Menu list in the drawer is blank when I press back button to the mainpage

[HannahC]

Hi SyncFusion,

When I press one of the selections in the menu list, APP will navigate to the corresponding page.

But neither press the button 'Back_Button' on the screen or the 'return button' on the left-top side of the screen, the drawer will be blank without any topics we have set. (you can see it in the video)

How to resolve it? Has anyone else responded to this issue?

Attached my source code and video

Please reply as soon as possible, thank you!

Hi Ruba Shanmugam,

I have another problem want to ask Syncfusion is that I want to check if the status of APP has the Internet ability to change menu item's text color.

I have a global parameter to get whether is the phone has Internet now regularly.

And I hope the menu item's text color will be changed automatically depends on the global parameter.

How do to achieve it?

Please also answer this question when you reply on Feb. 9.

Thank you very much!

Hi HannahC,

We have analyzed your query “Check App has the internet ability”. Please refer the following link to achieve your requirement,

Code snippet for example: 

  

var current = Connectivity.NetworkAccess;
Connectivity.ConnectivityChanged += Connectivity_ConnectivityChanged;
if (current == NetworkAccess.Internet)
{
     // When the internet connection is available.
}
else
{
      // When the internet connection is not available.
}

private void Connectivity_ConnectivityChanged(object sender, ConnectivityChangedEventArgs e)
{
       // Internet connection connectivity change.
}
