How can I change display height dynamically?

Hi,
I have defined layout style as "table-form". I want to control display height of a field depending on thich form user is in. In table, display height is "1" , but when user clicks edit and goes to form style, I need to change display height to "5".
I belive it can be done using EL expression.
Can anybody enlight me?
Thanks

It is easiest to make two separate items based on the same attribute. One item only displayed in table with height 1, the other item only displayed in form layout with height 5.

  • How can I change text height without converting to outlines?

    I work in a sign company and often need to set up text at specific sizes. When text is CAPS it isn't so bad, but when in Title Case it can be a pain....
    For example, if I need 2" high letters, generally it would be relative to the capitalized version of the first letter of the word (regardless of ascenders and descenders).
    Some times I need to do several at a time, so changing them individually is very time consuming when I have to convert each word to outlines and then adjust each word for compensating for ascending and descending letters.
    I'm wondering if there is a quicker way to accomplish this without converting the curves?  Also, I notice that when I change the font size (in Character palette) to 2", for example, when outlining the text is actually smaller.

    signguy(there),
    You may:
    1) Tick Edit>Preferences>General>Use Preview Bounds;
    2) Select the Type and Effect>Path>Outline Object.
    That will reduce the Bounding Box to the actual bounds of the letters, and keep the Type editable.
    Remember to untick Edit>Preferences>General>Use Preview Bounds before you get a reverse issue.

    Hi,
    If you want to add fields to a list, as you have written your form in JavaScript, you can take consideration of using JavaScript Client Object Model to add/delete fields dynamically.

    If you want to achieve it with Form7, it is recommended to post the question to its forum to get quick and confirmed answer.

  • How can I change the display of Inbox in my iPad's mail app- so that it takes up the full screen?

    How can I change the display of Inbox in my iPad's mail app- so that it takes up the whole screen, as opposed to just about one third; the other two thirds display the full text of the selected email?

    You can't change the display in the Mail app, if you are holding the iPad in landscape orientation then the left-hand third will be for navigation, and the right-hand two-thirds will be an email. If you hold the iPad in portrait orientation then the navigation section becomes a drop-down section.

  • How can i  change the column label text in a alv table display

    how can i change the column label text in a alv table display??
    A similar kinda of question was posted previuosly where the requirement was the label text was needed and following below code was given as solution :
    <i>*  declare column, settings, header object
    DATA: lr_column TYPE REF TO cl_salv_wd_column.
    DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
    DATA: lr_column_header type ref to CL_SALV_WD_COLUMN_HEADER.
    get column by specifying column name.
    lr_column = lr_column_settings->get_column( 'COLUMN_NAME1' ).
    set Header Text as null
    lr_column_header = lr_column->get_header( ).
    lr_column_header->set_text( ' ' ).</i>
    My specific requirement is i have an input field on the screen and i want reflect that value as the column label for one of the column in the alv table. I have used he above code with slight modification in the MODIFYVIEW method of the view since it is a process after input. The component gets activated without any errors but while run time i get an error stating
    <i>"The following error text was processed in the system CDV : Access via 'NULL' object reference not possible."</i>
    i have checked in debugging and the error occured at the statement :
    <i>lr_column = lr_column_settings->get_column( 'CURRENT_YEAR' ).</i>Please can you provide me an alternative for my requirement or correct me if i have done it wrong.
    Thanks,
    Suri

    I found it myself how to do it. The error says that it is not able to find the reference object i.e  it is asking us to refer to the table. The following piece of code will solve this problem. Have to implement this in WDDOMODIFYVIEW method of the view. This thing works comrades enjoy...
      DATA : lr_cmp_usage TYPE REF TO if_wd_component_usage,

    Get the entered value from the input field of the screen
    node_year  = wd_context->get_child_node( name = 'IMPORTING_NODE' ).
    elem_year  = node_year->get_element( ).
      elem_year->get_attribute(
       EXPORTING
        name = 'IMPORT_NODE-PARAMETER'
       IMPORTING
        value = L_IMPORT_PARAM ).
      WRITE L_IMPORT_PARAM TO lf_string.

      IF lr_cmp_usage->has_active_component( ) IS INITIAL.
        lr_cmp_usage->create_component( ).
      ENDIF.
      lr_if_controller  = wd_this->wd_cpifc_alv( ).
      lr_column_settings = lr_if_controller->get_model( ).
    get column by specifying column name.

