In Some conditions we need to apply some condition on dataset in code behind. To apply condition on dataset we need to convert dataaset in Dataview.

Steps:
Create a object of dataview
Put dataset to data view
Apply rowfilter

We will take an example of Apply multiple conditions on dataview

Suppose we want to show only those rows which have status=Active or Inactive. We will apply below code

ds - is dataset having rows
dlTour is data list

				
 DataView dv = new DataView();
 dv = ds.Tables[0].DefaultView;
 dv.RowFilter = " Status='Active' or Status='InActive'";
 dlTour.DataSource = dv;
