Combo Text Box with Search Option

[Dev2018]

Hello All, 

I had the opportunity to experiment on this VI -  https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000fzUTSAY&l=en-CA. This VI works as expected and would require more features to build on based on my requirement. Need your expertise. 

The drop down under the combo box, list all the names stored in the string history.

Is there a way to add filter to list string text as google search does ? For example; if I stores names like Peter, Peter Pan, Peter Ram and Ela. When I type "P", I want the combo box to list only the names stored under "P". Just the way our Google Search works. 

Can someone help me with this ?

Take a look at QControl toolkit.

What is "this"?  Use the quote button when responding to a particular person so others know what you are responding about.

You may also try replacing the search array with a Match Regular Expression node.

Hello, 

Please see the attached code and the output displayed in the Image. 

I need your help in modifying the code. When I add name to the Operator Name Combo Box, the history is getting added. When I type letter "R" I want the drop down to list only the words/string that starts with letter "R". Based on letters we type, I want the drop down to list words based on search. 

Can someone help me. 

Thank you.

You will want to right click the control and set it to "Update value while typing". Use a NewVal event to catch the new entry, and use Match Regular Expression to filter through the list of possible inputs, then set the ComboBox values to those. Alternatively, you could do an "autocomplete" style where it picks the nearest one and fills out the box, but moves the cursor back to where you were typing, allowing you to continue adding letters for the autocomplete.

Can you provide me the VI with your changes incorporated ?
