PageResult always returns null in IAsyncPageFilter - OnPageHandlerExecutionAsync in Asp.Net Core 2.0 Razor...
I'm using a ModelValidationFilter to handle model validation errors for all my post or put requests. I'm using IAsyncPageFilter and registering as a global filter. In the OnPageHandlerExecutionAsync method, I'm able to handle the validation errors for ajax requests and send back a json response. But for non ajax request,
I'm getting always null for var result = (PageResult)context.Result;
Please could you assist me on this?
I'm implementing this so that I don't need to write model validation in all post or put handlers in any razor page in my application.
Here is my implementation:
if (context.HttpContext.Request.Method.Equals("POST") || context.HttpContext.Request.Method.Equals("PUT"))
{
if (!context.ModelState.IsValid)
{
if (context.HttpContext.Request.IsAjaxRequest())
{
var errorModel = context.ModelState.Keys.Where(x => context.ModelState[x].Errors.Count > 0)
.Select(x => new
{
key = x,
errors = context.ModelState[x].Errors.Select(y => y.ErrorMessage).ToArray()
});
context.Result = new JsonResult(new AjaxResultHelper<IEnumerable<object>>
{
Response = errorModel,
Message = "_InvalidData_"
});
}
else
{
var result = (PageResult)context.Result;
context.Result = new PageResult
{
ViewData = result.ViewData,
ContentType = result.ContentType,
StatusCode = 400,
};
}
}
}
else
{
await next.Invoke();
}
