title: Search anywhere in DataGridView
body: <p>I'm trying to write a program which will made a datagridview based on a text file. See code below.</p>
  
  <pre><code>private void Button1_Click(object sender, EventArgs e)
  {
      ls_datenTabelle.Clear();
      ls_datenTabelle.Columns.Clear();
  
      string kdstr = (comboBox1.SelectedItem.ToString());
      string fileName = "ls.txt";
      string fileName2 = kdstr + ".txt";
      string sourcePath = @"H:\import_directoy\customer\" + kdstr;
      string tempPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
      string dmitempPath = @"program_name\";
      string targetPath = Path.Combine(tempPath, dmitempPath);
  
      File.Delete(targetPath + "output");
  
      string sourceFileName = Path.Combine(sourcePath, fileName);
      string destFile = Path.Combine(targetPath, fileName2);
  
      Directory.CreateDirectory(targetPath);
  
      File.Copy(sourceFileName, destFile, overwrite: true);
  
      using (var output = File.Create(targetPath + "output"))
      {
          foreach (var file in new[] { "H:\\directoy1\\directoy2\\index.config", destFile })
          {
              using (var input = File.OpenRead(file))
              {
                  input.CopyTo(output);
              }
          }
      }
  
      string[] raw_text = File.ReadAllLines(targetPath + "output", Encoding.Default);
      string[] data_col = null;
      int x = 0;
      foreach (string text_line in raw_text)
      {
          data_col = text_line.Split(';');
  
          if (x == 0)
          {
              for (int i = 0; i &lt;= data_col.Count() - 1; i++)
              {
                  ls_datenTabelle.Columns.Add(data_col[i]);
              }
              x++;
          }
          else
          {
              ls_datenTabelle.Rows.Add(data_col);
          }
      }
  
      ls_dataGridView.DataSource = ls_datenTabelle;
      this.Controls.Add(ls_dataGridView);
      ls_dataGridView.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCells);
      ls_dataGridView.AllowUserToAddRows = false;
  }
  </code></pre>
  
  <p>Now I want to search all over this datatable/datagridview and I will show the rows if the search function found the searchvalue in any column.</p>
  
  <p>But I dodn't know how. The header of the table could change every day. So this code doesn't work for me:</p>
  
  <pre><code>public void findingValue(object sender, EventArgs e)
  {
      string searchValue = textBox1.Text;
  
      DataView data = ls_datenTabelle.DefaultView;
  
      ls_dataGridView.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
      data.RowFilter = string.Format("Name like '" + searchValue + "%'");
  }
  </code></pre>
  
  <p>The program will find only rows where the searchValue is in the "Name" column and not one of the other 18 (umknown) columns.</p>
