根據用戶選擇顯示gridview列

Question

我有一個Gridview，並希望根據用戶選擇動態製作標題。

如何創建從用戶中選擇的標題。

Answer 1

DataTable會幫你實現。請按照下面的代碼

DataClassesDataContext db = new DataClassesDataContext(); 

protected DataTable GetDataSource() 
{ 
DataTable dt = new DataTable(); 

var questions = db.ExecuteQuery<string>("select question from quiz where quizid is 123").ToList(); 

// Header implementation 
int count = 0; 
foreach (var question in questions) 
{ 
    DataColumn dc = new DataColumn(question); 
    dt.Columns.Add(dc); 
    count++; 
} 

// Rows implementation here 
DataRow row = dt.NewRow(); 
... 
dt.Rows.Add(row); 

return dt; 
} 


protected void Page_Load(object sender, EventArgs e) 
{ 
GridView1.DataSource = GetDataSource(); 
GridView1.DataBind(); 
}
