I have a page where I need to display projects from one table according to there status - I need To Do, In Progress, Done like on kanban board. I tried to filter each panel according to status but I guess because I filter the same datasource I end up with the same data in all three panels. Any advice? Thanks!
At least two options come to mind:
Use one datasource, but 3 tables, for each table, bind the Table Row's visible property to the item's status like: #datasource.item.status === "Done", etc. And then for the other two tables do the same but with a different status value, this will basically just hide the rows that don't match your desired status.
Use 3 datasources, and either have a query that loads a specific status, or let the user filter within that status using query filters (#datasource.query.filters.type._equals = "Done"). This way each table is its own datasource and set of records that does not overlap.

Currently my dropdownlist returns a value that I use in a SQL WHERE clause to return a result set. I would like to be able to just move to the selected record as oppose to filtering the whole set. When I filter I am no longer able to page through the records (I can only choose another search selection from the dropdownlist because there are no other records to page through - I would like to use both). What is the best way to achieve this?
This is truly baffling.
I have a subform that is set up as a continuous form and receives data from a query. Here is the SQL
SELECT Top 12 Tbl_Parent_ITN.ID, Tbl_Parent_ITN.ITN_Number, Tbl_Child_ITN.ITN,
Tbl_Child_ITN.Parent_ITN_fk, Tbl_Scope_Rqmts.Completed, Tbl_Scope_Rqmts.Child_ITN_fk,
Tbl_Lkup_Requirements.Requirement, Tbl_Lkup_Basis.Basis
FROM Tbl_Parent_ITN INNER JOIN (Tbl_Lkup_Requirements
INNER JOIN (Tbl_Lkup_Basis INNER JOIN (Tbl_Child_ITN INNER JOIN Tbl_Scope_Rqmts
ON Tbl_Child_ITN.Id = Tbl_Scope_Rqmts.Child_ITN_fk) ON Tbl_Lkup_Basis.ID = Tbl_Scope_Rqmts.Basis_fk)
ON Tbl_Lkup_Requirements.ID = Tbl_Scope_Rqmts.Requirements_fk)
ON Tbl_Parent_ITN.ID = Tbl_Child_ITN.Parent_ITN_fk
WHERE (((Tbl_Parent_ITN.ID)=[Forms]![Frm_Parent_ITN_Main]![parent_id]));
The criteria in the where clause of the SQL is passed based on the control in the form that precedes this form. The value is the primary key of the parent table that joins with several child tables to get all of the data for the subform.
When I open the with one record that has children it works perfectly fine and the form populates with 12 records. However, when I go run the same operation on the next parent record I don't get any results in view even though that parent has 4 child records.
What is really perplexing is that when I run the query independently from opening the form it gives me the exact results that I want based on that 2nd parent record. Furthermore, if I change the subform to a datasheet I still don't get any records; however, I can see the results in the filters of the datasheet form if I select those column headers (but no records show in the form itself). The properties of the subform are the exact same in both cases, so I can't understand what would cause the records to show in the 1st case but not the 2nd??
A few suggestions:
1. Try to do a Me.Refresh to see what happens.
2. Put a break point in the form's OnError event to see is there is something wrong.
3. Check if there is any other data source that may be locking any data that should be refreshed.
4. Verify that the no properties that define the parent-child relationship of the data is being changed during runtime.
5. Check if the parent record id gets refreshed on the OnCurrent event of the form.
Hope this helps,

I would really like to understand how to use the "count" property of the IconTabFilter for SAPUI5 to dynamically show the count of the result set of a table.
I have the following code -
<IconTabFilter
count="{DataSet/$count}">
<Table items="{DataSet}">
But the count is not filled automatically.
I am using an oData model that is bound on the view level. I do not want to make another backend request just for the counts. What am I doing wrong here? Is there a different mechanism that can be used?
I also tried using the updateFinished event on the table to then get the count and set it via JS but the event is triggered only on DOM placement of the table. In my case the table is hidden behind the IconTab and is not placed into the DOM till the first time the user clicks the tab so its useless.
