My project is using the client/webassembly template and I get this error when I sort on the Grid.  I am using CSLA business objects to bind to the grid by the way.  It should just work since it derives from IEnumerable<T>.  The TelerikBlazorApp project sample uses a plain List<WeaterForecast> so I wonder why it doesn't work with the CSLA BusinessList.

Thanks.

hello i have a couple of questions about blazor grid 

 

1) i added a grid column called actions it contains some buttons to navigate but when i add  Reorderable="true" to TelerikGrid im able to change position of this column which i dont want to so i added Reorderable="false" to my action column and it worked i cant change it's position anymore but i can drag my other columns and put it before my action column so it gets affected by the reorderable column and its position gets changed 
but i dont want to

2) i also used Sortable="true" and  FilterMode="@GridFilterMode.FilterMenu" in my TelerikGrid tag but it doesnt get filtered nor sorted i see the red arrow for sort but it doesnt sort and also ui for filter is completely ok but it doesnt filter either aldo the Data im passing to grid is List<SomeDto>

hello it seems there is a problem with OnRead in TelerikGrid

when i try to use OnRead for virtual mode it works fine first time page renders it works and also on scroll it works too
but when i navigate to another page and try to change the Data and then navigate back to the page it seems it kept the last state and i see the previous Data 
untill i use filter , sort , i scroll 

hello i wanted to know if there is a way to set a column sortable to false

 

and also how to get context in GridCommandColumn

hello,

TelerikButton is not working correct with EditForm 
when i use

       <input type="submit" class="btn btn-primary" value="Save" />
instead of 
<TelerikButton ButtonType="@ButtonType.Submit">Save</TelerikButton>
im able to submit the form with hitting enter
i want this feature with TelerikButton 

hello, 
i wanted to know if returned value of Timepicker could be timespan or not ?

How do I install the Demo version on MacOS (Mojave)?

When I try to download, I only have the option of an exe or an msi - neither of which open on the Mac.

When holding down a key in the Telerik TextBox the text seems to stutter like the TextBox is trying to catch up to the user inputs.  This happens with the backspace key, and even happens when there are no events tied to the TextBox.  We don't see this behavior when using a <input type="text" /> field.  It appears to be happening in your demo too.  Is this a known issue?
