xaml - Change SelectedIndex without triggering SelectedIndexChanged? -

i'm having problem. want set default value (kind of 'header text') combobox. purely aesthetics purposes , describe user initial purpose of combobox.

i have selectedindexchanged combobox opens view.

my problem is, change .selectedindex '0' value 'header' selected. when change index, seems cause infinite loop, until .selectedvalue of combobox becomes null , .selectedindex becomes '-1' throws exception.

my code below:

public myview()     {         this.initializecomponent();         load += myloadevent();     }  private void myloadevent(object sender, routedeventargs e)     {         mycombobox.selectedindex = 0;     }  private void mycomboboxselectionchanged(object sender, selectionchangedeventargs e)     { // use combobox value , go other view } 

thank you!

you can skip first event adding flag variable. skip first 1 or next event after setting processevent false:

public myview() {   this.initializecomponent();   load += myloadevent();   processevent = false; } ... private void mycomboboxselectionchanged(object sender, selectionchangedeventargs e) {     if ( processevent )    {     // use combobox value , go other view      // event processing       ...    }    processevent = true; }
