After expanding hierarchical grid, child grid row selection not returning row data.
posted

Hi, 

i used below link to manually expand and collapse hierarchical grid rows.

https://ko.infragistics.com/community/forums/f/ignite-ui-for-javascript/tags/igHierarchicalGrid

after expand has done i am trying to select element from child grid as follow :

var childGrids = $(this.element).igHierarchicalGrid("allChildren");
$.each(childGrids, function (ix, grid) {
selRows = $(grid).igGridSelection("selectedRows");
//selRows = $(grid).igGrid("selectedRows");
});

it returns empty array. due to which i am not able to set value to any cell as well.

var rows = $(grid).igGridSelection("selectedRows");

$.each(rows, function (ix, row) {

// getting the child grid selected row cell data
var rowId = row.element.data("id");
var cellValue = $(grid).igGrid("getCellValue", rowId, "Mycol");

});

    Hello Rupali , 

    Thank you for posting in our forum. 

    If you’re aiming to find the rows that were selected  in one of the child grids, then I suggest you check if the current child grid you’re looping through has selected rows and if does break the loop, for example:

     

    var selRows;

    var childGrids = $(this.element).igHierarchicalGrid("allChildren");
     $.each(childGrids, function (ix, grid) {
     selRows = $(grid).igGridSelection("selectedRows");

    if(selRows.length > 0){

    //breaks loop

    return false;

    }
    });

     

    Since the HierarchicalGrid does not allow different children to have selected rows only a single child grid can ever has selected rows at a time.

     

    Let me know if you have any questions .

     

    Best Regards,
