Property Value

true if tracing is enabled; otherwise, false.

Use this flag to check whether your page or application should output tracing information before it writes anything to the trace log.

The value of the IsEnabled property depends on the settings in the trace subsection of the system.web configuration section and the value of the trace attribute of the @ Page directive. The tracing option set in the page directive takes precedence over the option set in the configuration file. Setting the IsEnabled value programmatically takes precedence over both the page directive attribute and the configuration setting.


If you set the IsEnabled property to true for an entire application, you must explicitly set this property to false for any page in the application for which you do not want tracing information displayed.

The following code example demonstrates how you can determine whether tracing is enabled for a page. The code iterates through the rows in a dataset, writing trace statements for each row in that dataset.

if (Context.IsEnabled) { 
   for (int i=0; i<DS.Tables["Categories"].Rows.Count; i++) { 
     Trace.Write("ProductCategory", DS.Tables["Categories"].Rows[i][0].ToString());

if (context.get_IsEnabled()) {
    for(int i=0;i<ds.get_Tables().get_Item("Categories").
            get_Rows().get_Count();i++) {
