Question

What is efficient & simplest way to bind data from excel sheet to repeater or GridView.

Answer 1

I think it is easy to create OleDbDataAdapter and creating a DataSet will do the job.

You can easily bind a DataSet to gridview

eg

var conn = ("Provider=Microsoft.Jet.OLEDB.4.0;" + 
            ("Data Source=add file path here;" +                                
            "Extended Properties=\"Excel 8.0;\"")); 

var query = "SELECT table from [sheet1$]";

var adpterObj = new OleDbDataAdapter(SSQL, conn); 

var ds = new DataSet();

adpterObj.Fill(ds);
GridView1.DataSource = ds.Tables[0].DefaultView; 
GridView1.DataBind();
