So I'm using flutter in Android studio. I generated a list to show some values from am api that has data of things in a vending machine. 'Quantity' is how much of a item there is in the machine. When i set the state to increment a specific item in the list, the count for the single is increased or decreased for all the items not allowing me to update a single item. What i want to do is update the value for the quantity for a specific item only and save that data to the api. I did not set image like below
I believe you will have to set different values for those different items in a map file
like in your screenshot, you have doritoz, tortilas, etc etc
the action for clicking the button should be "doritozValue++" or "doritozValue--"
i don't think you can use a single value for the entire list
this is like working with a dropdown, if you want to set your list dinamicaly, you need not to have a quantity value var, you need to have a list of those vars, and you can access in your dinamically list by making a for, and accessing the determined quantity by: listQuantity[i], that is the determined quantity var for this determined object in the i position

How can I set a value to a Select2-Widget which is not in dropdown list? I load values from other table - but it is possible to deactivate entries there, they are not shown in list then. The problem is, that the value, which is not in list is not shown correctly, because the list does not know the item.
Is it possible to show (and on update save) the old value, but it should not be possible to select it from list again.
Is there a way to make a dropdown in SSRS limit what is shown as a value is typed. As it currently is it just goes to the first item starting with the letter, but in a big list, this still means a lot of scrolling to get to the desired value. This specific report is on SQL Server 2019, but if there is a way to do it for 2016 as well that would be nice to update some of the reports on older servers
Thanks
As far as I know there is no way to do this directly. However, you can do this with some compromise.
Let's say I have a long list of customers that I want to filter.
I create a dataset (dsCustomers) with a dataset query something like
SELECT * FROM customers
I have a parameter which uses this dataset as it's list of available values called pCustomer
If I want to be able to filter this list I would add a new parameter called, say, pCustSearch. This will be a simple parameter with no associated dataset. You can optionally allow NULL values.
Now I can change the dataset query for dsCustomers to be
SELECT *
FROM customers
WHERE (Customername like '%' + #pCustSearch + '%'
OR
#pCustSearch ISNULL)
NOTE: The pCustSearch parameter must be the first parameter (or at least before the pCustomer parameter)
Once you have filled in the search parameter and tab to the main customer drop down, it should filter the values that match what you have typed.
I am building a summary report which looks at users that are marked in a database as having a common trait i.e return all users by name in the last 5 years whose contract contains an end date.
This generates a figure e.g. [250]
I drill through on that figure to give a list report of names, first name and surname.
I have ordered the list A-Z
I would like to add a row of 26 letters at the top of the report and have each letter return only the names with the corresponding starting letter.
Would this need to be a further drill through or is it possible to refresh the existing list based on a user-driven selection?
Just add a custom parameter to your report. Right click on Parameters and Add Parameter.
(and so on...). Default value should be All then.
Then simply add the following filter to your tablix:
'Expression:
=Switch(Parameters!YourParameterName.Value = "All", True, Parameters!YourParameterName = Left(Fields!YourNameField.Value, 1), True)
If you are just using SSRS as it comes, then you can't refresh report content without running the report again, so you would either
re-organise your current report.
need another drill through report.
Depending on your layout you could group the data by the first letter and then have an collapsible row group to show/hide that group of names. To do this simply add a parent row group, set the value, group value and sort value all to =LEFT(Fields!myNameField.Value). Next set the visibility of the details row group to hidden and set the toggle visibility property to point to the cell that contains the letter from the parent group you just created.
If you have too much data to make this efficient the you might have to go down the additional subreport route.
To make life a bit easier, and to save you having to create 26 links and parameter values, I would do the following...
Create a table that stores the list of letters
Add a matrix to your report, that has a column group grouped on the letter value from this table. This will act as your 'filter bar'
Set action on the matrix cell to "go to report", point to the final drill thru report and pass the [myLetterColumn] value as the parameter.
