I have the TabControl with any TabPages. Each page has TreeView with with several thousand nodes + DataPager. All TabPages have identical XAML and ViewModel. An exception occurs when I switch between pages (incorrect arguments RadDataPager.PageSize and RadDataPager.PageIndex). If  TreeView on selecting TabPage is empty exeption not occurs.

Fragment my XAML :

Is it possible to change the behavior of the checkboxes inside RadPivotFieldList so that the first underscore of the label is visible? I cannot find a way without retemplating the whole control. The text actually is UID_BNK - bank code, but the underscore is swallowed by the checkbox.

Kind regards,

I'm getting an error dialog opening SDK Samples Browser:

Cannot connect to Telerik XAML-SDK GitBug repository. Possible reasongs:

- internet connection is not available

- GitHub.com is down for maintenance

Both assumptions are false.

How to fix this annoying dialog?

Hello,

Look at the screen shot: the first entry is selected by the search, but it is not highlighted. It's because the "i" char has a special accent on it.

It seems that the logic between search and highlighting is not the same.

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}">

Hi

How can I create a custom Hexagons RadButton with material style and effect?

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

Hi,

Facing an strange issue, whenever i am trying to add a new row in the grid , the multi select filters starts showing empty value in the filter options, so from which event i can rectify this issue.

Help is appreciated. Attached the screenshot.

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!