    For sideloaded content the nook pulls the metadata from ePub file itself.  I would suggest looking at a program like Sigil or Calibre that will let you edit the metadata in the book to make it appear like you want.
    For the PDF vs ePub - No, that's the way PDFs work (think of them as graphics, not text), wheres ePubs are Web Pages - so  no you can't them to behave exactly alike without converting the files.

  • How can I change the aspect ratio of an image display

    I am snapping a sequence of images and using imgPlot to diplay the images. However, due to my camera specifications [it's a Pulnix 9701 with Pixel Size 11.6μm (H) X 13.3μm (V)], the image I get displayed is elongated in the horizontal direction, i.e. if I snap an image of a square, I get a rectangle on my computer display.
    How can I change the aspect ratio of the display on my computer? The only parameters I have seen so far just control what portion of the image is acquired or diplayed, but none actually changes the aspect ratio.
    Thanks in advance for any help.

    If you are using an analog camera, you can set the aspect ratio in MAX. This will correct for non-square pixels.
    If you are using a digital camera, I don't think there is a way to fix it during acquisition. You could resample the image to correct the ratios, but that would be a slow, time consuming process.
    One other possibility is that your computer monitor is in a mode which is not a standard 4x3 configuration. For example 640x480 and 800x600 are 4:3 ratios. 1200x1024 is not, which tends to distort your displayed images.

  • How can we change the  color of the image for product display for different

    Hi All,
    How can we change the  color of the image for product display for different colors, to be displayed on site.
    jeff

    Hi priya,
    The requirement that you have stated is not a standard feature in ISA CRM. In order to do the same, you will need to modify the standard ISA code in Java. A common path for the solution would be as follows:
    1. Colours
        a. Maintain a text type for Color under the object - PCAT_ITM in Customizing.
        b. Modify the standard search of ISA to search within your new text type as well. (In standard it only searches in Description.
       c. Maintain all shirts colour data in the new type created in step a.
       d. Your requirement will be done!
    2. Price
      a. Use list prices for your shop and assign the appropriate condition type, acces in your catalog.
      b. Modify the standard search of ISA to search on the list prices as well.
      c. This too will be done!
    3. Accessories - This is very tricky, and will require some exploration. However, here's my opinion,
    a. Search for the standard function module, which will return the accessories when provided the product as an input.
    b. Modify this function module according to your requirement and ensure that it can be accessed remotely.
    c. Modify the JSP as in steps 1b and 2b above to call this new remote-enabled function module.
    d. Now you're done!!
    The ISA modification part is not so simple, you need a really good guy like "Sateesh Chandra" who'll be able to handle your requirements. This is all I could manage, hope it is some help to you!
    Thanks & Regards,
    Nelson.

  • All photos in portrait format are displayed blurred in the preview mode "fill" of the library. In all other modes e.g. "fit"or "1:2" the photos are sharp. How can I change this, so that the photos are still sharp when displaying them in the mode "fill"?

    All photos in portrait format are displayed blurred in the preview mode "fill" of the library. In all other modes e.g. "fit"or "1:2" the photos are sharp. How can I change this, so that the photos are still sharp when displaying them in the mode "fill"? My Lightroom release is 5.7.1.
    Thanking you in anticipation!

    I'd like to get all these '-1 suffix' files together with their associated Develop adjustments into one folder (if they aren't already) so I can see them in Grid view in the Library module, which I use as my basic starting point for everything else at this early stage of my Lightroom 'career'.
    To see what folder these are stored in, right-click on a photo and select "Go to Folder in Library".
    Advice: if you are going to use Lightroom effectively, you probably want to stop using folders as your method to create a grouping of photos that are already in Lightroom; there are plenty of built-in tools, such as keywords, collections, color labels, etc.
    I don't understand why the search on the entire catalog picked up apparently the same two file versions but also got the Develop adjustments when going to the relevant Folder didn't show the adjustment black squares against each image in Grid view nor were they there when the images were opened in the Develop module.  Perhaps if I understood this, I'd be a bit more confident of moving forward myself.
    These are most likely different versions of the same photo, in different folders. Lightroom stores the edits in its own catalog, and so it knows that one folder's photos have edits, and the other folder's photos do not have edits. Please understand that Lightroom is a database, it knows where the photos are at the time you import them (or add them to the catalog by synchronize), and then if you move things around in your operating system, Lightroom does not know anything about that and problems begin. Thus the advice to organize using Lightroom tools and methods and not operating system tools and methods.
