Tab Control

Question

I have added a tab control to a win user form but the tabs will not display text! I have the tab named tbctrl1 and I tried double clicking the form and adding in

private void tbctrl1_Click(object sender, EventArgs e)

{

tbctrl1.Text = "This is Tab 1";

}
but it continues to show a blank tab with no text for the name. Did I place the naming code in the wrong location? Or am I naming the tab the wrong way?

I'd assumed that tbctrl1 was the TabControl itself but the error you're getting suggests that it's actually one of the TabPages? Incidentally, a TabPage's tab is not regarded as being part of the TabPage but part of the TabControl. Consequently, when you click on the tab, it's the latter's Click event which fires. The DrawMode property shoudd be set to 'Normal' unless you're drawing the tabs yourself in the handler for the DrawItem event. That will be why they're not displaying when you use the 'OwnerDrawFixed' setting.

I don't know or understand the reasoning behind this, but I set my DrawMode Property to 'Normal' and the tabs show the actual names I set up. If the DrawMode Property is set to 'OwnerDrawFixed' the tab names do not display.

Clicking on the actual tab itself I have the Text set to display as I need it to, however it is not actually displaying when I run the program. If I attempt to use tbctrl1.TabPages[0].Text = "This is Tab 1"; I get a compile error of 'System.Windows.Forms.TabPage' does not contain a definition for 'TabPages' and no extension method 'TabPages'accepting a first argument of type 'System.Windows.Forms.TabPage'c ould be found.

A Tabcontrol has a TabPages collection and, if you click somewhere on the first TabPage in the VS designer, then you'll see that it has its own Properties Box from which you can set its Text property. Alternatively, you can set it in code: tbctrl1.TabPages[0].Text = "This is Tab 1";
