I need to change the background color of many Rad controls when they are disabled, RadDropDownList is one of them. I have searched up the forum but have not found a satisfactory answer. I am wondering if there is a built-in property that I can just set, so that each time RadDropDownList is disabled, its background color changes to black or gray, instead of the default disable-color. 

I understand that there is a built-in property to set default disable paint to false, it is shown in the code below. But then, how can I set up a custom disable paint? 

From filtering box, when I select Null and then select All then the following error occurs:

Item has already been added. Key in dictionary: '(Blanks)'  Key being added: '(Blanks)'

Please see the attached screenshot.

Hello,

I've had issues using Telerik for WinForms for a couple of weeks.

I thought I had cured it all last week when I updated my Telerik Control Panel and then updated the suite of controls.

The WinForms app I am working on will not allow me to add any Telerik controls to any Telerik form.

I tried repairing the Telerik WinForms components which didn't work.

I then uninstalled the Telerik WinForms components and re-installed them. Everything appears to install fine but my project will still not allow me to add controls (I can add RadForms though).

Every time I try to add ANY control I get a messagebox saying: "Failed to created component Rad.... The error message follows"....

Why is trying to re-add a reference to Telerik.WinControls.UI every time a new control is placed onto a form?

I am running Windows7 64-Bit - The references in my app are:

Telerik.WinControls

Telerik.WinControls.UI

TelerikCommon

Paths to files are:

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\Telerik.WinControls.dll

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\Telerik.WinControls.UI.dll

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\TelerikCommon.dll

Which are the latest downloads via Telerik Control Panel this afternoon.

Has anyone else experienced this issue? It's holding me up a lot.

Thanks.

hi friends,
I want to print a radchartview with a radgridview in the same document, Can you help me?

Is it possible to start each "grouping" of data on a new page when printing?

I can see simple properties for printing headers at the top of each page, printing the "grouping" column but nothing stands out to perform a page break for each grouping (in my case days of the week).
