I am working on having a button setup that opens a blazored modal that allows a user to enter in the hours and minutes worked on a request, as well as adding comments. I started using the Blazored.Modal nuget package the [CascadingParameter] is used for closing or submitting the data in the modal. When looking through with a break point on I found that the
[CascadingParameter] BlazoredModalInstance BlazoredModal { get; set; }
comes back NULL when I try to pass data in form the parent object. I have attached my code for my issue below. Thanks for your help and responses in advanced.
