Blazor onclick event not triggered

this will help I think your call to the onclick event is wrong, they changed the way you reference functions from
code :
<button class="btn btn-primary" onclick="@IncrementCount();">Click me</button>
<button class="btn btn-primary" @onclick="IncrementCount();">Click me</button>

onclick event not triggered when onchange triggered right before

this will help You need to recheck your assumptions. In your example, alert() interrupts the program flow, breaking handling of onclick. This code (jsfiddle here) demonstrates that onchange does not interfere with onclick by default:
code :
<textarea onchange="processText();" name="mytext"></textarea>
<button onclick="processButton();">Hello</button>
<div id="clicked"></div>
<div id="changed"></div>
<script language="Javascript">
  function processText()
  {
    document.getElementById('changed').innerHTML = "onchange fired";;
  }

  function processButton()
  {
    document.getElementById('clicked').innerHTML = "onclick fired";
  }
</script>​

Blazor onclick event passing in counter from loop

I wish this help you Because i is a variable and the for loop is always finished when you click, it is 7 on that moment
You need to do something like:
code :
@for (int i = 0; i < vm.TotalPages; i++)
{
    var tempint = i;
    <button id="pg-button-@i" class="btn btn-primary btn-sm" type="button" onclick="@(() => GetTablePage(tempint))">@i</button>
}

In Blazor client app (razor component), does every event triggered refresh the UI?

I wish this help you Only DOM elements that have changes get updated, not the entire UI. Blazor uses what they call a Render Tree to keep track of the elements that have changed and need to be updated. When an event fires, it regenerates the Render Tree and compares it to the old one to find changes, and then only updates the changed items in the render tree in the DOM.

Blazor: How to pass a event to a onClick function, in a generic component

will be helpful for those in need I am working on a table component for a website I am making. I want to be able to Create, Update, Add, and Delete entries from the table, all on one page. I will also be using this component all over the website, and with many kinds of classes as the input. I went to here to learn how to do that. I also figured it would be smart to have an internal component that is each row in the table. Here is my code so far: , This is working:
EditableClass.razor
code :
@using WbotV2.Data
@using System
@using System.Collections
@using System.Reflection
@typeparam TItem

<tr>
    @foreach (var datum in Data)
    {
        <td>@datum</td>
    }
    <td><button class="btn btn-success">Edit</button></td>
    <td>@ChildContent</td>
</tr>


@code {
    [Parameter]
    public RenderFragment ChildContent { get; set; }
    [Parameter]
    public EventCallback<TItem> Delete { get; set; }

    [Parameter]
    public TItem Item { get; set; }

    public List<string> Data;
    public bool Editable = false;
    protected override void OnInitialized()
    {
        Data = GetData(Item);
    }

    public static List<string> GetData(TItem instance)
    {
        List<string> ret = new List<string>();
        FieldInfo[] infos = typeof(TItem).GetFields(BindingFlags.NonPublic | BindingFlags.Instance
            | BindingFlags.Public);
        foreach (FieldInfo info in infos)
        {
            ret.Add(info.GetValue(instance).ToString());
        }
        return ret;
    }
}
<EditableClass Item="@item"><button class="btn btn-danger" @onclick="@(() => Delete(item))">DeleteMe</button></EditableClass>


public void Delete(TItem itemToDelete)
    {
        DataInstance.Delete(itemToDelete);
      //  StateHasChanged();
       // Console.WriteLine("Here");
    }
