extjs pagingtoolbar refresh - javascript

I have a grid with local memory store. I can list the records in pages using pagingtoolbar. However, after filtering the data, I load filtered records to a new store and bind this store to the same pagingtoolbar. Then pagingtoolbar becomes disabled. In this state, when I check the pagingtoolbar's data it shows the correct values (total records and pages etc.). But the toolbar is disabled.
How can I update the view of paging toolbar?
Here some code:
var newStore = Ext.create('APP.myLocalStore', {
data: filteredStore.data,
totalCount: filteredStore.count()
});
pagingToolbar.bindStore();
pagingToolbar.bindStore(newStore);
pagingToolbar.moveFirst();
I am using extjs 4.x

You can use pagination bar refresh also. Try
Ext.getCmp('pagination bar').doRefresh()

DHTMLX Grid Pulling Additional Data

I am trying to build an app for users to submit their work times in but am having trouble with pulling additional data into the grid.
Eg: If a user were to type in there employee code of 0000 into the Employee Code Column the Employee Name Field would need to update to read "John Doe" All this data is stored in databases on the back end and I have been able to access it on refresh eg. If the page is reloaded after the new row has been created and the data is present it will pull the correct data in, but i do not want them to have to refresh the page to do this. How can I pull in the extra data after the cell has been updated.
The Grid is created on the page with JavaScript as follows:
timesheetGrid.setColumnIds("Column Names, Column Names");
timesheetGrid.setImagePath("codebase/imgs/"); //set the image path for the grids icons
timesheetGrid.setInitWidths("70,100,100,100,70,100,150,100,70,70,100,70,70,*,*"); //sets the initial widths of columns
timesheetGrid.setColAlign("center,center,center,center,center,center,center,center,center,center,center,center,center,left,left"); //sets the alignment of columns
timesheetGrid.setColTypes("edn,ro,dhxCalendar,ro,edn,ro,ed,ro,ro,ro,ed,edn,ch,txt,ro"); //sets the types of columns
timesheetGrid.setColSorting("str,str,date,date,str,str,str,str,str,str,str,str,str,str,str"); //sets the sorting types of columns
timesheetGrid.setDateFormat("%Y-%m-%d"); //Set the Date Format to be used in the Grid
timesheetGrid.attachHeader("#text_filter,#text_filter,#text_filter,,#text_filter,#text_filter,#text_filter,#text_filter,#text_filter,#text_filter,#text_filter,#text_filter,,,");
timesheetGrid.setColumnHidden(3,true);
timesheetGrid.enableEditEvents(true,false,true);
timesheetGrid.init();
//timesheetGrid.makeFilter("WeekEnding",0); //TODO: Add Filter For Week Ending
//this.lockRow(id, true); //Make Specific Row Read Only TODO: Non Active Week Rows Read Only
timesheetGrid.load("data/timesheets.php");
var dpg = new dataProcessor("data/timesheets.php");
dpg.enableDataNames(true); // will use names instead of indexes
dpg.init(timesheetGrid);
PHP is used to pull data from the correct avenues
require("../codebase/connector/grid_connector.php");//adds the connector engine
$conn = new GridConnector($res,"MySQL"); //initializes the connector object
if ($conn->is_select_mode()) {//code for loading data
SQL Code is HERE
}else { //code for other operations - i.e. update/insert/delete
OTHER SQL CODE IS HERE
}
As the Data is sensitive I cannot display any of it sorry for any inconvenience.
Any Help would be much appreciated.
If the data you're providing is XML you can attach an event to your grid and call this grid.updateFromXML("data/timesheets.php");
This will parse and paint the whole grid information
If you're looking to update just the row you updated you can send via GET the id of the row and it will only parse and paint the row you're sending
grid.updateFromXML("data/timesheets.php?for=" + row_id));
Full Code would be something like this:
dpg.defineAction ("update", myUpdate);
function myUpdate(tag){
timesheetGrid.updateFromXML("data/timesheets.php?for="+tag.getAttribute("sid"));
return true;
}
If the data you're retrieving is not XML formatted, I'm afraid you would need to update the values from the row manually via the same event.

