DateTimePicker lose date value after postback

[Unknown]

Hello,

I have following problem: on a View I have a form with two DateTimePickers to select a time span and some other controls. If I submit the form and there are validation errors, the controller returns to this view, but the DateTimePickers are blank, they don't save the selected date's. Is there any possibility to prevent the DateTimePickers from loosing their date's after postback? Or at least can I somehow manually set the date's in the DateTimePickers?

Hi Roman Suska,

Thanks for using Syncfusion products,

 

We have analyzed your query. We will let you know that we can achieve your requirement using our existing property “enablePersistance” (which is used to Enables or disables the state maintenance of DateTimePicker) in DateTimePicker control. By setting this value to “true” we can maintain the DateTimePicker value even after the post back the form.

 

Please find the below code snippet,

 

[_cshtml]

@Html.EJ().DateTimePicker("SampleDateTime_1").EnablePersistence(true)

                            @Html.EJ().DateTimePicker("SampleDateTime_2").EnablePersistence(true)

 

For your convenience we have prepared the sample based on this. Please find the sample from below location

Please let us know if you have further queries.

Hi Sasikala Nagarajan,

ok I got it, but I have another question. I have a dropdown list with places, that are available on the selected time span. This dropdown is populated with Ajax. After postback or when the page loads I run the script with $(window).load to populate the dropdown list. The problem is with this line:

var startDateTimeObj = $("#dataRozpoczecia").data("ejDateTimePicker"); 

The jQuery code returns "undefined", so I think the control isn't created yet. How can I get the value set on the DateTimePicker after postback or page loading?
