Blazor how to pass arguments to onclick function?

Question

I\'d want to make button onclick function that takes some input.

Check

@functions
{
    pu         


        

Answer 1

At Sign on onclick specifies it's a C# function:

@onclick = "@(() => test(i, 5*i))"

Answer 2

<input type="button" @onclick="@(() => functionname(paramvalue))" class="....." value="DoSomething" />

Answer 3

Try it with a lambda. You're binding the onclick to the result of the function rather than the function itself.

@for (int i = 0; i < 10; i++)
{
    var buttonNumber = i;
    <button @onclick="@(e => test(buttonNumber, 5 * buttonNumber))">Check</button>
}

Answer 4

I try this and worked

@onclick="(() => FunctionName(argument))

like

@onclick="(() => GetDetail(item.UserId))

Got idea from https://github.com/aspnet/AspNetCore/issues/15956 .
