Example
The code sample below demonstrates how you can use the ASPxTrackBar control in two ways. On the one hand, a user can easily choose the required value or item, on the other hand, you can show end-users the visual result of their actions.
In this example, an end-user can select a chemical element and see its melting point. Here we use two track bars. The first track bar is used to visualize melting points and looks like a thermometer scale. By design, an end-user cannot change its value directly, so the ASPxEdit.ReadOnly property for this track bar is enabled. The second track bar is used to select the required chemical element. All the defined elements are gathered to the ASPxTrackBar.Items collection. The ASPxClientTrackBar.PositionChanged event of the second track bar is handled to update the value of the first track bar.
The image below shows the result.
function OnPositionChanged(s, e) {
updateItems(s);
}
function OnInit(s, e) {
updateItems(s);
}
function updateItems(trackBar) {
var trackBarValue = trackBar.GetValue();
termometer.SetValue(trackBarValue);
}
