When using TX Text Control in read-only mode, it might be required to display the page number of the currently visible page. In order to get the page number at the current input position, you just need to get the appropriate property from the [InputPosition](https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.inputposition.class.htm) object.

But when scrolling through the pages, the actual input position is not changed, so that this property can't be used to get the page number. But thanks to the flexible and powerful class library, it is very easy to retrieve the page number of the currently visible page.

In order to get the page number, we use the [LineCollection](https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.linecollection.class.htm) to get the line in the middle of the visible TextControl. TX Text Control automatically factors the current scroll location into the calculation, so that we just need to pass the half of the control size to the [GetItem](https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.linecollection.getitem.method.htm) method. It returns the [Line](https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.line.class.htm) object in the middle of the visible document part. And the *Line* object provides the according page number among other information.

```
private int GetPageAtScrollPosition()
{
    return textControl1.Lines.GetItem(
        new Point(0, textControl1.Height / 2)).Page;
}
```

We just need to update the information using the [VScroll](https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.textcontrol.onvscroll.method.htm) event:

```
private void textControl1_VScroll(object sender, EventArgs e)
{
    int iPageNumber = GetPageAtScrollPosition();

    Console.WriteLine("Page " +
        iPageNumber.ToString() +
        " of " +
        textControl1.Pages.ToString());

    Console.WriteLine("Section " +
        textControl1.GetPages()[iPageNumber].Section +
        " of " +
        textControl1.Sections.Count.ToString());
}
```
