Copy some text from the introduction docs page:
Paste in RadRichTextEditor from the Demo app:
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.
When exporting a RadFixedDocument, which contains a signature added with PdfProcessing a NotSupportedException is thrown: 'Stream does not support reading.'
Resolution: When exporting a digitally signed document a stream that allows both reading and writing should be passed to the PdfFormatProvider.
Example:
Stream outputStream = new FileStream("path", FileMode.OpenOrCreate, FileAccess.ReadWrite)
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,
I have made an override for class GridViewDataRowInfo (called GridViewDataRowInfoPlus)
Every time a new row is created by RadGridView, I expect OnCreateRowInfo to be called, so I can return my own instance of GridViewDataRowInfoPlus.
This goes well until a user enters new data in a new row and when this row is added the grid, OnCreateRowInfo is not being called and an instance of GridViewDataRowInfo is added to the grid.
For me that is unexpected and undesirable. Maybe I am doing it wrong. In that case: What is the correct way to intercept the row-creation-process and return instances of my own type?
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.

In the method MasterGridViewTemplate.PasteDataToRow the next piece is code is located:
if (CurrentView.ViewTemplate.Columns[columnIndex].DataType == typeof(string))
{
if (column is GridViewTextBoxColumn viewTextBoxColumn && viewTextBoxColumn.MaxLength > 0 && rowData[rowIndex].Length > viewTextBoxColumn.MaxLength)
obj = rowData[rowIndex].Substring(0, viewTextBoxColumn.MaxLength);
}
When I create a new form-class, which derives from RadFrom, and I override the method OnLoad, then OnLoad is called during construction. This should never happen!
As Microsoft states: "The OnLoad method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class."
See: https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.form.onload?view=windowsdesktop-6.0
The OnLoad method can be used to load controls with data. But these controls are not even initialized, because the method InitializeComponent has not been called yet.
Hi,
An HTTP Request returns me an error in HTML format. Please see img001. This image was capture in debug mode in Visual Studio.
When I want to show a MessageBox or a Label with this HTML, appears like in img002.
Thank you!
The HTML text is:
<!doctype html><html lang="en"><head><title>HTTP Status 401 – Unauthorized</title><style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {color:white;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style></head><body><h1>HTTP Status 401 – Unauthorized</h1><hr class="line" /><p><b>Type</b> Status Report</p><p><b>Message</b> Unauthorized</p><p><b>Description</b> The request has not been applied because it lacks valid authentication credentials for the target resource.</p><hr class="line" /><h3>Apache Tomcat/8.5.65</h3></body></html>
So, at this point this seems to be a possible bug. The template project did not setup correctly. I have literally done nothing other than download and install Telerik WinForms today and then try to create this project. This _should_ work or give me instructions of further setup that I have to do manually.
I did try a couple other things, but also failed to get things working.

The following code to make the headers bold in a RadGridView. After upgrading to different 2022 versions from 2021, this code causes a Parameter is not valid error in ((System.ComponentModel.ISupportInitialize)(this.RadGridView1.MasterTemplate)).EndInit();
If I comment out the code and run then there is no error generated.
void
radGridView1_ViewCellFormatting(
object
sender, CellFormattingEventArgs e)
{
if
(e.CellElement
is
GridHeaderCellElement)
{
e.CellElement.Font = myCustomFont;
}
}
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

Hi. it was great to see the option "ImageOnly", for columns of small width, where only the image is placed in the header, and the "HederText" property was set, for the correct display of the grouping field
GridViewDataColumn column;
column.HeaderText = "Счет";
column.HeaderImage = ...; // some img
column.TextImageRelation = TextImageRelation.Overlay;
GridViewDataColumn column;
column.HeaderText = "";
column.HeaderImage = ...; // some img
column.TextImageRelation = TextImageRelation.Overlay;
it’s impossible to choose one thing, either an ugly header, or a grouping without a description
How to reproduce: check the attached project: Workaround: when the form is opened in the designer make sure that all pages are made visible at least ones so the controls are initialized, before attempting to access collection editors via properties window
