Styles in codebehind (.vb)

[Pan hal]

We need to set the background color and other properties  of few controls in runtime

How to set this in .vb file.

 

 

I tried this

control.style = Me.Resources ("Stylename")

I get the error for this.

Immediate reply will be appreciated as its urgent.

Hi Pan Hal,

Setting control's style in code-behind shouldn't cause any problems. Can you please elaborate on the scenario you need to implement? if you can send us a sample of your code, we will be able to further investigate the issue you are facing.

I attached an example of how you can set the style for RadButton and RadTreeView in code-behind. Can you please take a look at it and modify it to illustrate your scenario?

Let me know how it goes.

Here is my requirement.

 I have added a bitmapimage in Resource Dictionary
<BitmapImage x:Key="ImgBlackout" UriSource="/Images/Blackout.png"/>

Binding the bitmap in below in Bold.
<ControlTemplate x:Name="OffTemplate">

 

<Grid x:Name="PART_LayoutRoot" HorizontalAlignment="Stretch" VerticalAlignment="Center" Margin="4">

 

<Grid.ColumnDefinitions>

 

 

<ColumnDefinition Width="*" />

 

 

</Grid.ColumnDefinitions>

 

 

<Image Name="PART_Image" Source="{Binding Bitmap}" Grid.Column="0" Width="35" Height="35" ></Image>

 

 

<Grid Grid.Column="1" HorizontalAlignment="Stretch" Margin="4,0,4,0" >

 

 

<Grid.RowDefinitions>

 

<RowDefinition Height="15" />

 

</Grid.RowDefinitions>

 

 

<HyperlinkButton Name="PART_EditButton" Content="{Binding Activity}" Grid.Row="0" FontSize="12" />

 

 

<TextBlock Text="{Binding Description}" Grid.Row="1" FontSize="9" />

 

 

<StackPanel Orientation="Horizontal" Grid.Row="2">

 

 

<TextBlock Text="{Binding DisplayDate}" FontSize="9" />

 

 

</StackPanel>

 

 

</Grid>

 

</Grid>

 

</ControlTemplate>


Then need to set Bitmap  in .vb(codebehind)  

 

Public Overrides ReadOnly Property Bitmap() As System.Windows.Media.Imaging.BitmapImage

Get 

 

-----How to get the bitmapimage which is in ResourceDictionary

Return New Bitmap(??????)
End Get 

 

End Property

Hello Pan hal,

You could move the BitmapImage to the resources section of your UserControl and then you could easily get access to the resource:

1.Dim image As BitmapImage
2.image = Me.Resources("ImgBlackout")
