    I was having an issue where if the dropDownList is open when you start typing in the input box, the suggestion list appears on top of the dropDownList, rather than replacing it.

    Was able to reproduce in the demo application - attaching gif showing the behaviour.

    Any suggestions on how to avoid this, other than going with other autocomplete mode?


    Autocomplete mode is Suggest,

    Telerik version is 2020.3.915.40

    Hello, Marija,

    This is the default behavior in RadDropDownList, when the pop up that shows the data items is shown and you begin to type anything in the text box field the pop up that contains the suggested items to appear on top of the all items. However, if you want to close the item's pop-up when the suggestion list is shown you can achieve it as shown below:

    public RadForm1()
        this.radDropDownList1.AutoCompleteMode = AutoCompleteMode.Suggest;
        this.radDropDownList1.DropDownListElement.TextBox.TextBoxItem.TextChanged += this.TextBoxItem_TextChanged;
    private void TextBoxItem_TextChanged(object sender, EventArgs e)

    I hope this helps. If you have other questions I would be glad to help.
