ChartView - ChartGrid - Grid disappears with empty series

Hello team,

As said in the title, I have a Chart with a cartesian grid visible and working fine. The problem is when I add a series programmatically and the series data is empty (see img.2): my chart displays the new axis as expected with no values since there is no data for the series, but the grid disappears.

Img.1 : Two series with data. The grid is visible fine.

Img.2: Two series with one empty. The grid disappears.

Why do some C# applications have an app.config file and others do not?

Why do some C# applications have an app.config file and others do not? Both of these solutions were initialized as Visual C# Windows Form Applications.

This one I created in Visual Studio Community version:

This screen capture bit is from a youtube tutorial. I followed along with the instructor in the video and He created it with a menu selection as a Visual C# -> Windows Form Application.

I tried following along with the tutorial and I noticed that the instructor's IDE, Visual Studio Community version, had a Solution Explorer that included the app.config file. I am curious and concerned because I believe system settings can be entered into the app.config file and so his code will be different from mine and my code might not even run at all.

Center icon in floating window

Hi,

I am adding a custom icon into a floating docking window using this code:

    private void SetHeaderIcon(ToolWindow toolWindow, Icon icon)
    {
      toolWindow.FloatingParent.Icon = icon;
      toolWindow.FloatingParent.ShowIcon = icon != null;
      toolWindow.FloatingParent.FormElement.TitleBar.IconPrimitive.Visibility = icon != null ? ElementVisibility.Visible : ElementVisibility.Collapsed;
    }

The icon is added correctly, but it's not centered. I don't know if it's a problem of the theme, or it's just expected behaviour.

I added 2 screenshots of what I see with a custom icon, and with the default icon.

Is there a way to add margins or center it?

I'm using Telerik for WinForms 2018.3.911.40

Thank you.

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

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:

        _outerContainer.Children.Add(_continueArrow);
        DockLayoutPanel.SetDock(_continueArrow, Telerik.WinControls.Layouts.Dock.Right);
        _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.

Alessandro
