Question

I have a GridView that is bound to an ObjectDataSource, and I am handling the full row select using the standard solution provdided all over of putting this line in the OnRowDataBound():

e.Row.Attributes['onclick'] = this.Page.ClientScript.GetPostBackEventReference(this, 'Select$' + e.Row.RowIndex); 

All of this is working swimmingly, except that I am noticing my ObjectDataSource is being hit each time the row selection changes. I am not doing a BindData() anywhere in the row selection code behind, and since the data isn’t changing as a result of the select I really don’t see why the grid needs to rebind. I am letting the gridview handle paging and sorting, but again, selection doesn’t change the contents so I don’t think that should effect it.

I have tried turning the view state on for the grid (very small amount of data) and it had no effect. I set the UpdatePanel to conditional updates and children as triggers=false, but that caused the data to still be queried but no update to occur to the screen (LOL!).

Any GridView gurus out there want to take a stab at this one?

Are you missing the following in your Page_Load():

If (!IsPostBack) {  } 

This is something developers miss a lot! Follow your events and you’ll likely see that somewhere an event is fired OnPostBack and you’re calling your DB code.
