Change tab color and restore to original color

[joseph_korn]

As per the instructions given in this thread: http://www.telerik.com/community/forums/thread/b311D-mkmhd.aspx I was able to successfully change the backcolor of a tab programmatically.  When I try to reset the tab color back to its original color, it works fine, except that the color stays changed until I hover over the tab, and then it fully returns to normal.

For example, I have a tab strip with the default blue colored tabs.  I click a button to change one of the tabs to yellow, and it works.  I click another button to change the color back to the original blue color, but the tab still remains yellow.  When I hover my mouse over the yellow tab, it changes to the hover color, and when I hover away from the tab, it returns to its original blue color.

Here is a sample of my code used to make the tab turn yellow:

            Dim oFillSelector As New ClassSelector("TabFill")
            Dim oTabFill As FillPrimitive = TryCast(oFillSelector.GetSelectedElements(Me.tsTabs.SelectedTab)(0), FillPrimitive)

            If oTabFill.BackColor <> Color.Yellow Then
                oTabFill.BackColor = Color.Yellow
                oTabFill.BackColor2 = Color.Yellow
                oTabFill.BackColor3 = Color.Yellow
                oTabFill.BackColor4 = Color.Yellow
            End If

Here is the code I use to return all tabs to their default color:

For i as int32 = 0 to Me.tsTabs.Items.Count -1
        Dim oFillSelector As New ClassSelector("TabFill")
        Dim oTabFill As FillPrimitive = TryCast(oFillSelector.GetSelectedElements(Me.tsTabs.Items(i))(0), FillPrimitive)

        oTabFill.ResetValue(FillPrimitive.BackColorProperty)
        oTabFill.ResetValue(FillPrimitive.BackColor2Property)
        oTabFill.ResetValue(FillPrimitive.BackColor3Property)
        oTabFill.ResetValue(FillPrimitive.BackColor4Property)
Next

Please let me know what I am doing wrong, as it is quite annoying to have to hover over all the tabs everytime I want to see which ones are really supposed to have a different backcolor.

Hi joseph_korn,

Thank you for this question.

After you reset the values of all the BackColor properties, you should call the ForceApplyTheme() method:

Me.tsTabs.RootElement.ForceApplyTheme();

If you have additional questions, feel free to contact me.

All the best,
