IsIndeterminate

Updated on Sep 24, 2025

RadProgressBar supports two modes of operation:

  • Determinate - aimed at scenarios in which the progress of an operation can be precisely measured.

  • Indeterminate - aimed at scenarios in which there is no way of determining the current progress of an operation.

The IsIndeterminate property specifies whether the control is in InDeterminate mode or not. The property is of boolean type and the default value is false. Below you can see examples of how to set the property in C# and XAML code:

XAML
	<telerik:RadProgressBar Height="30" Width="150" IsIndeterminate="False" Value="35" />
C#
	RadProgressBar progressBar = new RadProgressBar();
	progressBar.IsIndeterminate = false;
