Selecting an item in a checked listview when form loads

[Lucy]

I have a checked listview on my windows form. When the form loads I have code where a specific item in the listview is selected: listView1.Items[1].Selected = true; But I also have a selected index changed event. In this event I go through all listview items and set their checked property to false and then check the item that has just been selected: foreach (ListViewItem lvi in listView1.Items) { lvi.Checked = false; } listView1.SelectedItems[0].Checked = true; These two pieces of code do not work together. If I comment one section of code, then no errors occur and vis versa but when both pieces of code are not commented out I get the following error at run time: An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll How do I solve my problem as both pieces of code are needed.

How about only assigning the SelectedIndexChanged event after making the initial item selected.

[Lucy]

So the SelectIndexChanged event would fire when the user selects an item? How would I do that? Lucy

checked listview

Haven't heard of it. Is it a ListView with CheckBoxes or CheckedListBox?

I will use Google before asking dumb questions

It is a listview with checkboxes. Lucy

Well....I will just give you an idea. The StackOverflow exception is because in the CheckChanged event you change the checked property of the listview items, thus this generating another checkchanged event, and so you enter in a infinite loop, which at a certain moment fills the system's stack and the program stops. To avoid this situation you should check if the checkedchanged event has been triggered by the user or by your code. I situation almost like these I used to use a boolean value which is set to true if I change the checked property of an item, or false if the user checks the item, and in the event handler method do whatever you need depending on the value. It's just an idea to work around this problem...maybe you'll find another one. Hope it helps.

Thank you for your help. Yes I noticed that both of these events were fired many times whilst debugging. I now understand a bit more about stacks. I will try and use boolean values to solve my problem. Lucy
