For Ex: I have 5 existing lines as line no "1,2,3,4,5" and now i am trying to add one more row as "6" and try to save then the rows are shifted around while saving records through "Add rows" Button as "4,3,5,6,1,2" in interactive grid oracle Apex, the rows are automatically shifting the order, how to resolve this
In a relational database, rows in a table aren't "sorted" in any particular order. The only way to make sure they will be sorted properly is to apply the ORDER BY clause.
As you can't do it in Interactive Grid's query (if you used it), you'll have to do it through Interactive Grid's Actions button (Data > Sort) and choose one (or more) columns which will sort rows in the Interactive Grid.

When transforming from pivot longer to pivot wider many columns are created during intermediary steps, while debugging. for me it is easier to use the GUI, while i transform the data when checking for errors because in many instances it does not fit into the R console. Therefore, I would like to filter a column in the GUI and have the row or filter remain static, while using the "Cols: >> button".
Because i am a new user i cannot paste the R GUI Editor window to show the steps visually, however, i will write them in chronological order.
1.
Filter a column by ID "134"
2.
use navigation GUI button Cols: ">>" to page right for more than 50 columns in the data set.
3.
arrive at column 100 with filter applied. Displaying the subject filtered by ID "134".
This seems basic but i couldn't find a post about it. thnx
I am trying to create an expandable grid in MVC3. This is a follow up question to this .
Basically I have a complicated sql query that I need to use to populate a set of fields in a grid in MVC3. Also the grid elements must be expandable and on expansion should show additional data.
For example
I have two sql queries
Query A
select * from large tables joined
Query B
select data from selected row in query A
Query A represents my first query which I should use to populate the grid. On expansion of the grid I have to show the additional data by expanding the row from A with the query B.
I am creating a view model with all the fields I need in the first row of the grid that I can pass to the view.
Questions:
1.) How do I directly use sql to pass the data into the views instead of joining the models
2.) How do I make the grid expandable to show additional data?
3.) How do I model my sql, do I create one query for both and then selectively show data?
Caveat: MVC3 noob

Questions:
1.) How do I directly use sql to pass the data into the views instead of joining the models
This depends, either you pass in everything up front and write out hidden fields, or a hidden JSON object containing all the data and when the field is expanded, show it. so that is: Render all the data in your grid and hide each item until you need it, or dynamically load it from an array and show it when the user expands. You could also dynamically grab the required data when a user clicks on a row, but then you'd need to show a wait image while you grab the data by ajax (which would be fairly easy with mvc)
2.) How do I make the grid expandable to show additional data?
Plenty of expandable html grid results on the net :) Depend show you want to hide/show it.
3.) How do I model my sql, do I create one query for both and then selectively
This depends on the approach in 1 above. If you use ajax, you'd be returning one row at a time. In the other scenario you can have two queries you then merge into two view models or you join query A results with query b if theres a 1-1 mapping, assuming there isn't though so make two calls. Again, this is up to you. Do you want to pass all that data up front if the user will only expand two rows? not likely, in that case I like the ajax approach.
I have a grid with 10 columns, and another with over 60. I want to offer a view of these grids where any column or number of columns can be selected to remain visible. Then submit a request to hide all of the remaining 'UN-selected' grid columns, leaving the selected columns viewable.
End-users need to have a mechanism where they can choose which column(s) to view and the remaining columns will be hidden temporarily from view. I know that I can choose each column from the context menu to hide each column, but if I have a grid with multiple columns it can be quite difficult to select each column to hide. I would like to create a mechanism where users can select which columns they want to 'view' and allow the remaining columns to hide.
I believe that grid reconfigure may be the way to go, but there are no real examples showing how I might select the columns to allow viewable "on-the-fly", and then reconfigure the grid based on the new column model.
There are a couple of ways you could approach this:
One way would be to loop through the columns and call hide() method on those you wish to hide.
For a large number of columns it might be better to use reconfigure method. using reconfigure with the first paremeter undefined you get to reuse the store that was originally configured:
reconfigure( undefined, myColumns )
I'm trying to implement multiple record selection feature on a grid.
