I've got several XtraGrid Controls each one containing different information, I get some information about the way in which you can export a XtraGrid to an Excel file in the following direction http://www.devexpress.com/Support/Center/p/Q362120.aspx Now Is there any way to export the each XtraGrid Control to a single Excel file so that every XtraGrid information is exported to a different excel sheet. I tried setting the exporting path direction to the same Excel file, but when the first exporting process is done, the second exporting process just overrides the excel file and so on. I tried

I'm using the Excel interop and it seems to be creating a process every time I call new Microsoft.Office.Interop.Excel.Application() And never ending the process even though I call xlApp.Quit(); How can I get the processes to end? Are you releasing all of your references? (Which means you have to save them in the first place). For example here's what's in my dispose from some excel interop(): public void Dispose() { if(!this.disposed) { if(cell != null) Marshal.FinalReleaseComObject(cell); if(cells != null) Marshal.FinalReleaseComObject(cells); if(worksheet != null) Marshal

I have created an excel workbook with many sheets like sheet1, sheet2,... etc. How can I rename these tab names dynamically in C#? You didn't spedify how do you access the excel file. However, example from here might be useful for you if you're using Microsoft.Office.Interop.Excel . Note that it opens first sheet in the file, line: (Worksheet)xlBook.Worksheets.get_Item(1) using Excel = Microsoft.Office.Interop.Excel; object oMissing = System.Reflection.Missing.Value; Excel.ApplicationClass xl=new Excel.ApplicationClass(); Excel.Workbook xlBook; Excel.Worksheet xlSheet; string laPath = Server

Ok, so I'm trying to set the value of a cell with the excel interop library. I am able to do it with the following: sheet.Cells[row, col] = value; but it's terribly slow for how many I'm setting. So I'm trying to go this route: Range excelRange = sheet.UsedRange; excelRange.Cells.set_Item(row, col, value); The code executes, but no data is put in the cell. Any suggestions on what I'm missing? Thanks! Your first method should work fine for any reasonable (and a lot of unreasonable) amounts of cells, provided you have disabled screen updating ( Application.ScreenUpdating = false ). The

I am trying to open (or create a new xls) Excel file and write some values to it. Although, the program below works just fine if I simply create a new xls file, I encounter the some problem in line **mWorkBook = oXL.Workbooks.Open (path, 0, false, 5, "", "", false, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false);** Here's the error: 'LOG.xls' cannot be accessed. The file may be corrupted, located on a server that is not responding, or read-only. It's not read-only, it's not corrupted(because sometime the file is created on Run Time). What is the

I am having trouble releasing Excel Interop Com Objects which is causing my c# application to crash when I attempt to save and then close an Excel workbook created via Excel Interop. I feel the issue is that in some cases I am using '2 dots' with excel interop COM objects which from what I've read is not allowed. I have eliminated 2 dots from most lines of code, but I am having troulbe figuring out a way to recreate the following lines of code so that they only use one dot. If anyone has any suggestions I would greatly appreciate it. workbook = (Excel.Workbook)app.Workbooks.Open(startForm

I am building a report using the microsoft.interop.excel library in C#. I have something like this: Range rangeTarget; . . . rangeTarget = worksheet.get_Range("C" + row, "N" + row); I want the range to display its values as whole numbers i.e. with no decimal places. I've tried rangeTarge.AutoFormat, but have no idea how to use it. Any Ideas ? Thanks. see MSDN Microsoft.Office.Tools.Excel.NamedRange namedRange1 = this.Controls.AddNamedRange(this.Range["A1", "A5"], "namedRange1"); namedRange1.NoteText("This is a Formatting test", missing, missing); namedRange1.Value2 = "Martha"; namedRange1.Font
