Datagrid VS ViewState

This week, I try to optimized my web application which using 10 million record.

The first thing that I notice that EnableViewState by default is set to true.

So my datagrid will store all the view state into client. so every time there is postback or asyn postback, it will transfer heaps of data through networks. and It is not very efficient.

So I try to disable them by EnablingViewState = false.
However by disabling view state in the data , all the events in datagrid is not fired..


one of the solution is to disable view state on each item.
_dg.DataBind();
foreach (DataGridItem item in _dg.Items)
{
item.EnableViewState=false;
{


however, if your all commandArguments is not work,..

so the other solution is you need to bind every time in page back...
