View 17 RepliesI have a GridView populated by an ObjectDataSource. I also have several DropDownLists filtering the ObjectDataSource. I found a link providing a way to export a DataSet (or DataTable) to Excel here:
http://msmvps.com/blogs/deborahk/archive/2009/07/23/writing-data-from-a-datatable-to-excel.aspx
ow I can ensure that filters applied to the ObjectDataSource when the method is called are applied. In short, how can I ensure what the UI is displaying is what the file will include when exported?
I'm creating an ASP.NET MVC 2 (RTM) project that uses areas. The Index action of the Home controller of one area needs to use RenderAction to generate a sub-section of the page. The action called is also defined in the same Home controller. So the call should just be:
<% Html.RenderAction("List") %>
However, I get an exception:A public action method 'List' was not found on controller 'RareBridge.Web.Areas.Events.Controllers.HomeController'.
Note that I'm not in the "Events" area! I'm in a completely different area. If I remove the "Events" home controller, then the exception still occurs but names a different controller (still not the one I want it to call).
I've also tried providing the controller name and area to the RenderAction method, but the same exception occurs. What is going on here?

I am looking for a way to figure out the current URL that the page is currently on (NOT what the asp.net page currently is, but where the CODE is at). ie. My web app is located at: [URL] my code is: String page = [URL]
String response = GetResponse(page); //basically the above code goes to the website [URL] and parses the HTML within it and brings it back and populates the variable string "response". But, sometimes the [URL] throws me a curve ball and redirects me to: [URL] I want to be able to use a try/catch to be able to "catch" the error of a different page: ie validateUser.aspx. So, I need to do to this: try
{
String page = [URL];
String response = GetResponse(page);
}
catch
{
//code to check the behind URL to see if [URL] is the URL OR IF [URL] is the current URL
}
understand I know how to find the URL of the current page the web app is on. I need to find the current page that threw the exception during the execution of the code behind.
I have a static class with serveral static methods. In these methods, I'm trying to access the current thread's context using HttpContext.Current. For example:
var userName = HttpContext.Current.User.Identity.Name;
However, when I do that, I receive a NullReferenceException, the infamous "Object reference not set to an instance of an object."
I am building in error-logging into my site, and want to be able to get hold of the current page name that the error occurred in, as well as the specific subroutine or function, to then pass to a VB.NET function. Is there anyway to get hold of this information without hard-coding the names manually? For example,
Dim strCurrentPageName = ???
Dim strCurrentRoutine = ???
How can I export data from a Gridview to excel and once exported the data should be formatted in right to left (arabic) manner. How can I achieve this?
View 2 RepliesI've got an .rdlc report which I print from my .net app (C# Visual Studio 2005), where I use a RemoteReportPrinter object. I give it as parameters the server name, report name, report parameters, etc. Works fine. My question is, I would live to do an analagous export of that report to Excel. Set it up exactly the same, but have it export to Excel rather than print, probably using some other type of object than RemoteReportPrinter.

I am trying to create double and number format cells in excel using NPOI library. I used code like
Dim cell As HSSFCell = row.CreateCell(j)
cell.SetCellValue(Double.Parse(dr(col).ToString))
In excel numbers are aligning right but when I check format it is showing in "General"
then I changed my code to like below
Dim cell As HSSFCell = row.CreateCell(j)
cell.SetCellValue(Double.Parse(dr(col).ToString))
Dim cellStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle
cellStyle.DataFormat = HSSFDataFormat.GetBuiltinFormat("#,#0.0")
cell.CellStyle = cellStyle
Then While opening file it is giving error and also taking so long to open. But Excel format showing in "Number" error showing is like below.

View 4 RepliesI have a GridView that I want to export to Excel. When I use the sample code I find online, it exports the content to Excel just fine, but for some reason it also clears out all grid lines outside of my exported table.
For your average excel user this is easy enough to fix, but I need this solution to work for everyone.
So then is there a way to export the data in a GridView into an Excel Workbook so that it looks like it was just typed into Excel? I've pasted the code I am using below, assume that a GridView called toPrint exists and has accurate data.
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=" + name + "_Registration_Forms.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
Page.EnableViewState = false;
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
toPrint.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
EDIT: Found one partial solution. If I export as a comma-delimited list and set the header to be a CSV file, it opens fine and all grid lines (even those outside of the exported data) are showing. The only problem with this of course is having to strip out every comma and newline character from my values before exporting them.
