Hello,

I can't animate IsIndeterminate property on a RadProgressBar. I have a custom control with a ProgressBar in it. The custom control has severals VisualState and I want to change the IsIndeterminate property according to the state of the control.

Here is my code :

</ObjectAnimationUsingKeyFrames>

</Storyboard>

</VisualState>

</ObjectAnimationUsingKeyFrames>

</Storyboard>

</VisualState>

</ObjectAnimationUsingKeyFrames>

</Storyboard>

</VisualState>

</ObjectAnimationUsingKeyFrames>

</Storyboard>

</VisualState>

<VisualState x:Name="InProgress">

<Storyboard>

<ObjectAnimationUsingKeyFrames Storyboard.TargetName="progressbar_Status" Storyboard.TargetProperty="(RadProgressBar.IsIndeterminate)" BeginTime="0:0:0">

<DiscreteObjectKeyFrame KeyTime="0:0:0" Value="True" />

</ObjectAnimationUsingKeyFrames>

</Storyboard>

</VisualState>

I have tried with "TargetProperty="IsIndeterminate", but doesn't working neither. Can you help me ?

Thanks

Hello Stephane,

You can try the following:

<Grid x:Name="LayoutRoot" Background="White">

<VisualStateManager.VisualStateGroups>

<VisualStateGroup x:Name="CommonStates">

<VisualState x:Name="InProgress">

<Storyboard>

<ObjectAnimationUsingKeyFrames Storyboard.TargetName="progressBar1"

Storyboard.TargetProperty="IsIndeterminate">

<DiscreteObjectKeyFrame KeyTime="0">

<DiscreteObjectKeyFrame.Value>

<System:Boolean>True</System:Boolean>

</DiscreteObjectKeyFrame.Value>

</DiscreteObjectKeyFrame>

</ObjectAnimationUsingKeyFrames>

</Storyboard>

</VisualState>

</VisualStateGroup>

</VisualStateManager.VisualStateGroups>

<StackPanel Width="200" HorizontalAlignment="Center" VerticalAlignment="Center">

<telerik:RadProgressBar x:Name="progressBar1" Height="30" />

<Button Content="Go To Indeterminate" Click="Button_Click" />

</StackPanel>

</Grid>

private void Button_Click(object sender, RoutedEventArgs e)

{

VisualStateManager.GoToState(this, "InProgress", false);

}

Let me know if it helps.
