public void getfilesandfolders()     {         using (irepentities dbcontext = new irepentities())         {              string vchartempfilelocation = (from in dbcontext.tbl_applicationsetting                                             a.vcharkey == "vchartempfilelocation"                                             select a).single().vcharvalue;              datatable gridviewsource = displayfilesingridview();             datarow gridviewrow;              //get folders or directories , add in table               directoryinfo directory = new directoryinfo(vchartempfilelocation);             directoryinfo[] subdirectories = directory.getdirectories();              foreach (directoryinfo dirinfo in subdirectories)             {                 gridviewrow = gridviewsource.newrow();                 gridviewrow["claim"] = ddlclaimnumber.selecteditem;                 gridviewrow["name"] = dirinfo.name;                 dynamic newlink = new hyperlinkfield();                  newlink = vchartempfilelocation + dirinfo.name;                  gridviewrow["link"] = newlink;                 gridviewrow["application"] = chkapplicationtype.selecteditem;                  gridviewsource.rows.add(gridviewrow);             }                 //get files in directories                fileinfo[] files = directory.getfiles("*.*", searchoption.alldirectories);             foreach (fileinfo fileinfo in files)             {                 gridviewrow = gridviewsource.newrow();                 gridviewrow["claim"] = ddlclaimnumber.selecteditem;                 gridviewrow["name"] = fileinfo.name;                 dynamic newlink = new hyperlinkfield();                  newlink = vchartempfilelocation + fileinfo.name;                  gridviewrow["link"] = newlink;                 gridviewrow["application"] = chkapplicationtype.selecteditem;                                                     gridviewsource.rows.add(gridviewrow);             }                                       gvbatchdetails.datasource = gridviewsource;             gvbatchdetails.databind();          }      }     private datatable displayfilesingridview()     {         datatable dtgridviewsource = new datatable();         dtgridviewsource.columns.add(new datacolumn("claim", typeof(system.string)));         dtgridviewsource.columns.add(new datacolumn("name", typeof(system.string)));         dtgridviewsource.columns.add(new datacolumn("application", typeof(system.string)));         dtgridviewsource.columns.add(new datacolumn("link", typeof(system.string)));          return dtgridviewsource;     }   } 

instead of building gridview manually, create datasource can bind to.

first create custom class hold details:

public class fileorfolderdetail {     public string claim{get;set;}     public string name{get;set;}     public string link{get;set'}     public string application{get;set;} } 

next, create list of new class:

var fileorfolderdetails = new list<fileorfolderdetail>(); 

at point, go through 2 loops you're doing, create new fileorfolderdetail objects , add them list.

finally, bind gridview fileorfolderdetails, , set hyperlinkfield in aspx use link datanavigateurl.

let's start there , can tweak necessary.
