Hello,

I have a RadGallery control with a few items in it.

I want my items to behave like radio buttons from a single group.
 
Currently if I'm selecting one item and then another, the other one gets unselected, which I like.
However, if I'm selecting one item and then clicking on it again, it gets unselected,  similar to checkbox behavior, which I don't like.

In all of your examples, including ones from previous versions, a click on an item that has already been selected, gets ignored, which is the behavior that I want, for example:

<telerik:RadGallery ViewportWidth="157" ViewportHeight="184" ItemWidth="156"
        ItemHeight="26">
    <telerik:RadGalleryItem Image="{Binding Underline1}"
            ToolTipService.ToolTip="Underline" />
    <telerik:RadGalleryItem Image="{Binding Underline2}"
            ToolTipService.ToolTip="Double underline" />
    <telerik:RadGalleryItem Image="{Binding Underline3}"
            ToolTipService.ToolTip="Thick underline" />
    <telerik:RadGalleryItem Image="{Binding Underline4}"
            ToolTipService.ToolTip="Dotted underline" />
    <telerik:RadGalleryItem Image="{Binding Underline5}"
            ToolTipService.ToolTip="Dashed underline" />
    <telerik:RadGalleryItem Image="{Binding Underline6}"
            ToolTipService.ToolTip="Dot-dash underline" />
    <telerik:RadGalleryItem Image="{Binding Underline7}"
            ToolTipService.ToolTip="Dot-dot-dash underline" />
    <telerik:RadGalleryItem Image="{Binding Underline8}"
            ToolTipService.ToolTip="Wave underline" />
</telerik:RadGallery>

The difference between your code and mine is that you're populating your gallery with RadGalleryItems and I'm populating it using ItemsSource and ItemTemplate, My ItemTemplate is similar to this:
<DataTemplate>
    <StackPanel>
        <Image Source="{Binding Image}" />
        <TextBlock Text ="{Binding Text}" />
    </StackPanel>
</DataTemplate>

Also this doesn't have the desired behavior:
<telerik:RadGallery ViewportWidth="157" ViewportHeight="184" ItemWidth="156"
        ItemHeight="26">
    <TextBlock Text="16253765" />
    <TextBlock Text="16253765" />
    <TextBlock Text="16253765" />
    <TextBlock Text="16253765" />
    <TextBlock Text="16253765" />
</telerik:RadGallery>
It seems that it only works with items that are inside RadGalleryItem, but I thought that it should happen implicitly.

Hope that someone can help.

Thanks,
Evgeny

Hello Evgeny,

This is a bug in the RadRibbonBar indeed. We logged it in our PITS(RibbonBar: When Gallery is bound or filled with non-RadgalleryItems, clicking on a selected item deselects it which is wrong) where you will be soon able to vote for. Thank you for your cooperation. We also updated your telerik account points.
