Disable Menu Item from another page when called

[Wendy Hunt]

Hi -

I have a button, that when clicked... I want it to disable the menu until an action is taken, then have the menu operational (enabled) again by clicking a different button.  The purpose of my actions is to not let the user navigate off the page until they have finished editing and then have saved their work. 

I have been going through the postings and haven't found anything that works (I've tried many examples...Visible...EnableSelection...Enabled...etc). 

My menu is located on the Master page, and my calling code is located on the SOI page.

Here is the code I have so far...

      private void EnableNavigation(bool enabled)
      {
        RadMenu menu = (RadMenu)(Master.FindControl("RadMenu1"));
        menu.Enabled = enabled;
      }

This is how I call it from my Edit button click method... 
EnableNavigation(false);

Any other suggestions?  Should I be going about this in a different way?

This approach seems correct.

Do you think I should put in a support ticket, if it should be working but isn't?

Hi Wendy,

I'm sorry I didn't understand that this doesn't work.
Could you please prepare a simple page demonstrating the issue and send it in the support ticket so we to be able to test it? Thanks in advance.

Kind regards,

I am experiencing a very similar issue. I originally on initialization of the RadMenu set a menu item to be Enabled = false;

RadMenu menu = new RadMenu();
menu.Value = "Menu";
RadMenuItem toggledMenuItem = new RadMenuItem("Save File");
toggledMenuItem.Value = "ToggledMenuItem";
toggledMenuItem.Enabled = false;

I can successfully change the value of Enabled to be true when a different variable is populated using the following code: 

RadMenu foundMenu = FindControl("Menu") as RadMenu;
RadMenuItem foundMenuItem = foundMenu.FindItemByValue("ToggledMenuItem");
... // null checks
foundMenuItem.Enabled = true;

However, even with Enabled = true, the menu item is still displaying as disabled. Is there some sort of UI refresh that needs to occur in order to enforce the change?

Hello Liz,

I tested the scenario that you describe but I was not able to replicate the issue that you are getting. attached to this post you can find my testing page. Please give it a try and let me know how it goes from your side. Can you also modify it in a way that it demonstrates the issue that you have and send it back to me so I can observe it from my side? 

All the best,
Kate
