    When I set the SelectedTabIndex on Page Load it does only work the first time the page is loaded. On the following postbacks it is not correctly handled.
    However, if I add the same logic in the OnPreRender, it works correctly.

    Is this by design? or is it a bug?

    Hello Ewald,

    I tested the issue that you describe using the code below and when I set SelectedTabIndex = 1 and have a button that makes a postback on the page, every time the page postback tab2 is rendered as selected. Please give it a try and let me know if you still encounter this issue. If so, could you clarify the exact version of the controls that you are using?
    <telerik:RadRibbonBar ID="RadRibbonBar1"  runat="server">
                <telerik:RibbonBarTab Text="tab1">
                    <telerik:RibbonBarGroup Text="group1">
                        <Items>
                            <telerik:RibbonBarButton  Size="Medium" Text="button1" ImageUrl="../images/Failed.png" />
                        </Items>
                    </telerik:RibbonBarGroup>
                </telerik:RibbonBarTab>
                    <telerik:RibbonBarTab Text="tab2">
                    <telerik:RibbonBarGroup Text="group2">
                        <Items>
                            <telerik:RibbonBarButton  Size="Medium" Text="button2" ImageUrl="../images/Failed.png" />
                        </Items>
                    </telerik:RibbonBarGroup>
                </telerik:RibbonBarTab>
            </telerik:RadRibbonBar>
            <br />
            <telerik:RadButton ID="RadButton1" runat="server" Text="RadButton">
            </telerik:RadButton>

    code behind:
    protected void Page_Load(object sender, EventArgs e)
        {
        RadRibbonBar1.SelectedTabIndex = 1;
         
        }
