I have tried this solution: Open sitecore media library programmatically from asp.net button click
but this is not working for me. This gives a JavaScript error for .ascx
file code mentioned in answer.
This statement: Sitecore.PageModes.ChromeManager.postRequest
I am using Sitecore 6.3, included sitecore.js file. But get the script error the PagesMode ChromeManager
property caught for undefined.
Also tried to use
scForm.postRequest("", "", "", 'contentimage:open(id=FIELD1377303253)');
but this certainly wont issue the custom MediaBrowser command created for original solution.
