Solution 1

C#

DataSet dsReport = new DataSet();
...
dsReport.Tables[0].Load(drReport);

The DataSet is empty. Try adding to it.

As already explained by PIEBALDconsult the problem is there is no Table[0] in the dataset thats why you are getting error. Change your data retrieval logic as follows.

C#

var sqlConnection = new SQLConnectionStrings();
DataSet dsReport = new DataSet();

using(var conReport = new SqlConnection(connString))
{
    conReport.Open();
    var cmdReport = new SqlCommand(baseQuery, conn);
    var myDataAdapter = new SqlDataAdapter(command);

    myDataAdapter.Fill(dsReport);
}

This will populate dsReport.Tables[0] that you can further use for reporting.
