Good afternoon,

We started getting this exception on one of our forms, after upgrading Telerik control for WPF to a new version.
The exception occurs for a DataGridHyperlinkColumn of the DataGrid in the RadTabControl.
Can anyone help us with this?

Stack trace:

I've not been able to locate any information regarding this request, so the question is asked here!

I want to change the automatic layout of the tiles from Left to Right, Top to Bottom  to Top to bottom , Left to Right.

i.e. change from 

1,2,3,4,5,6,7,8,9,10,
11,12,13,14,15,16,17,18,19,20,
21,22,23

to this
1, 6, 11, 16,21
2,7,12,17,22
3,8,13,18,23
4,9,14,19,
5,10,15,20,

where the numbers represent ordered tiles.

Is this  possible??

Regards,

Hello All,

I am trying to display an icon in the RadTabControl, right aligned, at the tab strip level.  I have done this with the RibbonBar using the TabStripAdditionalContent property, but in this particular view, I do not have a RibbonBar.  I was wondering if there is a similiar property I can use to achieve this, or using a style / template.

Any help is appreciated.

Thanks in advance

Hi,

I'm using VS2008 and Telerik V2012.1.326.35 and a special scenario occured when I'm trying to close a RadWindow.

In m'y application, I have a flag to detect any user data changes and when the user try to close the RadWindow, if the flag = true, I display a dialog to ask the user if he want to loose his changes or not. If he answer YES, no problem, the RadWindow close without any problem but if he answer NO, the previewclosed event are trigger a second time. The problem occur only when he click on my close button. If he use the upper right X button of the RadWindow, the normal behaviour are respected.

XAML CLOSE BUTTON:
---------------------------------
                <telerik:RadButton Margin="0 0 5 0" x:Name="btnClose" Click="btnQuit_Click" IsCancel="True">
                    <StackPanel Orientation="Horizontal">
                        <Image Margin="5 0 0 0" Source="Resources/Quit_32x32.png" Height="24" Width="24" />
                        <TextBlock Margin="5" VerticalAlignment="Center" Text="{StaticResource Quit}" />
                    </StackPanel>
                </telerik:RadButton>
CODE BEHIND
---------------------
        private void btnQuit_Click(object sender, RoutedEventArgs e)
        {
   try
   {               
    Close();
   }
   catch (Exception exc)
   {
    ClientUtilities.DisplayContextEventError(mTracingTool, exc, "BILDT019", "btnQuit_Click");
   }
        }

        private void Me_PreviewClosed(object sender, WindowPreviewClosedEventArgs e)
        {
   try
   {
                if (IsChangesInProgress && ClientUtilities.ConfirmDialog(this, LocGeneral.GetControlText("Confirmation"), LocGeneral.GetYesNo("CancelChanges")) != true)
                {
                    e.Cancel = true;
                }
                else
                {
                    DoAction(this, new ActionEventArgs(ActionEvent.Close));

                    // Apply persistence if required.
                    if (mUsePersistence)
                    {
                        string errMsg;
                        PersistenceStorage.Persist(PersistenceStorage.PersistenceAction.Save, this, "BillingModule.BillingDetails" + "." + this.IsReadOnly.ToString(), out errMsg);
                        mIsAlreadyLoaded = false;
                    }
                }
   }
   catch (Exception exc)
   {
    ClientUtilities.DisplayContextEventError(mTracingTool, exc, "BILDT019", "Me_PreviewClosed");
   }
        }

I receive this message when binding to a graphsource for each connection in the graphsource:
System.Windows.Data Error: 40 : BindingExpression path error: 'Content' property not found on 'object' ''SeqLink' (HashCode=58169988)'. BindingExpression:Path=Content; DataItem='SeqLink' (HashCode=58169988); target element is 'ContentPresenter' (Name=''); target property is 'Content' (type 'Object')

Commenting out all binding in the Style for connections in xaml does not help.


Have I done something wrong, is this a bug or is there something that I should be exposing through this property that would achieve some functionality that I fail to grasp? 

When I am scrolling through a large amount of data, there is a item that appears over the top of the grid that appears to show data from the first column in the grid.

What is this UI Element called?

Do you have any samples on how to style it.

Hello,
I'm currently evaluating the RadGridView (2012_1_326) and am encountering a problem setting the DisplayIndex.  The documentation (http://www.telerik.com/help/wpf/gridview-columns-reordering-columns.html) illustrates a simple scenario setting the DisplayIndex property in xaml.  When I implement this same example, i get a runtime ArgumentOutOfRangeException {"DisplayIndex out of range! Column2\r\nParameter name: displayIndex"}. 

My intent is to eventually bind this property to a custom object containing display settings which will be used to persist the user's preferences.

Your help is appreciated

Hi,

I've been working hard, with the help of telerik support, trying to extend the features of RadDocument. Please find my latest code sample download link here.

It took me quite some time to learn and make these features so this should help speed things up for you.

I have mainly be building up a library of custom annotation features, but there are also other additions.

Here are my methods:

• GetSelectedAnnotationsRangeStarts()
• GetPreviousAnnotationRangeStart()
• GetNextAnnotationRangeStart()
• GetNextAnnotationRangeStartAtPosition()
• GetSameLineNextAnnotationRangeStart()
• GetPreviousSameLineAnnotationRangeStart()
• IsCaretAtLineEnd()
• IsCaretAtLineStart()
• DeletedNonSelectedSpanTextAtCaret()
• DeleteOnlySelectedAnnotations()
• GetNextAnnotationMarker()
• GetPreviousAnnotationMarker()
• GetLastSelectedAnnotationMarker()
• GetPreviousAnnotationMarkerEndAndStartRanges()
• DeleteReadOnlyRanges()
• ToggleHighlightReadOnlyRangesOn()
• ToggleHighlightReadOnlyRangesOff()
• MakeReadOnlyRangesEditable()
• DeleteCurrentParagraph()
• IsCaretOnFirstLineInParagraph()
• IsPositionOnFirstLineInParagraph()

 

Feel free to let me know if you find any errors or more efficient ways to achieve the above.
Please upload your code if you extend the features of this code sample. Every little helps.

Rob

Greetings,

   I have used rad datagrid and it is working fine. But I have basically 1 problems that I felt very hard to implement.

1.  Using Custom Layout like in the blog
http://blogs.telerik.com/blogs/posts/09-02-03/how_to_use_custom_row_layouts_in_radgridview_for_wpf.aspx
but to start with I have strange error like
so I could not start to edit the example in the blog.  Can we edit the Values of rows that is inside the Custom row layout and also save it to the database also? Can the Custom layout hold other edit templetes like Combobox or masked text box in columns like Sex where there are only two option like male or female or in Phone number. Saving the edit on database also should be on focus. Because
dataContext.SubmitChanges();
was working fine on other project but under exactly same condition it is not working now.

If you want to go through my project here is a link of it.

Hi,

I'm using the RadMap to display KML data exported from Google Earth.  I've found that pushpins appear really large by default (about 64x64) and that it is the top left corner of the image that points to the location, and not the pin.  This looks ok when zoomed in, but it doesn't appear to point to the right location at all after you zoom out a little.

I'm loading in the elements using KmlReader.Read(Stream) and adding them to an InformationLayer.  Is this a known problem with either Google Earth or RadMap?

Thanks,

Kyle
