Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Cascading search in a grid?

    I have a use case where I would like to have a cascading search in a grid search part. The situation is I'm working on an invoicing system for a client that rents their product to a few hundred companies and some of those companies are "parents" to "partners" who also own "sub companies" who own multiple "stores". Think auto rentals or rug shampooers in grocery stores. So the structure is below. For some companies the invoice goes to the parent, sometimes to the partner, sometimes to the sub.

    parent A
    ___partner B
    ______sub C
    __________store D
    __________store E
    ______sub F
    __________store G
    __________store H
    ___partner I
    ______sub J
    __________store K
    __________store L
    parent M

    and so on. There are currently about 15,000 stores each with 1 or 2 products and they are constantly adding and closing stores and also renting and returning products and transferring rental products from one store to another. Most rental agreements are billed monthly and every sub has its own invoicing day. Very messy. I cannot change the structure of the business.

    So, for creating invoices, I have a grid with a search part where I can search by parent and optionally partner, sub and store. The invoices are then created based on the results of the search. That lets me create from 1 to a few hundred invoices at a time, and the client is happy with that. It works, but I'd like to have the seach cascade so the store list isn't 15,000 items long. So, for example if I select parent A, then the partner dropdown only shows B and I. If I pick B then the sub dorpdown only shows C and F.

    Does anyone know how to make the search cascade based on the selection in a previous search?

    Thanks, Pat

    Sounds like you need a Tree Control.
    See our Hybrid Option here;

    Apologies to anyone I haven't managed to upset yet.
    You are held in a queue and I will get to you soon.


      This is easy to do in a list, but I am not sure how to use grids. If you want to switch to a list I can help you out.


        Ted, thanks for the idea, but i can't see how the tree control would help me with the search filter.
        Thanks Russell. I have seveal other non-standard items working and this cascading filter is the last piece, so I'd prefer to stick with a grid if I can. If I do move to a list, I'd appreciate some help, I'll let you know.
