I am using epplus to create excel with chart where I have added 2 column charts in excel sheet and we are using this excel sheet as template.
Now, If any of the chart doesnt have data then I want to hide/delete the chart from the sheet while downloading. But, I am unable to find such option.
Below is my code
ExcelDrawing excelDrawing = excelWorksheet.Drawings["Chart1"];
After this I am not getting any option in excelDrawing object to hide/show/delete OR else do I need to go in different way ?
Any help on this appreciated !

i wanna export pivot table in excel with report filter, i'm currently using EPPLUS but it can not possible with epplus. Please anyone tell which library should i use to export pivot with report filter in excel..
You can try to use Microsoft.Office.Interop.Excel for pivot tables in Excel using C#.
A code example of using pivot table of the Office.Interop is:
PivotTable pt = (PivotTable)activeWorksheet.PivotTables("PivotTable1");
PivotField pf = (PivotField)pt.PivotFields(11);
pf.ClearAllFilters();
This article also gives more information about creating pivot tables.

I have created a function to read an excel sheet using OLEDb. I can make the connection and read the excel sheet.
With DbDataReader and a while loop using Read() method I retrieved all cell data from an excel sheet.
I want to check the alignment info of each cell. If a cell is left-aligned, I will pick data from those left-aligned cells.
How can I do that?
Sorry It is a stupid question but I really need it.
Thanks
You can't do that with Excel OleDb provider; cell alignment isn't exposed. The OleDb provider makes the Excel spreadsheet mimic a database table and database columns don't have alignment.
You'll have to use Excel interop if you need to that. See this question for help on that.
I have the excel sheet, I want to keep it as datasource to the gridview. gridview will be editable so whatever the data updated sholud be write to again in excel sheet with respected location in sheet.
How can I do this?
You could use the Jet driver to select from the spreadsheet via OLEDB. Your spreadsheet will need to be laid out in a table-like fashion, and you can have some painful problems with type guessing, but this may work for your situation.
