Selected Tab Border Bottom

[Patrick Barranis]

Hey everyone,

       I am using the Office2010 theme in my application and am running into a problem with the selected tab on RadTabStrips.  The problem I have is that the default theme has a border at the bottom of the selected tab AND the on the top of the ContentPanel.  I could remove the bottom border on the tab, but the top border of the panel would still exist.  I don't want to remove the entire top border with the Panel, just the area right below the tab.  I have seen this effect happen with the other default themes, so I'm wondering if there is something I can change to get this look.  I hope that's clear, as it is hard to see the which tab is selected if the border between the tab and content panel exists.  The color changes, but that isn't too accessible to colorblind people.  Any ideas?   Thanks!

Hello Patrick Barranis,

Thank you for your question.

Please refer to the following code snippet. It implements the solution to your request:

public RadForm1()
        {
            InitializeComponent();
            this.Load += new EventHandler(RadForm1_Load);
        }
        TabItem previousTab;

        void RadForm1_Load(object sender, EventArgs e)
        {
            SetMargin((TabItem)this.radTabStrip1.SelectedTab);
            previousTab = (TabItem)this.radTabStrip1.SelectedTab;
        }

        private void radTabStrip1_TabSelected(object sender, TabEventArgs args)
        {
            SetMargin((TabItem)args.TabItem);
            previousTab.Margin = new Padding(0);
            previousTab.Children[2].Children[0].Margin = new Padding(0, 0, 0, 0);
            previousTab = (TabItem)args.TabItem;
        }

        private void SetMargin(TabItem tabItem)
        {
            tabItem.Margin = new Padding(0, 0, 0, -2);
            tabItem.Children[2].Children[0].Margin = new Padding(0, 0, 0, 2);
        }

I hope this helps. If you have any other questions, feel free to contact us.
