I've run into a problem with Drag and Drop in the RadTreeListView wherein I have a (single) item that I want to drag to move it or copy it to another editor. When I start dragging near the border of the item (either drag up near a top border or down near a bottom border) the adjacent item gets selected for the drag as well, which is obviously not what I want.  Has anybody encountered similar behaviour ?

Dear @all,
I'm trying to find a way to define an appointment as "read-only". I don't want the user to be able drag&drop, delete or edit an appointment, nor insert a new appointment. I was examining the FirstLook example, which implements such a functionality using a StyleSelector. I was hoping to find some properties on an Appointment level to define these features. 
Is there any other way to configure these features without the need to create styles for it?

Thanks,
Meik

Hello,

I am trying to use the RadChart to bind to a Nested Collection.  I would like every member of the parent collection to represent a spline series that has a property named CollectionName property to bind to the Legend Label.  Then I want to have each child collection have its members mapped to the points along the spline.  This code works:

 

 

 

<Telerik:RadChart ItemsSource="{Binding Path=SeriesCollection,Mode=TwoWay}" x:Name="chartcontentseries" >

<telerik:RadChart.DefaultSeriesDefinition>

<telerik:SplineSeriesDefinition></telerik:SplineSeriesDefinition>

</telerik:RadChart.DefaultSeriesDefinition>

<telerik:RadChart.SeriesMappings>

<telerik:SeriesMapping CollectionIndex="0" LegendLabel="{Binding Path=CollectionName}">

                       (I have to have this set)       (This does not display the collection name!)

<telerik:ItemMapping FieldName="Percentage" DataPointMember="YValue"></telerik:ItemMapping>

</telerik:SeriesMapping>

</telerik:RadChart.SeriesMappings>

 

</telerik:RadChart>

However, I have to have a SeriesMapping for every collection that is added which is undesirable and the LegendLabel does not display the collection name.  Is there a way in XAML to set up a template for the series and have them automatically added and removed when the collection changes?  Or do I have to do it all manually in code behind?

HI, I want to use GridViewComboBoxColumn in a radgridview. But I found if I use RadWindow to hold the radgridview, the combobox dropdown list could not show. However, it could work if I create my own window.
Please see my attachment code.

Hello!
There are about six months since I've worked last time for a project that is using Telerik's dlls.
Now I have my hands back on it, and the first thing I tried to do was to update Telerik's libraries...
one thing I've noticed (and I bet there are others) is that my context menu for charts has disappeared - vanished - gone!
I'm now looking in your documentation and tutorials - and you are explaining how to add context menus to bars or other items in charts
but this is not the point! I had a general context menu for the entire chart that is now shown anymore when I'm right clicking the chart...


Is there something that I am missing here?

Thank you!

Hi I am using RadChart control with 2 series:
1. BubbleSeries
2. LineSeries.
The line series is used as regression line for all points found in BubbleSeries. The issue that I am facing is inability to "accurately" display the regression line. The regression line contains only two points; the y-intercept and the datapoint with max visible x value. The interpolation between those points is non existent. 
For example, when I have 2 points, the regression line just simply goes through those 2 points - dead on. However, it does not. I was thinking that I could start adjusting the YScale manually so that the points in BubbleSeries appeared to be on the line -> before I dig into that I wanted to ask and see if there is a better solution out there.

Attached is the the chart I am taking about; the point 1 and 4 lie directly on the line, however visually they don't appear. Ignore the points 2, 3, 5 -> in this case there are not used in calculating the points for LineSeries.

Hi,

I am working on an application where I need to dynamically hide/unhide the columns. I have implemented that functionality. However, after hiding a few columns at runtime, if I try to reorder column by dragging dropping the columns, the RadGridView adds blank columns at the hidden columns' places. I have created a small sample demonstrating the issue.

Xaml File:

Code Behind:

CustomerOrder class:

Now, at runtime I can show/hide a column by opening the combobox and checking/unchecking the checkbox for any column. However, after hiding the column, if I try to reorder the column, the gridview adds a blank column. For example, after hiding the CustomerPONumber column, if I drag the ShipToId column and place it after ProductName column, the gridview add a blank column after PharmacyNotes column(where the hidden column was before hiding).

Please help. All inputs are appreciated.

Thanks,
Jaspreet Singh.

Hi there,

When I place a readonly RadRichTextBoxes as template inside a RadCarousel and the focus is on the RadRichTextBox, the scroll wheel scrolls RadCarousel instead of the content inside the RadRichTextBox.  When I put a FlowDocumentViewer in place of the RadRichTextBox,  the scroll wheel scrolls correctly.  Is there a workaround for this?

Thanks

I'm using the new DragDropManager and trying to stay as close to the standard Windows/WPF approach as much as possible.  Most of the examples here use the RadDragAndDropManager, and I haven't been able to find examples using the new approach.

I have a form with 2 grids (i.e. RadGridView).  There are 2 possible drag/drop scenarios:

Scenario 1. Drag a row from the left grid, and drop onto a row in the right grid, in order to create an association.  In this scenario I need to determine how to  Provide a visual indicator of the drop target row.  This could be achieved by displaying the default mouse-hover highlight on a row, which seems to be turned off during drag/drop.  Is there a way to selectively turn this on and off from within the DragEnter and DragLeave events?

Scenario 2. Use drag/drop to reorder rows within either grid.   In this scenario I need to determine how to display a visual indicator of where the dragged row will be moved to, via an indicator line between the rows.  I notice that the RadTreeListView contains a nice template for this.  I can use the RadTreeListView instead of the RadGridView to take advantage of this.  However this indicator seems to be always on or off based on the IsDragDropEnabled property.  Can this template be toggled on/off from within DragEnter and DragLeave events?  Also how can I determine if the drop point is before or after the target row.

You'll notice that the right grid handles both scenarios, depending on the drag source.  Here is the DragOver handler which provides feedback on what effect (if any) the drop would have.  



Also I notice that unlike the RadDragAndDropManager, the new DragDropManager doesn't seem to support auto scrolling of a list. How would that be handled?

Thanks for your help.

Hi,

 

I have a gridview that is themed with Telerik Windows 7 theme, which is the general theme of the application and gets set at load time.  I want to add another grid in the Row Details section, however I want this nested grid to have a different theme for clarity (office black, or the white theme from the WPF Telerik examples).  Unfortunately, the nested gridview always take the same theme as the parent one.  I have tried to set the style differently, but it didn’t work.

 

 

<Style x:Key="RowDetailGridViewStyle" TargetType="{x:Type Controls:RmpReadOnlyGridView}"  BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:Office_SilverTheme, ElementType=telerik:RadGridView}}">

 

Any suggestion what I should do?

 

Regards
