keydown on mobile device


In my Blazor Server Web App that should work exclusively on mobile devices,

I'm trying to intercept the @onkeydown event.

Something like this:

<SfTextBox ShowClearButton="true" Autocomplete="AutoComplete.Off" Type="InputType.Search"
           @onkeydown="OnInputTextBoxKeyDown" />

The problem is that any keydown from a mobile device returns the followeing KeyboardEventArgs:

Am I doing something wrong?

Please provide any suggestions!

Thank you in advance!

Best regards,

Ivan Temelkov

Hi Ivan,

Greetings …!

"The onKeyDown event in mobile browsers may not provide the desired event arguments, such as the key code or character, due to the limited keyboard options on mobile devices. This is also the intended behavior in native <InputText> elements. An alternate solution for capturing keyboard input on mobile devices is to utilize the Input event, which is triggered whenever a user interacts with a Syncfusion TextBox."


@using Syncfusion.Blazor.Inputs



<SfTextBox ShowClearButton="true" Autocomplete="AutoComplete.Off" Type="InputType.Search"

           Input="OnInputTextBoxKeyDown" />




    void OnInputTextBoxKeyDown(InputEventArgs args)


        var key = args.Value;
