Repro-steps

1. Create a RadGridView
2. Add a GridViewDecimalColumn
3. Add a GridViewSummaryRowItem with a GridViewSummaryItem which:
   1. calculates the average of the values in the decimal column
   2. formats the value to two decimals after the decimal point: {0:0.00}
4. Make an event handler for ViewCellFormatting.
5. Add some rows with values to the grid.
6. In the event handler, try to read ((GridSummaryCellElement)e.CellElement).Value.

Actual behavior

The value contains a string representing the formatted and rounded value of the average of all values.

Expected behavior

The value contains a raw, not rounded,  not formatted, decimal value. 

Remarks

I expect this behavior since GridSummaryCellElement has two properties: Text and Value.
I expect those to have difference functions. Value to hold the actual calculated value, and Text to hold the formatted, round string-equivalent.

Another reason why I expect this, is that Value is of type object, not of type string. So expect a value corresponding to the original datatype of the column and/or the result of the calculation.

Follow-up questions

1. In what scenario may I expect in Value another data type that string?
2. How, during the event handler, can I retrieve the original calculated value (with using parsing, since that is slow and does not contain all the digits).

 

 

When I use the new project wizard provided by Microsoft for a new windows forms project it lets me select the target .net version

When I do the same with the Telerik wizard, it does not let me choose what .net Version I'm targeting and does not generate the optimal code for the target version. For example when I target .net 9.0 with high dpi support, it should generate API calls for High DPI, not an entry in the app manifest. IMHO the generated code should be as close to the Microsoft Standard for the targeted .net version as possible. 

 

The AccessibleObjects in NetCore have ComVisible=False and this causes a handled exception. This attribute is not required in NetCore and could be removed.

Hi, all. I am using the example you guys provide in your website and you can get from here: https://www.telerik.com/blogs/winforms-scaling-at-large-dpi-settings-is-it-even-possible-#example

As you can see in the image, I open the form in my main screen with Scale 100%. I have a second screen running in 150%. When I grab the form near to the left edge side of it, it resizes in one way, what I believe that is the correct way. However, if you grab the form near to right edge side, near the minimize, maximize and close button, it resizes differently. We have several users using our application and we are not able to fix this scalling issue, even in your own example. Could you guys have a look at it and prioritize? This kind of issue has been around for a long time without a final resolution. if not possible, let us know that we will have to decide move to another development tool.

Telerik version: 2024.2.514

I would like to see a new property added to the RadLabel control: Style. Style is an enumeration with layout styles like in MS-Word: 

• Normal
• Title
• Heading 1
• Heading 2
• etc.

When the style is applied, the styling (font, color, background, etc.) is applied conform the currently active Theme. Therefor all themes need to be expended to support this setting.

Of course the enum label 'Custom' should be present (or null) when a user tries to override the style-related properties (like font, color, background, etc.)

This is very usefull when a programmer wants to build his own form (with or without Layout / Flow controls).

Telerik already uses it a bit themselves: Some (data entry) controls already generate (group) headers and captions in there forms. 

Improve keyboard accessibility in RadGridView.

In this case, we have an MS standard Form with control position on the form. Each of the controls has the right anchor. Moving the form to a monitor with a higher resolution messed up the size of the controls. 

Set IsThreeState property to true and choose ToggleState to Indeterminate.

When I update to version 2024.3.806 I get a build error :

Please consider integration / enhancement of the following rich sting rendering capabilities enabling performance for quick rich string related rendering tasks, providing further alternatives to GDI and GDI+ based tiresome and limited solutions, allowing scaling: https://github.com/toptensoftware/RichTextKit

 

 

Control for uploading files to storage.

Add new ThemePicker component that allows dynamic themes changes. 

I have a custom Fluent theme as a package, it would be nice if there was a way to load packages (Embedded Resource or files) with the RadThemeManager.

Rather than typing this: Telerik.WinControls.ThemeResolutionService.LoadPackageResource("GUI.Themes.Fluent_Custom.tssp");

Right now the RadThemeManager only supports XML files. Feeding it a tssp file doesn't work.

 

For it to show up in design-time I have to assign it all of the unpackaged XML files and then delete the RadThemeManager for the theme to show up, otherwise the load time is like 7 seconds, where as embedded packages load super fast.

The fluent theme has a lot of XML files and this is a huge pain, supporting 1 Embedded Resource tssp package would be nice.

 

Would also be nice if the RadThemeManager could apply/change a theme globally somewhere in the SmartTag menu or RadThemeManager properties.

Instead of having to type this: ThemeResolutionService.ApplicationThemeName = "Fluent_Custom";

Hi, the new feauture Merge Cells is very nice but the alignment is only at the center.

Can I align the merged cells in the same mode of the column?

Thanks, Fabrizio

We should enable the out-of-process designer in .NET Framework projects so that old third party 32-bit and ActiveX/COM controls can be loaded inside Visual Studio 2022.

I’m converting 20+ year old c# .net winform software that a clever internal ex dev wrote a themed control suite for. I’ve been working with those controls for almost the same length of time but am recently tasked with updating the whole app as customers are experiencing fall overs on some modern versions of Windows. Ive had the pleasure of (almost quietly ?) converting/updating by using Telerik for many years as my choice of replacement themed control systems.

Conversion experience has been pretty good, except for combo boxes, probably listboxes too (sorry guys Im writing this in bed at 5am so can’t/won’t just go testing). I did try, i think, using your conversion wizards without success. I do wish that you’d let us add any type of object to a combobox.item array in the same way that microsoft winform control allows.
Ive also noticed that some events dont occur in telerik, eg index changed need to be switched to valuechanged and these are only spotted when testing, which means extra work.

anyway. Bless an thanks to you all for my good experience with Progress/Telerik. Im old, poorly and crumbly now and wont be around much longer. May i last long enough not to need a pension to survive and i hope each of you invests in enough private pension to give yourselves a decent holiday or three per year ;) 

 

After more than 10 years this is STILL a Bug. 

https://feedback.telerik.com/winforms/1369181-fix-radgroupbox-with-collapsed-header-does-not-fill-the-entire-content-if-there-is-a-docked-child-control-inside-the-groupbox

The groupbox header does not collapse when I put a table layout panel inside of it.

 

Is this product (Telerik for winforms) still being supported? Or should I be looking elsewhere for a different controls toolkit solution for my company?
