DateTimePicker Problem

[Jeff Tang]

I have a question about DateTimePicker. Is there any function can validate the format of the input date? The problem is that even I type this "abcde" in the input area of the DateTimePicker, it still let me go when I out-focus the DateTimePicker. Thanks.

Hello Jeff,

The nice thing about the RadDateTimePicker (and other related date/time picker controls) is that it automatically validates input for you. When input is invalid, the control is highlighted (by default, in red) and a warning image is displayed inside the textbox. This functionality can be turned off if you'd like to manually validate the input by setting the DateInput-CausesValidation property to false. If you'd like to clear the invalid input and force the user focus back into the textbox, you can use the DateInput-ClientEvents-OnError event to do so. Here is an example:

	<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
	<script type="text/javascript">
	function OnError(sender, args) {
	sender.clear();
	sender.focus();
	}
	</script>
	</telerik:RadScriptBlock>
	<telerik:RadDateTimePicker ID="RadDateTimePicker1" runat="server">
	<DateInput>
	<ClientEvents OnError="OnError" />
	</DateInput>
	</telerik:RadDateTimePicker>

I hope this was helpful. If you have any further questions, please don't hesitate to ask.

Sincerely,
Kevin Babcock
