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?')");
}
}
}
9.GridView实现自动编号:
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 //清清月儿http://blog.csdn.net/21aspnet
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'");
////当有编辑列时,避免出错,要加的RowState判断
//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?')");
//}
}
if (e.Row.RowIndex != -1)
{
int id = e.Row.RowIndex + 1;
e.Row.Cells[0].Text = id.ToString();
}
}
注意这时最好把前台的第一列的表头该为“编号”,因为以前的第一列被“吃掉”了。
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
<FooterStyle BackColor="White" ForeColor="#000066" />
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
<asp:BoundField DataField="姓名" HeaderText="用户姓名" />
<asp:BoundField DataField="员工性别" HeaderText="性别" />
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
<asp:CommandField HeaderText="选择" ShowSelectButton="True" />
<asp:CommandField HeaderText="编辑" ShowEditButton="True" />
<asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
</Columns>
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
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 DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HeaderText="CreationDate" />
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 ID="GridView1" runat="server">
<columns>
<asp :BoundField DataField="CreationDate"
DataFormatString="{0:M-dd-yyyy}"
HtmlEncode="false"
HeaderText="CreationDate" />
</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 ID="GridView3" runat="server" >
<columns>
<asp :TemplateField HeaderText="CreationDate" >
<edititemtemplate>
<asp :Label ID="Label1" runat="server"
Text='<%# Eval("CreationDate", "{0:M-dd-yyyy}") %>'>
</asp>
</edititemtemplate>
<itemtemplate>
<asp :Label ID="Label1" runat="server"
Text=’<%# Bind("CreationDate", "{0:M-dd-yyyy}") %>'>
</asp>
</itemtemplate>
</asp>
</columns>
</asp>
前台代码:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="身份证号码"
DataSourceID="SqlDataSource1" AllowSorting="True" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="身份证号码" ReadOnly="True" SortExpression="身份证号码" />
<asp:BoundField DataField="姓名" HeaderText="姓名" SortExpression="姓名" />
<asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />
<asp:BoundField DataField="出生日期" HeaderText="出生日期" SortExpression="出生日期" />
<asp:BoundField DataField="起薪" HeaderText="起薪" SortExpression="起薪" />
</Columns>
<FooterStyle BackColor="White" ForeColor="#000066" />
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:北风贸易ConnectionString1 %>"
SelectCommand="SELECT top 5 [出生日期], [起薪], [身份证号码], [姓名], [家庭住址], [邮政编码] FROM [飞狐工作室]" DataSourceMode="DataReader"></asp:SqlDataSource>
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
