How to display checkbox selected row of gridview in another page

For this, add the selected rows values in a new data table or data set that is common to all pages
then bind the data set values to grid view in another page

Eg:

DataTable dt = new DataTable();  //Dynamic data table 
DataRow dr;

dt.Columns.Add(new DataColumn("ColumnName1"));  // ColumnName1 is select 
dt.Columns.Add(new DataColumn("ColumnName2"));
dt.Columns.Add(new DataColumn("ColumnName3"));

Then bind this data table in grid view in next page
