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?

I've been searching for various posts on Excel and ASP.Net, and wanted to try and figure out if what I'm attempting has any chance of working. I have a special Excel workbook with a worksheet that has a bunch of calculations and such for various fields that creates an order for his crew. My client uses this Excel worksheet for everything. He's asking me to be able to see online orders (which I have), click a link and have the worksheet be passed down to the client all populated and formatted exactly as is (just adding/editing data).
Is this even possible? I'd have to load this specific .xls file, then open it on the server, save data to various cells, and then do a Save As and then binarystream it down to the client. I'm quite certain there is no version of Excel loaded on the server. So I'm perplexed as to how to accomplish this. Has anyone encountered this situation before and been able to accomplish what's being asked?

View 3 RepliesI want to put up a table with a couple columns, and have the user select a row. This will all be from code; not through a DataConnection. GridView seems like it wants to deal with bound controls. What control should I use? ListView doesn't do columns. A table doesn't seem to allow selection. Specifically, what I'm doing is letting the user find a person in active directory. They'll enter the name, and I'm going to present a list of the Active Directory matched results that they can choose from. Is there already some built in control or package that will do this?

I want to set orientation of excel pages as landscape. Is there any way to do that? Any header information to be added for file being exported to set orientation of pages as landscape?
when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
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.
