Refresh Data For Gridview Without Reloading Page

In a page, there are one text box (textOrderby), one button and one gridview. (gridviewOrder)

I use dataset to bind gridview dynamically. Here is the code

dim SQL as string="select * from order where OrderBy = '" & textOrderby.text & "'"

dim ds as new dataset

ds=makedataset(SQL) // a function to make dataset

gridviewOrder.datasource=ds

gridviewOrder.databind

Every time once user input Order by data and then clicks the button, gridviewOrder will display new data.

It works fine but every time page is blinking (post back) to refresh data.

Is there any way to stop page blinking which still refresh data?
