blazor select onchange code example

Example: blazorstrap dropdown onchange

//Your answer should be in the cshtml:

<select class="form-control"  @onchange="@OnSelect" style="width:150px">
    @foreach (var template in templates)
    {
        <option value=@template>@template</option>
    }
</select>

<h5>Selected Country is: @selectedString</h5>

//Then your @functions or @code if Blazor should look like:

@code {
    List<string> templates = new List<string>() { "America", "China", "India", "Russia", "England" };
    string selectedString = "America";

    void OnSelect (ChangeEventArgs e)
    {
            selectedString = e.Value.ToString();
            Console.WriteLine("The selected country is : " + selectedString);
    }
}
