I'm using this method igGridSelection('selectedRows') to get the selected rows, but it does not return all the selected rows when using the grid's paging feature. It looks like it only returns the selectedRows for the current page. I'm using the EnableCheckBoxes feature to display a checkbox on the row, and I would like to get all the rows with the checkbox checked on all the pages.
Thanks

hi Martin,
I came across weird problem while using SelectionPersistence.js for filtering.
Here are the steps to reproduce problem.....
1. Selection a row
2. Filter(remote))(enter some characters in filter text box for any column)
3. Remove text from filter text box
4. Try to deselect a selected record.
5. I get the error when deselection row at row index 1:
Unhandled exception at line 366, column 12789 in http://cdn-na.infragistics.com/jquery/20132/latest/js/infragistics.lob.js
0x800a138f - Microsoft JScript runtime error: Unable to set value of the property '1': object is null or undefined
6. I do not get this error when I user selection with sorting. It is coming only with filtering.
7. I used IE 9(standard mode)
Here is my sample code
@(Html.Infragistics().Grid(Model.Customers.AsQueryable()) .ID("myIGrid") .Width("400px") .Height("300px") .AutoGenerateColumns(false) //.ResponseDataKey("Records") .PrimaryKey("ID") .Columns(column => { column.For(x => x.ID).HeaderText("ID").Width("20%"); column.For(x => x.Name).HeaderText("Name").Width("60%"); column.For(x => x.IsActive).HeaderText("IsActive").Width("20%"); }) .Features(feature => { feature.Sorting().Type(OpType.Remote); feature.Selection().Mode(SelectionMode.Row).MultipleSelection(true); feature.RowSelectors().EnableCheckBoxes(true).EnableRowNumbering(false); feature.Filtering().Type(OpType.Remote); })
.DataSourceUrl(Url.Action("GetAllC")) .DataBind() .Render() )
Rajesh Varade said:Can you please let me know how to find out total number of selectedRows in a grid while paging is enabled?
In the SelectionPersistence object I've exposed selectedRows API which will return all the PK values of the selected rows regardless of their visibility. You can then use the PK values with the igGrid.findRecordByKey in order to find the whole record from the data source. Please note that the igGridSelection.selectedRows API will return DOM TR elements, while the SelectionPersistence.selectedRows API will return only the PK values. That's because the invisible rows (when Paging is enabled) will not have DOM elements.
Hope this helps,Martin PavlovInfragistics, Inc.
Hello,
Can you please let me know how to find out total number of selectedRows in a grid while paging is enabled?
As of now,
$("#myGrid").igGridSelection("selectedRows");
returns only selected rows on current page.
Thanks,
Rajesh
hello Martin,
It worked for me. Thank you very much.
I have an issue in using rendered and destroy events. how to define them with HTML.Infragistics helpers ?
As of now I added below code just after my grid definition block which is defined using HTML.Infragistics helpers.
var sp; $(function () { $("#Grid").igGrid({ rendered: function (evt, ui) { sp = SelectionPersistence(ui.owner); sp.enable(); }, destroy: function (evt, ui) { sp.disable(); } }); });
Thank you,
