Hi,

Thanks in advance.

Hi Telerik Team,

I have a sheet and should print it directly in default printer. I'm using RadSpreadsheet, but does is not working.  I follow the documentation shown: http://www.telerik.com/help/wpf/radspreadsheet-overview.html. Basicly, I do:

PS: I'm evaluating the components for a new project (The trial version).

Thanks.

Hello,

I have a trouble Saving a resource dictionary which uses Telerik.Windows.Controls assembly. Telerik.Windows.Controls.

The exception thrown:

An unhandled exception of type 'System.NotSupportedException' occurred in System.dll

Additional information: 'Office2013ResourceKeyTypeConverter' is unable to convert 'Telerik.Windows.Controls.Office2013ResourceKey' to 'System.Windows.Markup.MarkupExtension'.

Part of xaml that's causing the problem:

<Grid>
                <Path
                    Stretch="Fill"
                    Fill="{telerik1:Office2013Resource ResourceKey=ValidationBrush}"
                    HorizontalAlignment="Left"
                    VerticalAlignment="Top"
                    SnapsToDevicePixels="True"/>
                <Border Background="{telerik1:Office2013Resource ResourceKey=ValidationBrush}" Margin="5 0 0 0" Padding="1">
                    <ContentPresenter
                        Content="{Binding Error}"
                        TextBlock.Foreground="{telerik1:Office2013Resource ResourceKey=MainBrush}"
                        Margin="4 2"
                        TextBlock.FontSize="15"
                         />
                </Border>
            </Grid>
            <ContentControl/>
        </Grid>

and namespace mapping:

xmlns:telerik1="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"

I load this resource dictionary with

var myDict = Application.LoadComponent(new Uri(packUri, UriKind.Relative)) as ResourceDictionary;

and then try to save it with:

System.Windows.Markup.XamlWriter.Save(myDict);

And that's when the exception is thrown.

Compiler tooltip: "Local property 'ResourceKey' can only be applied to types that are derived from ThemeResourceExtension`1"

I've checked it, and Office2013ResourceExtension derives from ThemeResourceExtension`1.

What might be the problem here?

i want to use a radAutocompletebox in my application. the ItemSource is dynamically from my database. i have a code like this: var list = extrainfo.database.UserPrivateInfoes;
foreach (var item in list)
{
obs.Add( new RadAutoCompleteBoxItem{Content= item.UName} );
}
TX_Receiver.ItemsSource = obs;which the obs is observablecollection .the problem is when the items are shown in dropdown i have an item with TWO CROSS BUTTON for remove. actually it is not nice enough!! but when i add a list of String to ItemSource the problem is resolved. i need to have an item not just with a string for its name, i need more info (like UID) for every item. is there any solution??

Hi!

I Have a GridView loaded with 2000 records, grouped by one column and paginated using the RadDataPager.

To make the grouping and pagination work, i needed to use a PagingBeforeGroupingQueryableCollectionView. With a standard Collection the paging was not working correctly as it counts the groups per page and not total items per page:

Now, i need to add Hierarchical data, so i defined a ChildTableDefinitions. In the DataLoading event of GridView it detects correctly the parentrows and allows me to define the columns for the child gridview, even in the row loaded event i can check what rows have childs to show the expandable buttons on them. All this works pretty well but when i expand one row with childs, the child gridview is showed without data. If i remove the grouping column and the child data is in the same page as the parent row, i can see the child rows. If the child rows are in another page, i can't see them. If i remove both grouping and paging, all works perfectly, showing the child data for every parent row. But as soon as i group the data again, even without pagination, the child gridview don't show any data.

Is there a way we can have Grouping, paging and child data working in the same GridView, independently of the page of the data?

 Kind regards,

Hi,

I'm trying to fit a TreeView into a Combobox. There are already many threads which all refer to this blog post:

http://blogs.telerik.com/xamlteam/posts/10-05-12/treeview-in-combobox-with-radcontrols-for-silverlight-or-wpf-final-take.aspx

Unfortunately, the example is not working (anymore?) in WPF.

There seems to be a problem with the converter. In Silverlight, everything works fine, in WPF however, the converter is called, even when you open the DropDown (which does not happen in Silverlight). In this converter call, the "return false" condition is triggered and so the popup never opens. 

Can you provide a new sample on how to fit a TreeView into a ComboBox (or DropDownButton)?

Best regards 

 

The docs for some rad controls have a nice page listing the default shortcut keys supported by a given control.  For instance, the RadRichTextBox control has this page:

http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/features-keyboard-support.html

However, I can't seem to find a similar page for RadGridView.  So, two questions:

1. What standard shortcuts are supported "out-of-the-box" by RadGridView?
2. Is there a page similar to the above-mentioned RadRichTextBox page that documents these keys?

Thanks.​

Hello Everbody, 

I have the following question.

I have this Windows Form Application in C#.

What it does is you input a string in a textBox then you click on a button and it performs some edits on the string you have entered and it outputs it to another textbox. Till here everything is fine but I would like to have a listBox where I can have a rule like extract first name and it will parse the string look for the first name based on some internal rules and extract it then it will output only the first name, because only that rule was selected from the listBox and no other output. If I select first name rule from the listbox and also select last name rule from the list box it will execute both rules on the inputted text and output it in the output textbox.What can you suggest I can do for it?Any help will be appreciated.

Regards,

Ilia
