Hi Hristo,

Thanks for the reply.

Is there a way I can use a css or any code snippet to check the checkbox when it come to visible area atleast? (guess we can use the rowsrendered event to do this)

Actually in row changing event we are just selecting the rows based on Ids.

     preSelectGridRows =function ($grid, idsToBeSelected) {var dataView = $grid.data('igGrid').dataSource.dataView();

           var matchedRowIndexes = [];

           var key = $grid.igGrid("option", "primaryKey");

           if (idsToBeSelected.length > 0) {

                $.each(dataView,function (rowIndex, dataRow) {

                    $.each(idsToBeSelected,function (index, id) {

                       if (dataRow[key] === id) {

                            $grid.igGridSelection("selectRow", rowIndex);

                        }

                    });

                });

            }

        },

Now the only issue with the sample is we are unable to check the checkboxes even if the row is selected.

Thanks,

Veena

Hi Hristo,

We tried adding the code in Rendered event as well. One thing what I observed is "var dataView = grid.dataSource.dataView();" this will be [], so will not be able to get the actual grid data. I have attached a zip folder for reference. In that sample Please try keying in the value 70 in textbox and click on the Show Departments button.

You can see a popup screen where the departments are loaded, here when we scroll down to the row having department 70. you can see the row selected but the checkbox is not is checked state.

Please let me know if you require any additional information.

Thanks in advance for your support.

Hello Veena,

Thank you for your sample.

Regarding the Rendered event - in your current configuration the grid is initialized and rendered without binding to a data source, setting the datasource and binding comes later when you call the _loadAndBindData function. This is why in the rendered event you get returned an empty array.

 Could you please clarify why do data bind the grid in the _loadAndBindData function ? If you just set the dataSource of the grid when you initialize it and then call the _checkPreSelectedDepartments function right after the  _intializeDepartmentsGrid function, it works as expected.

Please check the modified sample I have attached and let me know if it fits your requirements this way.

Hello,
I am still following  your case. Have you been able to resolve the issue using the suggested ?
If you have any concerns or questions, please feel free to contact me, I will be glad to help you.
Thank you for choosing Infragistics components!

Hi Hristo,

I am working on the same code as veena posted. I tried the sample you have sent with the earlier post, binding the dataSource at grid initialization itself.

This still seems to be not working for higher number of rows. I added 10 more rows to the sample data and tried. The check box seems to be not checked for the selected row for row numbers >=90. Hope you will be able to provide a solution.

Thanks in anticipation!

Hello Irshad,

I have tested the sample attached in my last post with higher number of rows and it works as expected. I attach it again for you to check it.

I hope this helps.

Thank you.

Hi Hristo,

This workaround will not help us as we have some 900+ rows and the layout is fixed so that it should fit in one page. Similar issue we are also encountering while doing text search on department name field. As the text to be searched is not coming in visible area.

Please suggest if we can try any other alternative with Virtualization, preselecting the rows and checkboxes, search for the department name on IE10 browser.

Thanks,

Kiran

Hello Irshad,

I was using Chrome and it is okay, but I did see under IE it is not the same behavior.

The reason is that when using virtualization the DOM renders only the visible rows and some browsers have issues with this. Because the visible rows number is defined by the height of the grid, you can change the height of the grid. In my sample it is 380px, but give it try for example with 480px and it will work as expected.

I hope this helps.

Hi Hristo,

Thanks for your quick response.

I tried with your latest sample and the problem still persists. After row number 88 the pre-selected row doesn't have the checkbox checked.

I am using Internet Explorer 10. Are you using the same? Just a thought if it has anything to do with the browser version.

Thanks,

Irshad
