Populate a javascript message box

Question

hello there.

this is the code behind from asp net page, I don't have error.

I have two questions:

• Why when you update the value of the pieces in the gridview doesn't refresh the data required by the update query ?
• to display correct update data I need refresh the web page...
• Why RegisterClientScriptBlock doesn't work in GridView1_RowUpdated ?

Could you please help?
Thanks you very much for your help.