Lightswitch load all data or run a async method synchronously

I have a grid with data in Lighswitch application. Grid has on every column posibility to filter column. Thanks to lsEnhancedTable
Right now I am sending an ajax request to the web api controler with the list of ids of the Customers that I want to export. It works but with a lot of data it is very slow because I have to turn off the paging of the data to get all visible customers ids so I can iterate over the VisualCollection.
To optimize this I would have to turn on back the paging of the data to 50 records so that the initial load is fast and move the loading of the data to a save/export to excel button.
Possible solutions:
Load data all data on save button click. To do this I have to somehow load all items before I can iterate over collection.
The code bellow locks UI thread since the loadMore is async. How to load all data synchronously? Ideally I would like to have some kind of progress view using a msls.showProgress.
while(3<4)
{
if (screen.tblCustomers.canLoadMore) {
screen.tblCustomers.loadMore();
}
else
break;
}
var visibleItemsIds = msls.iterate(screen.tblCustomers.data)
.where(function (c) {
return c;
})
Second approach would be turn on paging and pass just the filters applied by the users to the web api controller so I can query database and return only filtered records. But I don't know how to do that.
Third approach is the one that I am using right now. Turn off the paging->iterate over visual collection, get the customers id, pass them to the controller and return a filtered excel. This doesn't work well when there are a lot of records.
Iterate over filtered collection in the server side? I don't know if there is a way to do this in Lighswitch?
Here's an option for client side javascript.
// First build the OData filter string.
var filter = "(FieldName eq " + msls._toODataString("value", ":String") + ")";
// Then query the database.
myapp.activeDataWorkspace.ApplicationData.[TableName].filter(filter).execute().then(function (result) { ... });

Datatable client-side data change/redraw

I set up a datatables that initially gets from server some data and represents it, but then everything is left to the client. Some options are:
serverSide: false,
sAjaxSource: mySource,
My $.fn.DataTable.version is 1.10.2.
Then I need to change, client-side, the aaData under the table because some working on data is performed. I need to update the DT to show the client-altered temporary data without send another request to server (for two reason: prevent useless traffic and because that data is being altered).
I am looking for a way to edit the underlying DT databean to edit it, so then calling again
myTable.draw();
on my table I obtain a refresh realtime without sending another get to the server.
The question is, can I access DT data array, and can I edit it?
How is it done if is possible?
EDIT: I need to feed the table the full bean array as it initially took from the server, same format. So individual row/cell add/edit and client-side building functions are not suitable in my case, unless I manually cicle all objects.
SOLUTION
Use the code below:
// Retrieve data
var data = table.ajax.json();
// Modify data
$.each(data.data, function(){
this[0] = 'John Smith';
});
// Clear table
table.clear();
// Add updated data
table.rows.add(data.data);
// Redraw table
table.draw();

How to handle the huge data(>10 million) in sapui5 oTable?

I am using sap ui5 oTable for showing the huge data from hana db. While loading the huge data, the browser is going to crash.So I am fetching 100 records from db and showing the 20 records per page.So we can have 5 pagination(5*20=100) with one manual next button. If I click next manual button, I should get next 100 records and pagination should be 6,7,8,9,10.but i could not change the pagination no.
How to change the default pagination number in oTable?
How to achieve lazy loading concept in oTable?
Normally how to achieve the huge data handling in oTable?
Your question is a bit cryptic
Q: If you are asking, why does the odata call only return 100 rows at a time?
The ODataListBinding which populates the table uses the model size limit, which by default is 100, this number is then used in the OData Query populating the $top and $skip query options
eg $top=100 $skip=0
returning the first 100 rows only
Q: How do i change the size limit to bring back more than 100 records
oModel.setSizeLimit(999999)

How to get cookie value from jquery tablesorter, which stores sorting?

In JavaScript code of web application, the table sorter is defined by:
$("#my-table").tablesorter({
headers: {
1: {
sorter: false
}
},
widgets: ["saveSort"]
});
So when the page is refreshed the sorting of table is saved, but when browser is closed, the table backs to its original sorting. So what I want is to get how table is sorted and save it to database. Can someone suggest me how I can obtain the cookie(s), which stores how table is sorted?
Thanks
When the saveSort widget (demo) saves the information, it tests the browser for localStorage first, then if that isn't available, it falls back to saving the sort to a cookie. So, you can either use the function built into the widgets file like this:
var myTable = $('#table1')[0],
myLastSort = $.tablesorter.storage( myTable, 'tablesorter-savesort');
or if you are using Chrome, go to that page and press F12. now click on the resources tab and look under "Local Storage"
The value may look a bit confusing, but it's just a JSON format:
{
"/tablesorter/docs/example-widget-savesort.html": {
"0": {
"sortList": [ [0,0],[2,1] ]
},
"1": {
"sortList": [ [0,0] ]
}
}
}
And it is broken down as follows:
"/tablesorter/docs/example-widget-savesort.html" is the url of the web page
"0" or "1" would either be the table ID or the index of the table on the page
"sortList" contains the actual sort list value
So as you can see in the above data, it is saving sort information for two tables on one web page.
You could use jQuery to save a cookie with the sorted colum. The next time that page is loaded, use either jQuery or server-side logic to get the value of the cookie, and sort the appropriate column. This might be useful reading: Can jQuery read/write cookies to a browser?
