ComboBox

ComboBox is a combo box, a field whose value user can choose from a list of possible values, defined by you.

Usage

Fill From a Datasource

You can fill a ComboBox from a DataSource component with a function like this one:

function loadComboBox($sender, $params)
{
	$this->DataSource1->DataSet->first();
	while( ! $this->DataSource1->DataSet->EOF )
	{
		$this->ComboBox1->AddItem($this->DataSource1->DataSet->Fields["column_name"]);
		$this->DataSource1->DataSet->next();
	}
}

You can call it from your form’s onBeforeShow event.

Get Selected Item

You can get the selected item from PHP with the following code:

$selectedItem = $this->ComboBox->Items[$this->ComboBox->ItemIndex];

You can also use JavaScript:

ComboBox = jQuery('#ComboBox');
selectedItem = ComboBox.options[ComboBox.selectedIndex].text;
