I have some issue with ASP.net Gridview that I hope people here can help me.
Requirements
- Gridview whole row to be clickable to open another page
- In editing mode, can change table values through edititemtemplate textbox
Problem
Textbox selection causes the entire row click event to fire and prevents user from changing the textbox text. User can edit table value without opening different page.
ASP Page
