Its Better for you To use case in your dataBase Query
CREATE procedure Procedurename
(
@Query varchar(500)
)
as
declare @CaseSyntax varchar(500)
set @CaseSyntax='case CandidateDetails.IsFresher
when 0 then ''Fresher''
when 1 then ''Experience''
end as Isfresher '
exec ('select InterviewCategories.Category,CandidateDetails.CandidateID,CandidateDetails.FirstName+CandidateDetails.LastName as Name,
CandidateDetails.ContactNo,CandidateDetails.Email,'+ @CaseSyntax +'
,
Qualification.QualificationName,CONVERT(CHAR(10),CandidateDetails.CreatedOn, 105) as Date from CandidateDetails
inner join InterviewCategories on CandidateDetails.InterviewCategoryId = InterviewCategories.InterviewCategoryID
inner join Qualification on CandidateDetails.QualificationID = Qualification.QualificationId '+@Query)
It will give you result as Required and then
and then in aspx Page You simply have to write
<asp:HyperLink ID="hyp_Isfresher" NavigateUrl='<%#"~/Admin/CandidateExperienceDetails.aspx?Id="+Eval("CandidateID") %>'
Text='<%#Eval("IsFresher")%>' runat="server"></asp:HyperLink>
