ListGrid: setCanSelectCells(true) Bug?

[zhene]

Hello,

I have a list grid that has these properties:

ListGrid grid = new ListGrid();
grid.setCanEdit(true);
grid.setCanSelectAll(true);
grid.setCanDragSelect(true); // these are what need to be tested
grid.setCanSelectCells(true);// these are what need to be tested
grid.setShowRecordComponents(true);
grid.setShowRecordComponentsByCell(true);

These drag and select features are awesome. The issue I run into is when I have a large data resultSet (lets say 100 records) in the grid and need to scroll, I select a record on the bottom of the grid but the grid scrolls to the top and the last visible record gets selected.

Steps to reproduce:
1) Fetch all data which requires scrolling.
2) Make an edit in of the top rows and save.
3) FOCUS OFF browser (click anywhere off the browser like selecting a file to view). Users do this all the time to view work from excel or downloaded files to compare with grid data...
4) Don't refocus but scroll down in grid to last record (very bottom and select a column)
5) This causes a refocus and grid will scroll to top and select the last visible record in grid.

This ONLY occurs when using setCanSelectCells(true).

Please let me know if you need anything else.

Hi Isomorphic,

out of interest I tried here (v13.0p_2022-09-14) with the following sample code and saw some warnings when scrolling.
This is not directly related to the OPs post, but perhaps related:

isc.ListGrid.create({
    ID: "dsListGrid",
    width: "100%",
    height: "100%",
    autoFetchData: true,
    dataSource: "supplyItem",
    showFilterEditor: true,
    alternateRecordStyles: true,
    // showRecordComponents:true,
    // canSelectAll: true,
    // canDragSelect: true,
    canSelectCells: true,
    cellSelectionChanged: function(cellList) {
        var cells = this.selection.getSelectedCells();
        displayForm.setValue("countries", isc.Comm.serialize(cells, false));
    }
});

isc.DynamicForm.create({
    ID: "displayForm",
    width: 250,
    height: 100,
    top: 250,
    fields: [{
        name: "countries",
        type: "textArea",
        width: "*",
        colSpan: "*",
        titleOrientation: "top",
        title: "Selected Cells"
    }]
});

isc.VLayout.create({
    ID: "vLayout",
    width: "100%",
    height: "100%",
    members: [dsListGrid, displayForm]
});

The warning I get is this and seems to be related to canSelectCells: true.

17:16:40.439:KUP6:WARN:ResultSet:isc_ResultSet_10 (dataSource: supplyItem, created by: dsListGrid):get: invalid index loading
17:16:40.440:KUP6:WARN:ResultSet:isc_ResultSet_10 (dataSource: supplyItem, created by: dsListGrid):get: invalid index loading
17:16:40.440:KUP6:WARN:ResultSet:isc_ResultSet_10 (dataSource: supplyItem, created by: dsListGrid):get: invalid index loading
