How to dynamically change the combobox values based on another combobox value? - extjs

I have multiple combo boxes which should be inter related. I need to change the combo box values based on a value selected in one combo box.
Say, If I select one Category in combo box, then all the other combo boxes should be getting values which are related to Category.
Please have a look at the table below:

If you have a lot of values ​​in your combo-box, it's not necessary to early load all.
You can fill them "manually" by a "querymode : local".
So, your query who fill your combo should depends on the others

Each combobox needs to be assigned a store .
In your case, you can create one store with only Categories data and another store with all the data shown in your grid one for each of the dependent combo boxes.
Using onselect event listener of Categories dropdown, you can filter the stores of the dependent comboboxes.
(If you want to know how to define a combobox and store, you can look at the below example

and several others from sencha docs.)

ExtJS: How to group items in combo box, but then show all detail records in display text

Using ExtJS 6.x. I have the following Fiddle:
bind grouped combo box value to detail displayfield
To start with: I would like to show just a single instance of each item in the combo box instead of the multiple instances that show up for each item (thus, instead of "one" and "two" showing up multiple times, I only want these to appear once in the combo box). Is there a way to do the grouping within the viewModel to achieve this?
Assuming then that the combobox items are now grouped accordingly, I then want to show the details in the displayText area, so that for example, if I choose "one" from the combo box, the detail area would show ALL the ids associated with this, those being '1' and '2'.
I solved this, although it feels a bit kludgey:
First, I created an SQL view with the records grouped together (using a unique key of "name + code")... then, I created another SQL view where "name + code" was another field for the original table.
I then used associations in my models to link these two entities together, and thus, used data bindings to link the record selected in the combobox to a grid.

Codename One ComboBox how to highlighting already selected value

We are able to create ComboBox and populating data too. But we need to highlighting already saved values. Can you please suggest code for this.
Our requirement is if Combobox has 1,2,3. If I select 2 and save. We need to set the combo box value 2 in such way that when we open the Combobox need to display this 2 as highlight value along with 1,2,3 values.
Simply same as select box option selection.
I would generally recommend avoiding ComboBox altogether.
Assuming this isn't an option you will need to define a renderer and disable the OS specific 2 render mode using a theme constant:
otherPopupRendererBool=false

Limit data based on UniqueCount

I have charts on a tab, that should only show if 1 value from a column filter is selected.
For example if a field named: BUSINESS_UNIT has values of "HR","FIN","IT" The charts should only show data if 1 value is filtered on. Such as "HR."
These charts do not contain the BUSINESS_UNIT field itself.
I tried using the Limit Data Using expression, but for some reason the limit expression UniqueCount(BUSINESS_UNIT)=1 doesn't work.
How would I hide the data in the charts, unless 1 BUSINESS_UNIT is selected?
What you could do is hide the filters panel and create radio buttons on a new text area for each property to mark data. If you need help setting this up let me know. Then in your visualisations limit data using markings and show an empty visualisation if no items are marked.
One downside to this is maintenance, if the values change you will have to update the UI.
Another possible solution (untested) is to change the filter panel properties from checkboxes to radio buttons.

Populating multi select control from multiple values when form opens in AX

I need to populate multi select dropdown from multiple values from table like this
value1;value2;value corresponding to each record (which is in list box).
When I select any record in list, the value of multiselect combo box changes corresponding to the record in the list box.
I am able to select multiple values for each record manually when I click any record in the list. However, I want the text box of dropdown to be populated automatically whenever I click any record in the list box
There is no multiselect combo box control in AX. It can be simulated with a technice based on Grid component and edit methods (special method type in X++), but you should clarify your question indeed.

Get data into one form field based on another's field in access 2003

I am trying to update existing form field based on another combo box selection.
I have a DB with such relations: http://img696.imageshack.us/img696/7396/relationse.jpg
I have a such form: http://img233.imageshack.us/img233/9758/getdata.jpg
Which Offers to select only existing IDs in database.
All i want to do is when user selects (change) existing combo box "Filmas_ID" value, in nearby input box with value "Unbound" shows up data related to this ID (You know - Just for informative reasons).
(SELECT Filmas.Nosaukums FROM Filmas WHERE Filmas_ID = combo box "Filmas_ID" value; )
It looks very simple, but i had no success yet to get it work.
Thanks for your help! =)
There are a few handy ways to do this, one involves including the data in the combo. Let us say the combo is set up like so:
RowSource : SELECT Filmas_ID, Nosaukums FROM Filmas
ColumnCount : 2
You now have a choice of setting the column widths so that filmas_id is selected, but Nosaukums is shown in the combo. Alternatively, you can set the textbox to reference the combo column, like so:
= mycombo.column(1)
Where columns count from zero.
Another method is to use DlookUp in the control source of the textbox:
= DLookUp("Nosaukums","Filmas", "Filmas_ID = " & mycombo)
Where Filmas_ID is numeric and the required value is in the bound column of the combo.
