The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

How to filter 2nd combo box based on the value of 1st combo box in a DataGridView in VB.net 2005?

Zones: Microsoft Visual Basic.Net, ADO.Net Class Library, Visual Studio .NET 2005

Tags: DataGridView Default Error Dialog:

* I am trying to display Order Details of a related orders of a customer in a 2nd DataGridView in my form from a disconnected dataset. This grid is to be used for updating existing orders and adding new orders. Displaying and updating is working fine.. no problem.
* In my DGV along with other cols, I am displaying 3 cols as 3 dependent combo box for Main Item, Sub Item and Detail Items. Sub Item combox will ONLY display the related sub items of the Main Item selected in the previous Main item Combo Box. Similar for Detail Items. I am using 3 separate unfiltered dataset for my 3 codetables. I want to filter my next combo box only when previous combo box is clicked or changed.
* This feature I have easily in my VB6 application long before. I have tried to filter the datasource whenever the MainItem combox is clicked or value change using DGV_CellBeginEdit and DGV_CellEndEdit procedures. Also tried DGV_CellLeave procedures. When I move/click 1st combo box it works fine showing all the expected value, but whenever I move to next combo box which is to be filtered I got this annoying error message. Through debugging it seems that filtering is working BUT could not display the expected result in the 2nd combo box.

* PLEASE HELP ME RESOLVEING THIS PROBLEM. I CAN'T MOVE FORWARD UNLESS IT IS SOLVED.
