Question

I want to put a search option in DataGridView, i.e., User types the string or int in TextBox and similar records the DataGridView should be highlighted. I tried it using KeyPress event but didn’t work.

  if (Char.IsLetter(e.KeyChar))
  {
     for (int i = 0; i < (dgemployee.Rows.Count); i++)
     {
         if (dgemployee.Rows[i].Cells["Employee"].Value.ToString().
                    StartsWith(e.KeyChar.ToString(), true, 
                    CultureInfo.InvariantCulture))
         {
             dgemployee.Rows[i].Cells[0].Selected = true;
             return;                     
         }
      }

Actually, I need to search the whole DataGridView, not only one column and row. So any best solution?

If your DataGridView is bound to a DataTable or a DataView, you can do this:

Create a BindingSource and make BindingSource.DataSource the Datatable or DataView that your DGV is currently using. Then set your DataGridView.DataSource to the BindingSource. Then you can use the BindingSource.Filter property to query your datasource by setting the BindingSource.Filterto your query string which will automatically filter the DGV. You can find the syntax here – it is very similar to basic SQL queries, except you can only use wild cards on the beginning and end of the string.
