Customizable number of Items on Popup in Windows Forms NavigationView

Navigation View now allows setting the maximum number of items to be displayed on its pop-up and has an option to cancel the pop-up. BarPopUp event can be used to achieve this.

// Sets the maximum items to be displayed.

Private this.navigationView1.BarPopup += new EventHandler<Syncfusion.Windows.Forms.Tools.BarPopupEventArgs>(navigationView1_BarPopup)

private void navigationView1_BarPopup(object sender, Syncfusion.Windows.Forms.Tools.BarPopupEventArgs e)

{

if (e.CurrentBar.Text.Equals("TestSample"))

{

e.Cancel = true;

}

if (e.CurrentBar.Text.Equals("Program Files"))

{

e.MaximumItemsToDisplay = 13;

}

else

{

e.MaximumItemsToDisplay = 5;

}

}
