break:break-all;word-wrap:break-word); if (!IsPostBack) { bind();//调用数据绑定即可 } }总之善用CSS的word-break:break-all;word-wrap:break-word属性即可这个属性是通用的对于顽固的南换行问题都可以解决不局限于GridView。 12.GridView显示隐藏某一列 本方案为月儿独创不同于网上其他方式我觉得用一个CheckBox更人性化这样可以隐藏不必要的列让用户自己选择需要出现的列在处理多列时这是一个很好的解决方案
效果图 图1-开始 图2-点击显示的CheckBox后
解决方案 public void bind() { string sqlstr select top 5 * from 飞狐工作室; sqlcon new SqlConnection(strCon); SqlDataAdapter myda new SqlDataAdapter(sqlstr, sqlcon); DataSet myds new DataSet(); sqlcon.Open(); myda.Fill(myds, 飞狐工作室); GridView1.DataSource myds; GridView1.DataKeyNames new string[] { 身份证号码 }; GridView1.DataBind(); sqlcon.Close(); GridView1.Columns[3].Visible false;//一开始隐藏 CheckBox1.Checked false;//如果不这样后面的代码会把他True }
双击CheckBox1在CheckedChanged方法里写上代码最后代码如下 protected void CheckBox1_CheckedChanged(object sender, EventArgs e) { GridView1.Columns[3].Visible! GridView1.Columns[3].Visible; Response.Write(GridView1的第4列现在的显示隐藏状态是GridView1.Columns[3].Visible.ToString()); }
注意CheckBox1的AutoPostBack要True

读取Excel数据的代码这个很简单的 private DataSet CreateDataSource() { string strCon; strCon ProviderMicrosoft.Jet.OLEDB.4.0;Data Source Server.MapPath(excel.xls) ; Extended PropertiesExcel 8.0;; OleDbConnection olecon new OleDbConnection(strCon); OleDbDataAdapter myda new OleDbDataAdapter(SELECT * FROM [Sheet1$], strCon); DataSet myds new DataSet(); myda.Fill(myds); return myds; } protected void Button1_Click(object sender, EventArgs e) { GridView1.DataSource CreateDataSource(); GridView1.DataBind(); } 很多朋友问点击GridView中自定义的一个模版内的控件如何知道是点击的哪一行。 可能很多朋友都是熟悉了DataGrid的模式说GridView还没有DataGrid好。 其实GridView还是非常强大的。特别是配合DetailsView来使用。 其实如何得到当前选择的行呢很简单使用Parent属性就可以呀。 比如我们自定义了一个LinkButton那么当我们点击这个控件时如何知道它在GridView中所在的行呢很简单请看下面的代码。
1 protected void LinkButton1_Command(object sender, CommandEventArgs e) 2 { 3 LinkButton lb (LinkButton)sender; 4 DataControlFieldCell dcf (DataControlFieldCell)lb.Parent; 5 GridViewRow gvr (GridViewRow)dcf.Parent; 6 GridView1.SelectedIndex gvr.RowIndex; 7 } 是不是很简单呀我们使用第一个Parent属性的时候就会将LinkButton的范围扩大到DataControlFieldCell当前按钮所在表格中的列单元然后再使用一次Parent属性可以再将列单元的范围扩大到GridViewRow当前列单元所在的行单元这个时候使用行单元的RowIndex属性就可以得到当前行所在表格的序号了。
由于时间关系这个文章先到此。有时间再写其实还有很多技巧不过我觉得如果能融汇贯通应该可以举一反三。 笔者测试wen
