    I am using a dropDownList to show some values in order to filter results on a grid.

    I have use the 'change' event to see when the grid must be updated

    change: onModeSelectorChange


    in the method onModeSelectorChange I am trying to show the progress bar with

    kendo.ui.progress($("#grid), true);

    and at the end of the method when all is done I have

    kendo.ui.progress($("#grid), false);

    But the data loads and I do not see the progress bar.

    If I remove the last statement (the 'false' one) I can see the progress bar, but it never disappears.
    If I debug, It appears and disappears when the data is ready.

    It is not an issue of the data loading too fast, sometimes the data takes 5 seconds to be ready.
    The data is already in the browser, I am just showing or hiding columns.

    Kendo version v2016.2.714

    Hello Alban,

    On the following Dojo example you will find a working example of a Kendo DropDownList, which uses the change event to dynamically replace the DataSource of a Kendo Grid. You will notice that I have toggled the loader immediately after the change event of the DropDownList is triggered. The important part here is that in order to properly hide the spinner, I have used the dataBound event of the Grid. This way you guarantee that the timing of the toggle function will be correct.