Really would appreciate some insight into how to use this!
Thanks!
Okay, so what I did was I bound my information to a local model and did an oData $expand query to fetch the entire pages information in one call.
This worked out for me because I had several sets of data to be fetched. Before they were bound individually to tables, now they are all in one query.
In the .done() method of the call I just used the setCount method of the IconTabFilter to set the count as per the return data set.
I have a list of values in a SQL Table which are used to popluate a DropDownList, having a unique Integer as the value of each item and a String as the visible text (via SqlDataSource). There is also a third field in the database which is a flag to indicate whether the list item is active or not (inactive items are not shown in the DropDownList)
Selections made in the dropdown are stored in the database as their integer value (as part of a dataset making up the overall record), not the text value.
Over time, the items in the DropDownList may be removed by marking the items as inactive. However, there is still a need to open old records which may have had a now-inactive item as part of it's data...
My question is, what's the best way to ensure that the missing value included in the dropdown for the old record?
The two methods that spring to mind are to either:
Populate DropDownList with only the currently active items and, when loading a record, catch when the app tries to select a value that doesn't exist, go back to the db to see what it should be (the text value) and manually add it into the dropdown.
or...
Populate DropDownList with all list items (both active and inactive), load the record and then programatically remove all the inactive items (execpt for any that are now selected).
Neither of these seem particularly efficient, so I was wondering whether there is a best practice for this kind of thing?
there are so many optimum ways to do that sort of things, i am defining here a couple of them, use any of following if your Drop down list items count is less than 200 , lets say drop down list is of Products
1)
i) Load all Products records in drop down list and hide the inactive ones by setting visible=false
i) When you load a user record than look for its drop down list value if its visible than select it and enjoy, if its not visible than make it visible by setting its property visible=true and select it and also set its index or id in a flag to change its visibility(visible=false) again after your/users required operation performed.
2)
i) load only active Product records in drop down list ii) while loading a user record also load its product details(name, id, inactive_status) using Joins in sql.
iii) check in that user record if item is inactive then add its record in drop down list as you have all its details now with user details record else just select it.
IMPORTANT NOTE: if you drop down list has items in millions than use ADVANCE SEARCH techniques
The first thing I would do is question your business logic - should you be able to make an item inactive if it is being used as a foreign key in an active row elsewhere? If you make it inactive should it not remove all foreign keys as well?
To answer your question though I would go with a variation on the second idea but filtering in the page like that is probably slower than doing directly with SQL so I guess you have something like this at the moment to populate the dropdown
SELECT * FROM Table WHERE Active = 1
You should already have your record and the foreign key value so I would change it to this
SELECT * FROM Table WHERE Active = 1 OR PrimaryKey = [YourForeignKey]
Then you will always have the selected item but should also be fairly efficient.
I have a view with a filter by country. Country is an optional CCK text field with drop-down list selection from a predefined list.
When I expose the field as an optional view search filter, I can select a country on the filter form just fine, but how can I handle no selection? I want the user to be able to "un-select" any previously selected value so that the query runs for all countries (or, to be more precise, does not constrain the results by country). I cannot add "all" as a value to the CCK field for obvious reasons. Selecting all countries in the drop-down on the search filter is not very user-friendly and causes the page to time out (there are over 200 countries in the list, and I can only imagine the resulting SQL query). Whats the best way to handle this?
I found this View Filters Reset hack which could be helpful. The desire to memorize the last selection adds another complication - when configured in the View properties, and once the (persistent) cookie is set, there is no way to get rid of the selection (short of manually deleting the cookie).
The answer was to check "Force Single" on the filter properties. This made <any> show up as a selection in the country filter drop-down. It kind of makes sense, because <any> in a multiple-selection list could be seen as ambiguous. Still, I can think of valid reasons why a multiple selection filter might be optional. Drupal surprises me every day.
