I’m using the DropDownCalendarControl version, and AutoPostBackValueChanged event occurs when this control lost focus.

On the previous version (7.403.0.9) when the date is selected, this event occurs immediately.

What would I like know is why of this behavior? Is it new? How can I configure it as in the older version?

Thanks a lot.

Hi Israel,

Thank you for your interest in Syncfusion products.

I am afraid that I am unable to reproduce the issue reported by you. I have checked this issue in the versions mentioned by you. But still postback occurs only when the date in the DropDownCalendar is changed and when the control is out of the textbox. Please refer the following code snippet, If your intension is to cause the postback even when changing the date in the DropDownCalendarTextBox by manually invoking postback at the client side function “ClientSideOnValueChange”.

AutoPostBackOnValueChanged="true" ClientSideOnValueChange="onChanged(this)" onvaluechanged="DropDownCalendarControl1_ValueChanged">

function onChanged(obj) {
__doPostBack(obj.HtmlID, obj.Value);//manually causing postback on changing values in the DropDownCalendar control

protected void DropDownCalendarControl1_ValueChanged(object sender, EventArgs e)
Label1.Text = "Value changed to ->" + DropDownCalendarControl1.Text;

I have also prepared a simple sample and it can be downloaded from the below link,

Kindly try this and let me know your concerns.
