Currently, it is possible to expand or collapse PanelBar items programmatically.

There should be a way to prevent a specific PanelBar item from collapsing or expanding.

Please expose cancellable OnExpand and OnCollapse events similar to other components. This will give developers the ability to apply custom interaction based on their scenario.

Zooming levels would be great

GanttCommandButton Command="ZoomIn|ZoomOut|ZoomToFit"...>

The current Views (Day/Week/Month/Year) are nice, but custom zooming is needed sometimes.

When selecting an image, I expect drag handles to show me that an image selection has occurred and that let me resize the image.

I noticed Telerik Blazor grid is rendered into two tables. One for the headers and one for the contents.

My assumption is that Allyable Scan expects to find a th element inside the second table and it did not find any. Is my assumption correct? 

Element source:

<table role="grid" style="width: ;">

If there are many subfolders below a folder the list becomes too long for the TreeView window and gets cut off at the bottom. Apparently, there are some height and overflow settings missing. After some digging around in the rendered HTML and copying some CSS selectors (using F12 on Edge) I got it working with this in my CSS file:

.k-filemanager-content-container > div > div.k-pane.k-filemanager-navigation.k-pane-static > div > div > ul {
    height: 100%;
    overflow: auto;
}
.k-filemanager-content-container > div > div.k-pane.k-filemanager-navigation.k-pane-static > div > div {
    height: 100%;
}

----------ADMIN EDIT----------

In the meantime, here is a possible workaround:

<style>
 .k-treeview-lines {
        height: 100%;
 overflow: auto;
    }

    .k-filemanager-treeview {
        height: 100%;
 }
</style>

Hi,

  I had to figure this out myself for the ComboBoxSettings because there is no documentation for this. 

  The MinWidth works from the Combobox width or greater extending the size of the popup and

   MaxWidth only creates a popup width of the Combobox only. 

Please document this feature and how to use it.  And, is this intentional because it wasn't intuitive for me to figure out.

I created a REPL for you to test this out for yourself.

Hello Team,

I am using "FilterMode="GridFilterMode.FilterRow". For int values there is a "numeric chooser" in the column header and the filter option "contains" is not available.

This is the correct behaviour. But when I bind the column to a ulong, ushort, ... value theses seems to be considered as string. There is no "numeric chooser"  and the filter "contains" is available, which resullts in further problems with the OData endpoint.

If you drag an occurrence to a different time slot, a new appointment is created and the series is accordingly updated. However, if you are editing an occurrence via the edit form to change its start and end, a new appointment is correctly created but the initial occurrence remains not updated in the series.

Can be reproduced in the Appointment Editing demo.

If the Grid has no data, selecting null PageSize throws:

Error: System.ArgumentException: Page Size cannot be less than one (Parameter 'PageSize')

ADMIN EDIT

A possible workaround for the time being will be to use some conditional CSS to disable the PageSize dropdown while there is no data in the Grid: https://blazorrepl.telerik.com/QcOpkTlb38EDFboT34.

I want to customize the appearance of the header of a certain column, and a bit of CSS backgrounds could help, but I can't do this with the HeaderTemplate alone, nor with content in it because of the padding the cells have.

So, I would like the ability to set the CSS class of the header cell of the column.

The idea of the feature is to be able to customize the list of FilterOperators displayed in the list of the FilterRow and FilterMenu.

FilterRow UI element

FilterMenu UI element

By default, all nested tasks are displayed expanded.
The state of the root task is always the most important, so it makes more sense to display tasks minimized by default.
The user can always expand the required task for details.
The solution is to support the "IsExpanded" property for the task model.
When a property changes, the task changes its state.
For the component, also add the "ExpandAll" and "CollapseAll" methods that affect all tasks in the list.

In hierarchical Grid with InCell edit the DateTime cells of the child Grid cannot be edited through the calendar popup. Trying to open the DatePicker or DateTimePicker popup of the child Grid automatically closes the edited cell.
