1.字段过长截取字符串

1.1 截取字符串类

 

可以直接substring
也可以<%# Utility.Common.GetShow( Eval("NewTitle").ToString(),20,true) %><td><%#fcwms.Common.GetContent.GetShow(Eval("com_address").ToString(), 19, true)%> </td>/// <summary >/// 按字节数截取字符串,中文算两个字节,全角字符算两个字节,大写字母也算两个字节/// </summary >/// <param name="strSrc">要处理的字符串</param>/// <param name="count">要保留的字节数</param>/// <param name="withPoint">设置截取后加不加省略号( "... ")默认的传true</param>/// <returns></returns>public static string GetStrByByteCount(string strSrc, int count, bool withPoint){Regex regex = new Regex("[\u4e00-\u9fa5]+", RegexOptions.Compiled);char[] stringChar = strSrc.ToCharArray();StringBuilder sb = new StringBuilder();int nLength = 0;bool isCut = false;for (int i = 0; i < stringChar.Length; i++){if ((regex.IsMatch((stringChar[i]).ToString())) || (stringChar[i] > 65280 && stringChar[i] < 65375) || (stringChar[i] > 64 && stringChar[i] < 91)){nLength += 2;if (nLength > count){isCut = true;break;}sb.Append(stringChar[i]);}else{nLength = nLength + 1;if (nLength > count){isCut = true;break;}sb.Append(stringChar[i]);}}if (isCut){if (withPoint){return sb.ToString() + "...";}else{return sb.ToString();}}else{return sb.ToString();}}

 

1.2 示例

 <td><asp:Label ID="Label14" runat="server" Text='<%# fcwms.Common.GetContent.GetShow(Eval("com_address").ToString(),19,true)%>'  ToolTip='<%# Eval("com_address")%>'></asp:Label></td>

 

<td><asp:Label ID="lblMatNM" runat="server" Text='<%#Eval("matNM").ToString().Length >10?Eval ("matNM").ToString().Substring (0,10)+"...":Eval ("matNM").ToString ()%>' ToolTip ='<%#Eval("matNM")%>'></asp:Label></td>

无提示：

 <td><%#fcwms.Common.GetContent.GetShow(Eval("com_address").ToString(),19,true)%></td> 

2.时间格式化

<%# Convert.ToDateTime(Eval("time")).ToString("yyyy-MM-dd HH:mm")%> <%#string.Format("{0:yyyy-MM-dd HH:mm}", Eval("time"))%>

<%#string.Format("{0:g}",Eval("add_time"))%>   2018/4/2 15:03

3.合并单元格

 <td runat="server" id="tdName"><%#Eval("td_name")%></td> 

rptList.DataSource = pds;rptList.DataBind();//合并方法放到数据邦定之后for (int i = rptList.Items.Count - 1; i > 0; i--){HtmlTableCell oCell_Previous = rptList.Items[i - 1].FindControl("tdName") as HtmlTableCell;HtmlTableCell oCell = rptList.Items[i].FindControl("tdName") as HtmlTableCell;oCell.RowSpan = (oCell.RowSpan == -1) ? 1 : oCell.RowSpan;oCell_Previous.RowSpan = (oCell_Previous.RowSpan == -1) ? 1 : oCell_Previous.RowSpan;if (oCell.InnerText == oCell_Previous.InnerText){oCell.Visible = false;oCell_Previous.RowSpan += oCell.RowSpan;}}
