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,

I have develop a custom tagger in order to format some specific words.

My problem is that the format is applying to this words even if they are used as strings (inside quotes).

I would like that the format only applies when the word is not in quotes.

In. Ex:

WORD -> Apply Format

"WORD" -> Do not apply format

This is my code:

using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using AutoMapper.Internal;
using Telerik.WinControls.UI;
using Telerik.WinForms.Controls.SyntaxEditor.Taggers;
using Telerik.WinForms.Controls.SyntaxEditor.UI;
using Telerik.WinForms.SyntaxEditor.Core.Tagging;

namespace Simulation.UX.Forms.Controls.Neptune
{
    public class CustomTagger : CSharpTagger
    {
        public static readonly ClassificationType CustomClassificationType = new("Custom");
        public static readonly Dictionary<string, ClassificationType> WordsToClassificationType = new();
        public static readonly TextFormatDefinition Format = new(new SolidBrush(Color.DarkGoldenrod));

        private readonly List<string> _words;

        public NeptuneTagger(RadSyntaxEditorElement editor, List<string> words) : base(editor)
        {
            _words = words;
        }

        protected override Dictionary<string, ClassificationType> GetWordsToClassificationTypes()
        {
            Dictionary<string, ClassificationType> baseTypes = base.GetWordsToClassificationTypes();

            _words?.ForAll(w =>
            {
                if (!baseTypes.ContainsKey(w))
                {
                    baseTypes.Add(w, CustomClassificationType);
                }
            });

            return baseTypes;
        }
    }
}

I am sure this is a setting somewhere, but I can't find it for my life.  In some cases, we have where Grid columns exceed the width of the visible grid.  When that happens, the grid data is centered in the visible area.  How can we prevent that?  

Any help would be great appreciated.

TIA

We are experiencing a critical issue with the RadPdfViewer control after upgrading to version 2024.4.1113. Previously, we were using version 2017.X and everything worked correctly.

After the upgrade, when some users try to load PDFs in the viewer, the documents are either:

• Completely blank,

• Filled with black squares,

• Or displayed in a distorted/incorrect format.

The issue is inconsistent — the same PDF files that display incorrectly for some users render just fine for others. All users are accessing the same application via a Windows RDS (Remote Desktop Services) environment.

What makes this even more confusing is that:

• The issue only affects certain users on the RDS server.

• The exact same PDF can be opened successfully by one user but fails for another.

• The application and environment are otherwise identical between users.

We’ve confirmed that the issue started only after upgrading the Telerik controls to the latest version.

Can you please assist us in identifying the cause and provide any recommendations or patches that could resolve this issue?

Environment:

• Telerik UI for WinForms v2024.4.1113

• Windows Server with RDS

• .NET Framework version: 4.7.1

• Application in VB.NET (WinForms)

Please let us know if any logs, test files, or further information is required.

I have a RadPageView in Strip mode with 18 tabs on it.

When the form is created I set the tabs to two rows, with 9 on each row, using this approach:

As the form is resized, I recalculate and set the width of the tabs (RadPageViewPage.ItemSize) so that they will continue to fit.

When I resize the form by dragging this works - the tabs resize and I can see all 9 on each row.

However, when I minimize/maximize the form the tabs are not resized (although I can see that the sizes are set correctly). If I hide and then reshow the application (by clicking on the icon in the taskbar) then I see the sizes are again set (to the same value) and this time they are redrawn, so show correctly.

Maximized (new width set but tabs aren't redrawn):

Hide then show (no other changes - the widths are set but to the same values as in the above image):

Similarly...

Minimize (new width set but tabs aren't redrawn, so they overflow to the right):



Hide then show (no other changes - the widths are set but to the same values as in the above image):



I have tried calling Refresh() on the RadPageView control and the RadPageViewStripElement, but to no avail.

So, is there any way to force the tabs to be redrawn when I set the new width?

Or is there an alternative solution?

Is it possible to assign an SVG image to use as the image displayed in the RadMessageBox? 

I notice that PictureBox is used rather than RadPictureBox, RadPictureBox supports SVG and it seems that PictureBox does not. Is there a reason why it cannot use RadPictrureBox?

The reason I ask, is that when specifying the image directly, it does not scale nicely when used on monitors with different DPI.

Thanks
Toby

I have a scenario where we need to manually size and position all of the controls in a certain window.  We need the size/position to be the same regardless of the DPI scaling on the system.  For standard Winforms controls, I can simply set the Window's AutoScaleMode property to 'None'.  That will prevent the controls from auto-scaling as desired.  However, if I have any Telerik controls in the Window, they are always automatically scaled no matter what I set the AutoScaleMode property to.

I know that there is a static RadControl.EnableDpiScaling property that can be used.  If I set that to false, then that will indeed disable auto-scaling for any Telerik controls.  However, that is a global setting.  I do not want to disable auto-scaling across the entire application.  I just need to disable it for a particular window.

Is this possible?

Thanks,

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
