Assume that I have three tabs: Tab1, Tab2, and Tab3. In my XAML that creates the tabs, each has a UserControl that is used to display the page for that tab. I want to disable a tab based on the user interaction within the UserControl, How can that UserControl disable/enable a tab in this fashion?
In the attachment you can find a sample project demonstrating your scenario.
The easiest approach to this task is to create an event in the UserControl.
In the event handler you can compare the UserControl that has raised the event and the content of the each TabItem. When they match, simply disable the TabItem.
MyUserControl userControl = sender as MyUserControl;
if (userControl != null)
{
foreach (RadTabItem tabItem in RadTabControl1.Items)
{
if (tabItem.Content == userControl)
{
tabItem.IsEnabled = !tabItem.IsEnabled;
}
}
}
}
The sample attached is pretty self-explanatory.
Another way is to add a public property to the UserControl which is of type RadTabItem. This property, however, can only be set in code-behind. So if you are creating TabItems dynamically, you can take the approach with the property.
