scroll bar does not work when dialog box appears in app designer

I am attaching the code, which is used to read the text files from the directory. whenever the dialog box appears the scroll bar as shown in the image freezes, is there any way i can scroll the text file names along with the dialog box open. Image and code attached.

        properties (Access = private)
        txt_files
        txt_DIR 
        txt_file_bas
        end
            methods (Access = private)

        % Button pushed function: UploadFilesButton
        function UploadFilesButtonPushed(app, event)
            app.txt_DIR       = 'C:\Users\Windows 10\Documents\samples\';
            app.txt_files = dir([app.txt_DIR  '*.txt']);
            b={app.txt_files(:).name}'; 
            app.TextArea.Value=app.txt_DIR ;  % Sets the label text to be the selected path
            b(ismember(b,{'.','..'})) = [];      % Removes unnecessary '.' and '..' results from the display.
            for txt_i = 1:length(app.txt_files)
                s_no{txt_i}=(txt_i);
            end
            s_no=s_no';
            app.UITable.Data=[s_no b];                  % Displays the directory information to the UITable.
            txt = inputdlg('Enter text value',...
             'Enter text value', [1 50]);
           
        end

        % Value changed function: TextArea
        function TextAreaValueChanged(app, event)
            value = app.TextArea.Value;    
        end
    end

inputdlg creates a modal dialog box. "Modal" means that no other window can be interacted with while the modal window is up.

To allow interacting with other windows while the inputdlg window is up, you can make the inputdlg non-modal:

txt = inputdlg( ...
    'Enter text value', ...             % prompt
    'Enter text value', ...             % title
    [1 50], ...                         % dimensions of edit field
    {''}, ...                           % default answer
    struct('WindowStyle','normal'));    % options
