Please, I'm using vb.net ultimate 2013 and I have about 15 comboboxes being populated with data at runtime.
Now, I used a "for loop"to add autocomplete feature to the comboboxes and it takes a longer time to load the form as a result of the "for loop", looping through each combo box to add the autocomplete feature. I thought of a binding source but how to implement it becomes a problem. Is there any quick way to to add the auto complete feature at runtime? That's my code below.
