how can i disable one or more tab pages on a tabControl ?

Here's an idea:
First, create a variable such as: System::Windows::Forms::TabPage^ selectedTab
(load in the default tab into the selectedTab variable upon instantiation of the class)
Set the enabled property of the tabs then create a index changed event like so:

private: System::Void tabControl1_SelectedIndexChanged(System::Object^  sender, System::EventArgs^  e) {
             if(tabControl1->SelectedTab->Enabled == false)
             {
                 tabControl1->SelectedTab = selectedTab;
             }
             else
             {
                 selectedTab = tabControl1->SelectedTab;
             }
         }

Not a very profound Idea, but it works.

You can indeed set the enabled property, but it does not do anything in Visual Studio 2008. In VS2003, it would work fine. I'm trying to adjust to the new version because I just recently upgraded. I don't know why Microsoft would change this along with many other things that are stating to piss me off.

There is an Enable property for a Tab Page

 

You cannot see it because its Browsable attribute is set to false and EditorBrowsable is set to EditorBrowsableState.Never

 

You can set Enable property of a TabPage to true/false

 

The code which I described above works fine

 

//Enabled is the property used to set enable status of the tab page

        //If you want user should not able to select the disabled tab page

        //then handle the tabcontrol selecting event

        //here is a sample example

       

        //Check box enables or disables a tab page

        private void chkEnableTabpage2_CheckedChanged(object sender, EventArgs e)

        {

            if(chkEnableTabpage2.Checked)

                tabPage2.Enabled = true;

            else

                tabPage2.Enabled = false;           

        }

 

 

//When user is selecting the disabled tab page cancel the selection

        private void tabControl1_Selecting(object sender, TabControlCancelEventArgs e)

        {

            if (!e.TabPage.Enabled)

            {              

                e.Cancel = true;              

            }

        }

any other ideas please?...hope you can help me.. thanks in advance

You can do this using the enabled property, by setting it to false
