DataGridView綁定不起作用

Question

我正在使用winforms項目，並且我在Form_Load方法中有以下代碼。但它不起作用。誰能幫我？

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Sella.Properties.Settings.Database1ConnectionString1"].ConnectionString); 
// A SqlCommand object is used to execute the SQL commands. 
SqlCommand scmd = new SqlCommand("Select * From CustCalls", conn); 
// A SqlDataAdapter uses the SqlCommand object to fill a DataSet. 
SqlDataAdapter sda = new SqlDataAdapter(scmd); 
// Create and Fill a new DataSet. 
DataSet ds = new DataSet(); 
sda.Fill(ds); 

dataGridView1.DataSource = ds; 

Answer 1

嘗試採購直接到數據集中的表：

dataGridView1.DataSource = ds.Tables[0]; 

Answer 2

SqlDataAdapter sda = new SqlDataAdapter(scmd, conn); 

dataTable dt = new DataTable(); 

sda.Fill(dt); 

dataGridView1.DataSource = dt;
