Hi,
The Grid does not do auto postback for you. However you can handle the GridColumn's ClientSideEndEdit with JavaScript. Inside your handler you can do anything possible with JavaScript, including a post back. The code will be something like this:
    
        Code: HTML/ASPX
        
        <eo:Grid .....>
    <Columns>
        ....
        <eo:TextBoxColumn ClientSideEndEdit="end_edit_handler" ....>
        </eo:TextBoxColumn>
        ....
    </Columns> 
</eo:Grid> 
     
 
    
        Code: JavaScript
        
        function end_edit_handler(cell, newValue)
{
    //Use a timer to delay the post back so that the
    //new value got saved by the Grid first
    setTimeout(function()
    {
       //Raising post back
        __doPostback(....);
    }, 10);
} 
     
 
You can also uses a ScriptEvent control and call eo_TriggerServerEvent instead of __doPostBack to trigger post back. eo_TriggerServerEvent triggers a post back and fires the corresponding ScriptEvent's Command event.
Thanks
