Import hover style for a link in HTML:

a:hover {
            color: #3ca9f6
}

Alow reordering and drag-and-drop of column's group in ColumnGroupsViewDefinition.

Documentation about High-DPI mechanisms available on the website is very outdated and mostly does not consider the changes and improvements that Microsoft made with .net 7.0 and 8.0.

What's needed is thorough documentation about Telerik's behavior in comparison with the different situations on .net Framework 4.9 and the major .net Versions 6.0, 7.0, and 8.0.

Kind regards

Please add support for adding a background image to the RadDiagram. This could be used for example for a floor plan application, where the background image would be a map of a building.

Please refer to the attached gif file. The activated editor for the text field shouldn't change the font. 

JavaScript actions cause a script to be compiled and executed by the JavaScript interpreter. Depending on the nature of the script, the values of the interactive form fields in the document can be validated or updated or the visual appearances of the fields can be changed.

   

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!

When a developer set the RadForm.ThemeName property and then drag any controls onto the form, they will get automatically this theme applied to the control's ThemeName property. However, if you already have some controls on the form with ThemeName = "X" and you change RadForm.ThemeName to "Y", all controls' ThemeName should be changed to the new RadForm.ThemeName as well.

To be accessible and compliant with our organizations standards, the search bar that can be enabled in the gridview should be accessible by pressing TAB and shift TAB. Right now the only way to select the search by keyboard is pressing Control F, but the up/down arrows and the search settings cog wheel cannot be accessed via the keyboard.

As of right now, the user cannot also select the column headers using the keyboard, which in turn means you cannot sort by a column with a keyboard.

 

 

When RadOpenFileDialog is opened, open an Explorer window , select a file, copy it and paste in the folder displayed from the RadOpenFileDialog. If the same operation is performed using a standard WinForms OpenFile dialog the pasted file is selected after the paste operation.

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?

In MergeFields the general switch may be used to format the Result Text. The text may appear in lowercase, uppercase, title case and so on.

When a cell has DBNull.Value or null, its value is not read by Narrator since it is considered as empty string. In this case, the NullValue property of the column should be considered.

RadVirtualGrid is created to support a million records or more. Still it contains some "heavy" operations like CopySelection/CutSelection/Paste which can take a long time.

I would like to intercept these methods so I can show a "Please wait"-window during the operation. Furthermore I have the need to set a flag to true when such a operation is executing. 

We work with a RadGridView with 145000 rows and 4 columns. We use copy-paste to move data around from other apps and the application with build with Telerik.

When we copy a flat file (with tabs delimited fields) and we paste it to the RadGridView, the whole process is painfully slow. The function to retrieve the data from the clipboard takes minutes (maybe hours, I cancelled it). It tracked the cause down to the StringTokenizer class. The tokenizer splits the string up into separate fields. But after extracting a field it creates a new copy of that string (containing about 10MB of data) minus the field. I patched it (with HarmonyX) and now it takes only one second:

static class StringTokenizerPerformancePatch
{
	static private readonly InstanceFieldAccessor<StringTokenizer, LinkedList<string>> _tokens = new InstanceFieldAccessor< StringTokenizer, LinkedList<string>>("tokens");
	static private readonly InstanceFieldAccessor<StringTokenizer, string> _sourceString = new InstanceFieldAccessor<StringTokenizer, string>("sourceString");
	static private readonly InstanceFieldAccessor< StringTokenizer, string> _delimiter = new InstanceFieldAccessor<StringTokenizer, string>("delimiter");
	static private readonly InstanceFieldAccessor< StringTokenizer, IEnumerator<string>> _enumerator = new InstanceFieldAccessor<StringTokenizer, IEnumerator<string>>("enumerator");

	[HarmonyPatch(typeof(StringTokenizer), "Tokenize")]
	staticclassPatch_StringTokenizer_Tokenize
	{
		static bool Prefix(StringTokenizer __instance)
		{
			var tokens = _tokens.GetValue(__instance);
			var sourceString = _sourceString.GetValue(__instance);
			var delimiter = _delimiter.GetValue(__instance);
			Tokenize(tokens, sourceString, delimiter);
			_enumerator.SetValue(__instance, tokens.GetEnumerator());
			returnfalse;
		}

		static private void Tokenize(LinkedList<string> tokens, string text, string delimiter)
		{
			tokens.Clear();
			
			if (string.IsNullOrEmpty(text))
				return;

			int index = 0;
			while(true)
			{
				var index2 = text.IndexOf(delimiter, index, StringComparison.Ordinal);
				if (index2 < 0)
				{
					tokens.AddLast(text.Substring(index));
					break;
				}

				string token = text.Substring(index, index2 - index);
				tokens.AddLast(token);
				index = index2 + delimiter.Length;
			}
		}
	}
}

Please update your tokanizer to increase performance. While you are at it:

• If delimiters are one character, why not use String.Split?
• Why use a LinkedList?
