[Solved] how to change the default theme from xaml

[Raj A R]

HI team,

I need to add theme to my silverlight grid , i tried the below code but am getting the following error.
"The attached property theme was not found in the StyleManager."
i included this namespace:
 

 

xmlns

 

:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"

 

 

 

 

 

 

 

 

 

 

 

<telerik:RadGridView x:Name="RadGridView1" telerik:StyleManager.Theme="Office_Blue" AutoGenerateColumns="False">

 

my grid version is :2009.1.312.1020

-shinu.

Hello Raj A R,

Office_Blue and Office_Silver themes are available since our Q2 release.
That' is why you are getting that error.

Hi Raj A R,

Vista theme is available in our Q1 release, so I think that it might be suitable in your case.

You will need to refer to this namespace:

xmlns:controls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"

<telerik:RadGridView x:Name="RadGridView1" controls:StyleManager.Theme="Vista"/>

Kind regards,

hi Anastasia ,

it seems like i cant  set controls:StyleManager.Theme="Vista"   this directly

i imported this namespace :

xmlns

 

:controls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"   

 

and here is my grid declaration

 

<telerikGridView:RadGridView x:Name="rgvUnmappedAccounts"  

 

 

controls:StyleManager.Theme="Vista"

 

I'm getting this error
 AG_E_PARSER_BAD_PROPERTY_VALUE [Line: 73 Position: 74]    --- Inner Exception --- The given key was not present in the dictionary.

Hello Raj A R,

Do you have a reference to the Vista theme assembly (Telerik.Windows.Themes.Vista.dll) in your project?
Also to what namespace refers "telerikGridView"?

It should be:

<....
xmlns:controls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"

xmlns:telerikGridView="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
...>

<telerikGridView:RadGridView x:Name="rgvUnmappedAccounts" controls:StyleManager.Theme="Vista" />

Best wishes,

Hello Raj A R,

Setting Vista theme to the RadGridView is working fine on my end - please take a look at the attached sample project.
Maybe you can configure my sample project so that it behaves like your project and attach it back so we can debug it localy.
