Hi!

How do I get the first visible item in RadListView?
And how do I set it up?
Like the TopItem property of a WinForms ListView.

Hey folks!

I need to display a lengthy list of "cards" or perhaps "cells" horizontally.  There will be NO vertical scrolling.  It would be nice if I can scroll horizontally by click+dragging.

Each "card/" will have an Image (thumbnail on the left or top) and some text (on the right or bottom)

I've used ListView for multiple UI requirements but I cannot figure out how to get the items to display "all horizontally" - the control wants to fill with Items until the last item that would normally have gone beyond the right side of the control and instead, it wraps to the next row below.  This "wrapping" is what I need to prevent.

I've never used CardView but maybe this is the way I should go?

All thoughts/comments would be appreciated!

Kind regards,

Hi,

When I add a RadListView to the RadForm, the entire list view has a border. However, as soon as I add rows, the right border below the rows disappears.

What setting can I use to ensure that a full right border is always visible?

Kind regards,

Guido

Hello everyone :)

I've got a new project that includes a RadListView that I have placed on a WinForm with ViewType = IconsView

I'd like to display a thumbnail along with some HTML text - but I'm struggling getting the data I need from the object being formatted.

Here's my VisualItemFormatting method:

myViewElement.Items(0).Tag holds a class that contains the text I'd like to display along with the correct icon size (these are documents of various sizes so I'd like the icons to have the same width/height ratio.

myViewElement.Items(0).Tag is clearly WRONG...it's there and not Nothing but it's the 0 index of all Items in the RadListView and it's in my code as a place holder so I could build the rest of the UI class.

Does anyone know how I can get the index of the ListViewItem that's being "formatted" by VisualItemFormatting?  Of not the index from the RadListView's Item collection, maybe the actual ListViewItem object itself?

Any help would be appreciated.

Thank

Description:

I recently upgraded my .NET Framework project to .NET Core 8. However, I'm now encountering an issue where the RadListView component is not recognized. I've tried adding the necessary NuGet packages, but the error persists.

The specific error message I'm receiving is:

CS0234: The type or namespace name 'RadListView' does not exist in the namespace 'Telerik WinControls.UI' (are you missing a reference?)

I've attached a screenshot of the error message for your reference.

I'm using the Telerik RadControls for WinForms library, and I've made sure to install the latest version of the NuGet package (Telerik.WinControls.dll). I've also tried adding the following using directives:

using Telerik.WinControls.UI;
using Telerik.WinControls;

But the error persists.

I've searched for similar issues online, but I haven't been able to find a solution that works for me. I'm hoping someone here can help me troubleshoot this problem.

Additional details:

• I'm using Visual Studio 2022.
• I'm targeting .NET Core 8.
• I've tried cleaning and rebuilding the project.

Any help would be greatly appreciated.

Here are some additional things you can include in your forum post:

• Any relevant code snippets
• The exact versions of the Telerik RadControls for WinForms library and NuGet package that you're using
• The steps you took to upgrade your project to .NET Core 8

I hope this helps!

I need to quickly develop an 'updater' application that allows updating one or more software. I would like a look similar to the Adobe updater. What should I choose as a component? A grid? A ListView? Is it possible to have a column in the grid that changes its appearance: switches from a button to a progress bar?

I can't consistently have the SelectedItemChanged event called when clicking an item with a Listview in IconsView.  If a click is made in empty space, the event is triggered.  

What am I missing?

Attached is a sample app.

 Thanks,

Hello, 

I'm currently building a material library tool using Telerik's RadListView. I pretty much got it near exactly what I'm after. However, I'm having some trouble with the last feature, and I'm hoping someone can provide some insight.

What I'd like to do is add an icon to the top left-hand corner of each item that will represent their category.

So far, using the following code and a bit of trickery with HTML markup, my ListView Items currently look like this.

(Written in C++)

    //Create a new ListView Item
    Item = gcnew ListViewDataItem();
    
    //Generate HTML Label
    String^ Label = "<html><strong>" + Name + "</strong><br><span style=\"color:f5f5f5\"><i>" + Latin + "</i></span></html>";
    Item->Text = Label;
    Item->TextAlignment = ContentAlignment::MiddleCenter;
    Item->TextImageRelation = Windows::Forms::TextImageRelation::ImageAboveText;

    //Load the Thumbnail
    String^ thumbnailPath = Path + "\\" + ThumbPath;
    Item->Image = Image::FromFile(thumbnailPath);
    Item->ImageAlignment = ContentAlignment::TopCenter;
   

However, what I'd like to achieve is this:

I was hoping there was a Background Image property for ListViewDataItem. However, that doesn't seem to be the case. Is there a clever trick to achieve this? Or is my only option to create a Custom ListViewDataItem as described here? https://docs.telerik.com/devtools/winforms/controls/listview/custom-items

Thanks!
