Hi!

I use polyline in OrgChartDiagram with OrgTreeRouter. And I can't change TargetConnectorPosition property of polyline connection (only with Straight, Bezier). After change TargetConnectorPosition to "Right" it returned to initial state ("Left"). I need connection like red on image. How can I do it?

Occasionally we are seeing the following exception from our dashboards that show bar charts. Unfortunately I haven't been able to reproduce this in the lab: is this something that can be fixed?

System.ArgumentNullException

Value cannot be null.
Parameter name: owner

Hello All,

I have RadGridView  which hava a button embeded.  The button is binded with a command and the command parameter is the content of each row.  The bind expression of CommandParameter is "{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}".   The problem is the command cannot get its parameter.  I am sure the command binding is works, because it is working well if I using a DataGrid insteast.   Does anyone could help me.

Thank you && Best Regards

Hi

I'm not sure if WPF is the right technology or which Telerik control is best suited for the following scenario, so I would appreciate any recommendations that anyone can give me.

Secnario:

The user will load images from a database that were captured on camera.
The user will need to view at least 4 images at a time and maybe click one to view in full screen.(carousel control?).
The user should be able to draw circle on the image to highlight certain parts of the image.  This image must then be saved back to the database as a copy of the original with the users changes/highlights.

Can this be done in WPF with Telerik controls or can it be done easier with a different technology.

Thanks
Paul

Hi all,

I am new to telerik wpf and I want to know if I can make the Combobox work like autocompletebox.

Thanks,
Dona

Is there any way to get the RadAutoCompleteBox to stretch vertically to encompass added items, when using in multiple items mode? I'm sure its something simple, but I just can't find it!

Hi Telerik Team.

The CandlestickSeries seems to have an odd behavior for negative values. The attached image shows a graph where the candlestick values should decrease linearly from left to right, but they stop at around y=0.

What is a workaround for this?

I use Telerik Version 2012.2.912.40, WPF

Code:

Hi everyone,

I would like to open, focus and select all text in editable RadComboBox when my wpf form is opened.

So I set following properties:

OpenDropDownOnFocus="True" SelectAllTextEvent="GotFocus"

and I call the Focus(); on form's constructor.

But the comboBox is closed with no selected text in it.

Could you help me what am I doing wrong?

Thank you for your replies.

Using your pdfviewer control.
If I set IsInPanMode = "true" on the contol it doesn't seem to honor that setting. However if i have a toggle button that i bind to the FixedDocumentViewer.IsInPanMode property it seems to work.

I get the same effect with ScaleMode  - except here : if i set it directly on the control it doesn't work, but I also can't seem to get FixedDocumentViewer.ScaleFactor binding to work on other controls like Slider etc.

Any hints at what I'm doing wrong?

Hello,

I have been using the Scheduleview for my project. I modified the style of appointmentdialog through EditAppointmentDialogStyle, by changing the subject text block to radcombobox. I wanted to have list of string to be displayed in the combobox so that user can select the subject from the list. But the problem is I am unable to bind the list to the RadCombobox. It is always returning me Binding error. How can i solve this problem?

Thanks in advance,
Dheena
