Within AX 2009, I have, through compare and compile, added two new controls within a datagrid on a form, a Real edit and a combobox. I have compiled with no issues. The Allow Edit property is set to Yes on both controls.
However, on the form, if I edit one row, whether typing a new number with Real edit or combobox, and don't hit Save but hit the Down Arrow key, the data I typed on the previous records is duplicate in the next record and so on until I release the Down Arrow key, rather than just setting the focus on a new record.
The table where these fields were created doesn't exhibit this behavior. The focus simply moves to the next record and what was typed will not carry over to the next record. Only the form does this...
Has anyone seen this behavior before with AX forms?
You may have omitted to specify the data source on the grid itself?
Or if the new controls are based on Edit methods on the data source, have you got the data source parameter in the method signature?

In App Maker, what is the simplest way to achieve the same result with a dropdown box that you can with a suggest box, which can return the whole record when you make a selection giving you the ability to assign associated record values to other fields on the page?
Consider a data model with three fields, (Code, Description, and Severity). Add a dropdown box to select the Code. Have the selection, (probably using onValueChange or onValueEdit), write the selected Code's Description to a label field beside the dropdown box. The Code's Severity will also be used to affect the style in some way like background color or something, but for this answer, merely assigning the value to a scripting variable will be good enough. It's the record value access and assignment mechanism I am after.
Clarification: This data model will not be the page's datasource. It is a secondary reference table used for assigning a code to a ticket. You can also assume that a record value will be written to a field in the page's datasource as well.
I would appreciate the simplest low code solution as we will have non-programmers attempting this. Thanks.
As long as you leave your value binding on the dropdown blank the following should work:
Set the options binding to:
#datasources.YourDatasource.items
You may want to consider changing the 'Names' binding to be the projection of a particular field in this datasource otherwise the values showing in your dropdown will only be the 'keys' from this datasource.
Then in your onValueEdit event you will gain access to individual fields like this:
var item = widget.datasource.item;
item.YourFieldToEdit1 = newValue.YourOtherDatasourceField1;
item.YourFieldToEdit2 = newValue.YourOtherDatasourceField2;
That would probably be the simplest way.
I have a SQL db that holds the records for my page. On my page I have a details view I want to populate with records from my db. I can populate the records just fine, I need to be able to populate in records based on a user selection from a drop box?
To clarify, on my main page I have a drop down list with years (ie. 2011, 2010, 2009), and a drop down containing account codes (ie. six-digit numbers). Based on what the user chooses for the year (for example 2010) and the what they choose for the account code (for example 123456) I want to populate the details view (which is on a seperate page) with only those records from 2010 and with the account code 123456??
Far far haven't seen a way to make it work?
To fill the DetailsView based on input from form controls is actually quite straightforward. You're basically using the controls to supply parameter values to plug into the WHERE clause of a select statement.
In essence, you define your SqlDataSource to take Control parameters.
There's also documentation here: http://msdn.microsoft.com/en-us/library/z72eefad.aspx
And an article with screenshots here: http://www.asp.net/web-forms/tutorials/data-access/accessing-the-database-directly-from-an-aspnet-page/using-parameterized-queries-with-the-sqldatasource-vb
If the details view is on a different page, you can do the same thing using QueryString parameters, but that leaves you open to tampering. (People changing the values in thequery string to get at records they shouldn't see.) If tampering isn't an issue with your specific situation - the data isn't sensitive in nature, then it shouldn't be an issue, but its' something to be aware of.
[Thanks to Filburt and Devjosh. I have restructured the post and included my attempt approach. ]
I have a table on my SQL DB call ReportList which is a list of report. I need to go through that list and interrogate the reportserver, eport by report, to populate a table called ReportParameters. The ReportParameters table has a column for ReportOwnerID which needs to contains the ReportID value of the corresponding (owner) report as listed in the ReportList table.
This is in VB.NET 2005 ASP2.0 and I have ended up with a mess. Please help me with the cleanest approach to doing this.
It needs to work so:- I have a listbox of the reports as per REportList and a GridView that list all the parameters (uniquely - most of the parameters are common to many reports) the idea being that the parameters get set once and the report can be kicked off by selecting them in the ReportList CheckListBox and clicking on Execute.
I would like it that as I click on a particular report in the ListView, the relevant parameters in the Gridview get a green background and those that do not apply are red. The leftmost column in the gridview contains tha Parameter NAME (not editable) and the next column must be editable to populate the value.
DONE SO FAR:
I have tried on clicking the EXECUTE button , to build a parameters string in a testbox and call that with the Javascript OpenReportWin() function when I open the report in a new window. This works fine, but my biggest issue it interrogating the reportserver reports to get back a list of parameters and dooping them into a table. I have triend to use a hidden DataGrid bound to a ds onto the reportParamaters table; I have tried to poulate it using a datalist but I cannot get the hang of these thionsg and its looking messy. Ther must be a simple clean way of gettting the .GetParameters resultset back from the report server and populating the table without having to create a reportviewer object and cycling through the list of reports - it then has to render each report before you can get that list out.
Thanks
I will withdraw this for now. I will submit a solution when I am comfortable that I have reahced a clean solution.

PLEASE CLOSE!!!
Here is my scenario.
I have an objectdatasource-bound gridview where i want to show Students {name, age, class}
name:string, age:int, Class:Foreign key, int
I also want to edit it, but when doing so i want to show a dropdownlist for the class field.
Currently i solve this by
a)creating a view, binding the grid to that view
b) on the editItemTemplate, put a DDL and bind it to the Class table.
What i want to know is if there is a way without involving the view shortcut.
NOTE: this question, Bind column to a different entity source than the gridview is
is somewhat related, but not quite the same thing. in that example, the OP just wanted to show the related data. Since am also updating, i need both the key and the value.
I have a selection list that is generated dynamically, it lists a number of checkboxes that are based on an end-user editable table, as such I have no idea what data, or how much, might be contained in this table and how many checkboxes or what they might contain, other than the primary keys of the table.
The user will select the checks they wish to see, and then control is passed to another page via PostBackUrl. The second page has to figure out which records to show (build it's where clause) based on the checkboxes checked in the previous page.
So, my problem is several-fold. First, asp:CheckBoxes don't have values. This can be worked around by a number of methods. Right now, i'm using a placeholder and dynamically creating the checkboxes in the ItemDataBound event of the DataList. I set the ID to "CheckboxKey1Key2" (where Key1 and Key2 are the primary keys of the check items).
Second, I have to walk through the controls of the PreviousPage to dig out all these values. That in itself is also a pain, but doable.
Now, my thinking is to build the where clause of my Linq2Sql query based on the keys I got from decoding the checked checkbox names. This all seems like a lot of jumping through hoops for something that shouldn't be this difficult. Am I missing something? Does anyone have any better solutions?
Make a class with a structure for your values that will be useful and easy for you to use on the result page. Then when the user clicks whatever it is they click to go to the result page, loop through the DataList, create a collection from the checked items, and you will only need to grab one object instead of everything, when you need to format your query.
Then when you get to the result page, loop through the collection and build the query in the loop. Pretty easy and not much code.
