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.

Thank you!

Directory Listing in Gridview

Asked by Real_coffee in Programming for ASP.NET, Visual Basic Programming

Tags: Visual Studio, asp.net, gridview, getdirectories, listing, navigation

hi experts,

Visual Studio 2008 / VB Code / asp.net 3.5

I am trying to find a way to list directory contents (including folders) into a gridview and allow basic directory navigation; If users click on a subdirectory or parent folder then the gridview lists the new directory contents.

Also I need a checkbox/button in the gridview that the users can press that will allow them to set a directory as 'home'. So if they press the button it populates a label or textbox
on the form with the full directory Path (That way I can save it and the next time the record is loaded I can then list all the files within the 'home directory').

So far I have a gridview that lists files with hyperlinks and thats about it (attached).

Although I do know how to get the folders with DirInfo.GetDirectories() I cant even figure out how to make them appear alongside the files in the gridview :(

I've searched experts and other forums but cant find a VB solution to this.
