Consider the heading (ABAP) pseudo code on a SALV-Grid.
I need something like this, or, some way to remove the visual vertical bloating of rows in the grid when the columns that differentiate them are hidden.
After a lot of reasearch, I doubt that such a thing exists, so I need to work around it.
I want to change just the view, I don't want to modify the underlying internal table.
Any ideas on how to best accomplish this? Events maybe?
Make a copy of the data from your table and remove duplicates from the copy. Pass the copy to your grid. The hurdle here would be ensuring you update the original table if edit, delete, and create functionality is enabled in your grid.

I have a database where I don't want some fields showing depending on data in other fields. I'm still new to VBA, having learnt how to do things I need via the internet (there's not much call for it in my job so like to try it out on side projects) for the things I need and have managed to create some code that hides certain fields that aren't needed, depending on what's been entered in another field and that works okay, if not perfectly (I'd like it to only work on the current record and not all of them at once but will worry about that later). My problem is, if I'm entering information onto a record and any of those fields become invisible exactly as I would want them to, then if I have more records to complete and load a new record, those hidden fields are also hidden on the blank record before any data has been entered and I want each new record to show all fields from the outset.
Another thing I've noticed is that if I close the database, next time I go into it the hidden fields have unhidden themselves again so I know I'm missing something important.
Here's a screenshot of a bit of the code where I want 2 other fields (What_reason and Date_sent_to_new_owning_School) to be visible depending on whether the answer in the current field after update is "Standard" or "Non-standard":
I'm sorry if this is really entry-level stuff but I AM entry level and trying to learn. This bit does work, albeit not perfectly as I'd like it to only work on the record I'm in at the time, and not go through and hide that field in all the other records at once (which it's doing).
I've searched everywhere but can't find the answer and although I've tried, I'm nowhere near good enough at VBA to try and use common sense to work it out. Is this something that can be done? I'm okay with computers generally and with Access too but I'm aware there's an awful lot I don't know and this is why I'm trying to do new things and learn stuff that I've not used before. I have tried all day to get this to work but am admitting defeat and am hoping somebody here will be able to help me. I'll probably need 'idiot level' advice if that's possible, I know my limitations. :)
Do you know how to use the Event tab in the Property Sheet? You can set all of your fields to [field].Visible = True on either: On Current, On Load, or On Open
Screenshot of the Property Sheet and for the field that determines the visibility of all of the other fields; you can use the Event: After Update so that way when you click/tab away from that field, it'll make those changes for you!
Property setting affects ALL instances of control. Control will be visible/not visible for all records depending on conditions of current record. Therefore, dynamically hiding controls on form set in Continuous or Datasheet will NOT give the desired result of
only work on the current record and not all of them at once
Db is not going to 'remember' dynamic setting - code needs to be executed when form opens and/or navigating records - so it is needed in OnCurrent event as well as control's AfterUpdate.
Conditional Formatting can dynamically enable/disable textbox/combobox by record although control is still visible.
I want to create dynamic table with vue.
I have button and table with 3 columns.
I want that if i click on the button only the first and second colume will show and on addition click only the first and the third.
So my question is what better is to do:
A. to hide one colume on click
B.to create customized table in the vue.js code by click
without knowing any specifics, I'd go with easiest way, which for me would be to do two things. Use button to toggle value ie. #click="showCol=!showCol" and the for the columns I'd do <td v-if="showCol">{{col2data}}</td><td v-else>{{col3data}}</td> you can also do <td>{{showCol?col2data:col3data}}</td> And I'm sure there are some other ways too, but I'd try one of those. The former should use a shadow dom to replace the data, whereas the second option would not, so I'd imagine that if you have enough rows where that would matter, the second version may be faster. As always, test & measure if you want to know what's better.
I have been googling for a good description of this but am not having much luck. I am pretty new to SSRS reports and I am probably not using the correct terminology here. If someone could point me towards an article that describes this that would suffice.
Basically I want to pull a bit into my report, and based on the value of that bit (or maybe a varchar) I want to render an address in different formats, or add/remove some sections completely form the report. I suspect this is basic functionality but am having trouble finding an example. Any help would be appreciated!
Thanks!
If you have a table/matrix the best place to put stuff like this is in columns that are outside of the detail or any groups at the top of the table. You can merge all the cells and add rectangles to add specific formatting. The neat part about using header columns is they can be hidden and the space used will not be rendered.
