I would remove the RadGridView scrollbars, I will use the RadDataPager to display only the amount of items that fit on the screen. But is not working. Any idea how to proceed? Sorry for my bad English.

My Code:



Here I do the calculation:


Thank you!

I would like to add a image in Raddocument  behind table. 
How can I do this?

I'm programmatically generating LegendItems for a RadLegend object, but the labels for the legend all seem to be partially transparent or grayed out or something. I can't find any properties to change this, and it doesn't seem like default behavior since the documentation doesn't show anything like this.

Hi. I'm trying to figure out how to locate modify the attributes of a Hyperlink (e.g. NavigateUri) after it's been created. What's puzzling me is that it seems that you can create a HyperlinkInfo object and then insert it into the document, but there doesn't seem to be any way to get a HyperlinkInfo object back from the document. When I import my document from RTF and then save as xaml, I got the following results (at bottom.)

I know that there are ways to pull back start tags, inlines, and so forth, but none of those seem to correspond to an actual HyperlinkInfo object. Furthermore, I'm seeing two different kinds of Hyperlink information (one in the <FieldRangeStart...>xxxx</FieldRangeStart...> pair, and another in the <HyperlinkRangeStart...>xxxx</HyperlinkRangeStart> pair. It's not clear where I should make mods.

Also: In your InsertHyperlink demo, if I insert a Hyperlink and then come back to edit it, then in module InsertHyperlinkDialog.xaml.cs, the ShowDialog procedure on line 74 includes a parameter for "CurrentHyperLinkInfo as HyperlinkInfo". Indeed, if I break at that point, the information is there, having apparently been supplied by the editor. However, I cannot figure out how to get the same info independent of the editor.

Please explain how this all works. The xaml snippet I promised is as follows:

<t:FieldRangeStart AnnotationID="558">
       <t:HyperlinkField DateTimeFormatting="" DisplayMode="Result" GeneralFormatting="" LocationInFile="" NavigateUri="hypercase:///cite_000031"
NumericFormatting="" Target="" />
</t:FieldRangeStart>
<t:HyperlinkRangeStart AnnotationID="559">
    <t:HyperlinkInfo NavigateUri="hypercase:///cite_000031" />
</t:HyperlinkRangeStart>
    <t:Span FontSize="16" FontStyle="Italic" StyleName="Hyperlink" Text="Ass’n of Am. Physicians and Surgeons Inc. v. Clinton" />
    <t:Span FontSize="16" StyleName="Hyperlink" Text=", 997 F.2d 898, 909 (D.C. Cir. 1993)" />
<t:HyperlinkRangeEnd AnnotationID="559" />
<t:FieldRangeEnd AnnotationID="558" />



 

A two way binding to selected item is not applying the "Selected" (in this case "Pressed") template to the timeline item.

Surely expected behaviour would be the same as that of a Gridview or Listview, that is, setting the SelectedItem/s in the view model should result in the same appearance as if the user had actually clicked the timeline item with the SelectionMode set to single?

Hi,

I have strange tab navigation here:

When
   - the first cell in grid is current and the user presses <Shift>+<Tab> the GridView is focused
   - if the last cell in grid is current and the user presses <Tab> the GridView is focused

Normally I would expect that the first focusable element before the GridView or after the GridView is focused, but not the GridView itself. I would like to hide the focus visual on the GridView, but if the GridView is focused, the user looses orientation without a focus visual.

I have tried to make the GridView Focusable="false". This does not work, because the implementation expects the GridView to be focusable. Otherwise other things do not work.

What seems to be strange is that the GirdView moves the focus correctly in the first place but afterwards a second tab navigation routine is executed in the .NET core, that moves the focus again to the GridView. It seems that the KeyDown event is not marked as Handled in these cases and the focus moves twice. Is this behavior caused on our side or is it a bug? Thx.

Hi,

I am using version 2014.1.0310.40

I create a map with 3 layers, all of which inherit from VisualizationLayer.  Sometimes when I delete one of these layers, I get the following exception

Hello All,

I want to implement Cut, Copy and Paste feature for the Mind Map demo available in Telerik UI for WPF. So suppose I want to copy a node and its attached sub-children and paste it as children of another node.

Kindly help that how can I do this if I want to extend the Mind Map sample with this feature. 

Hi!

I have two problems but they are the same:

In my scenario I have a raddiagram and, in a moment of my application, I have show the diagram and to do zoom. If I put Diagram.IsEnabled = false, zoom doesn't works. In the other way, I put other attributes (resizing, draggin,...) at false, the zoom works correctly, but Diagram obtains the focus (I put Focusable = false) and I don't want this case, because I need to have the focus in another place of the window.

Exists the other way for to do this scenario?

Maite.

Hello,
I followed your code for DiagramToolBox in Telerik Demo (please, check the attached image).
But the Cell Size doesn't work! Even I can see the initial value (20,20).
I tried Debug it, It wasn't hitting the setter in the property at all!

I added 
UpdateSourceTrigger=PropertyChanged and Converter={StaticResource DoubleToStringConverter}} to TextBox line. I thought I would need them. But it didn't work!

How it is working in the Demo without a converter ?

Thank you.
