Chartview Trackball text format

Hi,

I'm currently working with implementing new chartview in winform application.
I activate the trackball to show informations like in this sample
http://www.telerik.com/help/winforms/chartview-features-trackball.html

In this sample, informations are displayed in color, each on a new line and with the LineSeries name.

X - 3: 23
Y - 3: 7

But when I copy the same code in my solution, I view
"X 23 Y 7"

Is there an option to set the default text format ?
If not, do you have sample for using TextNeeded event to build this text formated with axes information ?

Thanks

[Solved] Underline issue with Tables and PDF Export

Hi,

I've run into an issue with underlining a text span that is in a table cell. When I create the content of the cell by doing the following:

row = New TableRow

cell = New TableCell()

p = New Paragraph()

sp = New Span()

sp.Text = "Benefit Start"

sp.UnderlineType = UI.UnderlineType.Line

p.Inlines.Add(sp)

row.Cells.Add(cell)

table.Rows.Add(row)

The underline extends past the final character. See the attached 'underlineissue_richtextbox.jpg' for an example, this jpg also shows the same text/paragraph added to the section outside of a table and it works fine.

The problem is even worse when I export the document to a PDF as all the underlines are too wide. See the second attachment for an example.

Is there a work around for this issue or am I doing something wrong?

Optimizing GridViewComboBoxColumn

Hi,

I have a RadGridView that has a GridViewComboBoxColumn containing 40,000+ values through data binding. Viewing the combobox values in every cell under that column is taking a few seconds. I think the reason for this sluggishness is because it loads up the values only when a cell is clicked. So I'm wondering if there's any way to optimize this behavior.

Thanks!

DateTimePicker Canceling the ValueChanging Event

Hi,

I have a form that allows the user to change from and to date.
But if the user changes the "to date" to an illegal date (defined by the database) the user will get an message where he can override this error or not. If hi does not override it, i want the date to be reset (cancel the valuechanging) event.
But the value in the datetimepicker stays at the date selected by the user regardless of me doing cancel = true or not.

How can i achieve this functionality without triggering the change event once again?

Regards

Editting Minimize/Maximize/Close Buttons

I have been able to modify the other aspects of the Title Bar using the Visual Style Builder, but I cannot find the properties/elements/source files to change the appearance of the Minimize/Maximize/Close buttons. How do I alter these? The attached image shows how the default ones are a mismatch with the visual style I am trying to create.