Say you have a table and Row1 and Row2 contain different formatting of the same data. If you have a report parameter named ShowFormat1 then you can optionally hide/show the correct row with formatting.
Click Row one and Set its Hidden property to =!Parameters!ShowFormat1.Value
Click Row two and Set its Hidden property to =Parameters!ShowFormat1.Value
The same concept can be applied to all elements if you are not using a table or matrix. Non-repeating controls, Rectangle or Image for example, can be hidden but the space used will still be rendered.
I'm trying to create a filter so the user can choose any of 40+ fields to display in a query result that has been dynamically created via VBA.
This is something I see standard in a lot of programs so I figure someone must have code that does it without me reinventing the wheel. Unfortunately I haven't been able to find it online.
Basically when it starts all the field names are listed in the left box and the right box is empty. The user can click a right arrow button to move the fields into the right box or a left arrow to remove them and put them back in the left box. Also the user can use up and down arrow buttons to change the order of a selected field in the right listbox.
Once I have the right listbox populated and ordered correctly I know how to execute the query properly.
If you are unable to find a full example for this then you'll need to work through it step-by-step yourself. Here is an MSDN link for the ListBox control. There are links to the various methods and properties of this control at the bottom of the page.
Essentially, clicking a button (your arrow(s)) triggers the Click event;
In this event you might need to loop through to find the Selected item;
If the listbox is multi-select then you can examine the ItemsSelected collection;
Then you would use the AddItem and RemoveItem methods to move them for right-to-left or left-to-right.
I cannot recall currently whether the Field List option is bound to the table, or whether it just populates the list once when the form is loaded. If it is bound then you would instead need to use the Value List option and use VBA to retrieve all the field-names, and use these to set the RowSource (you may be doing this already).
In either event (Field or Value List) I don't believe the lists can remain sorted automatically (unlike in VB.NET). You will probably need to split the RowSource up into a (dynamic) array, find a simple sort routine to sort the array, and reassign the sorted items as the RowSource.
An alternative would be to create two temporary tables and use ADO (or DAO) to insert and delete rows between them, then use SELECT statements each time to re-populate the lists. This has the advantage that the SELECT can include an ORDER BY clause to sort the lists each time. However, It perhaps involves a little bit more effort (to maintain, and delete, the temporary tables).
You might, however, want to continue your search as I suspect an example is out there somewhere. Good luck.
I have a table that has a series of filters across the top of it (as per usual.) This table feeds a massive graph that has multiple series of data in it. In order to hide different series of data I have grouped the information in the tables. I can then click on the minus button to remove a series of data from the graph by collapsing the group, or click the plus button to add it back in the same way. Yes, I know, not the best solution. It was an early effort, what can I say? My default is for all data to be hidden (all groups collapsed).
I have a user (a very important user) who wants to be able to use the filters across the top to find the specific series they are looking for. The filter will find the collapsed series just fine, but the series will not display because it is collapsed.
So, What I'm trying to do is get all groups to auto-expand when the filter is activated. This should work as a stop gap measure until I can simply redesign the chart.
The Problem: I can't figure out how to make Excel notice when the filter has been clicked on (or otherwise used). I've tried using Worksheet_Change and Worksheet_SelectionChange, but neither of them activate the code I have set up in the listener. That code, FYI, checks to make sure the filter is in use and adjusts the groupings accordingly. It should work fine if I can just get Excel to notice it's existence.
I've looked into making my own listener, but there's nowhere in the code I can insert it to make it activate. I just need a listener that will notice when the filter has been changed.
Any thoughts? After an hour of searching I'm stumped...
Okay, after some research I figured out a work around. The big problem here is that changing a filter does not raise any events that can be heard by VBA. Big problem.
Simple Solution: Create something that will activate a listener.
What I ended up doing was finding a cell somewhere outside of my table that wasn't going to be affected by the collapses, then I added a very simple formula (=Count(H:H)). Now whenever the table is collapsed the count is affected which activates the Worksheet_Calculate listener. And voila! I can dynamically change the groupings all I want :-).
So there you have it. If you need to detect a filter being activated via a Worksheet listener, you just need to set up a formula to activate the calculate listener.
Reference: [MSDN Article on the same thing].1 There is apparently a much more robust way to fix this problem as well which is detailed in the article.
You mentioned table, so assuming it's PivotTable you may try,
Worksheet_PivotTableUpdate(ByVal Target As PivotTable)
If it's simply a Targe Range change then,
If Intersect(Target, Range("A2"))
