Is there a way to load this RadFixedDocument into a RadPdfViewer without writing the document to a file first and then loading it in the viewer?
Workaround:
You can achieve the desired functionality by exporting the RadFixedDocument to a MemoryStream instead of a file in the file system and then load it in the PdfViewer:
RadFixedDocument document = CreateRadFixedDocument();
PdfFormatProvider pdfFormatProvider = new PdfFormatProvider();
Stream ms = new MemoryStream();
pdfFormatProvider.Export(document, ms);
radPdfViewer1.LoadDocument(ms);
Add heatmap control as in the WPF suite http://www.telerik.com/products/wpf/heatmap.aspx
According to PDF format specification, there are three valid encoding name values (MacRomanEncoding, MacExpertEncoding and WinAnsiEncoding). There are documents that instead of skipping the optional Encoding property, are writing invalid /NULL name value in the font dictionary. Currently, in this invalid document scenario RadPdfViewer throws and catches Exception and this results in missing text content. We may handle this invalid document scenario by ignoring the invalid Encoding value.
Our clients can download different product files from their Telerik account:

Currently, when Digitally Signed Assemblies are necessary, they submit support tickets and the support engineers provide the signed assemblies. It would be nice to be directly uploaded to the Telerik account like the rest of the product files.

This is about this method:
public void SetError(GridViewCellCancelEventArgs e, Exception exception)
{
GridViewDataErrorEventArgs args = new GridViewDataErrorEventArgs(exception, 0, 0, GridViewDataErrorContexts.Commit);
if (e != null)
{
args = new GridViewDataErrorEventArgs(exception, e.ColumnIndex, e.RowIndex, GridViewDataErrorContexts.Commit);
}
this.EventDispatcher.RaiseEvent<GridViewDataErrorEventArgs>(EventDispatcher.DataError, this, args);
if (args.ThrowException)
{
throw args.Exception;
}
if (args.Cancel)
{
//TODO: cancel row edit
}
}The method GridViewTemplate.SetError accepts a parameter of type GridViewCellCancelEventArgs (named e), but uses the information to create a new object of type GridViewDataErrorEventArgs (named args) and uses information from e to fill args.
The method then fires an event with args. Args also has a property Cancel which can be set in the event handlers. But nothing is done with that property.
Parameter e also has a property Cancel which is never be filled. So it could be useful, at the end of SetError, to set e.Cancel with args.Cancel. This way the caller can use the Cancel information from the events.
This request is also related to my next request.
PS: Why is GridViewCellCancelEventArgs called this way? It implies it has arguments for an event, but it is not used for an event, am I right?
We want to sort a column (the cards in specific Column) in a RadTaskboard. It would be good to have the possibility to use a custom comparer as well
Add a possibility to set the auto-expand delay on drag-drop in RadTreeView.
The assembly is required for our RadMarkupEditor using the IE rendering engine. It allows you to specify HTML-like text formatting at design time in the Properties window of Visual studio:
When you use var, object is assumed. Of course, the object contains a GridViewCellInfo, but you have to cast it first to use one of its members.
The goal is to prevent unnecessary casts.
The ChartLegendElement displays the legend items in a StackLayoutElement which can be either vertical or horizontal.
public RadForm1()
{
InitializeComponent();
Random rand = new Random();
List<LineSeries> list = new List<LineSeries>();
for (var index = 1; index <= 15; index++)
{
LineSeries ls = new LineSeries();
ls.LegendTitle = "Series " + index;
list.Add(ls);
}
for (int index = 1; index <= 100; index++)
{
foreach (LineSeries s in list)
s.DataPoints.Add(new CategoricalDataPoint(index, rand.Next(0, rand.Next(5, 20))));
}
this.radChartView1.Series.AddRange(list.ToArray());
this.radChartView1.ShowLegend = true;
this.radChartView1.ChartElement.LegendPosition = LegendPosition.Bottom;
this.radChartView1.ChartElement.LegendElement.StackElement.Orientation = Orientation.Vertical;
}Horizontal:
Vertical:
It would be good to provide an option for wrapping the legend items:
Workaround: use an appropriate container for the legend items to wrap the legend item and use the space more efficiently

This is about the following method:
public void SetError(GridViewCellCancelEventArgs e, Exception exception)
{
GridViewDataErrorEventArgs args = new GridViewDataErrorEventArgs(exception, 0, 0, GridViewDataErrorContexts.Commit);
if (e != null)
{
args = new GridViewDataErrorEventArgs(exception, e.ColumnIndex, e.RowIndex, GridViewDataErrorContexts.Commit);
}
this.EventDispatcher.RaiseEvent<GridViewDataErrorEventArgs>(EventDispatcher.DataError, this, args);
if (args.ThrowException)
{
throw args.Exception;
}
if (args.Cancel)
{
//TODO: cancel row edit
}
}Right now, the method GridViewTemplate.SetError accepts a parameter of type GridViewCellCancelEventArgs, which in itself is weird, because event args should only be used inside events and OnXXX-methods. But since SetError fires an event, one could argue that this method is like a OnXXX-method.
But inside it becomes more weird, it translates GridViewCellCancelEventArgs into GridViewDataErrorEventArgs. And I must admit, the last DataError-args feel a lot more logical that CellCancel-args when firing setting an error. Furthermore, if I create an override of class GridViewCellCancelEventArgs to contain more data about an error, this information never reaches the event handlers.
So why this translation? Or better: Why this parameter?
My suggestion would be to make a new overload:
public void SetError(GridViewDataErrorEventArgs e)
{
if (e == null)
throw new ArgumentNullException(nameof(e));
this.EventDispatcher.RaiseEvent<GridViewDataErrorEventArgs>(EventDispatcher.DataError, this, args);
if (args.ThrowException)
throw args.Exception;
if (args.Cancel)
{
// TODO: I really do not know what telerik wanted to do here, so I live this up to Telerik.
}
}
Class GridViewCellInfoCollection does not implement any generic interfaces.
