推荐答案

如果您只想显示过滤的行，请使用 BindingSource.Filter 属性.这是 MSDN

if you want to display only the filtered rows use BindingSource.Filter property. Here is a good sample in MSDN

bindingSource.Filter = "columnname = 'value'";

private void button1_Click(object sender, EventArgs e)
{
    string searchValue = textBox1.Text;

     dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
     bindingSource.Filter = string.Format("{0} = '{1}'","YourColumnName", searchValue );
     //here you can do selection if you need
}

要删除过滤器，请使用以下内容

---

To remove filter use the following

bindingSource.RemoveFilter();

或

bindingSource.Filter = null;
