在这里,我将数据集中的数据表导出到excel.如何使数据表的标题字体看起来是粗体.这是我的代码
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=" + fileName + "");
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
StringWriter stringWriter = new StringWriter();
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWriter);
DataGrid dataExportExcel = new DataGrid();
foreach (DataTable table in dtInputParameters.Tables)
{
dataExportExcel.DataSource = table;
dataExportExcel.DataBind();
dataExportExcel.RenderControl(htmlWrite);
htmlWrite.WriteLine("<br/>");
// htmlWrite.AddStyleAttribute(System.Web.UI.HtmlTextWriterStyle.FontWeight, "bold");
}
StringBuilder sbResponseString = new StringBuilder();
sbResponseString.Append("<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\"> <head><meta http-equiv=\"Content-Type\" content=\"text/html;charset=windows-1252\"><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>" + worksheetName + "</x:Name><x:WorksheetOptions><x:Panes></x:Panes></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head> <body>");
sbResponseString.Append(stringWriter + "<table width='800' height='100' align='center' style='text-align:center'");
sbResponseString.Append("</table></body></html>");
HttpContext.Current.Response.Write(sbResponseString.ToString());
HttpContext.Current.Response.End();

这里我从我的Web应用程序调用Restful WCF服务,我不知道如何将对象作为参数传递给这个.这是我的客户端代码:
protected void Button1_Click(object sender, EventArgs e)
{
UserInputParameters stdObj = new UserInputParameters
{
AssociateRefId = "323",
CpecialLoginId = "a@gmail.com",
PartnerId = "aaaa",
FirstName = "aaaa",
LastName = "bbbb",
Comments = "dsada",
CreatedDate = "2013-02-25 15:25:47.077",
Token = "asdadsadasd"
};
string url = "http://localhost:13384/LinkService.svc/TokenInsertion";
try
{
ASCIIEncoding encoding = new ASCIIEncoding();
System.Net.WebRequest webReq = System.Net.WebRequest.Create(url);
webReq.Method = "POST";
webReq.ContentType = "application/json; charset=utf-8";
DataContractJsonSerializer ser = new DataContractJsonSerializer(stdObj.GetType());
StreamWriter writer = new StreamWriter(webReq.GetRequestStream());
writer.Close();
webReq.Headers.Add("URL", "http://localhost:13381/IntegrationCheck/Default.aspx");
System.Net.WebResponse webResp = webReq.GetResponse(); …在这里,我想在<img>标签内连接两个字符串.这该怎么做？？

if(some condition){
comms = (from s in config.PromoRegistration.Communications.Cast<CommunicationGroupConfiguration>()
from c in s.Communications.Cast<CommunicationConfiguration>()
where s.CurrentBrand == true
select c).ToList().FirstOrDefault();
}
else{
comms = (from s in config.Subscriptions.Cast<CommunicationGroupConfiguration>()
from c in s.Communications.Cast<CommunicationConfiguration>()
where s.CurrentBrand == true
select c).ToList().FirstOrDefault();
}
这里
config.PromoRegistration.Communications.Cast<CommunicationGroupConfiguration>()
只有这一部分在这两个查询中发生了变化.如何有效地编写这个查询.任何建议.
我正在使用以下列ExecuteScalar:
cmd.commandtext = "select rodeuser from customer_db_map";
string rodecustomer = cmd.executescalar;
但我需要获得多个专栏,例如:
cmd.commandtext = "select rodeuser,username,password from customer_db_map";
我需要字符串中的每一列:
string rodecustomer = cmd.ExecuteScalar();
string username= cmd.ExecuteScalar();
string password = cmd.ExecuteScalar();
但这是不可能的.这是如何实现的？
在这里,我需要从视图中的模型列表中获取最后一个值而不循环它.这是我的控制器代码
public IList<ProductDetailModel> GetWPDetails()
{
ProductDetailModel Viewmodel;
string funname = "GetCSpecialWPDetails";
List<ProductDetailModel> getWPDetails = new List<ProductDetailModel>();
getWPDetails = objrest.EcommerceWPDetails(funname);
List<ProductDetailModel> WPDetails = new List<ProductDetailModel>();
foreach (var item in getWPDetails)
{
Viewmodel = new ProductDetailModel();
Viewmodel.Productid = item.Productid;
Viewmodel.ProductName = item.ProductName;
Viewmodel.CategoryID = item.CategoryID;
Viewmodel.ProductRate = item.ProductRate;
Viewmodel.DiscountRate = item.DiscountRate;
Viewmodel.imageurl1 = item.imageurl1;
WPDetails.Add(Viewmodel);
}
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString);
SqlCommand cmd = new SqlCommand("SELECT ThemeColor,LayoutDesign FROM dbo.Cpecial_Partner_Design WHERE [PartnerID]='" + Partid + "'", con);
con.Open();
using (SqlDataReader myReader = cmd.ExecuteReader()) …在这里,我需要使用javascript检查按钮单击ie)如果单击按钮A我将调用javascript函数,如果单击按钮B,我将调用另一个javascript函数.
if(document.getElementById('imgBTNExportPPT').clicked == true)
{
ShowDialogExportPPTPOPUP();
}
else if(document.getElementById('btnShowModal').clicked == true)
{
ShowDialogPrintPOPUP();
}
和
<asp:ImageButton ID="imgBTNExportPPT" runat="server" Width="15" Height="15" border="0"
OnClick="imgBTNExportPPT_Click" ImageUrl="~/Images/PPT_icon.png" />
<asp:ImageButton ID="btnShowModal" runat="server" Width="15" Height="15" border="0"
ImageUrl="~/Images/Print_icon.png" onclick="btnShowModal_Click" />
有可能吗??任何建议？
