NOTE: We do not look at .zip attachments for issue investigation.

Describe the bug
If i try a to filter a Property of a nested objekt, it dont work!

To Reproduce
Create a nested Item like

public record class EmployeeName
{
  public string? FamilyName { get; set;}
  public string? GivenName { get; set;}
}

public record class Employee5
{
  public int? Id{ get; set;}
  public EmployeeName? Name { get; set;}
  public string? Designation { get; set;}
  public DateOnlyß DOJ { get; set;}
  public bool IsActive { get; set;}
}

Create a grid like this:

<Grid TItem="Employee5"
      Class="table table-hover table-bordered table-striped"
      DataProvider="EmployeesDataProvider"
      AllowFiltering="true"
      Responsive="true">

    <GridColumns>
        <GridColumn TItem="Employee5" HeaderText="Id" PropertyName="Id">
            @context.Id
        </GridColumn>
        <GridColumn TItem="Employee5" HeaderText="Employee Name" PropertyName="Name.GivenName">
            @context.Name.GivenName 
        </GridColumn>
        <GridColumn TItem="Employee5" HeaderText="Designation" PropertyName="Designation">
            @context.Designation
        </GridColumn>
        <GridColumn TItem="Employee5" HeaderText="DOJ" PropertyName="DOJ">
            @context.DOJ
        </GridColumn>
        <GridColumn TItem="Employee5" HeaderText="Active" PropertyName="IsActive">
            @context.IsActive
        </GridColumn>
    </GridColumns>

</Grid>

Expected behavior
It should be possible to work, like on other not nested properties.

Possible Fix
In ExpressionExtensions.cs:

Change all of this line:

var propertyExp = Expression.Property(parameterExpression, filterItem.PropertyName);

=>

Expression propertyExp = parameterExpression;
foreach (var propertyName in filterItem.PropertyName.Split('.'))
{
 propertyExp = Expression.Property(propertyExp, propertyName);
}

In TypeExtensions.cs:

Add this methode:

  public static Type GetNestedPropertyType(Type type, string propertyPath)
  {
    string[] properties = propertyPath.Split('.');
    foreach (var property in properties)
    {
      PropertyInfo propInfo = type.GetProperty(property);
      if (propInfo == null)
      {
        return null;
      }
      type = propInfo.PropertyType;
    }
    return type;
  }

Change this line:

var propertyType = type.GetProperty(propertyName)?.PropertyType;

=>

var propertyType = GetNestedPropertyType(type, propertyName);
