Hi,
How to start to edit listview items programatically, like in explorer
when user right click on a file the select Rename?
I know how to make items editable with a click, but I want to add a
button / right click menu for this too
Thanks

I use:
private void DoEditItem()
{
// Only handle if 1 item selected
JLVItemEx lvItem = GetSelectedListViewItem();
if (lvItem == null)
{
FireMessageSender(this, "Please Select One Object To Edit", true);
return;
}
m_EditingLabel = true;
lvItem.BeginEdit();
}
private JLVItemEx GetSelectedListViewItem()
{
if (this.SelectedItems.Count != 1)
return null;
return (JLVItemEx)this.SelectedItems[0];
}
The key things being to ensure you have a selected ListViewItem and call
lvItem.BeginEdit();
You need to switch JLVItemEx for ListViewItem if you are using standard
ListViewItems.
Yo need to trap AfterLabelEdit if you want to validate the new text/name.

Thanks for answer.
It worked for me just by using BeginEdit (that was the method I was
looking for)
I don't understand what is the other code you wrote. What is it good
for? And what is JLVItemEx
Thanks

JLVItemEx is one of my classes based on a ListViewItem, it has additional
properties like Path, FileType etc.
The code is split into small functions in my library and I just copied and
pasted it.
For instance GetSelectedListViewItem() is a function I use all the time so
having it in a function means I just have to call the function and know I
will either get a valid ListViewItem or null returned, it saves a lot of
repetitive code.
The same with DoEditItem() - it can be called from a menu, the F2 key or
even from outside the file it is in.

Thanks, I thought it was some NET class I wasn't aware of.
