I have been using the PaginatedDataTable widget in flutter and am looking to add a search bar to filter down the rows based on the input
However there is no clear way to do this; most tutorials only show sorting the columns.
When I modify the RowData object that's passed into the source input of the table nothing happens.
Does anyone have any tips on what I'm missing?
Many thanks in advance.
Perhaps you are missing a notifyListeners after changing the data source?
Call this method whenever the object changes, to notify any clients the object may have changed. Listeners that are added during this iteration will not be visited. Listeners that are removed during this iteration will not be visited after they are removed.

I'm working with ag-grid I have a table that looks like the one provided HERE. In my own project, I am using an external api that will receive a real item. I need to update the Received Quantity after the done. Unfortunately, the api doesn't return anything other an a status code. So I can't do something like remove the row and a new row and this particular endpoint is also throttled heavily so I can't just refetch the list over and over to update it (which probably isn't a good idea anyway).
My plan was to just take the current value in Received Quantity and increment the cell myself. I can't seem to get it right and I just out of ideas of how I can possibly do that (I know it's probably simple by brain is just fried).
I'd really appreciate it if anything who's done this can help me out.
I ended up figuring this one out after a couple days not thinking about it. So I'll answer my own question for anyone who needs to know in the future.
I was trying to "edit" the data when I really needed to "update" it.
Essentially, every row in your grid will have a RowNode. You can access this node from the params of the row . Every is RowNode is indexed and has a setDataValue function which you can use to update entire rows or single cells. Click the update link above to reach the relevant documentation.
I am deleting row from a sheet, On a sheet I have daily job which needs to recognize the deleted records, I need a way to recognize them using smartsheet api or sdk..
Thanks in advance..
I don't believe this scenario (identifying deleted rows) is explicitly supported by the API at this time. Seems like you could still use the API to achieve your goal though, with a bit more work (code) on your part.
Your code would have to get the sheet data (i.e., all sheet rows) at a regular interval and save that data somewhere -- then each time job runs, get the sheet data again and compare that data to the data you saved the previous time the job ran (to identify any rows that had been deleted).
Edit 9/26: Added Webhooks info
Note that with the approach I've described above, any rows that had been added AND deleted during the interval between job runs would not be detected. If it's important to identify each and every time a row is deleted, a better (and much more efficient) approach would be to use Webhooks. By using webhooks, your application subscribes to notifications for a specified sheet, and then would receive a callback (HTTP POST) from Smartsheet any time the sheet changes. Your application would need to inspect the information in each callback it receives to identify 'deleted row' events (eventType = deleted and objectType = row).
A simple way to do this is to add a column with a checkmark named "delete" or something similar, then with automation you can move the row to another sheet when the flag is detected, the row will be removed from the original sheet, but you will have a record of the deleted row in a different sheet that you can read or do what ever you need to do, this will also prevent deletions by mistake and you can even restore the row back if you need to. I don't think you need much code to implement this solution.
I have a CheckBox in my TabPage on my Form, if I select the checkBox, the value is saved in a Table field (present in my FormDataSource: ParametersTable).
I want to refresh the form when I enter in TabPage, just Like pressing F5.
Is it possible?
There is a great article about different methods of refreshing the form's data here. Here are the basic outline:
1. Refresh
This method basically refreshes the data displayed in the form controls with whatever is stored in the form cache for that particular datasource record. Calling refresh() method will NOT reread the record from the database. So if changes happened to the record in another process, these will not be shown after executing refresh().
2. Reread
Calling reread() will query the database and re-read the current record contents into the datasource form cache. This will not display the changes on the form until a redraw of the grid contents happens (for example, when you navigate away from the row or re-open the form).
You should not use it to refresh the form data if you have through code added or removed records.
3. Research
Calling research() will rerun the existing form query against the database, therefore updating the list with new/removed records as well as updating all existing rows. This will honor any existing filters and sorting on the form, that were set by the user.
4. ExecuteQuery
Calling executeQuery() will also rerun the query and update/add/delete the rows in the grid. ExecuteQuery should be used if you have modified the query in your code and need to refresh the form to display the data based on the updated query.
I strongly recommand that you read the article. Try to use some of the methods above or some combinations of them.
Start with research() method, it might solve your problem:
formDataSource.research();
I am implementing tableView which loads data from server. I got two scenario:
Get complete data from the server and store in the array say 500 items. Now whenever I need those data I will call my array and fetch data accordingly. In this case, loading huge data from server at first time will take place.
Get required data say 15 from the server and store in the Mutable array. And, if User has scroll down ,get data from the server again and add those in mutable array and display those in the table accordingly. In this case, whenever user will scroll up and down, we have to call server like Lazy Loading.
So, which would be appropriate way to load table from server.Any Feedback will be appreciated.
I think you should be use Lazy Loading. Pull To Refresh.... tableview is available for that. every refresh get 15 records and add into your array. i think this is the best way. because if you load 500 items at a time and any user required only 5th item, so other record are not useful..so i suggested you to use 2nd way.
I think for better solution you can have a bottom cell named "Load more items", click on that cell will load next set of items, it will help both user and programmer for avoiding unwanted items.
When you bind to a Kendo UI Grid with MVVM, databound will fire once and all is well. If you need to update that data after the fact, every time you change one piece of data on any viewmodel (or child viewmodel), the entire grid re-databinds. Thus, if you had some cell in the grid that is bound to a template and you have to change 2 or 3 properties on the viewmodel from some external ajax source, Databound will fire 2 or 3 times for each model that is changed, causing the entire viewable area to rebind. How can we update lots of data at once and only have databound fire once?
How exactly you rebind the Grid? Basically if you change some of the models like this:
dataItem.set('SomeField','new value');
dataItem.set('someOtherField','other value');
This way the Grid will be indeed bound two times because of the MVVM. The change event is triggered each time you call set.
However if you update the values like this:
dataItem.SomeField='new value';
dataItem.someOtherField= 'other value';
The Grid wont react to the change and wont rebind re-read the values from the models you can force the Grid to do it through the refresh method.
$('#gridName').data().kendoGrid.refresh()
I'm not sure if there is some way to temporarily tell the grid to stop listening to events and then at the end, re-sync once. If there is, please give that answer here! Otherwise, what I did instead is I didn't go through .set() for each item. Instead, I updated the data for all the rows by setting the data directly to the property. Then when I got to the very last row I was updating, I called .set() on the last property that needed to be updated. This will cause databound to fire only once and the entire grid will refresh itself with all the data that was changed. If you don't do it this way, then the more rows displayed on the page, the longer it takes to process. (It could take 20+ seconds before the user can do anything again.)
It looks like the dataBinding event is where you can prevent a rebind on the grid.
