Having some issues with column widths. I want to statitcally set the width of all my columns except one and that one I want to expand or contract based on the size of my grid as my UWP form is resized, etc. With a previous grid I simply set the width of all the static columns to a value and then set the column of my dynamic column to star. Star is not accepted by the column width property here and the size modes dont seem to have a value that accommodates this.

 

What am I missing?

Hello,

Do you have an example to unzip a zip with multiple files ? 

I wish I could use ExtractToDirectory(string sourceArchiveFileName, string destinationDirectoryName), but it seems to not be available on Xamarin yet. 

Thanks.

I am getting the following error in Release mode in my Xamarin.Forms iOS project :

Can't resolve the reference 'System.Void Xamarin.Forms.Internals.ResourceLoader/ResourceLoadingQuery::set_Instance(System.Object)', referenced from the method 'System.Void Telerik.XamarinForms.Chart.TelerikThemeStyles::InitializeComponent()' in 'Xamarin.Forms.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null' 

 

I have tried various versions of Xamarin.Forms [from 3.6 to latest 4.4] to check the compatibility with this and recent Telerik packages but nothing seems to be working.

I have downloaded the ERP sample application and service.  I am running the service and changed the ApplicationURL to the service URL.

 

When I run the Application I am getting the following error: MvvmCross.Exceptions.MvxIoCResolveException: 'Failed to construct ErpService'

 

Any ideas what I am missing setting up?

Thanks -Tim

Hi,
recently I received crash with describe Unable to activate instance of type Telerik.XamarinForms.InputRenderer.Android.Button.ExtendedAndroidButton.

Is it known issue, or ho to find out where this exception was happen?
I got this crash first time after update XF and Telerik.UI.

XF:4.3.0.947036

Telerik:2019.3.1023.1

Sory, but code formatter doesn't work for me here.

When starting a cell edit, it is desired to have all the text selected, so the user can easily replace the current text without having to delete it.  From the docs, I do not see how to make this work.  Is it possible to get the current edit control that is attached to the cell during begin edit?

Hey,

I am trying to show a pdf from a stream via the pdfViewer,

<Grid>
         <Grid.RowDefinitions>
             <RowDefinition Height="Auto"/>
             <RowDefinition />
         </Grid.RowDefinitions>
         <telerikPdfViewer:RadPdfViewerToolbar PdfViewer="{Binding Source={x:Reference pdfViewer}}">
             <telerikPdfViewer:ZoomInToolbarItem />
             <telerikPdfViewer:ZoomOutToolbarItem />
             <telerikPdfViewer:ToggleLayoutModeToolbarItem />
         </telerikPdfViewer:RadPdfViewerToolbar>
         <telerikPdfViewer:RadPdfViewer x:Name="pdfViewer"
                                Grid.Row="1"
                                        Source="{Binding DocStream, Mode=TwoWay}"
                                PageSpacing="15"
                                MinZoomLevel="0.2"
                                MaxZoomLevel="5" />
     </Grid>

 

The view renders but there is no pdf, just a grey blank screen, there is no crash however the console output gives the following;

Im thinking SkiaSharp? but at a loss as to a solution?

Failed to bind EAGLDrawable: <CAEAGLLayer: 0x2866d0640> to GL_RENDERBUFFER 1
Failed to make complete multisample framebuffer object 8cd6
