MySql commande gridview UPDATE

Question

J'ai cette grille:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
     CellPadding="4" DataSourceID="SqlDataSource1" ForeColor="#333333" 
     GridLines="None" DataKeyNames="id,email,first,last"> 
     <AlternatingRowStyle BackColor="White" /> 
     <Columns> 
      <asp:TemplateField ShowHeader="False"> 
        <EditItemTemplate> 
         <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True" 
          CommandName="Update" Text="Update"></asp:LinkButton> 
         &nbsp;<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" 
          CommandName="Cancel" Text="Cancel"></asp:LinkButton> 
        </EditItemTemplate> 
        <ItemTemplate> 
         <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" 
          CommandName="Edit" Text="Edit"></asp:LinkButton> 
         &nbsp;<asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" 
          CommandName="Delete" 
          onclientclick="javascript:return confirm('are you sure you want to delete.');" 
          Text="Delete"></asp:LinkButton> 
        </ItemTemplate> 
       </asp:TemplateField> 
      <asp:BoundField DataField="id" HeaderText="id" SortExpression="id"/> 
      <asp:BoundField DataField="email" HeaderText="email" SortExpression="email" /> 
      <asp:BoundField DataField="first" HeaderText="first" SortExpression="first"/> 
      <asp:BoundField DataField="last" HeaderText="last" SortExpression="last" /> 

     </Columns> 
     <FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" /> 
     <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" /> 
     <PagerStyle BackColor="#FFCC66" ForeColor="#333333" HorizontalAlign="Center" /> 
     <RowStyle BackColor="#FFFBD6" ForeColor="#333333" /> 
     <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" /> 
     <SortedAscendingCellStyle BackColor="#FDF5AC" /> 
     <SortedAscendingHeaderStyle BackColor="#4D0000" /> 
     <SortedDescendingCellStyle BackColor="#FCF6C0" /> 
     <SortedDescendingHeaderStyle BackColor="#820000" /> 
    </asp:GridView> 

Et ce SqlDataSource:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
     ConnectionString="<%$ ConnectionStrings:ClientrConnectionString %>" 
     ProviderName="<%$ ConnectionStrings:ClientConnectionString.ProviderName %>" 
     SelectCommand="SELECT * FROM Client;" 
     DeleteCommand="DELETE FROM Client WHERE id = @id AND email = @email;" 
     UpdateCommand="UPDATE Client SET first = @first WHERE id = @id;"> 

     <DeleteParameters> 
      <asp:Parameter Name="id" Type="String" /> 
      <asp:Parameter Name="email" Type="String" /> 
     </DeleteParameters> 
     <UpdateParameters> 
      <asp:Parameter Name="id" Type="String" /> 
      <asp:Parameter Name="first" Type="String" /> 
     </UpdateParameters> 
    </asp:SqlDataSource> 

J'excute une mise à jour, mais la valeur sont les mêmes, une idée pourquoi il est arrivé?

Answer 1

J'ai essayé la même chose. Ça marche pour moi. On dirait un problème avec le connectionstring.

J'ai donné le connectionstring qui a fonctionné pour moi.

J'utilise MySQL:

ConnectionString="server=localhost;user id=root;password=*****;persistsecurityinfo=True;database=coffeedb" ProviderName="MySql.Data.MySqlClient"
