I successfully imported Background value from XML file to Textbox txtInputFileT, however I still need to import value of X0 into NumericUpDown NumericUpDownX0 and value of cmbFontSize0 to Combobox ComboboxX0

Not sure how to structure it within the while and if statements ?

My XML file:

<?xml version="1.0"?>
<ArrayOfXMLSaveClass xmlns:xsi="http://www.w3.org/2001/XMLSchema">
  <XMLSaveClass>

    <Background>D:\Temp\100 Hacks for Every Occasion.pdf</Background>
    <X0>4.5</X0>
    <cmbFontSize0>12</cmbFontSize0>
  
</XMLSaveClass>
</ArrayOfXMLSaveClass>

What I have tried:

        private void button4_Click(object sender, EventArgs e)
        {           
            var dialog = new OpenFileDialog
            {
                Filter = "XML (*.xml)|*.xml"
            };

            if (dialog.ShowDialog() != DialogResult.OK)
            return;

            var streamX = dialog.OpenFile();                   
            var readerX = XmlReader.Create(streamX);


            while (readerX.Read())
            {
                if (readerX.NodeType != XmlNodeType.Element || readerX.Name != "Background")
                    continue;

                var L01 = readerX.ReadElementContentAsString();

                    try
                    {                        
                        txtInputFileT.Text = L01;
                        XX.Enabled = true;
                        YY.Enabled = true;
                        UpdatePreview();
                    }
                    catch (Exception Er3)
                    {
                    MessageBox.Show(Er3.Message);
                    }
					
            }
         }

Load your values into an object / properties and bind to that; don't stuff controls directly ... because of the issues you're encountering.

May be it's not optimal but that's the best I could do !

var streamX02 = dialog.OpenFile();
var streamX03 = dialog.OpenFile();

var readerX02 = XmlReader.Create(streamX02);
var readerX03 = XmlReader.Create(streamX03);

while (readerX02.Read())
{
    if (readerX02.NodeType != XmlNodeType.Element || readerX02.Name != "txtInputFile0")
        continue;
    var L02 = readerX02.ReadElementContentAsString();
    try
    {
        txtInputFile0.Text = L02;
        //UpdatePreview();
    }
    catch (Exception Er3)
    {
        //Block of code to handle errors
    }
}

while (readerX03.Read())
{
    if (readerX03.NodeType != XmlNodeType.Element || readerX03.Name != "cmbFont0")
        continue;
    var L03 = readerX03.ReadElementContentAsString();
    try
    {
        cmbFont0.Text = L03;
        //UpdatePreview();
    }
    catch (Exception Er3)
    {
        //Block of code to handle errors
    }
}
