Hi All,

I am working on a internal project and need to load or suggest data from database. I have to do this using Text box only (not with Combo box) As i cannot pre load data and attach as data in DB is very high in number as it is 1.7 million rows. I need to do it on Text_Changed of text box Dynamically. However, windows default (Text Box Auto Complete) is helping me with this. But the width of loading suggestions are restricting to Text box length. I need this list width should be at least 600 as data from database is long of 200 characters. I need to show at least 100 chars.

I am using

C# winforms UI.
.net 2.0 framework.
SQL Compact DB 4.0

Looking forward for help from beloved coders.

What I have tried:

I have tried Windows default text box with Auto Complete. But, Length is restricting to text box length.

Hi There,
I'm not sure I fully understand your question but I think I have done something similar. Maybe you can adapt it to your needs.

I based my solution on this example
Search As You Type in C#

When I type in the search text box a data grid below lists all the matching items the more you type the fewer matches there are in the data grid. I used this to sort through 10,000+ contact names and addresses to find and select the one I want. Kind of like how Google search works. The code is surprisingly simple and very quick.

Good Luck and I hope this idea helps you.
