Hi,

Call the Load Grid function again,that means

1) Get the data from the DB
2) the List/Dataset/Datatable assign to Grid.Datasource
3) call Grid.Databind() again

if i call the data from database again and bind to gridview,it shows old data in textbox of gridview.

If i don't call,keep it in !IsPostBack.Then Gridview vanishes on click of update link

You should call the code to retrieve the data after the call to update is complete. This way, the textbox value will be stored in the Database.

If I've got it completely wrong, please post some more of the code... i.e. how are you binding the code. update code.. etc..
