I have a filtered DataView and I wanted to search it using different keys that was used for sorting.
Ther is no function out-of-the-box, so I created a helper method
public static DataView CloneDataView(DataView vwSource,string newSort)
{
return new DataView(vwSource.Table ,vwSource.RowFilter,newSort,vwSource.RowState) ;
}
Another function to create new DataView with extra filter:
public static DataView NewDataViewWithExtraFilter(DataView vwSource, string newFilter)
{
string sFilter = vwSource.RowFilter;
if (String.IsNullOrEmpty(sFilter))
{
sFilter = newFilter;
}
else
{
sFilter += String.Format(" and ( {0} )", newFilter);
}
DataView newDV = new DataView(vwSource.Table, sFilter, vwSource.Sort, vwSource.RowStateFilter);
return newDV;
}