There's no need to set available parameters assuming this sub-report will be hidden and only called from the parent report.
I have a report I need to develop where all Quotes should be listed where a specific Product is present. The product can be identified based on Product ID/Price/Product Name etc. I was looking to develop one report where all there fields are present as part of a dropdown. When the user selects one value such as Product ID and enters a value in the text box next to the ID, the report is filtered on this parameter. If the user selects name, the name can be entered in the text box and the report is filtered based on the Vendor ID etc.
Is there a way to do this? I have the parameters showing up next to each other instead.
It is doable if I understand correctly and here are the steps for achieving your report purpose.
I will use a simple query as an example data set for your reference.
1.Create source and datasets, in this example I skip the data sources and here is the short query for my exmaple
SELECT * FROM Table
WHERE
(ID = #ID or #ID = '')
and
(Name = #Name or #Name = '')
2.Add another dataset named Control, the query for Control is:
SELECT 'ID' as option
UNION
SELECT 'Name' as option
The purpose of creating this dataset is to provide the available values later when you need to choose either name or ID.
3.After step1, you should already have two parameters generated by system, which are ID and Name, if not, create them by yourself and go to each parameter page, DO MAKE SURE CHECK Allow blank value''
4.Create the 3rd parameter called Control, go to parameter setting page, go to Available Values, Choose Control dataset, Choose option (which is the customize column name you set in Controldataset) for both Value field and Label field
5.Go to ID parameter setting page, go to Default Values, choose Specify values, click fx, type this:
=Switch(Parameters!Control.Value="Name","")
Click ok
6.Go to Name parameter setting page, go to Default Values, choose Specify values, click fx, type this:
=Switch(Parameters!Control.Value="ID","")
Click ok
The ID and Name expression are correct, not set wrong
7.Change the parameter order to make Control on the VERY TOP, no matter ID or Name comes for the 2nd, but Control should be in the 1st place.
8.Drag and drop a table, place Name and ID. Preview the report, at this time, only Control will be available for you to choose value, choose either ID or Name to see the difference. When you choose ID, Name will be gray out, only ID light up and type any ID you want, actually, what the system does internally is passing the "" (blank value) to Name, that is why you need to make sure the Name parameter could accept blank value. Same for selecting Name
Update me if you have any run time issue
I'm new to Access so please consider this when forming your response. This has been driving me crazy and I've looked high and low on the 'net for a solution. I look forward to your response.
I have a form with an option group. I've wish to have this display on my report. Take for instance this "test" scenario:
Options
a, b, c
I've created a field in my table to accept the data from the form. In my table, I see 1, 2, 3 when I save a record. Good enough. Now, in my report, I have checkboxes representing options a, b, and c. I wish to have a checkmark within the box corresponding to the option selected on the form.
There's no technical limitation preventing you from displaying output on a report using an Option Group and check boxes.
In the design view of the report, add an option group control from the controls toolbox.
Add 3 checkbox controls to the option group control. When you select the check box control and hover the pointer over the option group, it will change color to indicate that the check box will become a part of the group when placed.
I added three check boxes to an option group on a report and they defaulted to values of 1, 2, and 3, so this should go pretty easily for what you're trying to do.
In the Property Sheet with the option group selected, make sure the Control Source property is set to the column with the 1, 2, 3 value in the underlying data source.
You might want to set the border style to hide the box around the checkboxes and also delete the label control that is automatically generated for the option group. I'm not sure what kind of look you're going for, but I'm sure you can handle the formatting details.
An option group is a user interface object, and UI objects don't belong on reports.
Your data field stores digits, but each of those digits has a meaning. On a report, you want the meaningful data displayed. That means that you need a data table that maps 1, 2 and 3 to something, and then join that table to the field you're storing the option group value in.
Another approach would be to use Switch(), but that means that you'd have to edit the report any time you add another option. A data table makes that a lot easier, as you just add a new record to add a new value.
