Hi.

I tried to print out the chart.
I created some codes with reference to the source code of demo project(Export PDF/Print), but following exception has occurred.

I've tried to save docx file. It worked fine. please check my codes......

----------------------------------------------------------------------------------------------------------------------------------------------

private void PrintChart()
{
RadRichTextBox RadRichTextBox1 = new RadRichTextBox();
RadRichTextBox1.Document = CreateDocument();

// below line made a exception : NullReferenceException was unhandled
RadRichTextBox1.Print("test",PrintMode.Native);

}

private void CreateChartDocumentPart(RadDocument document)
{
Telerik.Windows.Documents.Model.Section section = new Telerik.Windows.Documents.Model.Section();
Telerik.Windows.Documents.Model.Paragraph paragraph = new Telerik.Windows.Documents.Model.Paragraph();

MemoryStream ms = new MemoryStream();
currentChart.ExportToImage(ms, new PngBitmapEncoder());

double imageWidth = currentChart.ActualWidth;
double imageHeight = currentChart.ActualHeight;
if (imageWidth > 625)
{
imageWidth = 625;
imageHeight = currentChart.ActualHeight * imageWidth / currentChart.ActualWidth;
}

ImageInline image = new ImageInline(ms, new Size(imageWidth, imageHeight), "png");

paragraph.Inlines.Add(image);
section.Blocks.Add(paragraph);
document.Sections.Add(section);

ms.Close();
}

private RadDocument CreateDocument()
{
RadDocument document = new RadDocument();

Remove border around the RadGridView ChildTableDefinition

Hello Telerik Team,

Is it possible to remove the border around the ChildTableDefinition?

See attached image where I have marked the border using red rectangles. Note that I want to remove the border completely on all sides of the child grid

Thanks,

[Solved] Drag and Drop Between Two TileViews

Hi everyone,

A simple question - but I'm not sure it's a simple answer :) ...

Is there a straight forward way to enable tiles to be dragged (copied or moved) between two or more instances of a TileView?

I'm developing an audio performance app that allows the user to create multiple playlists (each playlist being a viewmodel/view in a collection). I'm using the TileView to display the 'tracks' in the playlist, as it has the right combination of selection, click n' drag and re-ordering animations that I was looking for - but in addition to dragging tracks (tiles) around to reorder them in a playlist (tileview), I'd also like to be able to drag them across into other playlists (additional tileviews).

Any thoughts?

Thanks!

Oli.

Required Assembly is Missing

After I publish a WPF application and then try to install it . . . I get the following error:

Unable to install or run the application. The application requires that assembly Telerik.Windows.Data Version 2010.2.924.40 be installed in the Global Assembly Cache (GAC) first.

I am using Version 2010.3.1314.40 . . . so I am not sure why an earlier version is required. In the properties of Telerik.Windows.Data,
Copy Local is set to true. So if this copies the assembly to the client machine that I assume this should resolve the issue, but it has not.

I have attached an image of the full properties of Telerik.Windows.Data.

Please help if you have any ideas.

Thanks.

[Solved] How many data series I have in a RadChart ?

Hi,

I want to disable some buttons when I have more that one dataseries in the chart. So I have chosen DataBound event of chart. But I can not access to number of dataseries which was loaded into grid at that moment. I have seen number of data series in some private properties of chart by using Quick Watch window but I can not see in public ones (number of data series).

Thanks in advance.
