BackgroundWorker backgroundWorker1 = new BackgroundWorker(); 
backgroundWorker1.DoWork += BackgroundWorker1_DoWork;
 backgroundWorker1.RunWorkerAsync();
   
private void BackgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    Delegate d = new UpdateControlsDelegate(UpdateGrid);
    //To check whether the call is from the UI thread.
    if(this.gridControl1.InvokeRequired)
    {
        this.gridControl1.Invoke(d);
    }
}
 
private void UpdateGrid()
{
    Thread.Sleep(1000);

}

public void FormatGrid()
{
    for (int i = 1; i <= 100; i++)
    {
        //Applying back color to the grid.
        gridControl1[i, 1].BackColor = Color.Red;

Dim backgroundWorker1 As New BackgroundWorker()
AddHandler BackgroundWorker1.DoWork, AddressOf BackgroundWorker1_DoWork
BackgroundWorker1.RunWorkerAsync()
 
Private Sub BackgroundWorker1_DoWork(sender As Object, e As DoWorkEventArgs)
    Dim d As System.Delegate = New UpdateControlsDelegate(AddressOf UpdateGrid)
    'To check whether the call is from the UI thread.
    If Me.gridControl1.InvokeRequired Then
        Me.gridControl1.Invoke(d)
    End If
End Sub
 
Private Sub UpdateGrid()

End Sub

Public Sub FormatGrid()
