"Object not set to an instance of an object" following 2.62.3 upgrade?

Last week I completed a stage of development, published the project for client review then closed Radzen down. This triggered the latest update to 2.62.3. Following this error messages are generated against custom row templates (on multiple pages) whenever I try to expand the template row:

Error: System.NullReferenceException: Object reference not set to an instance of an object.
at Radzen.PagedDataBoundComponent1.CalculatePager() at Radzen.Blazor.RadzenGrid1.OnParametersSetAsync()
at Microsoft.AspNetCore.Components.ComponentBase.CallOnParametersSetAsync()
at Radzen.RadzenComponent.SetParametersAsync(ParameterView parameters)
at Radzen.PagedDataBoundComponent1.SetParametersAsync(ParameterView parameters) at Radzen.Blazor.RadzenGrid1.SetParametersAsync(ParameterView parameters)

The published project (on Azure; pre-upgrade) runs fine with no errors.

If I create a new grid with row template, this works fine.

In the RADZEN IDE I see the following on each affected page where the master grid is defined:


Project builds and runs fine, with issue restricted to the row expand button:

This is the same project published on Azure working without issue:

Anyone have ideas on this one? I don't want to have to re-build each grid once again, they have many useful features that took some time to refine!

Many thanks

Hi @Graeme_Atkinson,

We believe that we’ve fixed this issue already and later today we will publish update of Radzen.Blazor.

Many thanks - latest update has now resolved this issue.
