Hi,
How can I postback when I use the keyboard to change the value in the WebDatePicker? I know how to accomplish this by selecting from the calendar.
Thank you,
Trent
Hi Trent,
You may enable autopostback on enter key. Similar way can be triggered a postback on lost focus (value change). To trigger postback on other keys or events, application may process corresponding client side events (like KeyUp), check event/keyCode, check current value in editor (if it is valid and complete), etc, and call __doPostBack(sender.get_uniqueID(), '') or use similar statements.
Example for autopostback:
<ig:WebDatePicker ID="WebDatePicker1" runat="server"> <AutoPostBackFlags EnterKeyDown="On" /></ig:WebDatePicker>
Hi Viktor,
When I added the AutoPostBackFlags-EnterKeyDown="On", the value change from selecting the date on the calendar does not trigger the postback.
After I select a date, the calendar closes right away so I can't choose another date. Also, if my format in the field is just the date and no time, I don't see the need to keep it in edit mode. I can use the workaround, but maybe there could be a property to postback after calendar closes.
Thanks,
Hello Trent,
What I can suggest for achieving your requirement is handle WebDatePicker`s KeyDown event which is fired even when the DateTimePicker is on focus. In the event current text being entered is accessible via sender`s get_text() method as such: sender.get_text(); . Please note that string returned from this method contains everything visible in the input textbox of the DatePicker, including the slashes used to separate the date ("_2/__/____"). What I can suggest is take this string, split it by the slash("/") symbol and check whether the input is a valid date. If the input is a valid date a CallBackManager object for the WebDatePicker control may be executed to cause a PostBack as such:
var callbackObject = sender._callbackManager.createCallbackObject(); sender._callbackManager.execute(callbackObject);
var callbackObject = sender._callbackManager.createCallbackObject();
sender._callbackManager.execute(callbackObject);
I hope this helps.
Let me know if you have any questions.
I was wondering did you have a chance to try my suggestion? Please feel free to contact me if you have any additional questions regarding this matter.
Hi Vasya,
I managed to get it working by adding the Javascript. However, I don't feel that is the right solution. I used Infragistics control because it is suppose to write all that code for me. Why should I enable something to postback and then have to write the Javascript code to postback.
Thank you for your feedback. I am glad that you managed to resolve the issue.
