RadToastNotification (Chat Template) - Add hidden input

Hi,

is it possible to add a hidden input in a toast notification xml, like the one in html?

something like: "<input id=\"AnswerTo\" title=\"Rispondi a...\" defaultInput=\"" + _sender + "\" type=\"text OR hidden\" visible=\"none OR false\">"

The goal I want to achieve is to pass text variables within the ToastNotification preventing editation from the user...

Thank you

Chart View w/ Legend and Tool Tip Text

Is there a way to add Tool Tip Text to the legend items that get generated? I have Tool Tip Text on the Series object, but I would like it on the Legend Items as well.

Also, one other question, is there a way to customize how the legend shows the value next to the key? Right now, our legand keys are "ABC 123". I would like to add a "-" between the KEY and the COUNT value.

TIA

Overlay Bug: After close RadOverlayManager it changes the mdi form

Hi,

I use Windows Forms as MDI and open some child form.

In one of the forms, I use the RadOverlayManager for Grids to get an Loading Screen.

Before I start the loading of the RadGridView (or something other).

RadOverlayManager.Show(RadGridView1)

And after the loading of the Grid at the end of the sub.

RadOverlayManager.Close()

But after the loading, it selects another MDI Child form, that was opend "before" these form.

Any Ideas whats wrong and how to solve these problem?

(or maybe have another solution as a loading screen/symbol for loading things)

Thank you

Custom AppointmentElement diplay problem

Hello,

I have implemented a custom AppointmentElement and I habe a small display problem with it.

Here is a screenshot:

When the area of the appointment gets to small, the arrow on the right is no longer drawn, but i want the element to always draw it and cut the text first.

Here is my implementation:

internal class CustomAppointmentElement : AppointmentElement

        _outerContainer.Children.Add(_container);

        Children.Add(_outerContainer);
    }
}

Hope you could help me solve it.

Set default file type to xlsx when saving a spreadsheet generated from stream

Hi,

I can generate a spreadsheet from stream then visualize it with a radspreadsheet and related ribbon bar, but when I save it, the default extension is always .xls, all I want is to save as default in xlsx (and maybe remove the other file type filters).

Also I was unable to set a default name for the file, how can I do that?

Thank you.

Scrolling grid view with custom column and cells visualy "shuffles" data.

Hello,

I created a custom column and cell in my grid following the progress-bar example

https://docs.telerik.com/devtools/winforms/controls/gridview/cells/creating-custom-cells

But I have modified it so that I can view either a textBoxElement or a dropDownListElement depending on what data is in the cell. It all seems to work just fine until I scroll the grid. Scrolling visualy shuffles the data in the custom column. I've tried to take the cell-formatting route but without success. Is it possible to achieve this result somehow?

RadGridView - Avoid CurrentCell auto selection

Hi,

I would like to have a grid with no cell selected by default. So every time it is loaded no CurrentCell is selected. Same when there is no selection and the grid is sorted by a column.

Right now, the grid marks the first cell as CurrentCell when it is loaded. I could solve it using the .ClearSelection() method but then I have the same problem when sorting: the first cell is marked as selected.

How can avoid this behavior and only set the CurrentCell when the user marks it?

Designer Broken with UserControl

Hi,

It seems after upgrading to the latest Nuget version of UI.for.WinForms.AllControls.Net70" (Version="2023.3.1114") I ran into the following issue when opening the designer :

System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime.Serialization.Schema, Version=0.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Le fichier spécifié est introuvable.
File name: 'System.Runtime.Serialization.Schema, Version=0.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
at System.Reflection.RuntimeAssembly.InternalLoad(AssemblyName assemblyName, StackCrawlMark& stackMark, AssemblyLoadContext assemblyLoadContext, RuntimeAssembly requestingAssembly, Boolean throwOnFileNotFound)
at System.Reflection.Assembly.Load(AssemblyName assemblyRef)
at Microsoft.DotNet.DesignTools.Server.DesignToolsServer.LoadReferencedAssemblies(AssemblyName[] referencedAssemblyNames, HashSet`1 serverDependenciesNames, CancellationToken cancellationToken)

After the designer shows up, every custom user control I'm using on it (based on Telerik controls) completely disappear.

If I make a single change and save the file, I can confirm that all of them are gone, looking at the diff with Git.

I'm wondering if it's a Telerik or a Visual Studio issue, but either way, the result is that I can't work anymore on this project.
