Asked On May 25, 2019 07:18 PM UTC

 I am using the latest SF library on a Windows Forms application. I dropped the NavigationDrawer on the MetroForm and configure it so that it has a single Header Item and underneath several Items.

When I run the form I can click on the items BUT I do not know how to catch that in an event. The Help system does not give any clues as to how to do it. The designer window shows many events for this control but none of them is about a Drawer Item Selected. Out of curiosity I used the Click event but there you get only the empty EventArgs that does not provide any information.

BTW I also tried to add a Header Image to the Header Item to try to imitate what is shown on the Help pages but when I click on the "..." to select an image the designer gives a Null Reference Exception (I logged that as a bug using the Feedback System)

Hi Emilio, 
  
Thank you for your patience. 
  
We have provided event to notify the item selection in NavigationDrawer and you can download the patch from following location. Please refer the following code for the same, 
  
[C#] 
this.navigationDrawer1.ItemClicked += NavigationDrawer1_ItemClicked; 
  
private void NavigationDrawer1_ItemClicked(object sender, DrawerMenuItemClickEventArg e) 
        { 
           //For your customization 
        } 
  
  
Recommended approach – exe will perform automatic configuration       
Please find the patch setup here:                            
  
Advanced approach – use only if you have specific needs and can directly replace existing assemblies for your build environment                        
Please find the patch assemblies alone from: 
  
Please find the NuGet from the below location:      
 
Assembly Version: 17.1.0.47  
Installation Directions:  
This patch should replace the files “Syncfusion.Tools.Windows” under the following folder.  
$system drive:\ Files\Syncfusion\Essential Studio\$Version # \precompiledassemblies\$Version#\4.0  
Eg : $system drive:\Program Files\Syncfusion\Essential Studio\17.1.0.47 \precompiledassemblies\17.1.0.47 \4.0  
   
To automatically run the Assembly Manager, please check the Run assembly manager checkbox option while installing the patch. If this option is unchecked, the patch will replace the assemblies in precompiled assemblies’ folder only. Then, you will have to manually copy and paste them to the preferred location or you will have to run the Syncfusion Assembly Manager application (available from the Syncfusion Dashboard, installed as a shortcut in the Application menu) to re-install assemblies.  
   
Note: To change how you receive bug fixes, ask your license management portal admin to change your project’s patch delivery mode.  
   
   
Disclaimer: If you have received other patches for the same version for other products, please apply all patches in the order received. Please note that we have created this patch for version 17.1.0.47 specifically to resolve the following query reported in the forum 144853. These changes will be included in our main release 2019 Volume 2 which is expected on end of June 2019.

Subburaj Pandian V

These changes will be included in our main release 2019 Volume 2 which is expected on end of June 2019.  

I'm using Volume 2, and my DrawerMenuItem classes have no ItemClicked method as stated here.

Am I doing something wrong, or did this not make it into the Volume 2 release?

Thanks!
