DataGridView绑定不起作用

本文关键字:不起作用 绑定 DataGridView | 更新日期: 2023-09-27 18:20:39

我正在处理一个winforms项目,在Form_Load方法中有以下代码。但它不起作用。有人能帮我吗?

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;

DataGridView绑定不起作用

尝试直接查找数据集中的表:

dataGridView1.DataSource = ds.Tables[0];
SqlDataAdapter sda = new SqlDataAdapter(scmd, conn);
dataTable dt = new DataTable();
sda.Fill(dt);
dataGridView1.DataSource = dt;
