coollife -4 Junior Poster in Training

while i was editing the <asp:data grid>.............

tag in the source part . i by mistake deleted the closing tag and pressed f5 and it gave error and it didnt allow me to correct it .

Finally i restarted the visual studio and later it was allowing me to make correction and after correction i pressed save and even after
ten mins document didnt get saved.

Please tell me the solution for this ............
