如何仅显示过滤后的数据

Question

大家早上好。我想在我的表中只显示过滤记录，这怎么可能我当前的代码显示突出显示的过滤记录和其他非过滤记录。这怎么可能。

private void textBox2_TextChanged(object sender, EventArgs e)
   {
       try
       {
           this.dataGridView1.ClearSelection();
           foreach (DataGridViewRow r in this.dataGridView1.Rows)
           {
               if (r.Cells[1].Value != null)
               {
                   if ((r.Cells[1].Value).ToString().StartsWith(this.textBox2.Text.Trim()))
                   {
                       this.dataGridView1.Rows[r.Index].Selected = true;
                   }
               }
           }
       }
       catch (Exception ex)
       {
           MessageBox.Show(ex.ToString());
        }
    } 
private void dataGridView1_DataBindingComplete(object sender,DataGridViewBindingCompleteEventArgs e)
    {
        dataGridView1.ClearSelection();
    }

Yorye Nathan 的评论是正确的

try
            {
                foreach (DataGridViewRow r in this.dataGridView1.Rows)
                {
                    if (r.Cells[0].Value != null)
                    {
                        if ((r.Cells[0].Value).ToString().StartsWith(this.textBox1.Text.Trim()) && textBox1.Text.Trim().Length > 0)
                        { 
                            this.dataGridView1.Rows[r.Index].Visible = false;
                        }
                        else
                        {
                            this.dataGridView1.Rows[r.Index].Visible = true;
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

假设输入类似于

this.dataGridView1.Columns.Add("Text", "Text");
            this.dataGridView1.Rows.Add("five");
            this.dataGridView1.Rows.Add("six");
            this.dataGridView1.Rows.Add("seven");
            this.dataGridView1.Rows.Add("eight");
            this.dataGridView1.Rows.Add("nine");
