  you can use query string

  try this

  <asp:Button ID="BtnEditar" runat="server" Text="Editar" PostBackUrl="~/editar.aspx?<%#Eval("id")%>" />

  i am not sure but you can try this

  hope this will help

  if(Hard_Work && Luck)
  Response.Write("Success");
  
  
  Best Of Luck

  Cut how to get the Id (datakey gridview) with a button

  protected void Button1_Click(object sender, EventArgs e)
  {
          Button b = (Button)sender;
          GridViewRow row = (GridViewRow)b.NamingContainer;
          if (row != null)
          {
               //Get the Row Index
               int rowIndex = row.RowIndex;
               //Get the DataKey value
               string key = GridView1.DataKeys[rowIndex].Value.ToString();
               //Get the Row value of BoundField
               string rowValue = row.Cell[0].Text;
               
          }
  }

  <asp:Button ID="BtnEditar" runat="server" Text="Editar" PostBackUrl="~/editar.aspx" />

  You may want to remove the PostBackUrl of the Button so that the code behind your Button will fire. You can use plain Response.Redirect instead.
