Passing Parameter On Focus event

Hi Team,

Can we pass Parameter in Onfocus event. I tried it in sfTextbox but it's giving me an error.

I need something like this

It would be a mess if I put method for each textbox.

Hope you can help me.

Best Regards,

Hi Tyrone,

We suggest you use the native focus event to achieve your requirement.

Find the code example here:

<SfTextBox @ref=TextObj ID="textbox" Placeholder='First Name' @onfocus='@(e => KeyPressed(e, TextObj.ID))'>



@code {

    SfTextBox TextObj;

    public void KeyPressed(Microsoft.AspNetCore.Components.Web.FocusEventArgs args, string ID)

If you want to pass a parameter to the click event handler you need to make use of the arrow function or bind the function.
