Limiting view state information on AJAX calls

Question

I have an Entry Form and a GridView on the same page. Selecting a row from the GridView populates the TextBoxes in the Entry Form above it with all the entries of the GridVi

Answer 1

I agree with Kevin M and Aristos. Additionaly there is another way how to minimize transfered ViewState size: store it on server side using custom viewstate provider. This article describes how to create such provider: http://www.codeproject.com/Articles/8001/ViewState-Provider-an-implementation-using-Provide.

What pitfalls arise by using a custom view-state provider?
