you can use dataadapter fill method to implement paging in
dataset.

following is the syntax:

Public Overloads Function Fill(ByVal dataSet As DataSet,
ByVal startRecord As Integer, ByVal maxRecords As Integer,
ByVal srcTable As String) As Integer

WHERE dataSet is a DataSet to fill with records and, if
necessary, schema, startRecord is the zero-based record
number to start with, maxRecords is the maximum number of
records to retrieve, and srcTable is the name of the source
table to use for table mapping.which returns a DataSet
filled with the records based on the page size passed in the
method

for example:

da.fill(ds,0,100,"emp")

for(int i=0;i<ds.Count;i++)
{
arraylist arr=new arraylist();
string abc;
abc=ds.Tables["tablename"].Rows[0][i].ToString();
arr.Add(abc);
}
