C# - Data Table To Excel Conversion Leaves Server Side Button Non Responsive In SharePoint WebPart?
Apr 29, 2010
We have a web part on which we display some data in a grid. We are exporting grid's underlying datatable to Excel and displaying Open - Save - Cancel dialouge box on click of a server side button.Following is the code we are executing on click of server side button.
this.Page.Response.Clear();
this.Page.Response.AppendHeader("Content-Disposition", "attachment; filename=MyTasks.xls");
this.Page.Response.ContentType = "application/ms-excel";
this.Page.Response.Write("...here goes my well formated html....");
this.Page.Response.End();
Problem is that when i click on Cancel in the diaglouge box then dialogue box to Open/Save excel disappears but all the server side buttons placed on my web part becomes non responsive, on click of any of those buttons their server side click event does not get fired

I am new in sharepoint development. I have 2 webparts attached on a page. The first webpart (MyTestingWebpart1) basically it does only inserting of data and the other webpart (MyTestingWebpart[2]) displays the records from the database. Now my problem is when I try to click on the save button, somehow I don't know how to refresh the webpart that displays the newly inserted record. Is this possible?
I have added a query at the page load event of MyTestingWebPart[2]. Both of the webparts attached are web user controls.
Sorry, not sure if this is the right place for this. I have a requirement to convert Word, Excel and HTML docs to PDF format programmatically, but most information online seems to be talking about client side. What is the best approach for this. I think there would be about 100 conversions a day in production. It's not high volume.
I was wondering if there is any way to always run some server side code when a user leaves a page in ASP.NET. The page Unload event is no good because that doesn't get called if someone clicks on a link. Ideally I'd also like the code to run even if the user closes the browser.
I have built a few custom applications that run on WSS 3 using the Visual Studio 2010 Web application template. When I compile the application, Visual Studio creates the assembly file in the bin directory which I copy over later to the production server (another machine) with WSS 3. The compiled application dll file is copied into the bin folder inside the virtual directory of WSS and runs fine in there
Never worked with Sharepoint, but need to add a WebPart to display a PDF document. How does this work? There is currently some code to add a ReportViewer (SSRS) WebPart, but I need to replace it to display a PDF file (from disk). The PDF file is from a local/network path that is not served publicly. I need to get the PDF content streamed in a web part, setting the content-type along the way. If it helps any, my thoughts are to respond on a different URL (page in the same site), that simply takes some token (get params?) and streams a byte[] and sets the content-type as application/pdf - I could well be completely off the mark. You will need to be quite specific with steps and code/sample/links in the answer.
I am facing error when I am deploying Visual Webpart in Sharepoint . Then its showing following error Could not load file or assembly 'Microsoft.Practices.ObjectBuilder2, Version=2.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I have a problem on adding a webpart to sharepoint page.
I have a blank page in the sharepoint, and I have a custom control uploaded to the site, on adding the webpart the the sharepoint page I get the following error:
"Attempted to use an object that has ceased to exist. (Exception from HRESULT: 0x80030102 (STG_E_REVERTED))"
I get that error even if the sharepoint page is totally blank and so is the web part.
I know it's usually the other way around, but I have some extenuating requirements that must be met (read as "No one bothered to do the research and now I have to bail them out")
I have a standard user control (ascx) that is to be imported into a SharePoint 2007 website. Due to a design constraint, a sharepoint web part that is also needed has to be nested inside of this user control.
So in other words, the user control would have to look something like this:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="foo.ascx.cs" Inherits="foo" %> <div id="container"> ...snipped... <!-- SharePoint web part goes here --> ...snipped... </div>
I have an some code to export data form an SQL database to an Excel spread sheet. the data is entered via a web site and some of it contains multiple lines of information. I need to preserve the multiple lines but excel 2007 continues to put an [?] at the end of each line.Here's what I got so far
CellValue.ToString() // this returns [?][?] at the end of each line for excel 2007 // and a single [?] in excel 2010 CellValue.Replace("[//r]","") // this works correctly for 2010 but still leaves a [?] for 2007 Cellvalue.Replace(Environment.NewLine, "") // this removes all the line breaks.
what can I replace the Environment.NewLine with in order to still have line breaks in both excel 2007 and 2010 (with no [?]) ?
i have a store procedure that load data in a table of SQL SERVER 2008 from an excel file.the issue is, that the excel file have a column of DATE type, and i want that the system interprets the format in it, no matter what comes in it.dd/MM/yyyy mm/dd/yyyyi have an argue about this with my parnerts, cause i think is imposible, if you don't have a format before the process runs.
The idea is that a pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button). These rows contain textboxes, dropdownlists, checkboxes and other input controls. When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on server side, validate it and perform other actions on it.
I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows. put me in the right direction?? Or someone offering a better solution to the problem?

I simply have a lot of data in two columns in an excel spreadsheet of data that I gathered. I want to copy and paste this (manually) into a table that I have created in my ASPNETDB in my ASP.NET web application. I thought it'd be as easy as copy the column, and hit paste in the "table data" view, but it's not (it only pastes one cell).
Is there a way for me to manually copy data from excel and paste it in a table in my SQL Server?
