Hi,

I'm creating a chart that is based off the MeteoChart example. Specifically, I'm using the same concepts as the SplineLabelStyle in the MeteoChart to display custom icons overriding the default item label.

The MeteoChart has the following XAML to style the SeriesItemLabel with a custom control template that contains custom icons:

What I'd like to do is add a tooltip to this image to display more information, ie:

The problem is that the above XAML doesn't work. While the example runs, tooltips are not displayed when hovering over the icon. I've tried shifting the tooltip to the canvas instead and even tried displaying fixed text as the tooltip, however none of these alternatives get tooltips to display.

I would like to display the tooltip on the customized item label because:

1. these labels are easier targets to hover over instead of point marks,
2. the labels are displayed in a different location to the point mark, and finally
3. I'm actually hiding the point mark in my actual scenario (I'm just displaying the icons).

How can I define tooltips for custom item labels?

Alternatively, how can I customize the PointMarkItemStyle to display custom icons (and then I can use the default item tooltip provided).

Kind regards,
Dave.

I am doing a search/replace in code using the RadDocument and I am getting a strange null error.

Here is the code:

doc.Selection.Clear();

            DocumentTextSearch search = new DocumentTextSearch(doc);

            var rangesTrackingDocumentChanges = new List<TextRange>();

            var resultRanges = search.FindAll(searchText);

 

            foreach (var textRange in resultRanges)

            {

                TextRange newRange = new TextRange(new DocumentPosition(textRange.StartPosition, true), new DocumentPosition(textRange.EndPosition, true));

                rangesTrackingDocumentChanges.Add(newRange);

            }

 

            foreach (var textRange in rangesTrackingDocumentChanges)

            {

                doc.CaretPosition.MoveToPosition(textRange.StartPosition);

                doc.DeleteRange(textRange.StartPosition, textRange.EndPosition);

                doc.Insert(mergeText, new Telerik.Windows.Documents.Model.Styles.StyleDefinition());

                textRange.StartPosition.Dispose();

                textRange.EndPosition.Dispose();

            }

When the RadDocument is simple,this works fine, however, when I put the Merge fields in Tables, it is throwing an error on the search.FindAll() method:

System.NullReferenceException: Object reference not set to an instance of an object.

Hello,

I'm looking to stack a chart on top of an existing chart, that scrolls along the same timeline as the bottom chart.  Something like this:

Good afternoon,

I'm having an issue with RadComboBox binding. I'm implementing iNotifyPropertyChanged which works with both get and set properties.
When I change my selection in the RadComboBox the propertychanged event is raised and works fine.
However, I have IsEditable="True" & IsReadOnly="True" set


When I delete all of the text in the ComboBox using the keyboard "back space" key the property changed event isn't raised.
i.e. I would expect the selected index to be -1 again and the selected value to clear to some default.

Any idea how I can get around this?

This problem came to light because my DataErrorValidationRule isn't working properly if the selected ComboBox text has been fully deleted after a selection was made.

When viewing the Validation Error in a message box it reads 'Value " could not be converted.'

Here's my validation code for your reference:




Thank you for your time,

Rob

I have a RadGridView that I am binding to a DataTable. The DataTable is dynamically generated in code. In the first column of the DataTable there is an object. I have an event attached to the RowLoaded event. In the RowLoaded event I want to set the template of the first cell to a Resource Template. This is the code I am using but the cell is always empty.

I have a form with some fields.  One of the fields is an ordinary TextBox that is bound to a variable of type Decimal.

When I type letters into the field, it's highlighted in red, to indicate that it has failed validation, but the validation error is not added to the form's ValidationSummary, and ValidationSummary.HasErrors remains True.

Am I simply misunderstanding what ValidationSummary is supposed to do?

I'm getting an application crash when I drag a row from a RadGridView and drop it into an open doc in WordPad.  I don't get a crash when I drop it into an open doc in Notepad, Word 2003, or Excel 2003.  Drag and drop within the application seems to work fine.

Exception:

• {"Error HRESULT E_FAIL has been returned from a call to a COM component."}
• -2147467259

Here's the stack trace:

We have an application that uses RadGridView.
We use RadGridView collection of objects that have attributes of validation.
There is also a button on the ToolBar that switches on edit mode of objects (editing is disabled by default).
The problem is that when you add a new object that does not pass validation and disable the editing mode, the application crashes with StackOverflowException.
If the button Edit Mode is not on the ToolBar everything works fine.

List the steps to repeat this behavior:
1) Press the Edit Mode (on the toolbar)
2) Add a new blank line (by pressing Ins)
3) Cancel the edit mode by clicking the Edit Mode (on the toolbar)
4) Click on any item on the main window
5) get the exception

If in p.3) you press the the EditMode button not on the toolbar everything will work fine without any exceptions.

Hello,

I'm  having a tough time getting a List box to Drag and Drop onto a RadDataForm

the RadListBox has a different type object bound to the collection than the RadDataForm , however both share a single common field

any examples would be greatly appreciated i have included a snapshot of the application along with the offending issue
