Using a Treeview with Checkboxes

Question

I have treeView that has several Nodes like this

Question 1 Question 2 Question 3 Question 4

Inside each of those node there are 4 checkboxes - Answer A, Answer B, Answer C, Answer D, depending on whichever checkbox is clicked the text of a Node will change to Question1 - A,B,C,D. The answer to the question could mean all,one,two,three or none of the checkboxes are clicked. What im trying to do is remove the letter if a checkbox is unchecked My Code:

private void ckbAnswerA_CheckedChanged(object sender, EventArgs e) { updateAnswerA(); } void updateAnswerA() { var words = new List<string>(); if (ckbOption1.Checked) { words.Add("A,"); treeView1.SelectedNode.Text += string.Join(" ", words); }

Etc for the other checkBoxes...

The Code above works fine when selecting a checkBoxes but not when deselecting

I just noticed something that wasn't in the previous question, you are adding the text after each check whereas it should be done after all boxes have been checked! — Alfie Goodacre

ok, do you mean putting all the If Statements in one method? — AndroidAL

I manually way, I hope you get the idea.

private void ckbAnswerA_CheckedChanged(object sender, EventArgs e) { if (ckbAnswerA.Checked) { updateAnswerA(true); } else { updateAnswerA(false); } } private void updateAnswerA(bool flag) { if(flag) { var words = new List<string>(); words.Add("A,"); treeView1.SelectedNode.Text += string.Join(" ", words); } else { string update = treeView1.SelectedNode.Text; update = update.Replace("A,", ""); treeView1.SelectedNode.Text = update; } }
