As of 2024 Q2, we will deprecate .NET Framework 4.0 and .NET Core 3.1 distributions. This decision is rooted in our dedication to align with Microsoft’s recommended framework versions so that our products leverage the latest advancements in technology, security, and performance.  

We are aligning our product with Microsoft’s lowest-supported framework versions for .NET Framework and .NET, respectively. Please refer to the following blog post: Product Update for Enhanced Performance and Security (telerik.com)

using System.Windows.Forms;

namespace testGridViewKeyPress
{
    public partial class RadForm2 : Telerik.WinControls.UI.RadForm
    {
        private int count_;
        public RadForm2()
        {
            InitializeComponent();

            count_ = 0;
        }

        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {
            count_++;
            radLabel1.Text = count_.ToString();

            radGridView2.BeginUpdate();
            radGridView2.Rows.Clear();
            //I Want to Process Row Clear And Add
            radGridView2.EndUpdate();

            return true;
        }
    }
}

 


When I hold down the key, I want to clear the row of the GridView and add a new row.

However, when the number of columns increases, even if rows work is performed between BeingUpdate() and EndUpdate(),

All UI is not highlighted or updated.

If the control needs processing when in the press state like this, shouldn't I use gridview?

Or, if there is another solution, please let me know.

+What I want is for all UI to update and operate when a key is pressed.

+My telerik version 2021.3.914.40(Dev)

Hi,

My team is trying to make an update from WinForms 2015.1.331 to the Latest 2024 Q1 Update 2024.1.130. Asked me for the comparison RadGridView component features until 2015 Q1 version(current) vs the rest of improvements/features from current to 2024 Q1 version. Is there a better way to get this comparision without scrolling through all releases and noting down the features and manually analyzing?

I have 2 grids with drag and drop capability, one of them is just a simple grid with 2 columns, the other grid is a grid with 3 Hierarchical Templates that have 3 associated BindingSources.

How can I, when dragging and dropping from the simple grid to the hierarchical grid, determine which Template I am dragging the row to and add it to that Template/BindingSources?

I used exactly the example code you have here (https://docs.telerik.com/devtools/winforms/controls/gridview/rows/drag-and-drop), and indeed everything works.

I just wanted to understand if it's possible to know which Template the row is being dragged to and add it exactly to that Template.

Why do some C# applications have an app.config file and others do not? Both of these solutions were initialized as Visual C# Windows Form Applications.

This one I created in Visual Studio Community version:

This screen capture bit is from a youtube tutorial. I followed along with the instructor in the video and He created it with a menu selection as a Visual C# -> Windows Form Application.

I tried following along with the tutorial and I noticed that the instructor's IDE, Visual Studio Community version, had a Solution Explorer that included the app.config file. I am curious and concerned because I believe system settings can be entered into the app.config file and so his code will be different from mine and my code might not even run at all.

I would like to style my application with icons *like* those found on this control. I desire something modern, attractive, but simple and clean, which I think RadPdfViewerNavigator does well, problem is it only has a handful of icons. I need a much larger library to develop an entire desktop application.

This question has been asked in one form or another a few times, but I am unsatisfied with the answer.

Essentially, as a customer, I want EASY access to ALL icons available. I want to be able to VIEW them, and then CHOOSE what I want to use across my application.

Using controls like these should make that a breeze and not complicated like some of the responses I have ran across.

Additionally most of the icon stuff is geared towards web design.

I would like answers strictly for desktop application design.

Is this possible? Can some one break this down across the board for winforms on the easiest solution to view all the icons available for Telerik Winforms.

Thank you for reading and for your help in advance!

Trying to run UI for Winforms examples for a user and we have the store locked down. When I run it on the machine I get a popup stating it wants to run this

C:\Program Files\WindowsApps\Telerik.TelerikUIFormsExamples_202...\windowsstorelauncher.exe

Network location cannot be reached.

 

Does it require the store to be enabled? This is after install and just trying to run it. Yes, we can install it without issues.

Hello!

RadPageView has a setting called "ItemSpacing" that adjusts the gap between RadPageViewPage controls.

Is there any way to get a similar result for RadDock?

 

Cheers!

We’re long time Telerik subscribers. I love telerik but but i dread seeing ‘that’ notice that theres a new upgrade to the control set as i know i’ll be fiddling about with source to get things to compile. Winforms. 

Firstly, licx files arent updated with the version number of the new control set. Its a bit concerning, but at least i can do a [search/replace in files ] on old to new version number to fix this quickly.

secondly, when adding to the list of references, which file path should we be searching for an assembly? My solution has many projects and ive found several file paths. Some to the Telerik install directory (eg c:\program files(86)….), one or two from my user\username 🤯many from the lib\telerik directory beneath the solution\project directory.

i think ive finally realised that the update application works by switching out just those references from the old, to the new lib base file path for us. But id like confirmation please.

Does anyone know how to access the ApplicationMenu on a RadRibbonForm?

I'm trying to add items to the RightColumn area but so far I've not found any documentation on how to get to the Application menu that is NOT added separately but is part of the RadRibbonForm inherently.

 

Any help would be greatly appreciated!

-Curtis.
