DataRepeater OnCommand multiple CommandArgument

Is it possible to pass several arguments inside a CommandArgument parameter to the ItemCommand handler for the ASP.NET Repeater?

I have a table that I render with several columns, pretty basic, I just need one linkbutton, when clicked on it, I need to pass 3 parameters to the onclick function, all three are the data bound parameters. There doesn't seem to be a way of doing so, aside from using CSV format(which will not work for me, since the values themselves can contain commas).

So, is this possible to pass p_field1, p_field2 and p_field3 as per in the code below. Thanks!

<asp:Repeater ID="rptId" runat="server" EnableViewState="true" OnItemCommand="rptId_ItemCommand">
                                <ItemTemplate>
                                <tr align="center" class='<asp:Literal ID="litRowClass" runat="server" />'>
                                    <td><%#Eval("p_开发者_Go百科field1")%></td>
                                    <td><%# Eval("p_field2")%></td>
                                    <td><%# Eval("p_field3")%></td>
                                    <td><%# Eval("p_field4")%></td>

                                    <td><asp:LinkButton runat="server" ID="lnkBtnId" CommandArgument='<%# Eval("p_field1") %>' CommandName="testCommandName">MARK</asp:LinkButton></td>                  




                                </tr> 
                                </ItemTemplate>
                            </asp:Repeater>

Unfortunately, you can't pass in multiple fields without a "CSV" style format; only a single string is allowed.

You'll have to do some string concatenation and then split it back out OnCommand. Pick some delimiter that won't be in your parameters, below I used |.

<asp:Repeater ID="rptId" runat="server" EnableViewState="true" OnItemCommand="rptId_ItemCommand">
    <ItemTemplate>
        <tr align="center" class='<asp:Literal ID="litRowClass" runat="server" />'>
            <td><%#Eval("p_field1")%></td>
            <td><%# Eval("p_field2")%></td>
            <td><%# Eval("p_field3")%></td>
            <td><%# Eval("p_field4")%></td>
            <td><asp:LinkButton runat="server" ID="lnkBtnId" CommandArgument='<%# Eval("p_field1") + "|" + Eval("p_field2") + "|" + Eval("p_field3")  %>' CommandName="testCommandName">MARK</asp:LinkButton></td>                  
        </tr> 
    </ItemTemplate>
</asp:Repeater>

You'd then need something like the following in rptId_ItemCommand:

string[] arguments = CommandEventArgs.CommandArgument.Split('|');

CommandArgument='<%# JoinFields(Eval("p_field1"), Eval("p_field2"), Eval("p_field3")) %>'

You could use what you want as separator(f.e. the pipe |). You could easily split these values on serverside. To join these field you could use a helper-function like this:

Protected Function JoinFields(ByVal p_field1 As Object, ByVal p_field2 As Object, ByVal p_field3 As Object) As String
   Return String.Join("|", New Object() {p_field1, p_field2, p_field3})
End Function
