Hi
Roman,
Thanks
for using Syncfusion products.
Query 1: I need to
select multiple items from a grid, but when i change the page of the grid, the
selection from the previous page disappears. How can I prevent it?
Based
on your requirement we have created the sample and the same can be downloaded
from the following link.
Sample Link: MVC_Sample_-_12.3.0.36.zip
In
the above sample we have used “_selectedRowsIndexes”
for getting selected rows of the current page in ActionBegin clientside event of the grid.
Please
refer the below code snippet.
|
@(Html.EJ().Grid<object>("Grid")
. . . .
}).ClientSideEvents(eve => { eve.ActionBegin("begin").ActionComplete("complete"); })
)
<script type="text/javascript">
function begin(args)
{
if (args.requestType == "paging")
{
var
gridobj = $("#Grid").data("ejGrid");
for (var i = 0; i < gridobj._selectedRowsIndexes.length; i++) {
selectedRecords.push({ rowIndex: args.previousPage,
selectedRecordsIndex: gridobj._selectedRowsIndexes[i] });
}
}
}
</script>
|
And
also in the ActionComplete event of
the grid we have selected the rows by passing the selected indices in to the selectRows method of the grid.
|
<script type="text/javascript">
function complete(args) {
for (var i = 0; i < records.length; i++) {
gridobj.multiSelectCtrlRequest = true;
gridobj.selectRows(records[i]);
} }
}
</script>
|
For
your kind information, In our current implementation we don’t have public
property for “_selectedRowIndexes” private variable and also we have
confirmed that an issue with “Need public property for _selectedRowIndexes private
variable” is a defect and also please create a new incident for better
follow up.
Query 2: One more
question: how can I get all records from the grid?
We
can get all the records from the grid using “dataSource” property as follows.
|
<script type="text/javascript">
function begin(args)
{
var data = args.model.dataSource;
}
|
Please
try the sample and let us know if you have any queries.
Regards,
Gowthami
