Hi irshad1231,
I have checked you code and found the issue. You need to change the DataFormatString in the edit mode like below.
irshad1231 says:
<
EditItemTemplate
>
<
asp:TextBox
ID
=
"txtMeetingStartTime"
runat
=
"server"
ReadOnly
=
"true"
Text='<%# Bind("MeetingStartTime") %>'></
asp:TextBox
>
</
EditItemTemplate
>
From the above with the below
<EditItemTemplate>
<asp:TextBox ID="txtMeetingStartTime" runat="server" ReadOnly="true" Text='<%# Bind("MeetingStartTime","{0:yyyy-MM-dd HH:mm}") %>'></asp:TextBox>
</EditItemTemplate>
And
irshad1231 says:
<
EditItemTemplate
>
<
asp:TextBox
ID
=
"txtMeetingEndTime"
runat
=
"server"
ReadOnly
=
"true"
Text='<%# Bind("MeetingEndTime","{0:dd-MM-yyyy hh:mm tt}") %>'></
asp:TextBox
>
</
EditItemTemplate
>
From the above with the below
<EditItemTemplate>
<asp:TextBox ID="txtMeetingEndTime" runat="server" ReadOnly="true" Text='<%# Bind("MeetingEndTime","{0:yyyy-MM-dd HH:mm}") %>'></asp:TextBox>
</EditItemTemplate>
The format should be yyyy-MM-dd hh:mm or yyyy-MM-dd HH:mm
2017-09-26 02:29
or
2017-09-26 14:29
As you are assigning format as format: 'Y-m-d H:i' in the jquery.
So as per the format in jquery you have to change the html format.
