Hi @naoto nakada ..can u upload the Oml for more explanation?

Or try this code(May be after updating the list not getting refreshed so i add refresh ).

let grid = GridAPI.GridManager.GetGridById($parameters.GridWidgetId).provider;

grid.beginningEdit.addHandler((s, e) => {

    var c = s.columns[e.col];

    var item = s.rows[e.row].dataItem;

    if (c.binding == 'Form.Test') {

        // Prevent the grid from entering edit mode immediately

        e.cancel = true;

        $actions.GetDropdownList(FilterValue1).then(function(result) {

            let Map = JSON.parse(result.DropdownList);

            c.dataMap = Map;

            // Refresh the specific cell or column

            grid.refresh(true); // Refresh the entire grid (or use a more specific refresh method if available)

            // Manually trigger the edit mode again

            grid.editCell(e.row, e.col);

            $resolve();

        }).catch(function(error) {

            console.error("Error fetching dropdown list:", error);

            $resolve();

        });

    }

});

Best Regards

Thanks for the reply!

I checked with the code you shared,

I got an error saying grid.editCell is not a function.

How can I resolve this issue?

Sorry for the inconvenience, but please check it out.

Hi @naoto nakada ,

can u share the oml,it is more helpful.

    var c = s.columns[e.col];

    var item = s.rows[e.row].dataItem;

        $actions.GetDropdownList(FilterValue1).then(function(result) {

            c.dataMap = Map;

            // Refresh the specific cell or column

            grid.refresh(true); // Refresh the entire grid (or use a more specific refresh method if available)

            // Try to programmatically re-select and enter edit mode

            setTimeout(() => {

                grid.selectCell({ row: e.row, column: e.col });

                grid.beginningEdit.raiseEvent({ row: e.row, column: e.col });

            }, 0);

            $resolve();

        }).catch(function(error) {

            console.error("Error fetching dropdown list:", error);

            $resolve();

        });

Sorry, we are unable to provide oml because we are checking in your environment.

I deleted grid.editCell(e.row, e.col); and checked again,

Dropdown listings no longer show anything.

$actions.GetDropdownList(FilterValue1).then(function(result) {... }); If I do this within $actions.GetDropdownList(FilterValue1).then(function(result) {...); the dropdown list seems to be empty.

Perhaps, but if I do it within $actions.GetDropdownList(FilterValue1).then(function(result) {... }); does not seem to update the set information when done within $actions.

$actions.GetDropdownList(FilterValue1).then(function(result) {... });; can the list retrieved by $actions.GetDropdownList(FilterValue1).then(function(result) {...}); be put outside in a form like resolve(Map);?
