I have a table created with DataTable of Google Chart, which has a column with a drop-down list. In this way the user can set the proper value of a row.
I am working in Python and Flask and I can retrieve the request data correctly. The problem is that the table, given the amount of data, is showed in pages, each one with 20 rows. When I retrieve the request I get only those 20 rows, so I have no way to know what the user set in the other pages.
How can I get the values of all pages?
Moreover, I noticed that when I change page and then I go back, the table forgets the user changes, so I think I should be careful also to this fact.
Finally, I solved the problem by using a dictionary containing all the changes made to the table and updating the html string inside the table to keep the content updated.

I'm using SlickGrid in a sharepoint environment to display and update data. To save on the the load time, I am populating auto complete fields with options that have only been used in previous lines (with tables with more than 50 lines), and then I am wanting to give the user the option to click on a "Metadata refresh button" located at the top of the autocomplete fields that will go and fetch all available options to repopulate the auto complete field.
<table><tr><td>[ TextField ] </td><td>[ AutoComplete1 ] </td><td>[ AutoComplete2]</td></tr>
<tr><td>Entry1</td><td>Hello</td><td>Goodbye</td></tr>
<tr><td>Entry2</td><td>Hi</td><td>Later</td></tr>
</table>
So if, the user was to create a new line, they would have the options of Hello and Hi in column 2, and Goodbye or Later in column 3 to choose from since they have been used before. If they want the option "Hail!" to appear in column 2, they would have to click the "Update MetaData" button for column 2, which would refresh ALL the cells in that column with all available but previously unused selections.
I know its not ideal, but its a requirement that has been given to me.
I know how to add buttons to column headers and I am updating the array of data that the grid needs for the autocomplete column, but I am at a loss on how to update the column choices without redrawing the whole grid.
Any suggestions?
Check out the newer examples in my repo: https://github.com/6pac/SlickGrid/wiki/Examples
This is probably closest to what you want:

What I have done in the past is create a data property of the cell node to store the object, like:
$jqacContainer.data('queryautocomplete', jqac);
It's then easy enough to get the object from the cell node.
However, this requires proper cleanup of the property to avoid a memory leak. This should be able to be done in editor.destroy(), but I don't think I've checked corner cases, for example where the editor is scrolled offscreen before being completed.
Is there another way to change how many rows are shown in the table other than overwriting the list.blade.php file?
It's a little-known API method, but you can do that by calling this in your EntityCrudController:
$this->crud->setDefaultPageLength(10); // number of rows shown in table view
A lot of time has passed. At the moment with the current version of Backpack (v 4.1.X) there is a setting in the configuration file in config/backpack/crud.php named defaultPageLength that controls the page length globally. If page length for a single CRUD controller should be changed, then $this->crud->setDefaultPageLength(50) is still the way to go.
More details can be found here: https://backpackforlaravel.com/docs/4.1/crud-api#page-length
I have some code that allows the user to perform a search by selecting a few checkboxes. A sql query is then created based on what checkboxes are checked. (Up to 5 checkboxes)
The data is then queried against a sqlite data.
The issue is now how do i populate the data into a listview (not knowing how many columns there will be ahead of time (Could be anywhere from 1 to 5)
All the examples I"ve seen is where the listView is created and you know exactly how many colummns are going to be returned.
A previous posted suggested to query all the records and then use if statements to determine if the value is null then hide column.
So I have a form in Access.![acessform1][1]
Here are form properties
I got this database and have been making adjustments to the other forms. I gave the database back to the user and they reported an issue that this form is not acting properly, and the add order record function is not working anymore.
There's an Add Order Record button on the right side of the form that would usually add the record if the user manually entered input into some of the boxes. The old form you would have control of the values 1/0 for yes/no. You can enter text into the notes boxes.
This functionality doesn't work anymore, and I can't seem to figure out why. The form is identical to the original and no adjustments have been made except to the table that it pulls data from.
So the symptoms are:
User input is not accepted in text boxes.
The find CP functionality works with the drop down and reflects the records accurately but I cannot update the fields.
Also, the fields CP_Ref and Invoice date don't let me enter data anymore.
Also the Add Order Record was giving me an error that The it could not find the record specified, but I since copied the original form back into place and that error went away.
I think functionality wise this button should save the record after a field is updated and should add a new record.
Seems like all the controls are locked on the page.
Here is the query that pulls the data when I click the button that takes me to the Order form.
SELECT DISTINCTROW CPOrders.Cust, Customer.NAME, CPOrders.CP_Ref, CPOrders.Slsman,
CPOrders.Date_opn, CPOrders.CPSmall, CPOrders.InvIssu, CPOrders.InvNo,
CPOrders.InvDate, CPOrders.DueDate, CPOrders.ETADate, CPOrders.Closed,
CPOrders.Cust, CPOrders.Name, CPOrders.BuyerRef, CPOrders.ToCity,
CPOrders.ToState, CPOrders.ToCtry, CPOrders.ToPort, CPOrders.Supplier,
CPOrders.Origin, CPOrders.Product, CPOrders.GradeType, CPOrders.NoUnits,
CPOrders.Pkg, CPOrders.Qty, CPOrders.TotSale, CPOrders.TotCost,
CPOrders.GrMargin, CPOrders.[Sale$/Unit], CPOrders.[Cost$/Unit],
CPOrders.OceanCost, CPOrders.OceanNotes, CPOrders.BLadingDate,
CPOrders.USAPort, CPOrders.FOBCost, CPOrders.FASExportVal,
CPOrders.InlandFrt, CPOrders.CommodCode, CPOrders.Notes,
CPOrders.ProjCust, CPOrders.ProjValue, CPOrders.ContainerNumber,
CPOrders.Vessel, Customer.TERMS
FROM Customer INNER JOIN CPOrders ON Customer.[CUST_#] = CPOrders.Cust
ORDER BY CPOrders.CP_Ref;
I ended up checking several locations for the answer to this.
What it ended up being was a primary key issue.
Essentially when I got the updated database I put them into new tables, effectively destroying the dependencies, relationships, and established keys.
I reverted back to the old tables and found out the form worked properly.
The issue ultimately was that the primary keys were not defined as needed for the table to be updated.
Basically, I want to insert rows in the form InventJournalTransfer. I added a menuitem button that calls a class which opens a dialog where I fill a WMSLocationId, then I loop on Inventsum table to get all ItemIds with Available qty for this WMSLocationId and insert them into InventJournalTrans Table.
The code I wrote seems to be working as I have correct records inserted in my table(visible in Table browser, correct journalId, linenum itemId, qty etc...) BUT the records inserted do not appear in my form. I tried to refresh my form with or without code, but my grid's still empty.
I had a look at the class InventCountCreate that does what I want to do in a different journal type, but as I'm quite a newbie it is difficult for me to understand exactly how this class works.
Could anyone explain to me how to display my inserted rows in my form or give other leads?
The InventJournalTrans is table is inner joined to two InventDim, one related via the InventDimId field, the other via ToInventDimId.
Both fields must be filled with a valid InventDimId to an existing InventDim record for the form to show the record.
Have you tried right-clicking on your form's node in the AOT and clicking "Restore"? Perhaps your form is still using cached data.
