Telerik.Blazor.Components.TelerikWindow does not have a property matching the name 'Centered'

[Sherzod]

When building the application in Release configuration and navigating to the page containing the ReportViewer component, the following error is thrown:

“Telerik.Blazor.Components.TelerikWindow does not have a property matching the name ‘Centered’.”
at Microsoft.AspNetCore.Components.Reflection.ComponentProperties.ThrowForUnknownIncomingParameterName(Type targetType, String parameterName) at Microsoft.AspNetCore.Components.Reflection.ComponentProperties.SetProperties(ParameterView& parameters, Object target) at Microsoft.AspNetCore.Components.ParameterView.SetParameterProperties(Object target) at Microsoft.AspNetCore.Components.ComponentBase.SetParametersAsync(ParameterView parameters) at Telerik.Blazor.Components.TelerikWindow.SetParametersAsync(ParameterView parameters) at Microsoft.AspNetCore.Components.Rendering.ComponentState.SupplyCombinedParameters(ParameterView directAndCascadingParameters)

This problem does not occur in Debug mode and was not present in earlier builds. The affected page uses both the ReportViewer component and the SendEmailDialogSettings. For reference, the project is targeting .NET 8.0 and depends on:

• Telerik.UI.for.Blazor (v9.1.0)
• Telerik.ReportViewer.BlazorNative (v19.1.25.521)

The page:
    <TelerikTabStrip TabPosition="TabPosition.Top" TabAlignment="TabStripTabAlignment.Start">

        <TabStripTab Title="Sink">
            <ReportViewer ServiceType="@ReportViewerServiceType.REST"
            ServiceUrl="@ReportServerUrl"
                @bind-ReportSource="@ReportSourceOrganisations"

                @bind-DocumentMapVisible="@DocumentMapVisible"
                @bind-Scale="@Scale"

                    To="@Emails"
                    Cc="@CarbonCopyEmail"
                    Subject="@Subject"
                    Format="XLSX"
                    Body="<br/> <br/> Best regards, </br>">
                    </SendEmailDialogSettings>
                </ReportViewerSettings>
            </ReportViewer>
        </TabStripTab>
    </TelerikTabStrip>

Hi Sherzod,

The error occurs because the Centered parameter was removed from the TelerikWindow component starting with Telerik UI for Blazor v9.0.0.

Here are the breaking changes notes from that release: Breaking Changes Notes 9.0.0.

In short, the Centered parameter did not work after the initial Window display. Removing the parameter actually made the component setup and management simpler. Otherwise, the app should also reset Top and Left explicitly when setting Centered="true" programmatically.

To center the Window, simply set the Top and Left parameter values to an empty string at any time.

Thank you for your response. 
It appears that the error originates from the email-dispatch window, to which I have no direct access and cannot alter its internal properties. 
As a result, I am uncertain how to apply the @bind-Left and @bind-Top attributes to this component.

Hello,

I am also experiencing the issue that has already been reported:

When building the application in Release configuration and navigating to the page containing the ReportViewer component, the following error is thrown:

“Telerik.Blazor.Components.TelerikWindow does not have a property matching the name ‘Centered’.” at Microsoft.AspNetCore.Components.Reflection.ComponentProperties.ThrowForUnknownIncomingParameterName(Type targetType, String parameterName) at Microsoft.AspNetCore.Components.Reflection.ComponentProperties.SetProperties(ParameterView& parameters, Object target) at Microsoft.AspNetCore.Components.ParameterView.SetParameterProperties(Object target) at Microsoft.AspNetCore.Components.ComponentBase.SetParametersAsync(ParameterView parameters) at Telerik.Blazor.Components.TelerikWindow.SetParametersAsync(ParameterView parameters) at Microsoft.AspNetCore.Components.Rendering.ComponentState.SupplyCombinedParameters(ParameterView directAndCascadingParameters)

My project is using:

• Telerik.UI.for.Blazor (v9.1.0)

• Telerik.ReportViewer.BlazorNative (v19.1.25.716)

I am attaching a zip file where the error can be reproduced by simply running the project.

I have also deleted the bin and obj folders and cleared NuGet caches, but I haven't been able to resolve the problem. Is there any guide or further assistance you can provide to help me with this?

After removing the bin and obj folders and rebuilding the solution, the issue was resolved.
