Tab.Visible = false works but individual items will not go invisible .. i.e. TabItem1.Visible - false does not work

[John Fleet]

Windows 11 , Visual Studio 2019 (using VB.Net)  ,  Syncfusion.EJ.Web, Version=20.2460.0.36.

Cannot make individual TabItem invisible using code-behind e.g.   TabItem1.Visible = false does nothing, the item still appears.

Any ideas would be greatly appreciated.

Thanks, John

Hi John,

As per the shared details, we understand that you want to hide the individual TabItem from the ASP.NET Web Form VB Tab control. We have prepared a simple sample of ASP.NET Web Form VB with a Tab control to hide individual TabItem using the HiddenItemIndex property in the Tab control.

We suggest you set the list of TabItem index values in the HiddenItemIndex property to achieve your requirement. We have attached the prepared sample for your reference.

Refer to the below code snippet.

                <p>Pizza cooked to perfection tossed with milk, vegetables, potatoes, poultry, 100% pure mutton, and cheese - and in creating nutritious and tasty meals to maintain good health.</p>
