This is probably a basic WPF question, and not specifically Telerik related, but I figured I'd ask here. I am trying to create a reusable control, right now named SectionLayout, which allows the user of the control to define "sections", with Visuals in each section. I want to render this using RadTabControl.

Basically, the consumer of the SectionLayout would be using it like this:


I've already got most of it working. SectionLayout has a "Sections" property, of type SectionCollection, that holds items of type Section. Section has Name and Content properties. Name is a string, Content is an object.

The ControlTemplate for SectionLayout currently looks like this:


So, basically I'm just making an easier interface to use a RadTabControl. So I can reuse it in other places. Though it might change from being a RadTabControl to something else in the future.

The problem I'm having is getting the original DataContext of Section.Content property to flow into the RadTabControl.ContentTemplate. The ContentTemplate is of course given the business object (Section) as it's datacontext. So, I can easily present Section.Content. However, when I do so, Section.Content begins inheriting the DataContext given to it by the ContentPresenter, which happens to be Section.Content.

How can I do this properly? I want the user to be able to use my control as he would any normal layout control: Grid, Canvas, StackPanel, whatever. But, I need to use a TabControl internally to do the layout.

Just so you know, there are multiple errors here: http://www.telerik.com/help/wpf/radchartview-axes-datetimeaxes.html (XAML and VB).

Hi,

I'm using RadPivotGrid with Column Group:

            <pivot:LocalDataSourceProvider.ColumnGroupDescriptions>
                <pivot:PropertyGroupDescription PropertyName="Periodo" CustomName="Período" SortOrder="Descending" />
            </pivot:LocalDataSourceProvider.ColumnGroupDescriptions>
As the attachement image shows, I've put the total before column groups. It's a native control feature.

Now I want:

1 - That totals  cells have lines like group cells;
2 - Alternating backgroung color for group cells. Example: group A cells background diferent from group B cells background.

How can I achieve this?

Trying to bind to a collection of objects that encapsulate parameters:
these are read dynamically at runtime, and each parameter could be of a different type. The collection (array) is then contained in another class.
If i bind to an instance of the 'parent' class the parameter collection shows up via the colleciton editor ui, however, the values are not updated on edit.
Since we are not really interested in the parent object, I have tried binding to the collection directly, but then the only properties I get are the ones from the collection object itself, like Count.
What am I missing here, what do I need to define/override for the grid to work with these?
Pointers to example code would be excellent! :)

I have done grouping in the Telerik Gridview,My task is to Alter the header of the Group item at the run time , So i have implemented the below Code while clicking on the Expander i could able to get the content Nothing is displayed. 
Please help me on this

Howdy. I know this component is fairly new... but is there anyway to set the Add and Delete commands? Basically, they need to do things in my view model. As far as I can tell, they seem currently hard coded to actually add or remove items from the underlying collection.

I have a custom style for my connections. I set the target cap type as follows:
<Setter Property="TargetCapType" Value="Arrow1Filled" />

The result is an arrow pointing in the wrong direction, which is kind of ugly. See attached image!

How can I fix this?

Hello,

My list of data containing an image in byte [].
How I can include that image in a mail merge.
I tried using the INCLUDEPICTURE but does not work.

Is there any way?

Thanks and sorry for my English,

With the help of a sample application I found a memory leak in Richtextbox.
It just displays a Dialog with a RichTextBox and then closes the window. After closing a call to GC.Collect() is made.
If you repeat that (e.g. 15 times) than the consumed memory is growing.

Please, can you confirm it is a bug or tell me the solution?

Hi everyone,

I use a RadRichText box and I need to insert a Telerik.Windows.Documents.Model.Table object(It is generated in Runtime)
into a Document, and in each cell I add a placeholder using InlineUIContainer,
so the question is how can I disable editing of my cell that contains a placeholder,
because currently all my functionality works perfect but cells are editable.

Method below initializes a TableCell instance where a placeholder is injected.

private double InitDataCell(TableCell dataCell, DynamicColumnViewModel columnVm, bool isWidth100, double percent)

{

            double cellHeight = 0;

 

            dataCell.Tag = columnVm.DynamicCellData.TableID.ToString();

 

            if (isWidth100)

            {

                dataCell.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Percent, percent);

            }

            else

            {               

                dataCell.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Fixed, columnVm.Width);

            }           

 

            dataCell.TextAlignment = columnVm.Alignment;

            dataCell.VerticalAlignment = RadVerticalAlignment.Center;

            var paragraph = new Paragraph();

            paragraph.TextAlignment = columnVm.Alignment;

            dataCell.Blocks.Add(paragraph);

 

            dataCell.Background = columnVm.DynamicCellData.Background;         

 

            var tb = new TextBlock

            {

                Text = columnVm.Expression,

                Tag = string.Format("{0}{1}", DynamicTableCommon.DynamicTable.TABLE_TAG_ID_PREFIX, columnVm.DynamicCellData.TableID.ToString()),

                FontSize = columnVm.DynamicCellData.FontSize,

                Background = new SolidColorBrush(columnVm.DynamicCellData.Background),

                Foreground = new SolidColorBrush(columnVm.DynamicCellData.Foreground),

                FontFamily = columnVm.DynamicCellData.FontFamily,

                FontWeight = columnVm.DynamicCellData.FontWeight,

                FontStyle = columnVm.DynamicCellData.FontStyle,

                TextDecorations = columnVm.DynamicCellData.TextDecoration

            };

 

            tb.VerticalAlignment = VerticalAlignment.Bottom;

 

            tb.HorizontalAlignment = PlaceHolderReplaceManager.ConvertRadTextAlignmentToHorAlignment(columnVm.Alignment);

 

            System.Windows.Controls.Border border = new System.Windows.Controls.Border();

            border.BorderThickness = new Thickness(0);

            border.BorderBrush = Brushes.Transparent;

            border.Background = new SolidColorBrush(columnVm.DynamicCellData.Background);           

            border.VerticalAlignment = VerticalAlignment.Center;

            border.HorizontalAlignment = HorizontalAlignment.Center;

            border.Child = tb;

 

            border.Measure(new Size(Double.PositiveInfinity, Double.PositiveInfinity));        

 

            Size s = new Size(border.DesiredSize.Width + 1, tb.DesiredSize.Height - 1);

            var uic = new DynamicCellInlineUIContainer(border, s);                         

 

            paragraph.Tag = columnVm.DynamicCellData.TableID.ToString();

            paragraph.Inlines.Add(uic);

 

            cellHeight = uic.Height + 10;

 

            return cellHeight;

 }

and another question is - In what Table property can I save my ViewModel ID(table ID) value, because when
I try to save it in a Tag property, it dissapears when I do an export my Document(contains a table with Tag initialized property) to Html using HtmlFormatProvider?

Thanks in advance.
