    I want to disable the user to set progress of the item less than the progress I inputted.
    Is there something like progressChangedEvent? Please help me.

    Hi Eljey,

    Thank you for writing.

    You can subscribe your RadGanttView object to the ItemChanged changed event. In the handler you can perform a check and if the value being changed is less than your minimum value display a message e.g.:
    int min = 20;
    private void CustomRadGanttView_ItemChanged(object sender, GanttViewItemChangedEventArgs e)
        if (e.PropertyName == "Progress" && e.Item.Progress < min) {
            RadMessageBox.Show("Invalid Progress");
            e.Item.Progress = min;

    Additionally you can also modify the context menu, please refer to the following article for details:

    I hope this helps. Should you have further questions please do not hesitate to write back.
