Hi I am wraiting an application where I need to do something at the begining of every appointment using the radscheduler.

How can I have an event every time that an appointment is starting without opening the alarm window of the radremainder?

 Thanks for the help

I have a winforms project which uses "plugins" which get resolved at runtime. The core project loads and displays user controls that are defined in the plugin .dlls. I have recently updated my primary project to use version 2015.3.930.40 versions of the controls. 

When it now tries to load a "plugin" that references an older versions (example 2014.2.715.40) in gets an error.  

I cannot control which versions of plugins other developers use to make their plugins and I need to make sure I load them by reflection. 

I saw this older thread from 2010:  http://www.telerik.com/forums/how-to-make-telerik-assemblies-of-different-versions-coexist

I was hoping there was a to fix this now. 

Thanks in advance for any help,

Hi, I'm just getting to grips with Chartview for Winforms and wondered what the best way is to allow someone to draw shapes and lines on a chart, and have the ability for those shapes to zoom and pan with the chart? I saw a few posts suggesting that it might be possible to use RadDiagram together with Chartview to achieve this?

Any helpful reposnses would be grately appreciated.

Greetings,

I am attempting to search a loaded PDF document for a specific bit of text which can be located via the navigator controls but the PdfViewerElement.Find isn't able to find it.

 I have included my code below which I got from the online documentation and you can see the pdf I am searching at this address http://ab.rockwellautomation.com/Programmable-Controllers/MicroLogix-1100#documentation

 Is there something I am doing wrong in my code that the PDFNavigators search function can locate text but mine cannot?

Thank you!

Hello there,

I have some problems with the gridview control when using three-stated checkboxcolumns. To recreate the problem, create a new telerik winforms project and in the mainform add a gridview. Dock this gridview to the form. 

 Then, add the following columns and change the options as follows:

GridViewTextBoxColumm

 FieldName: Id

 Name: Id

 MinWidth: 80 (important for later)

GridViewTextBoxColumm
FieldName: Name
Name: Name
MinWidth: 150

GridViewCheckBoxColumn

FieldName: Test1

Name: Test1

MinWidth: 80

ThreeState: true

GridViewCheckBoxColumn
FieldName: Test2
Name: Test2
MinWidth: 80
ThreeState: true

GridViewCheckBoxColumn
FieldName: Test3
Name: Test3
MinWidth: 80
ThreeState: true

GridViewDateTimeColumn

FieldName: CurrentDateTime

Name: CurrentDateTime

MinWidth: 200

GridViewDecimalColumn

FieldName: Nr

Name: Nr

GridViewCheckBoxColumn

FieldName: Test4

Name: Test4

MinWidth: 80

The extra columns and minimal width are only there to make the sure you can scroll horizontally.

Change the codebehind for RadForm1 to the following:

To trigger the error, run the project, do not enlarge the window, and try to add a new line. Fill in a new id and a new name, keep Test1 to it's initial (third) state and uncheck Test2. Then, without pressing enter, scroll left and right by grabbing the horizontal scrollbar and moving quickly left and right. At that moment you should get the following error:

So, my question would be: what am I doing wrong and how can I avoid this?

Thanks in advance

 Hi!

I have a Telerik GridView (RadGridView1), and two columns of this GridView contains cells (GridDataCellElement) with charts (RadChartElement())

Durung the scrolling all the cells are distorting. I've read a lot of topics, but I still don't understand how should I fix it. My case is different, than others.

How can I fix it?

I'm having issues with the theming of the RadDropDownList using the VisualStudio2012Light theme. I've set my RDDL to have a height of 20px and without theming the text vertically centers normally and there are no hassles whatsoever. As soon as I apply the theme then things start getting pear shaped.

The RDDL automatically adjusts its height to 24px which is not what I want. This mismatches all the other controls I have with the same theme - none of them resize when the theme is applied.

When I adjust the height of the RDDL to 20px after the theming has been applied the height adjusts fine but the text remains in the same position and gets cut off. The offset doesn't adjust.

I know in the past themes have been buggy at times but this is the first time I've come across this particular issue. I can say for certain that with 2013.2.724.40 this wasn't an issue but after checking some other versions it was also a problem in 2015 Q2.

I'm using VS2012, .NET 4.0. The attached image shows:

1. How the text is cut off

2. How the RDDL resized itself

3. How the RDDL compares to a RadTextBox and a RadDateTimePicker

Hi,

I have a problem with unselecting the new Row in my grid.

To explain the problem, i have a grid, where the user can add data to by using the new Row.

When clicking the new Row, it gets populated with some default data and can be edited.

I wanted to make sure the edited data gets saved when the user leaves the new Row,

so i used the UserAddingRow event to open a MessageBox to ask the user if he wants to save.

If yes, all right.

If no, I use e.Cancel to reject the data.

=> At this point I would like the new Row to change back to the initial "Click here to add new row" state,

but it stays selected or defined as CurrentRow. The data is gone, but an empty row stays as long as I don't switch to

another row manually, even when the data bound to the grid changes.

I can't find a way to unselect the row or set CurrentRow = null, as it seems not to be possible out of the event.

Also there seems to be no other event to hook up to after UserAddingRow when cancelled.

Maybe there is an easy way of unselecting, or maybe I'm using the wrong event for that purpose.

I would be glad for some help. :)
