Question

This my data list:

     <asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" 
               RepeatLayout="Flow">
            <ItemTemplate>
                Titre:
                <asp:Label ID="TitreLabel" runat="server" Text='<%# Eval("Titre") %>' />
                <br />
                Description:
                <asp:Label ID="DescriptionLabel" runat="server" 
                    Text='<%# Eval("Description") %>' />
                <br />

                <asp:Image ID="Image1" runat="server" 
                 ImageUrl='<%# Eval("ID", "Handler.ashx?ID={0}") %>' Width="200" Height="200"/>

                <br />
                comments:
                <asp:Label ID="commentsLabel" runat="server" Text='<%# Eval("comments") %>' />
                <br />

                Ajouter commentaire 
                <asp:button ID="btnAjouter"  runat="server" Text="Ajouter" />
                <br/>
                <br/>
            </ItemTemplate>
        </asp:DataList>

In the Vb.aspx code I create a method:

public Sub updateComments()
.......
End Sub

And I want to add an event to my DataList button and excute the method.

I don’t know how to do it correctly.

This is in Vb.net.

Thanks

You just need to add a CommandName to your button and handle the DataList’s ItemCommand.

For example(in ItemTemplate)

<asp:button ID="btnAjouter" CommandName="Ajouter"  runat="server" Text="Ajouter" />

In Codebehind:

Sub Item_Command(sender As Object, e As DataListCommandEventArgs)Handles DataList1.ItemCommand
    If e.CommandName = "Ajouter"
        '  do something '
    End If
End Sub
