RadzenDatePicker - Ability to hide virtual keyboard when date selected (mobile devices)

[paulo-rico]

When using the RadzenDatePicker component on a keyboard-less device, the virtual keyboard will automatically display when a user has clicked a date, the popup has closed, and the manual entry field gets focus.

I would like to add in the ability to turn this "auto show" off if desired.

My proposed solution is this -

Add a bool property in RadzenDatePicker.razor.cs to control whether the virtual keyboard automatically displays or not -

        /// <summary>
        /// Specifies whether the virtual keyboard on keyboard-less devices is shown when input is focused.
        /// </summary>
        /// <value>True or False (default)</value>
        [Parameter]
        public bool HideVirtualKeyboard { get; set; } = false;

Then, add the following to the <input @ref="@input"... element of RadzenDatePicker.razor -

virtualkeyboardpolicy="@(HideVirtualKeyboard ? "manual" : "auto")"

If this looks acceptable, I can put this into a PR.

Regards

Paul
