Add Items in combo box at runtime

[song403]

In my program, I want to add int "34" "43","17"...... and let user choose one of them from combo box. How can I add such items in combo box at runtime. Create a property node "String[]"? I try that but its display is "3443". I wanna to display like "34"

                                                                                                                                                                 17

Did you wire an array of 3 elements to the property node? A string with linefeed wont do.

In my program, I fetch data one by one. first, I fetch 34, second, I fetch 43 and so on. So I want to add item one by one also. but  I can not link string to string[]. So how can I do?

Hi song,

collect your strings in an array and wire the array to that property node.

That's how it works!

Just a small tip.

Adding Strings[] is probably not ideal unless Values = strings property is true and I can't tell if it is from the OPs question!  Better practice is to use the Strings and Values[] property and add both the string and the value

One more question. How can I clear items from combo box when my program start up. use another property?

Hi song,

use the very same property - and wire an array only containing the strings/values you need…

If you want to clear the contents of combo box, just create array constant for the same property node and do not include any element in that array. (empty array)
