AutoCompleteCustomSource Property Textbox in VB.Net
AutoCompleteCustomSource Property Textbox in VB.Net.
In this tutorial, you will learn how to use the AutoCompleteCustomSource Property Textbox in VB.Net.
AutoCompleteCustomSource Property is a collection type property where you can store data from it and can easily be called from your textbox object.
It serves as a suggestion or a guide of words where it depends on the user’s typed characters.
First, let’s create a Visual Basic project and drag a textbox object. Here’s the sample design:
Next, we go to the textbox property and modify its property for us to use the AutoCompleteCustomSource property.
Steps in Achieving the Tutorial
Follow these steps carefully:
- Set AutoCompleteMode to “Suggest” – this will let your textbox suggest words from the typed text of the user.
- Set AutoCompleteSource to “CustomSource” – this will let your textbox know where to get its auto complete source.
- Next, we are going to put string values to our AutoCompleteCustomSource. Let’s add this following values:
Amber Ambulance Apple Archer Bash Bend Block Brick Bunker Call Cat Cherry Chunk
or you can refer to this sample image:
Let’s run our system. First, type letter A and see the results. Here’s my sample results:
Notice that when you typed letter A, the textbox automatically suggest string values based on your stored strings in the AutoCompleteCustomSource.
Now, erase the letter A and type letter B. Your expected results should be like this:
You can see that it suggests string values based from your stored strings that starts with letter B.

Frequently Asked Questions
How does this VB.NET property management system work?
Property master (units, owners, tenants), lease agreements, rent collection, maintenance requests, utility billing, expense tracking.
What Visual Studio and SQL Server versions does this VB.NET project require?
Most projects use VB.NET WinForms on .NET Framework 4.5+ with SQL Server 2012 Express or higher. To run: install Visual Studio 2019 / 2022 (Community is free) with the ‘Desktop development with .NET’ workload, install SQL Server Express + SSMS, open the .sln file, build, run.
How do I set up the database for this VB.NET project?
Open SQL Server Management Studio (SSMS) and connect to your SQL Server (e.g. localhost\SQLEXPRESS). Right-click Databases, choose Restore Database OR New Database then import the included .sql script. Update the connection string in App.config (or in code-behind Module) with your server name + credentials. Rebuild and run.
Can I use this VB.NET project for a BSIT capstone or thesis?
Yes, VB.NET is one of the most accepted languages by Philippine BSIT panels. Extend it: add role-based access (admin/staff/customer login redirect), Crystal Reports or RDLC reports, dashboards with Chart control, audit log, multi-branch support. Pair with Chapter 1-5 documentation matching your panel’s rubric.
Why am I getting ‘connection error’ or ‘cannot find SQL Server’?
Three common VB.NET issues: (1) Connection error: SQL Server isn’t running. Open SQL Server Configuration Manager and verify SQL Server (SQLEXPRESS) service is started. (2) Wrong server name in connection string. Try .\SQLEXPRESS, (local)\SQLEXPRESS, or your machine name. (3) Login failed: SQL Server is set to ‘Windows-only’ authentication. Switch to Mixed Mode in SSMS Server Properties, Security.
