showDropPanel();
The showDropPanel expands the panel to select the color.
To implement the example, the ColorCombo component named colorCombo must be available (see Example of Creating the ColorCombo Component). Add a handler of the color panel value change event:
// Add a handler of the color panel value change event colorCombo.ValueChanged.add(function (sender, args) { console.log("Color panel value is changed"); });
Expand the panel to select a color and get its sizes:
// Expand color panel colorCombo.showDropPanel(); // Get panel size console.log("Panel height: " + colorCombo.getDropPanel().getHeight()); console.log("Panel width: " + colorCombo.getDropPanel().getWidth());
As a result, color panel sizes are displayed in the console:
Panel height: 193
Panel width: 349
Select a color. The console displays the message about value change of the panel to select a color:
Value of the panel to select a color is changed
