Dear Support,

I noticed one strange thing with radgridview, under WPF (see the screenshot below)

This is a complex production planner screen, and as far as i just click the cells with mouse it works perfectly. But when i use the arrow keys to navigate between cells two thing can happen:

1. If i push less frequently the actual cell switches without problem.

2. If i push quicker, or if i hold the button the grid leaves random selected cells behind.

There are a few things in the SelectedCellsChanged event, which runs in ~200ms. This 200ms is mostly an SQL query, i run it each time to fill some other fields based on the selected cell. As i guess: if i switch faster than this, the bug appears, if i select slower than this, then it switches the cell without any problem. 

Do you have any advice how can i solve this? I tried to put .unselectall after each, but it just made it worse.

Thanks

Peter

Dear Support

I use radgridview in WPF (vb.net), and i spent deays already to figure out how to get the index of the current row.

If the SelectionUnit = Fullrow then its easy, because:

     Dim CurrentRow As Integer = rgv_STATIONS.Items.IndexOf(rgv_STATIONS.SelectedItem)

will give it back . But unfortunately i have to use SelectionUnit = Cell. With this setting the above CurrentRow variable always gets -1.

I need to know it in case of CellEditEnded and at SelectedCellsChanged events. Getting the column index in the same places is easy, but please help me to find the rowindex as well, i lost half of my hair already due to this :)

Thank you

Peter

Hi 

I Found Gridview bug.

Hi,

I am using the RadRadialMenu to navigate a dynamically built structure (arbitrary depth, arbitrary width) - I know the width can become an issue as item sectors can become very small, but this is contained.

It works really great and the users love it, but each time the menu refreshes it eats up memory that does not get released again.

If I strip out the actual building of the RadialMenuItems (custom class RadialMenuItemVM that implements IRadialMenuItem) then there is no build-up of memory.

I have created a small demo app that resembles the full app but with a very limited structure and content. On refreshing the menuitems the memory usage in VisualStudio diagnostic session starts to grow. With the limited size of the structure, the memory growth is slow, but it is definitely noticeable after a number of refreshes.

The one thing that I did notice is that the destructor of the RadialMenuItemVM instances only gets called upon closing the window. There seems to be a sticky reference that keeps them alive until the actual radial menu is destroyed.

Sample Project attached. Note that I have removed Telerik lib contents to reduce size so references might require updating

Hello,

In my application I try to change the colors from Fluent theme globaly. Unfortunately it seems my changes are ignored. I'm wondering what I'm doing wrong.

To exclude any side effect related to my application I created a new WPF program (.Net Core 5) that just contains a Splash screen and a NavigationView to check if the theme settings are applied. Source code of this test program is attached.

Steps I did to change the theme:

1: I set Fluent theme as the theme of the application (according to Setting a theme using stylemanager). This works fine. Splashscreen and NavigationView appear in Fluent theme.

2: I used color theme generator (Color theme generator) to adapt the colors and copied generated code to clipboard. Pasted the code next to theme setting from 1 (tried both, before and after setting theme)

The settings are done in App.xaml.cs. My test change to Fluent theme is that I change every color to red. When I execute the program, Fluent theme looks normal (blue color, See screenshots). My expectation was that I see a lot of red.

This is the code how I try to adapt the theme:

namespace TelerikStyle
{
    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            // Set the theme
            SetTheme();

            // Show dummy splash screen
            var dataContext = (SplashScreenDataContext)RadSplashScreenManager.SplashScreenDataContext;
            dataContext.Content = "Loading Application";
            dataContext.Footer = "";
            RadSplashScreenManager.Show();
            Thread.Sleep(5000);
            RadSplashScreenManager.Close();
        }

        private void SetTheme()
        {
            StyleManager.ApplicationTheme = new FluentTheme();

            FluentPalette.Palette.AccentColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.AccentFocusedColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.AccentMouseOverColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.AccentPressedColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.AlternativeColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.BasicColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.BasicSolidColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.ComplementaryColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.IconColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.MainColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.MarkerColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.MarkerInvertedColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.MarkerMouseOverColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.MouseOverColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.PressedColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.PrimaryBackgroundColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.PrimaryColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.PrimaryMouseOverColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.ReadOnlyBackgroundColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.ReadOnlyBorderColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.ValidationColor = (Color)ColorConverter.ConvertFromString("#FFFF0000");
            FluentPalette.Palette.DisabledOpacity = 0.3;
            FluentPalette.Palette.InputOpacity = 0.6;
            FluentPalette.Palette.ReadOnlyOpacity = 0.5;
        }
    }
}

Any ideas what I miss?

Thanks and Regards

Hello,

The leftmost column of my RadGridView has cells containing a "Save" button (a disk icon you can click).

I want users to be able to click on that Save button but not on the cell itself, nor the column, because it's kinda pointless.

I tried setting IsReadOnly to true and IsEnabled to false on this GridViewColumn but it doesn't help!

Thanks for your answer!

We are updating to Telerik.Windows.Controls.GridView 2021.2.615.45.

The methods "ScrollIntoViewAsync" and "ScrollIndexIntoViewAsync" are not working as expected, in the case that a row would be partially visible:

As you see in the above screenshot - we insert a new row with "BeginInsert" and set the new row visible. Even if we call "ScrollIntoView" the row is not fully visible as expected.

The bug is located in FlatLayoutStrategy.IsRowInViewPort:

As you can see in the screen above, the logic only checks if the beginning of the row is visible - but not the full row.

Comparing it to Telerik.Windows.Controls.GridView 2014.1.331.45 - the logic worked as expected - see here:

With this old logic, the row is fully scrolled into viewport.

Can you fix this logic or give me a workaround?

https://docs.telerik.com/devtools/wpf/controls/radchartview/axes/multipleaxes#multiple-axes-and-seriesprovider - it does not provide a solution to my problem. I need a common vertical axis for all lines

Thank you

Is it possible to set a custom ‘Search as You Type’ style on the highlighted grid cells?

I have some users that are color blind and can’t read the highlighted cells, to be honest, I find the red text hard to read myself and I’m not color blind.

See attached screenshot. 

Thanks,

Richard
