Question

Initially I thought that it will be a very trivial functionality but now I am not able to implement it.

My requirement is simple. I am programmatically setting the content of a TabItem. The content will be usercontrols. I want to set the text of the header of the TabItem based on the content.

Content doesn’t have a changed event so I am confused as to on which event should I write code.

Also I’m not able to find any style or anything on the net.

Any suggestions? Please help. Thanks in advance.

PS: Please let me know if you need any further information from my side.

I think i got it. Not sure if this is the optimum solution so if anybody has a better solution than this then it will help me a lot.

I made a custom tabitem and overrided OnContentChanged (Didnt knew that there is an overridable OnContentChanged :)). So my code is like below.

    public class TabItemData : TabItem
    {
        protected override void OnContentChanged(object oldContent, object newContent)
        {
            if (newContent.GetType().Name.ToLower().Contains("mycontrolname"))
                this.Header = "control name";
            else
                this.Header = "old name";

            base.OnContentChanged(oldContent, newContent);
        }
    }
