Hope that helps Hi everyone I have a DataGridView, inside of it is 2 columns, FullName and VoteCount. I want to refresh the DataGridView, for changes in my Database. How do I refresh the DatagridView without closing the form or clicking any button? Is it possible? , I think you have to re-fill the complete DataGridView.

I wish this helpful for you To Avoid adding same column many times, Check whether such column existing in the gridview or not, Before adding them. For checking this you can use the following code.
bool hasDeleteColumn=false;
foreach (DataGridViewColumn  item in dataGridView1.Columns)
    {
       if (item.GetType() == typeof(DataGridViewLinkColumn) && item.HeaderText=="Delete")
          {
              hasDeleteColumn = true;
              break;
          }
    }
if(!hasDeleteColumn)
  {
    // Adding columns if not existing
    DataGridViewLinkColumn Deletelink = new DataGridViewLinkColumn();
    Deletelink.UseColumnTextForLinkValue = true;
    Deletelink.HeaderText = "Delete";
    Deletelink.DataPropertyName = "lnkColumn";
    Deletelink.LinkBehavior = LinkBehavior.SystemDefault;
    Deletelink.Text = "Delete";
    dataGridView1.Columns.Add(Deletelink);
    dataGridView1.Refresh();
  }

it fixes the issue You have a field called dt somewhere in your form (not shown in the post), which you are refilling (hence adding the records to the previously loaded records) on each GetData call.
Remove the field and use something like this:
// Get Data
private DataTable GetData(string query)
{
    var dt = new DataTable();
    // ...
    return dt;
}
