How to use GIF in RadGridView

Hello,

I'm trying to implement GIF for my GridView but it isn't animated. Does GridView support GIFs?

My example:

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:NotWorkingGif"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" x:Class="NotWorkingGif.MainWindow"
        mc:Ignorable="d"
        DataContext="{Binding RelativeSource={RelativeSource Self}}"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <telerik:RadGridView ItemsSource="{Binding Collection}" AutoGenerateColumns="False">
            <telerik:RadGridView.Columns>
                <telerik:GridViewImageColumn DataMemberBinding="{Binding ImageUri}" Header="" ImageStretch="None" ImageHeight="16" ImageWidth="16" />
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>
</Window>

namespace NotWorkingGif
{
    using System;
    using System.Collections.ObjectModel;
    using System.ComponentModel;
    using System.Windows;

    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public ObservableCollection<TestClass> Collection { get; set; } = new ObservableCollection<TestClass>();

        public MainWindow()
        {
            InitializeComponent();

            this.Collection.Add(new TestClass() { ImageUri = new Uri(@"path to GIF image") });
        }
    }

    public class TestClass : INotifyPropertyChanged
    {
        private Uri imageUri;
        public Uri ImageUri
        {
            get => imageUri;

            set
            {
                imageUri = value;
                this.PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("ImageUri"));
            }
        }

        public event PropertyChangedEventHandler PropertyChanged;
    }
}

PropertyGrid questions

Hello,

We are evaluating the PropertyGrid control and have a few questions.

1. When using Nested Properties, I am overriding ToString to display the child property values in the parent. However how do I get this string to update when the child properties are updated?

2. Is there a way to conditionally disable properties based on the values of other properties?

3. When using the Editor attribute with the EditorStyle.Modal option, is there a way to control the start position of the modal?

 

Thanks,
Hayley

How to make the point's color in a PointSeries changed dynamically

When I create a PointSeries chart, the point's color is determined at moment the chart is showing. But I want the point's color changed with the datasource's some content after the chart was  shown.

So I make a new PlotInfo class shown as below, and  I set DefaultVisualMaterialSelector bind to PlotInfo's ColorFlag, with a Converter.
Finally, the project doesn't work, the point's color didn't change when I modify the ColorFlag.
So does ChartView3D support this kind of abbility? And how can I get what I want?

public class PlotInfo : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;
    public double XValue { get; set; }
    public double YValue { get; set; }
    public string ZValue { get; set; }
    private string m_sColorFlag;
    public string ColorFlag
    {
        get { return m_sColorFlag;}
        set
        {
            m_sColorFlag = value;
            if(this.PropertyChanged != null)
            {
                PropertyChanged.Invoke(this, new PropertyChangedEventArgs("ColorFlag"));
            }
        }
    }
}

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Always a tab and never a backstage ?
<p>        private void RadRibbonView_SelectionChanged(object sender, RadSelectionChangedEventArgs e)<br>        {</p><p>              var ribbon = (sender as RadRibbonView);</p><p>              if (ribbon.SelectedItem is RadRibbonTab)<br>              {<br>                  //DO STUFF<br>              }<br>              else if (ribbon.SelectedItem is RadRibbonBackstage)<br>              {<br>                  //DO OTHER STUFF<br>        }</p>

If I click on the backstage, this always triggers as a tab....which is causing me many problems.

Keep backstage open after an event within it ?

Hi,

We have an option to close our app in our Backstage panel:

var result = MessageBox.Show(unsavedChangesMsg, Properties.Resources.MessageBoxTitle_Confirmation, MessageBoxButton.OKCancel, MessageBoxImage.Question);

...if the user selected "Cancel" then the ribbon goes to last tab selected instead of staying in the backstage. The backstage isn't considered to be a tab it seems, so keeping it open is problematic it seems. 

I've tried:

- Hiding all tabs.

- Unselecting all tabs.

- MasterRadRibbonView.SelectedIndex = -1;

- MasterRadRibbonView.SelectedItem = MasterRadRibbonView.Backstage;

- IsBackstageOpen = true; //databinding

...and a few other things, but when the screen comes back after the user exits out of the pop-up window, the last tab is loaded, when we want it to stay on the Backstage until the user selects a tab themselves.

RibbonTab IsSelected issue in RibbonView
Hi,

I have a RadRibbonView with RadRibbonTab inside it to display Module names.
The itemsource of RadRibbonView is set with my modules and these modules are converted to tabs at runtime using a converter to the ItemSource.
From the converter, I set the first tab as IsSelected= true and it set correctly and higlights the specific tab.
But the details/contents of that tab is not displayed.
Ie: OnSelectionTabChanged event doesn't fire in this case.
Where when I click a different tab, it works fine. but when i click the first tab again, it doesn't work.
When I checked using WPF inspector, i can see that IsSelected property of the first tab is always true even when i select a different tab.
any help?

am using 2013 Q1.
The same code was working perfectly whern i used rabribbontab. Now am converting this to radribbonview ince ribbontab doesnt exists in the new release.

Cheers

How can I display only the spellchecker and the clipboard functions for a RichTextBox in the ConextMenu? All functions to format the text should be hidden.
