Is there a way, in Axapta/Dynamics Ax, to create an Extended Data Type of type integer which only allows enering values in a specified range (i.e., if the extended data type is meant for storing years, I should be able to set a range like 1900-2100), or do I have to manage the range using X++ code?
And if I need to use X++ code to manage the range, which is the best way to do it?
I suggest you use the ''validateField'' of the corresponding table.
Search for the method in AOT\Data Dictionay\Tables to see many examples.
You can can't specify the range on the extended data type itself. If the type is used for a table field, you can add code to the insert and update methods of the table, in order to validate the value whenever the record is updated. This approach could however have a cost in terms of performance.
You can also choose to just add code the the validateWrite method of the table, if you are satisfied with the validation only taking place when the value is modified from the UI.

I need to make a search form where I need a range slider so a user could choose price_from and price_to. Something like this
What is the best way to implement it?
The only I have found is range type field
It is pretty close to what I need, but it has only one value while I need two values (price_from and price_to)
You are are correct to assume that you need two values (min and max). When I encountered a similar problem, I created two hidden fields for the same purpose.
To fill those hidden fields with values, I used a JS library that rendered the widget and stored the user's input in the hidden form fields:

I’m trying to create a dashboard filter in Tableau. All but one of my graphs have the same primary data source A. The filter will affect all these graphs as intended. However I have one sheet where the primary data source is B, and the secondary data source is A. I can’t get this particular graph to link to the quick filter I’ve created. Does anyone know of a workaround for this?
The easiest way to filter multiple data sources from a single user control is to use a parameter along with calculated fields in each data source that reference the parameter setting. The calculated fields can then be put on the filter shelf for the appropriate worksheets.
This solution doesn't fit every circumstance.
Parameters can only have a single value, and the list of arbitrary values must either be defined statically in the workbook or allow the user to enter an arbitrary value. You can't dynamically lookup the list of legal parameter values in a database table (although you can use a field to populate the list initially).
Parameters are independent of any data source.
So if these restrictions don't hamper your use case, then you can have one parameter control on a dashboard that influences the filters applied to many worksheets. The simplest calculated field used for filtering could just say [My_Field] = [My_Parameter]. You can allow extend this idea to define parameter values that reference multiple choices like: "A", "B", "A and B" and then adjust your calculated fields accordingly. At some point, this approach gets unwieldy.
Another approach is use a worksheet as a filter, by displaying marks for each option, and then using filter actions to use the selected marks to filter other worksheets. This approach allows multiple selection, and dynamically loading choices from a database table.
I'm trying to extend a query in Dynamics AX that populates the "My Projects" window. I've found the query that I need to modify, and tried to modify it, unfortunately, the character limit in the Value field (see screen shot), is not sufficient to allow me to enter all of the text I need to extend this query.
I've explored adding additional ranges, but I need to add additional OR arguments here and it appears that adding additional ranges will AND the range instead of ORing it.
Is there any way to bypass this character limit?
If you add several ranges to the same datasource field, the ranges are combined with OR in the SQL.
This is useful sometimes. See this queustion for a (klunky) example.
I have some initial conditions that are specified by functions of (x,y,z).
I would like to programmatically define a field whose values are a function of (x,y,z). Can this be done as part of field construction, rather than looping over cells/faces and setting each value individually?
Further, can I set the internal field and boundary values in a straightforward manner?
You might want to use #codeStream directive to enter the generating code directly in the field defining dictionary, see official documentation.
Also you might want to look at extensions such as groovyBC, funkySetFields or swak4Foam.
Hello friends i am to add optional parameter to pass these in a method the parameter may vary every time.
And i need to pass these parameter to a method, so my question is how should i add these optional parameter to a collection and what kind of collection object should i use and how should i use that.
i elaborate here, i am having following fields.
1)course field(a drop down list) and on selected index change of course a check box list of corresponding branches are visible now i can select branches of choice by putting check mark on check boxes.(both course and branch are compulsory fields)
2)pass_out year which is a compulsory field.(a text field)
3)education gap which is optional so the text box may be empty as well and may having a digit as well.
4)required first year percent, second year, third year, final year, current degree, high school, senior secondary, gradation, post graduation, diploma percent, birth date which are all optional so these fields may also be empty or having a digit in the text box.
5) current backlog(a drop down list)having choices all, yes , no.
6)number of ATKT text box which may also be empty or can have a digit.
So i want to store all these variables value to some collection of object which will passed to a different method by passing all these variable from here,
But i am unable to figure out how should i store these optional variable to some object and how should i pass them to other method where all variable values will be taken out and an appropriate query will be written to interact with the data base to get the data table.
please elucidate me on this please. I am really not getting a feasible solution, i have thought of few options which i can let you know if you demand but those all seems to be tedious and difficult and redundant so i see help from you.
Don't bother with optional parameters or some collection of parameters, just decide how you will represent each value best, including how to represent empty values.
For a string value you can just use a null reference or an empty string. For a numeric value you can use a nullable int (int?). For a list of checkboxes where none is selected you can send an empty list.
When figuring out how to use this in a query to the database, it's easier if you have the values as parameters that always exist even if the values represent an empty value, rather than to have to parse out parameters from a collection where a parameter might be missing. Also, as you have different data types it's better if you can use an appropriate data type for each parameter, instead of casting everything into the same mold just to fit in a collection.
