Hi,

I would like to know, if it is possible to fit to a type of "box"-Coordinates inside the PDF-Files

I would like to open a pdf and then define the "View" to display.

Could be 4 Points (Left upper/Right upper/Right lower/Left lower) or (Left upper + Width/Height) or something similiar.

Then the PDF-Viewer should scroll to the left upper point and zoom to have the "box" displayed.

Is this possible?

Thanks

Hello,

I have a RadcomboBox with Multiple Selection allowed. The ItemSource of this combo is a enum.

 public enum WorkStatus   {

        [Description("WORKING")]
        Working,
        [Description("NOT WORKING")]
        Not_Working,
        [Description("WORKING WITH ERRORS")]
        Working_with_errors,
        [Description("STOPPED")]
        Stopped
    }

And this is my code:

<Window x:Class="MultiSelectComboboxEnums.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:local="clr-namespace:MultiSelectComboboxEnums"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        Title="MainWindow"
        Height="350"
        Width="525">

    <Window.Resources>
        <ObjectDataProvider x:Key="statesWork"
                            MethodName="GetValues"
                            ObjectType="{x:Type sys:Enum}">
            <ObjectDataProvider.MethodParameters>
                <x:Type TypeName="local:WorkStatus" />
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>

        <local:EnumToFriendlyNameConverter x:Key="enumToFriendlyNameConverter" />
    </Window.Resources>

    <Grid>
        <telerik:RadComboBox Width="350"
                             Height="26"
                             Margin="20"
                             HorizontalAlignment="Center"
                             VerticalAlignment="Center"
                             telerik:StyleManager.Theme="Windows8"
                             ItemsSource="{Binding Source={StaticResource statesWork}}"
                             ClearSelectionButtonVisibility="Visible"
                             IsSynchronizedWithCurrentItem="False"
                             AllowMultipleSelection="True"
                             MultipleSelectionSeparator="|"
                             MultipleSelectionSeparatorStringFormat="{} {0} ">
            <telerik:RadComboBox.ItemTemplate>
                <DataTemplate>
                    <Label Height="Auto"
                           Margin="0"
                           VerticalAlignment="Center"
                           Content="{Binding Path=., Mode=OneWay, Converter={StaticResource enumToFriendlyNameConverter}}" />
                </DataTemplate>
            </telerik:RadComboBox.ItemTemplate>
        </telerik:RadComboBox>
    </Grid>
</Window>

In dropdown item I can see the correct name using a converter but how can I do to see the same in the selected items box?

I attached two images showing this error.

Thanks in advance.

Hi.

I'm considering the purchase of UI for WPF, so I downloaded to test the trial version.

I'm working through this example (http://docs.telerik.com/devtools/wpf/controls/raddataservicedatasource/getting-started/creating-the-data-bound-controls), but instead of WCF services, I'm using OData version 7.

Everything works fine, except when I'm trying to apply even a single filter on columns containing enum elements, I'm getting this exception :

Hi,

I need to attach my project how should i attach it was a .Zip file.

I am having an issue in RadTabItem with ContentControl which hides the DockPanel.

If you run the attached project you may see the PresetTitle Dockpanel in the right hand side of the window and mouse over to the PresetTitle Content(Don't pin the dock panel)you may see 3 Tab's underneath(Preset,group,SiteSee) that and select all the 3 Tab's one by one continuously for 3 or more times and it automatically hide the PresetTitle dockpanel that should not happen.

If i have not use the ContentControl it works fine.

Please check in the project that Goto TestUserControl.xaml uncomment the line from 32 to 37 and comment the line 38 and run the application  it is working as expected.

My scenario is i need to use the contentControl inside the Tab Control.

Please check and let me know what i am doing wrong.

Thanks In Advance :)

I have a Telerik Treeview on a Telerik Docking RadPane. If the pane is unpinned, so the user no longer can see the tree, a call to GetItemByPath returns null.

I give the user an option to pin the pane, and navigate the tree, or unpin the pane, and click "Next" and "Previous" buttons to navigate the tree. If the pane is pinned and the tree is visible, GetItemByPath returns the RadTreeViewItem. If the tree is hidden, GetItemByPath returns null.

If I expand all nodes on the tree first, GetItemByPath returns the RadTreeViewItem even when the tree is hidden. I have IsVirtualizing set to false.

Is there a way to set the SelectedItem using GetItemByPath when the tree is not visible? Or is there another call I can make?

Thanks,

Scott

I'm using a CellStyleSelector to switch the style based on some properties of the model bound to the row

When I'm persisting the layout i need to save those style (Background and Foreground color) on two properties of my Columnproxy.

Before using the CellStyleSelector I was getting the column.CellStyle but now I got a null on that property and I'm unable to retrieve the current cell style.

Is it possible or since it's done on the fly I cannot have it?

Thanks

Hi,

i creat a diagram with the radDiagram Control, saving it as xml-file, workin fine! It is possible to find all
Elements in the Diagram with c#, so i can wirte my own xml-file?

Thanks
Best Regards
RENE

Hello,

Our company developer team is trying your product and we are wondering if its possible to set the Width and Height of the Diagram, we tried all the examples in the documentation from viewport to set a container in the center of the diagram and use it as a diagram, we used services, dragging area restrictions but non of then are working as expected.

Our main goal is the following:

We have a grid with 2 Rows (1 for buttons/ the other one for the diagram), out clients need to be able to set the area of the diagram that in the future will export the elements that are inside it. 

We tried to set the height and witdth of the diagram and also the size of the viewport,however, the result is just a smaller view of the diagram but not a real smaller page.

Would you be able to help us?

As commented before we tried to implement the examples from Github, forum and documentation without success.

We will wait for your answer, thanks.
