This tutorial demonstrates connecting a RadTrackBar to a RadTextBox
control. Setting the trackbar slider position changes the value in the
text box.
- Place a RadTrackBar, RadTextBox and RadLabel
controls on a form.
- Select the RadLabel control and set its Text property
to "Current Value:"
- Select the RadTextBox control.
- Set the value of the Text property to an empty
string.
- Select the RadTrackBar control.
- Set the Maximum property to 30.
- Click the Events toolbar button in the Properties
window.
- Double-click the ValueChanged event.
- Replace the automatically-generated event handler with the following
code:
Copy[C#]
void radTrackBar1_ValueChanged(object sender, EventArgs e)
{
this.radTextBox1.Text = radTrackBar1.Value.ToString();
}
Copy[VB.NET]
Private Sub radTrackBar1_ValueChanged(ByVal sender As Object, ByVal e As EventArgs)
Me.radTextBox1.Text = radTrackBar1.Value.ToString()
End Sub - Press F5 to run the project.
- Move the slider on the trackbar using the mouse. The text box will
update to show the new slider position.
