Databases :: Error "Property Evaluation Failed" For "Response.End" When Exporting Datatable To Excel
Jan 13, 2010
I catch the error of "Property Evaluation Failed" for the sentence "Response.End" in the following code.
Sub exportToExcel(ByVal _DT As DataTable)
Dim dt As DataTable = _DT
Dim attachment As String = "attachment; filename=userlist.xls"
Response.ClearContent() [code]....
I am having crystal report nto my application. By using report document I am trying to export the report into pdf. But while trying that I am getting the exception "property evaluation failed" but the report is exporting. I want to know how to avoid that exception. So far I googled for that exception, I got some idea about calling response.end internally. But yet its not clear to me. I am giving some code sample here:
I have a code block that contains around 320 lines of code. Everything runs fine when i debug it until i reach the section that updates a sql datasource. I am using:
I have 38 lines of update parameters before i call the sqldscc.Update When i put a break point before the update parameters all the values are correct at the break point at the end all the values are "Property Valuation Failed"?. I'm not using any response.end, response.redirect or server.transfer
I am usig ADO.NET to fetch a Dataset and then exporting the data to excel using Response.Write with response type set as excel. However when I run the application I am getting the following error in the browser."Cannot view XML input using XSL style sheet. Please correct the error and then click theRefresh button, or try again later."Anybody has any idea on why do we get this error and any pointers to resolve this error? By the way the same code does works on another machine, it's just not working on few machines.
I've created a function that takes a datatable and exports it to excel by creating a Table.
When the file exported excel says "this file is in a different format than it's extension, do you wnat to open it anyway?". I'd like to get rid of this message if I can. and...There is an extra row at the top of the the excel file (row 0) and it's empty.
I've been working on this for a while and everything that I have read seems to tell me to use the same setup. I have been able to export the data to an xls file on my local C drive but that won't work when hosted on the server as I'll want users to export their data to their local machines as well... I guess the issue I'm having (or at least what I think am having) has to do with my response.end() function. I'll give you my code that works and the one that doesn't... In the end they will both do the same thing...Here is the code I've been playing with for my button:
[Code]....
Now here is where it will at least save on my local drive via a button in my drop down menu:
[Code]....
I need to prompt the user to save the file to a location and perhaps be able to name the file etc
i did the mysql data export into excel in row wise when button click... here i want the same data export into columns wise..i used datatable and dataset for this function.. here i need all data should export in column..here i used some code..

This is an ASP.NET web app built using VS2008. I created a standalone class with a method that exports the entire page, text fields, gridviews, images, everything to an Excel worksheet. It works fine. When I dropped the same class in another web app and tried to call it from a page, I get this error message:
I'm exporting data to Excel. I've to put some headings, some data from datatable and again some footer text. For that I'm using following Code. It works fine locally but when I publish it it gives error while saving excel file as I'm hosting it on shared server.
I am exporting GridView to Excel but keep on getting a pop up "The file you are trying to open, 'somefile.xls' is in a different format than specidied by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?When I click "yes" the file opens fine. But why I am getting the pop up at the first place.Also as I have Office 2007 on my machine
I am trying to write a bit of code that will export the current contents of a gridview to an excel file on the local system. I've looked at several examples on how to do it and implemented it. However, i am unable to get the gridview to export the data.
Here's the basics of what i am doing:
I'm using httpcontext.current.response to specify the file contents and filename. creating Stringwriter and htmltextwriter objects.
then rendering the table into the htmlwriter then rendering the htmlwriter to the response.
however, regardless of how large or small the table i am working with is, i keep getting the following error:
[Code]....
Visual Studio opens a file called ScriptResource.axd and the error is noted in the following section of code at the throw error line.
[Code]....
I have included the Public Overrides Sub VerifyRenderingInServerForm(ByVal ctl As Control) method as suggested by others but this has not resolved my issue. I am not sure how to proceed.
I have a web page with a gridview control and a button for Exporting to Excel
I get following error when exporting to Excel.
"The file you are trying to open, 'someFileName[1].xls, is in a different format than specified by the file extension. Verify that file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"
Clicking Yes opens the file. I would like to avoid showing the above error to the users.
Following code is used from the click event. I've left the commented code here to show what I've tried based on results from internet search. I have Microsoft Office Excel 2007 on local PC.
I'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'm exporting a Gridview to excel. I get all the gridview header and content in excel in addition to that i need to add a header text like report name in header of the excel sheet with line break in header.
I tried the solution in this link [URL] by adding
Table.Caption = "Header Text" Table.CaptionAlign = TableCaptionAlign.Top but i get error Reference to a non shared member requires an object reference.
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.
I have a project in vb with a gridview in a multiview and i want to save in a workbook excel the gridview displayed data. I have read many articles but in the end i have downloaded the code from URL...and i adapted for my code. The problem is that when i press the ExporttoExcel button it's exporting only this...I cannot figure out that is the problem.