It is very similar to http://www.tek-tips.com/faqs.cfm?fid=3831
It adds an extra column with check boxes. I want those check boxes!!
But it depends on a extra logical field in the underlying table. It need to create a class clscheck which inherits CHECKBOX. I'm not sure why this CLICK procedure is needed for the checkbox.
PROCEDURE CLICK
IF DODEFAULT()
KEYBOARD '{DNARROW}'
ENDIF
ENDPROC
When I removed it, row selection did not work correctly as expected. Why this?
Here is my requirement:
1) I don't want to add an extra logical field in the underlying table.
2) To work with controls in the grid, I think AllowCellSelection must be .T. I want AllowCellSelection = .F. because I don't need to work with any control in the grid except the check boxes. I need to work only with check boxes. The other columns will be read-only.
3) Can I have selected list without the logical field in the underlying table?
4) Can I remove the usage of KEYBOARD '{DNARROW}'?
In fact, I have a grid which is AllowCellSelection = .F., but it only provides single selection.
I need to enhance it with multiple selection, thus, I just want to add an extra column with check boxes so that user can know he can select multiple records.
No need Shift+Click or Ctrl+Click which is not familiar with idiot users.
I have found this - http://www.tek-tips.com/faqs.cfm?fid=433
It also depends on an extra logical field and it depends Shift+Click and Ctrl+Click.
What you are seeing is quite common for multi-select grids. I've used them SIMILAR to this in the past. However, you are afraid of the extra column in the underlying table. That may/not be true. You don't always have to update the ORIGINAL table, but a temporary CURSOR you are presenting to the user. Ex: If you want to display a list of employees in a table. No, you don't want to keep adding this column to the original employee table as then anyone else trying to do multi-select could falsely get your selection. However, if you pulled into your own local cursor and presented to the user, then no problem. Example...
Thisform.YourGrid.RecordSource = "Employees"
(bound directly to your employee table -- not necessarily the right thing)
vs
use in select( "C_MultiPickEmployees" )
select ;
.F. as IsChosen, ;
E.* ;
from ;
Employees E;
into ;
cursor C_MultiPickEmployees READWRITE
Thisform.YourGrid.RecordSource = "C_MultiPickEmployees"
NOW, you have your extra column without dealing with issues to the underlying table. If you wanted to further filter what you were showing -- such as employees for a certain division/department, then just add that to a WHERE clause, add an Order By if so needed and you are good to go.
As for the "Allow Cell Selection", I've never had to deal with that. I just add a "checkbox" to the first column and set
Thisform.YourGrid.Column[1].CurrentControl = "CheckBoxControl"
(based on the name it is added to the column).
Then, set the column 1's "ControlSource" = "C_MultiPickEmployees.IsChosen" and you should mostly be done.
As for the "CLICK" event trying to force the down arrow. This is more for automatically scrolling to the next record so you can just click, click, click for multiple entries.
Hope this helps clarify things for you.
Does anyone know a way to have all the rows of one column of a repeating table to always have the same value?
Say the user changes the value in the first row for that column, then all the other cells in that column change to have the new value. (Preferably this will happen if a user changes any cell in the column, not just the one in the first row, but just the first row would be fine if that's all that's possible).
I have access to both InfoPath 2007 and InfoPath 2010 so can use either. The form submits data to and receives data from an SQL Server database. Code is fine if this requires it.
You basically want to change the field from a repeating field to just multiple copies of the same field (since you want it to always be the same there is no point in storing multiple versions).
On the data source tab, all the fields that you put in the repeating section are in a group folder with the little repeating icon on it. Right click on the field you want to be non repeating and choose move. Put it anywhere outside the repeating group folder (the encompassing folder is usually a good choice but it can be anywhere). The field on the design surface will now show a little info box that says "this item can't be repeated" (or similar).
Now you just have multiple copies of the same field - so if you change any one of them they will all update to reflect the value.
