Seems like this should be simple, but it's eluding me. Basically, I have a treeview and button. If teh user has selected a node and then clicks on my button,
how do I tell which node is active?
Thanks … Ed

I am using TabStrip to display steps of a process. When any of the steps is completed, I would like to mark that tab. Ideally, I would like to put a checkbox in the tab title. Alternatively, placing an icon into the title would suffice. As a last option, if any of the previous ones are not possible, I would like to control the style of individual tabs with CSS. Is any of this possible?

Looking at your components for the first time and downloaded the 30 day trial today. I note in Visual Studio 2019 that you set <LangVersion> to 7.3 for each of the samples and the VS templates I've installed.
Is this a requirement to stay compatible with your package?
The big pull for us with C# 8 is nullable reference types. I suppose I can just turn it on and wait for Telerik components to be incompatible.

It would be nice to have templating abilities for an appointment on the calendar. I would like to add more than just title and description. For instance, to have aircraft identifier, arrival and departure airport codes and depart times.

For this TreeView definition, I want the button background to be black with white font when the TreeItem.Selected property is true. Then, I want the node to go back to a clear background with black font when when that property is false. How do I do this?

I would like to display a message where rows would be displayed in grid, when there are no records returned from the data source. Basically, a message with graphics and hyperlink that direct the user to a page to enter a new record. Is there any feature of the grid that would support this thy of workflow? Row Template maybe?

The pager for my Blazor UI Grid has been working just fine for over a month but now it is missing the button box around the 1 when I view the first page. The second page has a box around it like a typical button. When I click on the 2 button to display page 2, the 2 button no longer has a box around it but the 1 button does. So it seems to be a css issue with the currently selected page.
<TelerikGrid Data="@GridData"
TotalCount="@Total"
Sortable="true"
Pageable="true"
PageSize="@PageSize"
OnRead="@OnReadHandler">
<GridToolBar>
<TelerikButton OnClick="@(() => SelectAccount(null))" Icon="add">Add Account</TelerikButton>
</GridToolBar>
<GridColumns>
<GridCommandColumn Width="200px" Resizable="false">
<GridCommandButton OnClick="@((args)=> SelectAccount(args.Item as AccountModel))" Icon="edit">Edit</GridCommandButton>
<GridCommandButton OnClick="@((args)=> ShowDeleteConfirmationDialog(args.Item as AccountModel))" Icon="delete">Delete</GridCommandButton>
</GridCommandColumn>
<GridColumn Field="@(nameof(Account.AccountName))" Title="Account Name" />
<GridColumn Field="@(nameof(Account.AccountType))" Title="Account Type" />
<GridColumn Field="@(nameof(Account.OwnerName))" Title="Account Owner" />
<GridColumn Field="@(nameof(Account.Status))" Title="Status" />
</GridColumns>
</TelerikGrid>
