Dynamic tool tips for Tab control

Hi all

I have a tab control with ShowToolTips = true.
It works fine for static tool tips that I assigned to the tabs using ToolTipText property.
Now I need to make the tool tips dynamic, i.e. change the tip's text before showing it, depending on the tab contents. So, I'd like to use something like MouseHover event to check which tab I am in and change the corresponding ToolTipText. Unfortunately, TabControl.MouseHover event does not tell me which tab the mouse hovers on.

Is there any other event/property I can use?

Thank you

Shouldn't you be checking the event on a TabPage (and not TabControl)? TabPage is a Control and handles MouseHover.

TabControl supports selectedIndexChaged event. You can try this:

C#

private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
{
    if (tabControl1.SelectedTab == tabPage1)
        toolTip1.SetToolTip(tabControl1, "TabPage1");
    else if (tabControl1.SelectedTab == tabPage1)
        toolTip1.SetToolTip(tabControl1, "TabPage2");
}

But perhaps you shoud consider to assign tooltip value for each individual tab page. This way you don't need to do any coding.

I need to change the tool tip text while mouse is hovering above the tabs, without changing selected tab - the same way as static tips are shown

Now I understand. This is tough with .NET build-in tab control. However there are several tab controls you can find in CP. Below are just two examles (there are more). You can download one of them you like most and extend functionality to support your need.
