Keep inner gridview after postback in Asp.net using Jquery

Question

I have nested GridView with Expand Collapse feature in ASP.Net using VB.Net.Using Jquery i am able to expand collapse and show another gridview.

 

The expand collapse feature is working fine .

 

 

What my requirement is that even after postback i want to retain inner gridview in UI .

But it would not be there once postback happens.

 

I tried to use State saving option of Datatable but it will save the state of + icon but inner datagrid view wont be retained .

 

Is there anyway we can address this issue ?

 

Thanks
