Adding buttons to a TabControl Tab in C#

Question

I have a TabControl in a windows form. I have pragmaticly added new tabs like so:

for (int i = 1; i < numOfLanguages; i++)
{
     // add a tab for each language
     string tabTitle = split[i];
     TabPage newTab = new TabPage(tabTitle);
     languageTabs.TabPages.Add(newTab);
}

inside the loop I want to set up the other controlls for each tab. mainly I want to add buttons. I have seen this code:

tabPage1.Controls.Add(new Button());

Based off this example I want to do something similar like:

languageTabs.SelectTab(split[i]).Add(new Button());

I know that this code wont work. Have been looking through the params and cant see anything that lets me do this kind of thing.

Any ideas community?

Answer 1

SelectTab moves the actual TabControl to the specified tab, it does not return the tab to let you manipulate it.

You can index into the tab pages as follows:

languageTabs.TabPages[2].Controls.Add(new Button());

If you have set the Name property on the TabPage on creation, then you can also find individual tabs by key:

for (int i = 1; i < numOfLanguages; i++)
{
     // add a tab for each language
     string tabTitle = split[i];
     TabPage newTab = new TabPage(tabTitle);
     newTab.Name = tabTitle;
     languageTabs.TabPages.Add(newTab);
}

...

languageTabs.TabPages[split[i]].Controls.Add(new Button());

(See MSDN for more)

Whichever is most convenient.

LINQ?

languageTabs.TabPages.First(tab => tab.Title == split[i]).Add(new Button());

This might be not reliable (crash) if your tabcontrol does not have tab with specific name, so you might want more reliable way:

if (languageTabs.TabPages.Exists(tab => tab.Title == split[i]))
{
    languageTabs.TabPages.First(tab => tab.Title == split[i]).Add(new Button());
}
