This knowledge base explains how to get the selected Records from all the pages in grid when using checkbox selection. We can get array of selected record index value with corresponding page information from the variable checkSelectedRowsIndexes of the Grid. Using the selected record index from that variable, we can get the selected records from model.dataSource (dataSource bound to the Grid). The checkSelectedRowsIndexes is a collection which holds the page Index and the selected record index of the corresponding page.
HTML <input type="button" id="GetRecords" /> <div id="Grid"></div>
JS <script type="text/javascript">
$(function () {
$("#GetRecords").ejButton({
text: "Get selected Records",
click: "getSelectedRecords"
})
$("#Grid").ejGrid({
dataSource: window.gridData,
allowPaging: true,
allowGrouping: true,
allowFiltering: true,
pageSettings: { pageSize: 4 },
filterSettings: {
filteredColumns: [
{
"field": "CustomerID", "operator": "startswith", "value": "vi",
"matchcase": false, "predicate": "and"
}]
},
groupSettings: { groupedColumns: ["EmployeeID"], showDropArea: false },
columns: [
{ type: "checkbox", width: 50 },
{ field: "OrderID", headerText: "Order ID", width: 75 },

We can get the selected record details in button click event after selecting all the records using checkbox selection. This will work only for the local data and not for the remote data. Since Grid will not aware of the other page records in the remote dataSource, it loads current data alone while pagination. If any other actions such as sorting, filtering, grouping has be taken place, we cannot get the selected records from the Grid dataSource. <script type="text/javascript">
function getSelectedRecords(args) {
var obj = $("#Grid").ejGrid("instance"), rec = [];
var check = obj.checkSelectedRowsIndexes; // collection which holds the page index and the selected record index
if (check.length) {
for (var pageInx = 0; pageInx < check.length; pageInx++) {
if (!ej.isNullOrUndefined(check[pageInx]))
rec = getRecords(pageInx, check[pageInx], obj, rec);
}
}
console.log(rec);
}
function getRecords(pageInx, inx, proxy, rec) {
var data = proxy.model.dataSource;
var cloneQuery = proxy.model.query.clone(), newQuery = cloneQuery.clone(), del = [];
cloneQuery.queries.filter(function (q, ix) {
if (q.fn == "onPage" || q.fn == "onGroup") del.push(ix);
})
for (var i = del.length - 1; i >= 0; i--) {

}
data = (data instanceof ej.DataManager) ? data.dataSource.json.slice(0) : data.slice(0);
data = ej.DataManager(data).executeLocal(newQuery).result;
if (inx.length) {
for (var i = 0; i < inx.length; i++) {
var pageSize = proxy.model.pageSettings.pageSize;//gets the page size of grid
var dat = data[pageInx * pageSize + inx[i]];
rec.push(dat); //pushing all the selected Records
}
}
return rec;

error : ejGrid: methods/properties can be accessed only after plugin creation
pls help!!!
Hi Sunil,
We have checked your query and we suspect that the cause of the issue is that you have created a grid instance in the document ready before the Grid control get rendered. So please ensure to create an instance after grid control has rendered.
If you still face the issue please get back to us with the following details.
1. Share the full grid code that you have used.
2. If possible please share the sample with issue reproducing.
The provided information will help us to analyze the issue and provide you the response as early as possible
Regards,
Manisankar Durai.
this produces the above issue
Hi Sunil,
We have checked the reported issue with the provided code example and we are not able to reproduce the reported issue.
We have also prepared a sample based on the provided code example and that can be available from the below link
Link: http://www.syncfusion.com/downloads/support/directtrac/196682/ze/angular2-seeds-systemjs508964927
We have also found that you have called getCurrentViewData() using grid element instead of getting from grid instance. We suggest you to modify the code as like below
public onClick(e: any) {
console.log(e);
var grid = $('#grid').ejGrid('instance');
var index = grid.getSelectedRows().closest("tr").index()
var record = grid.getCurrentViewData()[index];
alert('Record Details: ' + JSON.stringify(record));
}
Also we found that you are trying to get the selectedRecords in grid. To get the selected records we suggest you to use getSelectedRecords method in grid.
Link: https://help.syncfusion.com/api/angular/ejgrid#methods:getselectedrecords
If you still face the issue please provide the sample with issue reproducing.
Regards,
Manisankar Durai.
after implementing ur code , i still got the error : ejGrid: methods/properties can be accessed only after plugin creation
Hi Sunil
Before proceeding please provide us the following details.
1. Share the video demonstration of the reported issue that you have faced.
2. Share the stack trace of the issue from the console window.
3. You have called a method fetchClientList in ngOnInit. Share the code that you have used in fetchClientList method.
4. Share the sample with issue reproducing.
The provided information will help us to analyze the issue and provide you the response as early as possible
Regards,
Manisankar Durai.
