I'm trying to use the RadMaskedDateTimeInput control, using a mask of "g", which provides date and time input with the AM/PM indicator. The AM/PM indicator can be changed using the up/down arrows when SpinMode is enabled but there is no way to change the AM/PM value using the keyboard. Do you have any solution or it is impossible for this component to do this?

Thx in advance

Hi,

I have an issue with the RadGridView when used with NHibernate and Lazy loading.

When the page initially loads the gridview appears empty, but if I scroll data appears; this is aldo tru for paging with the RadDataPager, the first page appears empty but if you move to the second page then back, the data can be seen.

I am using the MVVM pattern and exposing an instance of VirtualQueryCollectionView to the view; if I put a break point on the property, I can see it being hit when the grid binds to the ViewModel. Looking inside the instance of the VirtualQueryCollection, I can see my data in the QueryableSourceCollection property, but the results view shows an IEnumerable filled with nulls.

A simplified view of my code would be something like:

View


ViewModel


Repository



Any advice would be more than welcome, however I am stuck with NHibernate and must use lazy loading because of the amount of data.

Thanks In advance.

Hello.

I'm using 'RadCartesianChart' as multi vertical axis.

I have problems.

'RadCartesianChart.HorizontalAxis' is used DateTimeContinuousAxis.

This is updated each 1sec. And other RadDataView is using 'LegendItems' of this chart.

Currently, graph of chart is changed.

But, MultiVertical & RadDataView is not updated data.

I want to update date about upper control.

What should I do?

If possible, please provide me about sample project.

Hello!

I found neither explanation in documentation nor sample about AutoInsertHyperlinks property.

How does it work?

For example:


RadRichTextBox show this as plain text.

What behaviour of AutoInsertHyperlinks property is standard?

And how I can use advantages of this property right?

Thank you.

I need that my Diagram makes zoom and it occupies all Grid where is stayed when I execute my application. I have saved the coordinates of shapes in a database, but these coordinates correspond to one type of screen, and if someone execute the application in an other screen to other size, I want that the Diagram makes zoom automatic to fill all screen. It's possible?

I am attempting to bind a GridViewComboBoxColumn's item source found in a child grid to a property in the data context of the parent row. I believe I need to use a relative source and find an ancestor; however, I am not sure what the ancestor type should be. I was hoping there was something similar to a ListBoxItem type but I have not found one.

Here is my Grid:

Here are my classes:


What I would like to see happen is when the user changes the ParentAttribute (through the Parent Attribute combo box column), the ItemsSource of the Parent Value column in the child grid will be bound to the ParentAttribute.Values field.

Hi,

I'm using the latest version of Telerik and I have a problem opening a PDF file. I created a USerControl which containe a RadPdfViewer and I am unable to load a document PDF file from disk.

Here is the piece of code I use to load my document:

            PdfDocumentSource doc = new PdfDocumentSource(new System.Uri(@"d:\document.pdf"));
            this.Viewer.Document = doc.Document;

The "doc.Document" are always null?!?

Thank's
Alain

Hi,

I have defined a custom tooltip for RadTreeView. Also I have used HierarchicalDataTemplate for my RadTreeView. Code is as shown below.

 <telerik:RadTreeView Margin="8" IsDragDropEnabled="True"  Name="CollExperimentTreeView"  SelectedItem="{Binding ActiveExp, Mode=TwoWay}"
     SelectionMode="Single" IsSingleExpandPath="False" IsLineEnabled="True"   VerticalAlignment="Stretch"
       temTemplate="{StaticResource TreeViewTemplate}"  ItemsSource ="{Binding TreeViewCollection,  Mode=TwoWay}" />

Custom tooltip and  HierarchicalDataTemplate  defined as below:

 <UserControl.Resources>
        <Style TargetType="{x:Type telerik:RadTreeViewItem}">
            <Setter Property="ToolTip" >
                <Setter.Value>
                    <ToolTip>
                        <ToolTip.Content>
                            <StackPanel Orientation="Vertical">
                                <StackPanel Orientation ="Horizontal">
                                    <TextBlock Text="Started:   " />
                                    <TextBlock Text="{Binding StartDate}" />
                                </StackPanel>
                                <StackPanel Orientation ="Horizontal">
                                    <TextBlock Text="Last Changed:   " />
                                    <TextBlock Text="{Binding LastAccess}" />
                                </StackPanel>
                                <TextBlock Text="{Binding Description}" />
                            </StackPanel>
                        </ToolTip.Content>
                    </ToolTip>
                </Setter.Value>
            </Setter>
        </Style>
        <HierarchicalDataTemplate x:Key="TreeViewTemplate" ItemsSource="{Binding Path=Experiments}">
            <TextBlock VerticalAlignment="Stretch" HorizontalAlignment="Stretch"  Text="{Binding Name}" />              
        </HierarchicalDataTemplate>
    </UserControl.Resources>

I do not want to display tooltip for those nodes that shows TextBlock containing Name,( HierarchicalDataTemplate )  

Please help

Thanks
