dataGridView爲空

Question

我試圖從數據庫填充表格數據中的DataGridView。這是如何：

adpt = new System.Data.SqlClient.SqlDataAdapter(query, conn); 
DataTable dt = new DataTable(); 
adpt.Fill(dt); 

BindingSource bs = new BindingSource(); 
bs.DataSource = dt; 

dataGridView1.ReadOnly = true; 
dataGridView1.DataSource = bs; 
adpt.Update(dt); 

但我看到的只是空的DataGridView。有些人可以告訴我我錯了什麼或者我失蹤了嗎？

的基本功能，填補了數據的GridView低於，

void FillData() 
      { 
       // 1 
       // Open connection 
       using (SqlCeConnection c = new SqlCeConnection(
        Properties.Settings.Default.DataConnectionString)) 
       { 
        c.Open(); 
        // 2 
        // Create new DataAdapter 
        using (SqlCeDataAdapter a = new SqlCeDataAdapter(
         "SELECT * FROM Animals", c)) 
        { 
         // 3 
         // Use DataAdapter to fill DataTable 
         DataTable t = new DataTable(); 
         a.Fill(t); 
         // 4 
         // Render data onto the screen 
         dataGridView1.DataSource = t; 
        } 
       } 
      }
