I'm looking for what you have in WPF as we migrate ourselves over to Blazor - https://www.telerik.com/products/wpf/conversational-ui.aspx

ADMIN EDIT

For the time being, you can consider using the Kendo Chat widget as described in this sample project.

I have a requirement to design our own custom add/edit template form for scheduler control.

I looked at  custom edit form example and found very helpful, However this example does not demonstrate how to use RecurrenceEditor and use them in custom template.

When a user invokes a Search tool, their intention is to directly write a text to search, therefore the edit for the search text should be focused immediately. In the current implementation, users have to manually focus the edit all the time, which is really inconvenient.

One can generally loop through a collection of items to create several TabStrip instances as shown in the Tabs Collection article.

However, when I am dynamically adding or removing tabs I am hitting a variety of problems targeting:

• The active tab is not correctly set;
• The focus is not always set on the active tab;
• Upon adding/removing a tab, all tabs are re-created and thus their content cannot be persisted;

Please add support for dynamic tabs.

The feature request is to be able to customize the GridCsvExportOptions and GridExcelExportOptions from the API methods -

• ExportToExcelAsync
• ExportToCsvAsync
• SaveAsExcelFileAsync
• SaveAsCsvFileAsync

It will be useful to be able to customize the columns and data to be exported.

Telerik edit:

A possible workaround is to click the built-in Grid export buttons with JavaScript. With this approach, you will be able to use the built-in export options and events. Here is a REPL example.

Support the recurrence rule to create multiple appointments per time slot. Examples of such rules are:

FREQ=DAILY;BYDAY=MO,TU,WE,TH,FR,SA,SU;BYHOUR=08,09,10,11,12,13,14,15,16;BYMINUTE=50

It would be nice to be able to configure a show/hide animation for windows.

ADMIN EDIT: This might include a form of a Shown event so that you could know when the content is rendered and available to, for example, focus a button or input. For more details see here

Like https://docs.telerik.com/blazor-ui/components/combobox/custom-value and https://www.telerik.com/kendo-angular-ui/components/dropdowns/multiselect/custom-values/ so the user can input tags on their own without them being in the app data source.

ADMIN EDIT

The following sample may be useful in implementing this in the meantime: https://github.com/telerik/blazor-ui/tree/master/multiselect/add-new-item

I am working on a form where experienced agents need to input data quickly. Often enough they know the codes and so they can type them in the combo box, but they shouldn't have to look for the mouse to select the item, the combo box should select it when the user presses Tab to move to the next field.

This should happen only when the user has filtered the combo box so they see some items (and so the dropdown is open) - I want them to be able to select only items from the available options, AllowCustom does not work for me.

Here is one workaround you can consider:

https://blazorrepl.telerik.com/QoOAPyEZ233YP2AX19

@inject IJSRuntime js

@* Move this script to a separate JS file *@
<script suppress-error="BL9992">
    function getHighligtedComboItem() {
        // Get the currently focused item in this particular ComboBox.
        var focusedItem = document.querySelector(".select-on-tab .k-list-item.k-focus");
        if (focusedItem) {
            return focusedItem.innerText;
        }
    }
</script>

<p>FirstFilteredItem: @FirstFilteredItem</p>

<p>Selected value: @ComboBoxValue</p>

            await Task.Delay(400);
        }

        {
            // Wait, depending on the typical filtering time.
            await Task.Delay(300);
        }

        // The code that will find the item text depends on the exact scenario and potential use of ItemTemplate.
        FirstFilteredItem = await js.InvokeAsync<string>("getHighligtedComboItem");
    }

    {

            var matchingItem = ComboBoxData.Where(x => x.Text.ToLowerInvariant().Contains(FirstFilteredItem.Trim().ToLowerInvariant())).FirstOrDefault();
            if (matchingItem != null)

I want to filter a Grid by DateTimeOffset? field

===ADMIN EDIT===

There are two possible options:

1. Use a DTO in which you have a DateTime field converted as desired by your app from the DateTimeOffset. Filtering, sorting, editing, and grouping on DateTime values are supported out-of-the-box.

REPL example that demonstrates this approach. 

2. Use the Grid Filter Template. As a filter editor, you can use the DateTimePicker component, which supports the DateTimeOffset type. 

REPL example that demonstrates this approach. 

I have a scenario in which we have user definable columns for a grid, including hundreds if not thousands that need to be ported from the old version of our product. This means these column keys would be strings that may contain spaces or even special characters - and as such cannot be a valid C# property name (which means using an ExpandoObject approach will not work)

It would be really beneficial if the TelerikGrid component could be given Data of an IEnumerable<Dictionary<string, object>> where the Field property of GridColumn (or a new property) would line up with a key in that dictionary rather than a field name for the component to then use reflection with.

A customer with multiple modules of our product installed may very well have columns with similar names, i.e "Some Key", "SomeKey", "Some_Key", "Some & Key" - so simply replacing spaces or special characters may not always still give unique keys.

Please provide item templates for the file list, similar to:
