Not entirely clear on exactly what you're asking, but if you mean how to delete selected item in Listbox, do like this:

index = ListBox.GetSelected("ListBox1");

if (index ~= nil) then
 ListBox.DeleteItem("ListBox1", index[1]);
end

...And if your Listbox is multi-select enabled (ie. if you wish to select and delete multiple items from it), then:

index = ListBox.GetSelected("ListBox1");

if (index ~= nil) then
    for k, v in pairs (index) do
      ListBox.DeleteItem("ListBox1", index[1]);
    end
end

Hello bio thanks for your response.. i want to create a right click on my listbox that there is a menu with delete..
Example on listbox there is 3 item if i want to delete the 2nd one i need to right click and select delete..

Okay, I get you. Have a look at the attached "right click menu" APZ. It's not exactly what you're after - but should steer you in the right direction. With some mods to the menu code, you should be able to make some progress.

Thank you so much i never come up with this idea.. Thank you Bio you really help a knob like me...
what i have now is i click on listbox and press delete on keyboard to delete selected listbox...

No problem. Had some time to kill this morning - so modded the above apz to what you're seeking. Have a look at the newly attached example - I think this is more in line with what you're after, yeah?

Hello bio.. can i get some help again with this code?
i have a text file that will load to the listbox.


when i delete specific entry on listbox how to delete it also on the text file?


Example on Textfile i have:

1. America
2. Japan
3. Korea

On my lisbox i want to delete the Japan also it will delete on my textfile..


Thanks..

Yep, here's one way to go about it - see attached. Just a matter of reading your textfile data into table and referencing from there.
.
Not sure if this example is completely bug-free. Too tired to check properly right now and starting to hallucinate coding elves, again. (Should about do the trick, though).

Thanks Bio it works but the problem if the lisbox is on Sort it will delete incorrect line of the textbox.

[telco]

i mean it will delete incorrect line from the textfile.. but it sort is not check it works fine..

[BioHazard]

That's a one-line fix. Use the Table.Sort() function. Place this immediately after Line-5 on the Load Listbox button, so that the data gets sorted right after it gets read to table from textfile:

Table.Sort(tMyText, nil);

That way the data is sorted regardless of whether your Listbox has the sort-function checked. Fix is attached.

The alternative would be to do it at Line-18 on the Delete from Listbox button, so that the tMyText variable containing the table is sorted prior to overwriting the textfile.
