Raghavendra,

What do you want to serialize from a dataview, it holds no data, it is a
view on a datatable.

Hi,

my dataview its acting like property within a class which is serailized by
using [Serializable]

public virtual DataView DataView
{
get
{
DataView t_DataView = m_DataTable.DefaultView;
if(m_Sort!=null)
{
t_DataView.Sort = this.m_Sort.SortExpression;
}
return t_DataView ;
}
set
{
m_DataTable = value.Table;
}
}
