asp.net - Display GridView while others still load -

i new asp.net/c#. came across asp:updatepanel control in asp.net. have multiple gridviews in page. trying achieve display gridviews , when loaded.

say instance, first gridview data loaded data source , databound grid. how can use updatepanel show results user while other gridviews still being loaded?

note: achieve this, using flag , timer. timer set trigger in updatepanel on every tick of timer, check if data loaded using flag. if so, call databind() method displays data on page while others still being processed.

if set update mode of updatepanel conditional, after databind() should call .update() such

gridview1.databind(); updatepanel1.update();
