Since updating to 4.0.0 I am getting error when creating a new ExcelExportableColumn now.

var isBugColumn = new Telerik.Blazor.Common.Export.Excel.ExcelExportableColumn() { Field = "IsBug", Title = "Is Bug" };

Getting error that "ExcelExportableColumn is inaccessible due to its protection level"

Is it possible to have mutiple resources of the same type on the same appointment?  For example, in our system we could have a Patient Appointment with multiple physical therapists.  In our system the resource ids stored in an appointment is a list not a single value as I have seen your examples.

Thanks!

Hello,

I am trying to set up a GroupFooterTemplate and to calculate a value to put in the footer I need to know the value of the grouped attribute. In this case I am grouping on a column named "Category" and I call a function that needs to know the value of the category column in the group above the footer. If that's not clear here is a screenshot to help illustrate the value I'm trying to find when generating the group footer.

So I'm hoping to be able to pull that category value, "Biological" or "Kiln", when generating the group footer which I do by using the code here.

<GridColumn Field="@lengthColumnName" FieldType="@typeof(decimal)" Title="@myName" Width="180px">
                      <GroupFooterTemplate Context="unitFooterContext">
                              Total: %@calculateSubtotal(lengthColumnName, "Biological").ToString()
                      </GroupFooterTemplate>
</GridColumn>

On the Blazor Upload demo page it shows the control with a "drag and drop" option. I haven't been able to find information on the site on how to implement that. I have found a few places where it makes it sound as if that is not yet possible. Can you direct me to a location where it has further information on that feature? Thanks

Before upgrading to 4.0, I used to define a GridCommandButton this way (with FontAwesome custom icons) :

<GridCommandButton IconClass="fal fa-sync-alt fa-lg" OnClick="Refresh">@Resources.Refresh</GridCommandButton>

But now with 4.0, IconClass parameter has been removed. Documention says to use Icon parameter, that only accept a FontIcon or SvgIcon object value.

But how do a use those to display my custom icon in above code?

Working on some CSS stuff in Telerik for Blazor and see some CSS rules defined like this: 

.k-this-class {

    color: green;

}

.\!k-this-class {

   color: blue;

}

What does the .\! do in CSS?

Thanks. 

We color code each day of the week based on a service call.  Is there a way to know when the month is changing so that we can fire our service call event and populated disabled dates and colors for the calendar cells?

One idea I had was when rendering the cells, check to see if the first is being rendered then fire the service call event.  Doesn't seem like the best option as that would cause the rendering to pause while the call was being executed.
