The issue is reproducible only on Windows XP. On newer versions of windows, the images are rendered as expected.

WORKAROUND: You may try implementing custom filter that handles the CMYK scenario. How to implement custom DCTDecode filter is described in this documentation article:
https://docs.telerik.com/devtools/winforms/pdfviewer/customize-and-extensibility/customize-pdf-rendering

Some other charting frameworks support ‘dynamic’ graphs/diagrams, where the graph shows nodes and links, and the user can drag the nodes around the page, and the other nodes are pulled around it. This is a great way to visualise and explore this kind of node+link data. Its also a great way to sell and app, as it looks cool.

Hi,

I want to hide some columns of the table I received from Excel on RadGridView.

Fatching data from sql database in gridViewCommboBoxColumn select the value then retrieve data other column in the same Rows windows application in Vb.net

The filter UI controls in ASP.NET Core and MVC are really nice, see filter. Can you include the same controls and UI be included in Winforms and WPF?

Hi everybody

 

I m try use the class CustomDragandDrop on radtreeview but i have a issue, 

if i use the next example, i dont have any problem:

      

   protected void BindRadTreeView()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("Id", typeof(string));
            dt.Columns.Add("Title", typeof(string));
            dt.Columns.Add("ParentId", typeof(string));

            string parentId = string.Empty;
            string childId = string.Empty;
            for (int i = 0; i < 2; i++)
            {
                parentId = Guid.NewGuid().ToString();
                dt.Rows.Add(parentId, "Node" + i, null);
                for (int j = 0; j < 5; j++)
                {
                    childId = Guid.NewGuid().ToString();
                    dt.Rows.Add(childId, "SubNode" + i + "." + j, parentId);
                }
            }

            this.radTreeView1.ChildMember = "Id";
            this.radTreeView1.ParentMember = "ParentId";
            this.radTreeView1.DisplayMember = "Title";
            this.radTreeView1.DataSource = dt;


        }

 

i can drag and drop correctly

 

but the problem is when i binding the Radtreeview

 

                       

    protected void llenatreeview1() {

            dtTablas = dat.consultaBD();

            DataTable dt = new DataTable();
            dtCopi.Columns.Add("Id", typeof(string));
            dtCopi.Columns.Add("Title", typeof(string));
            dtCopi.Columns.Add("ParentId", typeof(string));

            string parentId = string.Empty;
            string Id = string.Empty;
            string title = string.Empty;
            foreach (DataRow row in dtTablas.Rows)
            {
                parentId = row["ParentId"].ToString();     

                Id = row["Id"].ToString();
                title = row["Title"].ToString();

                if (parentId == "")
                    dt.Rows.Add(Id, title, null);
                else
                    dt.Rows.Add(Id, title, parentId);
            }

            radTreeView2.ChildMember = "Id";
            radTreeView2.ParentMember = "ParentId";
            radTreeView2.DisplayMember = "Title";
            radTreeView2.DataSource = dt;
        }

first is freeze and then appears the error.

when i drag and drop appears then next error:

System.StackOverflowException

 

what am I doing wrong please your help. thanks

GridView has a default text alignment for new columns as 'MiddleCenter'.

Default alignment for new GridViewDataRowInfo is 'left'.

Please can these be the same ?

Dear Sir,

I’m a retired computer analyst and program for my own enjoyment.

I recently downloaded your UI for Winforms product and played with your Image editor control.

A very nice control indeed. It does some great manipulations of images.

It would be even more flexible if a user were able to add their controls to the radImageEditor control, have access to the loaded image, and be able to add further options to be able to edit images.

Just a thought.

Kind regards

Phil Sargeant

 

 

Dear,

I wonder if it is possible to consult the release history by product & control & version, next to the (already existing) release history by product & version & control?

This feature has benifits:

• see how a given control evolves in time
• quickly find if a bug/feature has been implemented by control

This request can be applied for all your products.

Kind regards,

Peter

Hi guys,

              It would be great to be able to set the day start/finish times in your Scheduler.

