RadzenDropDownDataGrid Filtering with Dynamic Data

Hi,
I am using RadzenDropDownDataGrid for dynamic data. Before moving into my real scenario I tested this with dummy data. Here is my dummy data list.

data = new List<IDictionary<string, object>>()
{
new Dictionary<string, object>()
{
{ "FirstName", "Johan" },
{ "LastName", "Wiberg" },
},
new Dictionary<string, object>()
{
{ "FirstName", "Sandra" },
{ "LastName", "Perera" },
}
}

This is the column list.

columns = new Dictionary<string, Type>()
{
{ "FirstName", typeof(string) },
{ "LastName", typeof(string) },
}

Here is my implementation.

public string valueProperty { get; set; } = "LastName";
public string textProperty { get; set; } = "FirstName";

This implementation gives an error like below.

Could you please tell me the issue with this implementation or could you please give an example for RadzenDropDownDataGrid with dynamic data?

Yeah, I have checked that but didn't find a solution from there.
