Access GridView Container Row Items from the Button Click Event

Assume Each GridViewRow contains Field1, Field2,.... Button:

 <asp:GridView ID="GridView1" Runat="server" DataSourceID="sdsDataSource"> 
<Columns>  
<asp:BoundField  DataField="Field1" HeaderText="Field1">
</asp:BoundField>  
<asp:BoundField  DataField="Field2" HeaderText="Field2">
</asp:BoundField>    .    .    .  
<asp:TemplateField>  
<ItemTemplate>  
<asp:Button ID="Button1" Runat=Server OnClick="Button1_Click" />  
</ItemTemplate>  
</asp:TemplateField>  
</Columns>  
</asp:GridView> 

To access the other items in the same row from inside the button click event, you need to find the corresponding GridViewRow in which the button is placed.

 
void Button1_Click(object o, EventArgs e)   
{ GridViewRow grdRow = (GridViewRow)Button1.Parent.Parent;    
  Button Button1 = (Button)o;  
GridViewRow grdRow = (GridViewRow)Button1.Parent.Parent;  
string strField1 = grdRow.Cells[0].Text;    string strField2 = grdRow.Cells[0].Text;    ...     }
