I want to disable all highlight in the RadAutoCompleteBox dropdown list. So I have HighlightBehavior.FindHighlightedIndex which returns -1. But, still one item in ItemsSource is highlighted. How can I fix it?

 

FYI: On entering EACH new character in the search text box, we are calling a web service which returns a list of recommended search strings from history. (This behavior is similar to google search box.) And we set that list to ItemsSource property. This service call takes a few milliseconds.

Observation: after hitting a new character in search box, FindHighlightedIndex is called, which returns -1, and after that, our service returns a new set of strings to be set in dropdown list, and that list is set to the ItemsSource property.  

 

Kindly suggest how to fix this.

Thanks.

 

Our code snippet below:

public class NoSuggestionItemHighlightBehavior : HighlightBehavior
{
    public override int FindHighlightedIndex (string searchText, System.Collections.IList filteredItems, IEnumerable<object> escapedItems, string textSearchPath, TextSearchMode textSearchMode)
    {
       return -1;
    }
}

 

<telerik:RadAutoCompleteBox x:Name="textBox_Search"
ItemsSource="{Binding AutoCompleteList}"
SelectionMode="Single"
TextSearchMode="Contains"
BorderThickness="0"
HighlightBehavior="{StaticResource NoSuggestionItemHighlightBehavior}"
SearchText="{Binding SearchText, Mode=TwoWay}">

Dear Telerik team,

We have a RadGridView with localised columns and we would like to use string that remain same for all localised value. In order to achieve we use UniqueName="Id" and Set AutomationProperties.AutomationId="{Binding UniqueName, RelativeSource={RelativeSource Self}}" but when we run application the Header which is a localised string always get precedence and we end up with header value.

Here is a code there we were using for defining columns

<telerik:GridViewDataColumn
                    x:Name="OrderId"
                    Width="auto"
                    AutomationProperties.AutomationId="{Binding UniqueName, RelativeSource={RelativeSource Self}}"                     DataMemberBinding="{Binding Id}"
                    Header="{x:Static resources:Resources.Id}"
                    Style="{StaticResource RightAlignedRadGridViewColumnStyle}"
                    UniqueName="OrderId">

Hi,

When I try to set the padding for the Row Header in my pivot grid it causes the row expand buttons to disappear? I need to adjust the padding so the text sits correctly (in the middle not bottom) of the row.

I have attached images showing the missing expand button. Should the RowHeaderStyle maybe based on a different style?

Thanks for you help!

I have the following .xaml and it correctly colorizes the foreground on specific items when a certain condition is met (Impinged = True).
However, when I select that item, it doesn't maintain the color. I attempted the following suggestion on this thread but it didn't work. Either because I am working with Telerik or something else.

I tried this but didn't work:

Hi,

we have a strange behavior, when we bound a group filter.

                <telerik:RadScheduleView.ViewDefinitions>
                    <telerik:DayViewDefinition  GroupFilter="{Binding VmGroupFilter}" DayStartTime="06:00" DayEndTime="19:00" TimerulerMajorTickStringFormat="{}{0:H:mm}"/>
                    <telerik:WeekViewDefinition GroupFilter="{Binding VmGroupFilter}" DayStartTime="06:00" DayEndTime="19:00"/>
                    <telerik:MonthViewDefinition GroupFilter="{Binding VmGroupFilter}"/>
                </telerik:RadScheduleView.ViewDefinitions>
            </telerik:RadScheduleView>

The DayView works like expected, but now the week view is still a day view and the month view is the week view.
See attached screen shots.

Do you have any explanation for this?

We are currently using a simple map component which allows us to load our "map" as a picture (.png). I would like to use the Telerik RadMap instead because you provide several features (virtualization, zooming, layers) which are only supported in a basic way by our current component. We are displaying industrial plant maps which could be represented in "GPS" coordinates however our systems are built to use a different coordinate system. The problem is that we do NOT use shape files, a global coordinate system or such things however the RadMap component is mostly built to be used like that. I tried to use the UriImageProvider which displays my map however I don't know how to configure my coordinate system.

Our map has the following data:

- map image (.png)

- defined coordinate origin (-> e.g. bottom right of the image)

- 1 Pixel = 20mm

- drawings (polylines) based on coordinates located in a SQL DB

 

Is it possible to use the RadMap for our purposes and if so how?
