How to: Display multiple values within a single series

We are looking to replicate your Silverlight example using WinForms.RadChartView. We need to be able to display multiple sections (represented by a color) within each bar (in your example - a country)

In addition @ run time we need to be able to ...

Drop new values onto a specific bar (country) and repopulate the chart to include the new value(s)
Drag an item (represented by a color) from one bar (country) to another and repopulate the chart to include the new value(s) or remove it altogether.

Is this possible in WinForms.RadChartView?
- If yes, can you provide/point us to an example?
- If not what are our options?

Enum changes not applied when losing focus

When a property based on an enum is changed, the change is not applied unless you hit ENTER or click elsewhere on the property grid. This issue can be demonstrated by the PropertyGrid->Setttings demo. Change the “AccessibleName” property and then click on the “UI Settings” groupbox so the property grid loses focus and you can see the property get applied. Do the same thing with “AccessibleRole” and the change is not applied until you click back on the property grid.

PDFViewer partial show PDF

Hello,

I use PDFViewer in a VB.NET 4.0 Winform project, with Telerik version 2013.2.724.40.

When the PDF have just an image, it's ok. But when the PDF have a background image and text in front of, it's not working (just display background image). I try to load the PDF with your silverlight demo, and it work fine.

My code is :
Dim mStream As New MemoryStream()
mStream.Write(tdo.Document, 0, tdo.Document.Length)
radPdfViewer.LoadDocument(mStream)
radPdfViewer.ScaleFactor = 0.6F

I try to save the PDF file in a directory to send to the LoadDocument method's, but the result is identical. When I open whith PDFReader, it's OK.

Thank for your help

RadGridView ComboBox source of data

Hi!

I have a RadGridView with ComboBox column, Whole Grid is binded to DataTable.
In comboboxes I would like to have options like: "MS Access", "MS Excel", and a few more. These are options user can choose, and these options are not in DataTable from beginning. How can I populate binded ComboBox with different values than from DataTable?

Thanks in advance!

Setting CommandBarToggleButton ToggleState with Default Theme

I have noticed a strange behaviour with togglebuttons when using the default theme, which seems to not occur in the other themes I have tested.

When the CommandBar toggle buttons are activated using a mouse the pressed state has the gradient, when I set them programatically, or when I change to another theme in code and then change back to Default theme the buttons are still depressed but they are now a solid shade of orange and have lost the gradient. This behaviour doesn't seem to occur on any of the other themes.

In the image I have set 5 of the 6 buttons to toggled, taken a pic1 in black theme, changed to default theme where it loses the shading pic2, then used the mouse to togggle off and on two buttons which are now again shaded pic3.

Best Regards,

Kurt

custom cell replicates on scrolling radgridview

i implemented custom cell as per samples of telerik. the custom cell is being assigned to specific cells only of the column istead of the entire column. for example one cell is a normal textbox while another implements customdropdownlist or customradbutton in the same column. i am creating the custom cells in createcell event where i check for specific conditions to determine where to change cell type to be customdropdownlist.
here is part of the code that does this:

If e.Column.Name = "colResult" Then

If e.Row.RowInfo.Index > -1 Then

Dim dataItem As GetLastTestResultResult = DirectCast(e.Row.RowInfo.DataBoundItem, GetLastTestResultResult)

Dim term? As Integer = dataItem.TCount

If term.HasValue AndAlso term > 0 Then

Dim elem As New CustomDropdownCellElement(e.Column, e.Row)

elem.SetComboboxValue(CInt(dataItem.Result))

e.CellType = GetType(CustomDropdownCellElement)

e.CellElement = elem

end if

the problem is that when scrolling vertically the radgridview, the custom cells move from their row to other rows on the same column. i am not able to find a solution.
