jQGrid datetime server side filter not working with specific date format

Question

jQGrid datetime server side filter not working with specific date format

We have used Trirand.Web.UI.WebControls.JQGrid in our Asp.Net application, We have also enabled server side filtering setting LoadOnce = false. We have also implemented localization for Date format for that we are using below code

JQGridColumn jc = new JQGridColumn();
jc.DataFormatString = "{0:" + UserDateDisplayFormat + "}";

CustomFormatter jcformatter = new CustomFormatter();
jcformatter.FormatFunction = "FormatNullDateCellValue";
jc.Formatter.Add(jcformatter);

Where "FormatNullDateCellValue" JavaScript function is converting datetime format for display in grid.

Now we are facing issue with specific date format "dd-MM-yyyy" when date is lower then 12 (e.g. 10-02-2018).

For server side in Asp.Net we have jqGrid_DataRequesting method where we got filtered result with 1 record count.

But from there when code reaches to loadComplete(data) JavaScript method we found record count 1 but not row data.

This is strange from we have got so far http://www.trirand.net/forum/default.aspx?g=posts&t=3964 but this is not helping us.

Thanks in Advance.
