    You can subscribe to one of these events:

    radGridView1.Columns["MyColumn"].ConditionalFormattingObjectList.CollectionChanged
    radGridView1.Columns["MyColumn"].ConditionalFormattingObjectList.CollectionChanging

    These will let you know when the conditional formatting collection has changed which doesn't happen until the user clicks apply. Also, it seems that this event is called twice as the Conditional Formatting Form clears the collection and then re-adds everything rather than add and removing objects from the collection. I have a post related to this here: How can I make conditional formatting read-only?

    I hope this helps. There may be a better way (such as subscribing to events on the Conditional Formatting Form itself) but I haven't figured out how to do this yet.

    Hello guys,

    Thank you for writing.

    @Barry
    The suggested solution by Chris is suitable to detect when you apply style formatting. You can determine whether the ConditionalFormattingObjectList is reset or a new setting is applied via the NotifyCollectionChangedEventArgs.Action argument:
    public Form1()
    {
        InitializeComponent();
        radGridView1.Columns["OrderID"].ConditionalFormattingObjectList.CollectionChanged
            += ConditionalFormattingObjectList_CollectionChanged;
    }
     
    private void ConditionalFormattingObjectList_CollectionChanged(object sender,
        NotifyCollectionChangedEventArgs e)
    {
        if (e.Action != Telerik.WinControls.Data.NotifyCollectionChangedAction.Reset)
        {
             
        }
    }

    @Chris
    I have updated your Telerik points for community effort.

    Hello Aref,

    Thank you for writing back.

    You can subscribe to the RadGridView.ConditionalFormattingFormShown event and change the Font property for the form and all its controls:
    Font f = new Font("Arial",14, FontStyle.Italic);
    private void radGridView1_ConditionalFormattingFormShown(object sender, EventArgs e)
    {
        RadForm form = sender as RadForm;
        form.Font = f;
        foreach (Control c in form.Controls)
        {
            c.Font = f;
        }
    }
     
    I hope this information helps. If you have any additional questions, please let me know.

    Regards,
