Hi there,

I am trying to simply extract an excel data from an uploaded file an put it into a datatable. In this case the excel file has 3 rows but when I fill the datatable I only see row count of 2.

I tried changing HDR:NO; to HDR:YES and vice versa, but no luck. 

What am I doing wrong? (Note: the excel file cannot have a  headerrow)

string connstr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pFilePath + ";Extended Properties=\"Excel 12.0;IMEX=1;HDR:NO;\"";
            OleDbConnection conn = new OleDbConnection(connstr);
            conn.Open();
            DataTable dtTables = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null);
            string strTablename = dtTables.Rows[0]["TABLE_NAME"].ToString();
            string strSQL = "SELECT * FROM [" + strTablename + "]";

            OleDbCommand cmd = new OleDbCommand(strSQL, conn);

            
            DataTable dt = new DataTable();
            OleDbDataAdapter da = new OleDbDataAdapter(cmd);
            da.Fill(dt);
            //At this point row count=2 which doesn't make sense

I am using OLEDBConnection (@"Provider=Microsoft.ACE.OLEDB.12.0;") to connect to the EXCEL file and read contents. When I read the contents, I get all the contents from the excel sheet but i dont get contents for checkboxes placed inside.

My Excel sheet contains set of checkboxes and I need to know If they are checked or not.These checkboxes are controls which are added from Developer tab in EXCEL.

I dont want to use Excel Assemblies for reading contents as it is not recommended. And also i am using OLEDBconnection and want to stick to this .

Awaiting replies from you guys. Thanks in Advance.
