You can use the TickStyle property to modify the manner in which the tick marks are displayed on the track bar.
The following code example demonstrates how to use the TickStyle, Minimum, and Maximum properties and how to handle the ValueChanged event. To run the example, paste the following code into a form that contains a TrackBar control named TrackBar1 and a TextBox control named TextBox1. Call the InitializeTrackBar method from the form's constructor or Load event-handling method.
//Declare a new TrackBar object. internal: System::Windows::Forms::TrackBar^ TrackBar1; // Initalize the TrackBar and add it to the form. private: void InitializeTrackBar() { this->TrackBar1 = gcnew System::Windows::Forms::TrackBar; TrackBar1->Location = System::Drawing::Point( 75, 30 ); // Set the TickStyle property so there are ticks on both sides // of the TrackBar. TrackBar1->TickStyle = TickStyle::Both; // Set the minimum and maximum number of ticks. TrackBar1->Minimum = 10; TrackBar1->Maximum = 100; // Set the tick frequency to one tick every ten units. TrackBar1->TickFrequency = 10; // Associate the event-handling method with the // ValueChanged event. TrackBar1->ValueChanged += gcnew System::EventHandler( this, &Form1::TrackBar1_ValueChanged ); this->Controls->Add( this->TrackBar1 ); } // Handle the TrackBar.ValueChanged event by calculating a value for // TextBox1 based on the TrackBar value. void TrackBar1_ValueChanged( Object^ /*sender*/, System::EventArgs^ /*e*/ ) { TextBox1->Text = (System::Math::Round( TrackBar1->Value / 10.0 )).ToString(); }
