RadDropDownList: AutoCompleteMode.Suggest's popup is closed when using VirtualKeyboard

Hi,

 

When using a RadDropDownList component and the RadVirtualKeyboard component I have a problem. The AutoCompleteMode.Suggest works fine the first time I click on RadVirtualKeyboard but for the other clics the suggested items don't appears on the screen.

 

Regards

   Gilles

Hello, Gilles,

You can use a boolean flag to control when the PopupClosing event to be cancelled or not. Please refer to the following code snippet which result is illustrated in the attached gif file: 
        public RadForm1()
        {
            InitializeComponent(); 
            this.radDropDownList1.AutoCompleteMode = AutoCompleteMode.Suggest;

            this.radDropDownList1.DropDownListElement.AutoCompleteSuggest.DropDownList.PopupClosing += radDropDownList1_PopupClosing;
            this.radDropDownList1.DropDownListElement.AutoCompleteSuggest.DropDownList.ListElement.MouseDown += ListElement_MouseDown;
        }

        bool shouldCancel = true;
        

        private void radDropDownList1_PopupClosing(object sender, RadPopupClosingEventArgs args)
        { 
            args.Cancel = shouldCancel;
            shouldCancel = true;

        }

        private void ListElement_MouseDown(object sender, MouseEventArgs e)
        {
            shouldCancel = false;
        }

Note that this is just a sample approach and it may not cover all possible cases. Feel free to modify and extend it in a way which suits your requirements best.

I hope this information helps. If you need any further assistance please don't hesitate to contact me. 

Should you have further questions please let me know.

Thanks for your answer, it's work but the problem now is that the popup is always visible on screen. If I select a item value, the popup don't close ...

Hello, Gilles,

Indeed, the popup with suggestions will be closed after the first click on RadVirtualKeyboard.

I have logged it in our feedback portal by making this thread public. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

 

Currently, the possible solution that I can suggest is to cancel closing the suggest's popup:

        public RadForm1()
        {
            InitializeComponent();
            this.radDropDownList1.AutoCompleteMode = AutoCompleteMode.Suggest; 

            this.radDropDownList1.DropDownListElement.AutoCompleteSuggest.DropDownList.PopupClosing+=radDropDownList1_PopupClosing;

        }

        private void radDropDownList1_PopupClosing(object sender, RadPopupClosingEventArgs args)
        {
            args.Cancel = true;
        }

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
