Question

I am trying to remove all tabs from a TabControl where the tab index is not a specified index.

I have this so far:

for (int i = tabcontrolOptions.TabCount - 1; i >= 0; i--)
{
    if (i != tabNo)
    {
        tabcontrolOptions.TabPages.RemoveAt(i);
    }
}

But that removes all tabs, and not the specified tabNo. What am I doing wrong?

Answer 1

When you remove a tab, the tabs get reindexed. Actually, what you’re doing shouldn’t be affected by that. But try the below anyway, maybe it will help.

Refer to the tab object explicitly, not by index:

var tabToKeep = tabcontrolOption.TabPages[tabNo];
for (int i = tabcontrolOptions.TabCount - 1; i >= 0; i--)
{
    if (tabcontrolOption.TabPages[i] != tabToKeep)
    {
        tabcontrolOptions.TabPages.RemoveAt(i);
    }
}
