Thread searching a DataGridView Control

As my people are entering data into a textbox, I want to bring the most relevant row of data into view on my DataGridView control.

I do this now, but I can't do it in a thread since it is part of the Form and not thread safe.

How can I search a DataGridView's data from within a thread?

Example:

int FindRow(string textBoxValue) {
  for (int i = 0; i < DataGridView1.Rows.Count; i++) {
    if (DataGridView1.Rows[i].Cells[x].Value.ToString() == textBoxValue) {
      return DataGridView1.Rows[i].Index;
    }
  }
  return 0;
}

The above is not thread safe, of course.

I don't want to pass the entire DataGridView object to a thread as a parameter because it can be rather large and our clerks enter data pretty fast!

Those techniques are similar to what I started with. The problem was that will the amount of data I had, the GUI was responding slower than our clerks were inputting the text.
I found a solution that works for me by using the Binding Source's Find method in this article: BindingSource.Find by partial string? Hopefully others find this helpful as well.
Thanks for your help!

Hi Amit,
I neglected to mention: This is a Windows Application, so javascript not an option.

hi friend,

if you are working on asp.net web application then you can achieve it using javascript and it'll be more efficient and performance promised rather then using Threads.
