6.鼠标移到GridView某一行时改变该行的背景色方法一:

效果图:
做法:
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)

{

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");

}

}

}

前台代码:

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", "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

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?')");

}

}

}


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javascript:void(0)

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


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;

}
