Describe the bug
之前是在NET6.0环境中，可以正常显示数据，升级到NET8.0后，无法正常显示数据。
HubConnection的On方法中调用Table的QueryAsync()方法的代码如下
hubConnection.On<string, List<DeviceTagInfo>>("ReceiveDeviceVariablesNotify", async (deviceName, deviceTagInfos) =>
{
if (deviceName == DeviceName)
{
var encodedMsg = $"Device KeyPairs: {deviceTagInfos}";
DeviceTagInfos = deviceTagInfos;
await TableElement.QueryAsync();
}
});Table的OnQueryAsync事件的实现如下
private async Task<QueryData<DeviceTagInfo>> OnQueryAsync(QueryPageOptions options)
{
List<DeviceTagInfo> items = DeviceTagInfos;
// 设置记录总数
var total = items.Count();
// 内存分页
items = items.Skip((options.PageIndex - 1) * options.PageItems).Take(options.PageItems).ToList();
return new QueryData<DeviceTagInfo>() { Items = items, TotalCount = total };
}执行完OnQueryAsync所有方法后，VS自动进入以下部分进行报错。
通过测试，把BootstrapBlazor的Table组件中的QueryAsync方法中 ，StateHasChanged 换成异步调用就可以了，await InvokeAsync(StateHasChanged);
private async Task QueryAsync(bool shouldRender, int? pageIndex = null)
{
if (ScrollMode == ScrollMode.Virtual && VirtualizeElement != null)
{
await VirtualizeElement.RefreshDataAsync();
}
else
{
await InternalToggleLoading(true);
if (pageIndex.HasValue)
{
PageIndex = pageIndex.Value;
}
await QueryData();
await InternalToggleLoading(false);
}
if (shouldRender)
{
//StateHasChanged
//此部分换成异步调用
await InvokeAsync(StateHasChanged);
}
}Expected Behavior
