How to replace only default date with blank in date field of JQgrid

Question

I am using JQgrid and want to replace only default date to blank in date field of JQgrid.

please find code snippet for date field in JQGrid

     mtype: "GET"
     datatype: 'json',
     colModel: [
                {
                 name: 'Current_Linkage_Date', 
                 index:'Current_Linkage_Date', 
                 title: false, sorttype: "date",   formatter:'date',
                 formatoptions: { srcformat: 'Y-m-d H:i:s', newformat: 'd-M-Y',
                 defaultValue:null },
                    searchoptions: { sopt: ["eq", "lt", "le", "gt", "ge"] }
                         },
         ]

As back in controller I am getting null date as

 Current_Linkage_Date = row.Field<DateTime?>(13).GetValueOrDefault(),

Kindly help me to find how i can get blank value instead default date value.

Thanking in Advance.

The date type not support defaultValue:null, so it not works in your code.
