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.

  • Populate drop down box with variable passed from Parent Grid

    Hi All

    I have a grid where I do a search on several elements, i.e. title, forename, surname etc on a customer table, if the customer does not exist I have an option to create a new customer and which time I pass the values from the search part...

    I can then populate the fields on my child grid with the exception of title which is a dropdown box ..., I have tried the populatedropdownbox grid method but this appears to have little effect.., is there a way I can set the field value from the parent grid ?

    many thanks in advance

    john

    Are you working with the Detail View of the grid as your child grid, or a separate child grid? How are you populating the child grid fields?

      Hi, the child grid is a seperate grid that loads when a button is pressed.At the same time I am using Java to get the values from my search field.

      On the child grid that is loaded, I have another button to populate the controls again using Java
      thanks

        Hey Miles,

        When you get the values from your search fields, using Javascript, what do you put them in... window variables?
        When the child grid is displayed, is it blank? And then you populate using a button? Just trying to get and idea of the flow.

        Nonetheless, it seems like you were on the right track with populateDropDownBox... why didn't that work for you.

        On my grid I have a Search part and I save a control value from Search into a window var...

        Code:
        window['custname'] = {grid.Object}.getValue('S','CUSTNAME')
        Then, in my Child grid (which is opened using a button and Action Javascript), in the Grid Event, onGridRenderComplete, I have...

        Code:
        var droplist = window['custname'];
        {grid.Object}.populateDropdownBox('D','CUSTDETAILCITY',1,[droplist],true);
        This grabs the value from the window var and replaces the current list in my dropdowncontrol.

        What was the problem when you tried to use populateDropdownBox?

          hi david

          The problem I seem to have was that the control wasnt being populated with data..., on my paretn grid I have the code
          title = {grid.object}._getValue('S','TITLE');
          then on my child grid on a button on the grid I have


          {grid.Object}.populateDropdownBox('G','TITLE',1,[title],true);

          But nothing appears to happen when I press my button

          thanks

          john

            Re: Populate drop down box with variable passed from Parent Grid

            You're crossing from one component to another so the variable doesn't get passed through. You need to use a global javascript variable using the 'window' namespace. Check out video M43 for more info, but generally what you need to do is... on your parent grid...

            window['title'] = {grid.object}.getValue('S','TITLE');

            and in your child grid...

            var title = window['title']
            {grid.Object}.populateDropdownBox('G','TITLE',1,[title],true);

            That should do it.

              Thanks for the update David, I will give that a try, I am also passing 4 other fields in the same way, which all populate OK using the same method, so not quite sure why this particular one isnt working for me .

              thanks again

                If you're passing the other fields in the same manner I'm not sure why they'd be working. I'm not sure how you're opening the child grid... that may have something to do with it... how and where's the child is opened.

                    In your child grid, have you tested to make sure the variable title is being set? Put an alert statement in just after you set the title. Otherwise, post your child grid so I can have a look.

                      thanks again for helping, the data is being passed correctly and displays with an alert

                        Hey John,

                        In the Grid you attached, I can't see a button with any code - no buttons at all. I thought there might be an Action button, but nothing there either. Attached is an image of the Grid in edit mode.
