Sometime we need to send parameter to our custom page from NavBarItem, but as NavBarItem does not support JavaScript property so we can pass parameter to our custom page using openIsvWin function (Unsupported)

Code to create NavBarItem

<NavBarItem Icon=”/_imgs/ico_18_debug.gif” PassParams=”1″ URL=”http://MyPage.aspx” Id=”MyItem”>
      <Titles>
         <Title LCID=”1033″ Text=”ISV Default” />
     </Titles>
 </NavBarItem>

Paste this code on formload event

navBarItem=document.getElementById(‘MyItem‘);
if(navBarItem!=null)
{
navBarItem .onclick = function() {

openIsvWin(‘http://MyPage.aspx?ParameterName=’+crmForm.all.ParameterFieldName.DataValue, false, -1, ”);

}}

Hope it will help somebody at right time 🙂
