dynamic button event in xml parsing - wpf

Question

i create a dynamic button(xmlparsingbuildbutton) during a buttonclick(xmlparsingbutton) event.
I did a xml parsing...once each xml target is parsed, they will create an individual checkbox. What i need is this: Create a dynamic button event(xmlparsingbuildbutton). During this dynamic button event, for every checkbox that is checked, they will append a text file by writing new lines into the text file. This gets confusing to me because right now i have a foreachloop embedded in the xmlparsingbutton event that creates all these checkboxes.
Right now, I've coded it in such a way that whenever i check the checkboxes, my append of file event will not fire therefore I created this "xmlparsingbuildbutton" to help fire the event.From my understanding, usually i would hard code buttonclickevent, however in this case the target value always change in the foreach loop and therefore it is not right to just merely hardcode the buttonclickevent.
So my question is how do i have this button event to be inside the foreach loop of the xmlparsing event button? Please clarify my doubts. Many thanks!
Here is my code:
private void xmlparsingButton_Click(object sender, RoutedEventArgs e)
{
XDocument xmlDoc = XDocument.Load(#"C:\Build.xml");
var abc = from target in xmlDoc.Descendants("target")
select (string)target.Attribute("if");

Grid.SetColumn(XmlparsingbuildButton, 4);
Grid.SetRow(XmlparsingbuildButton, 12);

XmlparsingbuildButton.Width = 51;
XmlparsingbuildButton.Content = "Build";
tab4grid.Children.Add(XmlparsingbuildButton);
foreach(string target in abc)
{
if (target != null && !Dictionarycheck.ContainsKey(target))
{
System.Windows.Controls.CheckBox chk = new System.Windows.Controls.CheckBox();
chk.Name = target+"CheckBox";
chk.Content = target;
Grid.SetColumn(chk, i); //sets column
Grid.SetRow(chk, j); //sets row
tab4grid.Children.Add(chk); //adds the control
Tabitem5.Visibility = Visibility.Visible;
i++;
if (i == 4)
{
j++;
i = 0;
}
if (chk.IsChecked == true)
{
using (var writer = File.AppendText(#"c:\testing.txt"))
{
writer.WriteLine(target);
}
}
}
}
Tabitem5.Visibility = Visibility.Visible;
Tabcontrol1.SelectedIndex = 4;
}

I have to admit, I have problems understanding your problem. If I get it right, you're trying to do the following:
Parse a Xml document ("C:\Build.xml") with (roughly) this format:
targets>
target if="aaa" />
target if="bbb" />
/targets>
Create a CheckBox for each target tag with if- attribute set
Check the CheckBox containing the string you want to use
Click a button to append the checked strings to a text file ("c:\testing.txt")
If this is correct, then I think your solution won't do that. I not sure if I can understand what you are trying to do in your code. The way you set up the comboboxes they will never be checked the time you use your writer.
How about this:
Use a StackPanel (stackPanel1) instead of a grid. That way you don't have to create all the row definitions. (Ok, I have to admit, I don't know what all these columns are for)
Create a simple logic for a button to append the checked ComboBoxes to the file
code:
private void xmlparsingButton_Click(object sender, RoutedEventArgs e)
{
stackPanel1.Children.Clear();
XDocument xmlDoc = XDocument.Load(#"C:\Build.xml");
var abc = from target in xmlDoc.Descendants("target")
select (string) target.Attribute("if");
foreach (string target in abc)
{
if (target != null)
{
System.Windows.Controls.CheckBox chk = new System.Windows.Controls.CheckBox();
chk.Name = target + "CheckBox";
chk.Content = target;
chk.Tag = target;
stackPanel1.Children.Add(chk);
}
}
}
private void btnAppendToTextFile_Click(object sender, RoutedEventArgs e)
{
using (var writer = File.AppendText(#"c:\testing.txt"))
{
foreach (var child in stackPanel1.Children)
{
if ((child is CheckBox) && ((CheckBox) child).IsChecked.Value)
{
writer.WriteLine(((CheckBox)child).Tag);
}
}
}
}
I hope this helps you with your problem.
