I need to find the absolute screen coordinates of a floating dockwindow from within code running inside a form hosted inside this dockwindow. I have tried different things but all I get back is the screen location of the original form that the rad dock control is hosted.

Any ideas how I can achieve this?

Regards,

George

[Solved] AutoCompleteBox: Determine if text came from AutoCompleteItems

Hey Telerik!

I would like to determine if a newly created text block was from the autocompleteitems list or not.

I noticed that your AutoCompleteItems used a RadListDataItemCollection. Is it possible to use a collection of objects ?

If not, I will be adding items to the AutoCompleteItems in the form of

items.Add(New RadListDataItem("Joe Smith", "GUID HERE"))

I was assuming the CreateTextBlock event could be used to determine if there was a GUID value attached or not. I could use this as a way to determine if the item was from the AutoCompleteItems. I am not sure how to get the data value for the text block element or hopefully custom class for the newly created block.

Thanks

Pressing the tab key while the RadRichTextBox has focus, always takes the focus away from the control, even when AcceptsTab is set to true.

Zooming Images

I want to show thumbnail images in a ListView in IconView. I got the thumbnail images in a fixed size and I want to show them smaller. I set the image property of the listviewdataitem to the thumbnail and the Itemsize property of the listview to a size smaller than the thumbnails. Now I only see a part of the thumbnail in the listviewdataitems. Can I zoom the images to see the whole image in the listviewdataitem?
Thanks in advance!

Advanced GridViewColumnGroup?

Hi, I have a very special requirement to address.

I'm looking to manipulate the RadGridView to some sort of PivotTable, but I need to edit the objects that the grid will be bound to (would be great to run in bound mode), and by edit I mean drag and drop the 'Projects' to different weeks of months (but that's another problem).

My current problem is about altering the UI of the grid, so that it can be more intuitive for the user and also easier to maintain.

Please see the screenshots in attachment to understand my goal.

Thanks,

Pan and Zoom

I'm using the Q1 2013 distribution and I'm having trouble using the pan and zoom functionality. When I zoom in on a radchartview, I can only pan around a small set of values (I'm using a scatterpoint chart). I'm not able to pan the entire chart this way.
I'm trying this with a simple scatterpoint chart created and configured by the Property Builder, with no extra configuration. Is this the expected functionality?
Also, the zooming occurs at a fixed point of the chart, not relative to the mouse. Is it possible to make it work this way (relative to the mouse)? i found this article http://www.telerik.com/community/forums/silverlight/charting-kit/zoom.aspx Is it possible to create a similar project for WinForms?

decrypt data using SP on a windows form

Hi forum,

Is there a tool/object that enables me to decrypt encrypted data from a sql server table and display it on a windows form?
I have an employee table with encrypted information. What i need to do is read the employee table to enable the user to see the employee information. I need to create 2 forms, one for inquiry and the other one for maintenance.
Obviously the maintenace will work the opposite, the user will enter information and i need to update the data using encryption.
I already have a Stored Procedured that does the encrypt/decrypt process.
I am new doing this and would like to use the winforms objects to do this.

Regards,
Manuel Roman
