Help with creating a filter in a data grid!!

I want to create a filter to filter text in a datagrid as i type in a text box. I have two text boxes, one to filter in text that i type and one to filter out text that i type. I want the data grid to update as i type into either one of the textboxes. Here is some of my code:


private void txtFilterIn_TextChanged(object sender, TextChangedEventArgs e)
{
DataView dv = dgPortStatus.DataContext as DataView;
if (dv != null)
{
if (dv.Table.TableName.ToUpper() == "PORTSTATUS")
{
FilterDataGrid(txtFilterIn.Text, txtFilterOut.Text, _dicPortStatus[cmbGroups.SelectedItem.ToString()]);
}
}

List<QuarantineView> qvList = dgPortStatus.DataContext as List<QuarantineView>;
if (qvList != null)
{
//Filter on quarantine manager
FilterQuarantineViewList(qvList);
}
}

private void btnFilterInClear_Click(object sender, RoutedEventArgs e)
{
txtFilterIn.Clear();
}

private void txtFilterOut_TextChanged(object sender, TextChangedEventArgs e)
{
DataView dv = dgPortStatus.DataContext as DataView;
if (dv != null)
{
if (dv.Table.TableName.ToUpper() == "PORTSTATUS")
{
FilterDataGrid(txtFilterIn.Text, txtFilterOut.Text, _dicPortStatus[cmbGroups.SelectedItem.ToString()]);
}
}

List<QuarantineView> qvList = dgPortStatus.DataContext as List<QuarantineView>;
if (qvList != null)
{
//Filter on Quarantine Manager
FilterQuarantineViewList(qvList);
}
}

private void btnFilterOutClear_Click(object sender, RoutedEventArgs e)
{
txtFilterOut.Clear();
}

//And this method is where my filter needs to go:

private void FilterQuarantineViewList(List<QuarantineView> qvList)
{


}

edit your post and add CODE tags... then we'll see what can be done

Sorry, It will not let me edit my post.
