I have following situation: grid1 and grid2. After user press at button I generate records for grid2 with help PXDatabase.Insert. I need PXDatabase.Insert due to performance reason, so please don't say I have to use view. How can I refresh grid2 without refreshing whole screen. For example grid has button refresh. How to call it automatically?
You can force application to refresh a grid by invoking RequestRefresh() on the view which is bound to your grid2. For example, in the discount calculation engine, you will find this code, to force system to refresh discount details grid:
discountDetails.View.RequestRefresh();

In my SAPUI5 application, I am facing a an issue with the refresh. There are multiple views like Orders, OrderInfo, OrderChange, OrderClose.
In the first view Orders, I have IconTabFilter to filter different types of Orders and I am using setCount to show the number in the IconTab Filter.
The problem is when I am on screen OrderClose where I close my order and I come back to the main view Orders using navigation, it shows me 1 order less but the IconTabFilter count does not change unless I do model.refresh() and model.UpdateBinding().
Ideally i want the count to change the moment I come to the view Orders from view OrderClose with updated count.
Can anyone help me out ?

Re-rendering control will solve this issue,instead of refreshing model or bindings.
Invoke rerender on control to be updated.
This triggers immediate rerendering of its parent and thus of itself and its children.
I'm using PagedFilterTable in Vaadin to manage pagination. When loading default page, I have set something like this - and I include sorting by some field:
if(this.sortField != null){
table.setSortContainerPropertyId(this.sortField);
table.setColumnWidth(this.sortField, 80);
table.setSortAscending(true);
table.sort();
}
So that happens when the page is loaded and that is fine. After I submit new entry (entries are being added through new, popup window), table gets new row, but the table loses it's sort order in view after popup closes, so sorting is no longer keeped. Problem is I do not know how to get to that table element from that popup window and set sorting again. Why table is being updated and I see it, and sort doesen't? Problem is bigger because I have both windows in separate files and seems to me I can't grab table element easily without modifiying the logic because I am in another window.
How to reload table so that the sort stays same?
I managed to do this after submit:
getUI().getPage().reload();
With that it works, but I am not satisfied. After that line of code, everything reloads again (meaning all queries execute again). Result is good but I don't want after submit whole reloading of page happens (also because none of my other buttons do reload). So I would like only to reload table in parent window.
How can I grab table object from outside window and for example set it's change to immediate and correct change?
Something like this I suppose needs to be written:
getParent().getUI().setImmediate(true);
?
Or better question, how to manage to table sort remains the same after inserting new entry through new window?
I managed to solve it. On the parent window in the windowCloseListener I just added:
myTable.refreshTable(data);
myTable.sortTable(); // my custom method that was Invoked on the page load too
I am using a kendo UI grid on a view, which is part of durandal 2.0 app using knockout for mvvm.
On a specific view, there is need to display a kendo grid having dynamic number of columns,
so every time view is visited, grid columns may have different count than the last visits.
Now as caching is enabled(applicable to this view too), so for subsequent visits grid rows are changing to reflect data change, but grid header(including number of columns) remains as it was during very first visit to view.
Note: if i disable caching for compose which is used to compose this view, grid loads fine with varying number of columns every time, but can't disable caching just because one control is not loading fine, and due to business needs.
so i wanted to know is there any way i can tell durandal to run viewattached event every time a specific view is visited, if not possible then is it possible that i can ask Durandal to recreate kendo grid control on every visit(so it doesn't uses what it created and having in cache of view)... i also tried always run viewattached on comose, but that brings a flicker when visiting the view hence i feel kind of disables caching for compose(but i can't do that a this compose is common for more than a view, which all should use caching)
Your viewmodel should return a constructor function instead of an object literal. But without seeing your code, it is difficult to identify your specific problem.
Looked many things up, but never posted before. Here's my situation. Any help would be most appreciated.
I've got a wizard with numerous screens with an associated navigation bar made using CSS. As users click from screen to screen, the navigation reflects the current wizard page the user is on. Each screen has different inputs to be collected. Database reads and writes are required during the render and submission of each page.
Here's the catch. Not every page is required. Only required pages are displayed in the navigation and the required information is stored in the database.
My goal is to reduce the number of database queries by dividing the navigation and remaining input into two separate partials. This way I don't have to render the navigation between each screen eliminating the single query every time between screens.
How would I submit the form of the current screen, render the partial view of the next screen, and yet update the query string to reflect the current partial view as well? This way if the user refreshes the page, they get the current screen.
Sounds like pre-optimization. How do you know you're going to have a problem with your navigation because of the database?
Why not separate out your navigation and output cache it?
If you bound determined to change the url without changing the content you need to use History API and if you need a fall back for browsers that don't support that you can use history.js.
I am currently working on a Customer Management application made in SmartGWT 2.0.
The Add Customer form is a fairly big one with multiple tabs and each tab has lot of fields. This form is opened in a modal window which have a save and a close button at the bottom.
Since this is a huge form, sometimes the rep accidentally hits Close without noticing that there is some information in one of the tabs.
We want to add some kind of alert when user tries to close the form after he has made changes to it.
I saw that there is ChangeHandler on text items which can flag a change which can be evaluated before firing the close event. However currently doing this for so many fields is a little bit cumbersome. Is there a way of achieving this on a DynamicForm level or even better on the Window level?
I am looking for a SmartGWT equivalent of this jquery code:
$("input:text, select, input:checkbox, input:radio, input:password").change(function(){
unloadRoutineFlag = true;
});
Take a closer look at this handler at the dynamicForm level.
addItemChangedHandler(ItemChangedHandler handler)
Handler fired when there is a changed() event fired on a FormItem
within this form.
Typically, when a formItem fires the changed() event, the form gets notified. Let us know if this works.
