如何将自定义radzendropdown项目设置为页面加载？

Question

我已经在下面显示的代码中填充了Radzendropdown，

<RadzenDropDown @bind-Value="SomethingValueSelected" TValue="int" AllowFiltering="false" AllowClear="false" SelectedItem="0" SelectedItemsText="Test-1"
                        Data=@SomethingList TextProperty="Name" ValueProperty="Value"/>

这是带有填充项目的列表：

List<SomethingDTO> SomethingList= new List<SomethingDTO>(){ new SomethingDTO{ Name = "Test-1", Value = -1 },
                                                                                new SomethingDTO{ Name = "Test0", Value = 0 },
                                                                                new SomethingDTO{ Name = "Test1", Value = 1 },
                                                                                new SomethingDTO{ Name = "Test2", Value  = 2 },
                                                                                new SomethingDTO{ Name = "Test5", Value = 5 }};
int SomethingValueSelected;

这是我在页面加载时得到的：

好吧，这似乎很简单 -
只需将被束缚的元素的值设置为您喜欢的价值，就我而言是

int SomethingValueSelected = -1;
