Select / highlight text on focus
Q:
Is there a way to select (highlight) the text from the input field when focusing the ComboBox?
A:
You can use the "OnOpen" client-side event of the ComboBox to do this. First, set up an event handler for this event:
<obout:ComboBox ... >
<ClientSideEvents OnOpen="ComboBox1_Open" />
</obout:ComboBox>
Then, declare these two JavaScript functions:
<script type="text/javascript">
var textBox = null;
function ComboBox1_Open(sender) {
var txt = getTextBox(sender);
txt.select();
}
function getTextBox(sender) {
if (textBox == null) {
var controls = document.getElementsByTagName('INPUT');
for (var i = 0; i < controls.length; i++) {
if (controls[i].type == 'text' && controls[i].id.indexOf(sender.ID + 'TB') != -1) {
textBox = controls[i];
}
}
}
return textBox;
}
</script>
