使用gridview數據綁定後的條件更改列值

Question

我使用join從三個表格中顯示數據Gridview。 但我想改變使用條件的領域。

我把我的「狀態」保持爲「1」和「0」。 對於「1」，我想顯示「選定」，對於「0」，我想顯示「拒絕」。

下面是我的代碼：

void databind() 
{ 
    string CS = ConfigurationManager.ConnectionStrings["myConnectionString"].ConnectionString; 
    using (SqlConnection con = new SqlConnection(CS)) 
    { 
     con.Open(); 
     SqlCommand cmd = new SqlCommand("select a.applicant_id as 'Applicant ID',a.applicant_name as 'Name',a.status as 'Status',b.staff_Name as 'Reviewed by',c.course_name as 'Course' from tblApplicant a left outer join tblStaff b on a.staff_id=b.staff_id left outer join tblCourse c on a.course_id=c.course_id", con); 
     SqlDataReader dr = cmd.ExecuteReader(); 
     GridView1.DataSource = dr; 
     GridView1.DataBind(); 
    } 
} 

Answer 1

使用與case when這條線

SqlCommand cmd = new SqlCommand("select a.applicant_id as 'Applicant ID',a.applicant_name as 'Name',case when a.status=0 then 'Rejected' else 'Selected' end as 'Status',b.staff_Name as 'Reviewed by',c.course_name as 'Course' from tblApplicant a left outer join tblStaff b on a.staff_id=b.staff_id left outer join tblCourse c on a.course_id=c.course_id", con);
