MultiColumn Listbox

[Arash]

Hi,

 

Do you have any plan to implement MultiColumnListBox? It seems that you have already done that inside MultiColumnComboBox when it opens up.

Hello Arash,

A feature request for such a multi-column select component is logged in our public feedback portal: Add the MultiColumnMultiSelect component. I've voted on your behalf to raise its priority. Also, you can subscribe to it to get email notifications for any status changes.

In the meantime, a possible alternative to achieve a similar layout is to use the existing ListBox component with an ItemTempate to display multiple columns within each item. Here's a basic example:

<TelerikListBox Data="@items" Width="400px" Height="300px">
    <ItemTemplate>
        <div style="display: flex;">
            <div style="width: 200px;">@((context as YourDataType).Column1)</div>
            <div style="width: 200px;">@((context as YourDataType).Column2)</div>
        </div>
    </ItemTemplate>
</TelerikListBox>

@code {
    List<YourDataType> items = new List<YourDataType>
    {
        new YourDataType { Column1 = "Item 1", Column2 = "Description 1" },
        new YourDataType { Column1 = "Item 2", Column2 = "Description 2" }
        // Add more items as needed
    };

    public class YourDataType
    {
        public string Column1 { get; set; }
        public string Column2 { get; set; }
    }

I hope you find well the provided information.

MultiColumnComboBox already has most of the functionality baked in, so it feels like a natural step to expose that as a standalone MultiColumnListBox component.
