c# Search data grid column for top 10 repeaters

Question

I am sure this has been asked before but I cant find an example.

 

I have a Winform and want to search 1 column for the Top 10 repeaters. Can you show some examples of doing such?

 

This is one of my search function

private void btn_SearchPart_Click(object sender, EventArgs e)
{
    string Part = textBox3.Text.ToString();
    if (Part != "")
    {
         string queryString = "SELECT SheetID, Today, Part, Type FROM LC,movietype WHERE movietype.typeID = ILC.typeID AND LC.Part LIKE '" + Part + "%'";
          loadDataGrid(queryString);
          textBox3.Clear();
    }
}
