My grid has around 2500 rows in it and out of those about 400 of them are selected nodes.
So I loop through all the nodes and if their Id is in the Id of those 400 records, I want them to get deleted.
So I wrote this:
allItems.forEach(node => {
if(selectedItems.includes(node.data.id))
node.setSelected(false);
})
It works BUT it only deleted 27 rows at a time, instead of deleting all 400 rows. So I have to click my button one more time and it deletes the next 27 records etc.
Why is it behaving like this? How can I change it to delete all those 400 rows at once?
Your example code is very limited. But why don't you use the grid's internal api to query the selected nodes?
this.gridApi.getSelectedNodes().forEach(node => {
node.setSelected(false);
});
Try this:-
To select all rows and delete all selected rows:-
deletedAllSelectedRows() {
this.gridApi.selectAll(); //select all rows
const sel = this.gridApi.getSelectedRows();
this.gridApi.applyTransaction({remove: sel});
}
Note:- version 23.1.0 is required for applyTransaction. For lower
version use this.gridApi.updateRowData({remove: sel})

I created an ABAP CDS view from a dataset. This dataset contains data with a field "OrderID" (from order 1 to order 10000). Based on this field, OrderID, I would like to create 2 query views : one containing only data from order 1 to 20 and another one with order 50 to 70.
Therefore, I was wondering if there is an annotation to select the value I want to show/remove. I don't want to filter for performance reason.
Use a where clause, as described in the ABAP keyword documentation:
define view first_query_view as
select from your_base_view
{ ... }
where OrderID between 1 and 20;
define view second_query_view as
select from your_base_view
{ ... }
where OrderID between 50 and 70;
Annotations explain how views and the elements in them are to be used. They don't control how the data is retrieved, joined, or filtered.
I want to work with table records that is selected (Marked), Example - I have 10 records in table and i mark 5 of them. Expected - when i work with selected records, it should look only on that 5 records, not whole 10.
So far i have this code that selects all records:
while select Table
where table.JournalId == table.JournalId
Is there a way to make it select only marked records, not everything?
That select is writen in class. I need to get those marked records into that class where that select is writen...
You need to pass the formdatasource object into the class that is selecting the records, and then use the MultiSelectionHelper to loop through the selected records on the formdatasource.
In the example below, the object salesTableFormDataSource needs to be passed in from the form to the class you are using. Obviously replace that with whatever your datasource/table needs are.
MultiSelectionHelper selection = MultiSelectionHelper::construct();
selection.parmDatasource(salesTableFormDataSource);
SalesTable salesTable = selection.getFirst();
while (salesTable)
{
//do something with your table buffer.
salesTable = selection.getNext();
}
I am working on developing a web application feature that suggests prices for users based on previous orders in the database. I am using the MongoDB NoSQL database. Before I begin, I am trying to figure out the best way to set up the order object to return the correct results.
When a user places an order such as the following: 1 cheeseburger + 1 fry, McDonalds, 12345 E. Street, MyTown, USA... it should only return objects that are EXACT matches from the database.
For example, I would not want to receive an order that contained 1 cheeseburger + 1 fry + 1 shake. I will be keeping running averages of the prices and counts for that exact order.
{
restaurantAddress: "12345 E. Street, MyTown, USA",
restaurantName: "McDonald's",
orders: {
{ cheeseburger: 1, fries: 2 }
: {
sumPaid: 1444.55,
numTimesOrdered: 167,
avgPaid: 8.65 (gets recomputed w/ each new order)
},
{ // repeat for each unique item config },
{ // another unique item (or items) }
}
Do you think this is a valid and efficient way to set up the document in MongoDB? Or should I be using multiple documents?
If this is valid, how can I query it to only return exact orders? I looked into $eq but it did not seem to be exactly what I was looking for.
So I believe we have solved the problem. The solution is to create a string that is unique for the order on the server side. For example, we will write a function that would transform the 1 cheeseburger + 2 fries into burger1fries2. In order to keep consistency in the database, we will first sort the entries alphabetically, so we will always hit what we intended with the query. A similar order of 2 fries + 1 cheeseburger would generate the string burger1fries2 as well.
I need to divide with UPDATE command rows (selected from subselect) in PostgreSQL table into groups, these groups will be identified with integer value in one of its columns. These groups should be with the same size. Source table contains billions of records.
For example I need to divide 213 selected rows into groups, every group should contains 50 records. The result will be:
1 - 50. row => 1
51 - 100. row => 2
101 - 150. row => 3
151 - 200. row => 4
200 - 213. row => 5
There is no problem to do it with some loop (or use PostgreSQL window functions), but I need to do it very efficiently and quickly. I can't use sequence in id because there should be gaps in these ids.
I have an idea to use random integer number generator and set it as default value for a row. But this is not useable when I need to adjust group size.
The query below should display 213 rows with a group-number from 0-4. Just add 1 if you want 1-5
SELECT i, (row_number() OVER () - 1) / 50 AS grp
FROM generate_series(1001,1213) i
ORDER BY i;
create temporary sequence s minvalue 0 start with 0;
select *, nextval('s') / 50 grp
from t;
drop sequence s;
I think it has the potential to be faster than the row_number version #Richard. But the difference could be not relevant depending on the specifics.
I have a kendogrid. What I do is first filter it, which works fine.
After having it filtered, I want to select a specific row. I am sure I have the row in the result of the filter.
Example:
data = id=a1, id=a2, id=a3, id=a4, id=a5, id=a6
filter result:
id=a2, id=a4, id=a6
I would like to select the row a4.
First of all loop through the Grid's data which is currently displayed (i.e.
var arrayOfModels = $('#GridName').data().kendoGrid.dataSource.view();
next add the k-state-selected class to the row you want to make it selected
$('#GridName tbody [data-uid='+model.uid+']').addClass('.k-state-selected')
where model is the record from the arrayOfModels above which you need
