Hi,

I am trying to fill dropdown from excel column.
Every thing was fine ,but it's displaying system.data.datarow instead of Values in dropdown list.

wat's the mistake in the following code.

C#

           DataTable dt = new DataTable();
          string connString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:\OnCall Tracker_2011.xls;Extended Properties='Excel 8.0;HDR=NO'"; 
            using (OleDbConnection conn = new OleDbConnection(connString))
            {   
                conn.Open();    
                //Where [F1] = column one, [F2] = column two etc, etc.              
                //OleDbCommand objCmdSelect = new OleDbCommand(sqlQuery, conn);                   
                //objCmdSelect.ExecuteNonQuery();
                string sqlQuery = "select distinct [F1] AS [id] from [July -11$]";
                OleDbDataAdapter adapter = new OleDbDataAdapter(sqlQuery, conn);
                adapter.Fill(dt);
            DropDownList1.DataSource = dt;
            DropDownList1.DataBind();
}

Thanks In Advance

Try this

C#

DropDownList1.DataTextField = "id";
DropDownList1.DataValueField = "id";
DropDownList1.DataSource = dt;
DropDownList1.DataBind();

Solution 2

Try adding the following code below DropDownList1.DataSource = dt;

C#

DropDownList1.DataTextField= dt.Columns[0].ToString();
DropDownList1.DataValueField = dt.Columns[0].ToString();

My 5. I was under impression on ComboBox and suggested DisplayMember and ValueMember.