Your Scheduler control is fantastic, but I am building a Scheduler for a company that operates over 24hrs and the shift hours are

6am - 6pm

6pm - 6am

both shifts are classed as being the same day even though the nightshift crosses over to the next day.

 

I would like to be able to adjust the 24hr period that defines a day so that in month view the appointment will not carry over to the next shift.

and in day view, the schedule will start at 6am and go through to 6am.

If you could implement this, your scheduler control would be even more powerful and awesome.

Thanks!

Have the ability to embed the colour picker in our own forms, with onChange event

Hi,

We are using Telerik UI WinForms in our project. Current built-in themes are not suitable for our project requirements. We need Visual Studio 2019 Theme for UI WinForms.

As mentioned in the Telerik blog, the latest R3 2019 release of Telerik UI for WPF and Telerik UI for Silverlight is having Visual Studio 2019 Theme.

When can we expect Visual Studio 2019 Theme for UI WinForms? 

This theme is available in WPF suite. We have the Light and Dark variations as well. 

http://demos.telerik.com/aspnet-ajax/treelist/examples/overview/defaultcs.aspx

Right now, when a VirtualGridDateTimeEditor is displayed in a RadVirtualGrid, and the user chooses to enter the date (and not use the date time picker), then the user has to enter the date inclusing the separators.

So a Dutch date has format: "dd-MM-yyyy", and the user has to enter "31-12-2023", including the dashes.

Hereby my request for a new feature:  Entering dates without the separators / dashes, thus: "3112023". So at the moment the user enters two digits, move to the next segment, etc. The request goes for the time segments.

This would be a performance gain while doing a lot of data entry.

Background: With many people having moved to working remotely, collaboration is a much larger part of any enterprise applications. As such, it would be highly beneficial to add real time collaboration capabilities to editor controls, more specifically the RadRichTextEditor control. It would work similarly to how MS Word works when more than one user is editing a document at the same time.

Scenario: Assume you have and WinForms application where there is a form that contains a RadRichTextEditor. The content for this control is populated from a centralized database. This content is editable by users of the application. Lets say that you have two users (User A and User B) editing this content at the same time. Currently, User A cannot see what User B is doing in real-time, and vice-versa. Each time one of the users saves the content, it will overwrite any changes made by the other user.

Desired outcome: If the users in the above scenario are using MS Word, each user would see that someone else is currently editing the document and the other user's changes would be displayed in real-time. This same outcome should be made more readily available with the Telerik editors, primarily the RadRichTextEditor, so that when two users are editing the same content, they would see each others' changes in real-time.

I know this is possible using SignalR and a bit of code, but I think it would be beneficial for the RadRichTextEditor to have better "out of the box" support for this feature.

I am aware of a web-based control that has this feature. Specifically, the CKEditor (https://ckeditor.com/) control has the features I am requesting. However, I am looking at WinForms as opposed to web.

Hi,

Is there a way to get version and producer metadata from imported PDF files? 

Here is how it looks in AdobeReader

Thanks in advance,

The version of Telerik products is requested as information where submitting a support ticket. In case one forgot the version currently installed, there is no way to find it (may be I am the only one who don't know). Usually most software provide such information in the "About" box. I found it difficult and not very useful that the "About" menu of Telerik connect to the Progress Home Page instead of displaying some useful information about the current installation (user name, version, installed components, license status, etc....). There are already many other actions (request support, online documentation, etc...) that connect to the web site. The "About" box should just be displayed within VS and provide information on the installation. Or at least you link it to the Progress Control Panel and adding a page for information I mentioned and more that user may need to know when needed.

Below is an example from VS.

Add the ability to add a richTextBox cell type to the RadGridView and have the ability to link it to a data source and to a RichTextEditorRibbonBar.

Eery time I use the GridView, I have to remember to un-select the last item in the list.

This is almost always to wrong thing to be selected - so why select it by default?

..and the way to swith this 'feaure' off isn't obvious - I always have to look it up....RadGridView1.CurrentRow = Nothing
