Get Blank Column In Datatable From Excel File?

Mar 15, 2011

I am using following code to get the columns from excel into datatable. In that in my excel file columns started from C to E means columns A and B is blank(Headers also). When i am reading excel file into datatable that time it's taking columns C to E. I want A and B also.Means when i am reading file that time blank columns are avoiding. I want blank columns should be read.

Excel File Data:

A B C D E

1 2 3

5 6 7

And in Datatable i am getting:

C D E

1 2 3

5 6 7

So i want Columns in Datatable also just like excel.

String
connString = ApplicationSetting
.GenerateExcelProvider(FilePath);[code]....

DataSource Controls :: Read All Rows In One Column From Excel File

Jan 10, 2010

I need a way to read all the rows in one column from an Excel file that the user picks from a fileupload control. I tried saving the excel file on the webserver with the upload control and then opening it with a OleDbConnection but that fails when running it from the webserver and gives the error:

Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

This works fine when just running it localhost, so i figured it might be a problem with security level at the webserver which i cant change. Instead i tried doing it with a streamreader direct from the fileupload control and because theres no need for saving the excel file on the server, but im not sure how to query the rows i need this way.

DataSource Controls :: Inserting A Blank DataRow Into A DataTable?

May 21, 2010

I have a DataTable that's populated with Data. I'm looping through it and checking to see what the contents of the first cell of the first column are. If they have the same value on the current iteration as the previous, I want to insert a blank row into my DataTable. The problem is that the new row is being added to the end of the DataTable instead of between the two rows. How can I get it not to append the row to the end. This is what I'm doing:

Web Forms :: Download To Excel From Datatable

Mar 10, 2011

I have a download which is in a class below

[Code]....

and on my page i have a download button which runs a webhandler like below

[Code]....

when the download button is clicked it runs the code below

[Code]....

the dtresults is a datatable that is created on the page. the problem i have is if the cell has commas in like '12 london road, london, le126yr' in the database then its putting it onto the next line in the exported csv file and treating it as a carriage return rather than keeping all on the same line. I have done a replace in the code to replace the comma's to replace them with nothing but it doesnt seem to be working.

C# - Importing An Excel WorkSheet Into A Datatable

May 13, 2010

I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.

I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db. My question is what can anyone give me code to open an excel file, know what line the data starts on in the file, and import the data into a datable object?

Exporting Datatable Into Excel Using Vb.net Code Behind?

Mar 16, 2010

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:

I need to prompt the user to save the file to a location and perhaps be able to name the file etc
