绑定网格中的错误:网格视图未绑定? [英] Error in Bind Grid: Grid view is not binding ?

问题描述

private void grid_view()
        {
            string s = System.Configuration.ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString;
            string sel = "select * from TableName";
            SqlConnection con = new SqlConnection(s);
            SqlCommand cmd = new SqlCommand(sel, con);
            SqlDataAdapter sda = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            sda.Fill(ds);
            dataGridView1.DataSource = ds;
            dataGridView1.DataBind();
       }

运行代码时出现此错误

"
``System.Windows.Forms.DataGridView''不包含``DataBind''的定义，并且没有接受类型为``System.Windows.Forms.DataGridView''的第一个参数的扩展方法``DataBind''找到(是否缺少using指令或程序集引用?)
"

i have this error when i run my code

"
''System.Windows.Forms.DataGridView'' does not contain a definition for ''DataBind'' and no extension method ''DataBind'' accepting a first argument of type ''System.Windows.Forms.DataGridView'' could be found (are you missing a using directive or an assembly reference?)
"

推荐答案

设置数据源时，网格应显示数据.因此，只需注释掉最后一行.

设置数据源时，请使用数据表，而不要使用数据集.例如:

When you set the datasource the grid should show the data. So just comment out the last line.

When setting the datasource, instead of using a dataset, use the datatable. For example:

dataGridView1.DataSource = ds.Tables[0];

如果仍然看不到网格中的任何内容，请在代码中放置一个断点，并检查数据表中是否确实有行.

If you''re still not seeing anything in the grid, put a breakpoint in your code and check that there actually are rows in your datatable.
