Datalist ItemCommands

~Bean~ · August 15th, 2006, 08:37 AM

I am in the process of porting a 1.x project to 2.0. My problem is in a datalist I have - the ItemCommand, EditCommand, DeleteCommand, etc. are no longer firing. Not just the Code itself, but there is NO postback whatsoever. Any ideas why no postback?

Code:

<asp:datalist id="dlContact" runat="server" datakeyfield="id" OnItemCommand="dlContact_ItemCommand" OnEditCommand="Edit_Command" borderstyle="None">
        <itemstyle borderstyle="None"></itemstyle>
        <itemtemplate>
            <asp:linkbutton id="Lbtnplayer_ID" Runat="server" CommandName="Select">Select</asp:linkbutton>
<asp:linkbutton text="Edit" commandname="Edit" runat="server" id="lnkEditContact" commandargument='1' />
</itemtemplate>
    </asp:datalist>


============================================

Sub dlContact_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles dlContact.ItemCommand
        Response.Write("Client Item Command: " & e.CommandName & " Argument: " & e.CommandArgument)
    End Sub

the only thing I can think of is that the master page is somehow interfering with it...(?)

That's odd.

What does the final HTML in the browser look like?

It look slike this:

Code:

<table id="ctl00_cpContent_dlContact" cellspacing="0" border="0" style="border-style:None;border-collapse:collapse;">
    <tr>
        <td style="border-style:None;">
            <a id="ctl00_cpContent_dlContact_ctl00_Lbtnplayer_ID" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$cpContent$dlContact$ctl00$Lbtnplayer_ID&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))">Select</a>
            <a id="ctl00_cpContent_dlContact_ctl00_lnkEditContact" class="buttonTextandImg" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$cpContent$dlContact$ctl00$lnkEditContact&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))">Edit</a>
        </td>
    </tr><tr>
        <td style="border-style:None;">
            <a id="ctl00_cpContent_dlContact_ctl01_Lbtnplayer_ID" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$cpContent$dlContact$ctl01$Lbtnplayer_ID&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))">Select</a>
            <a id="ctl00_cpContent_dlContact_ctl01_lnkEditContact" class="buttonTextandImg" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$cpContent$dlContact$ctl01$lnkEditContact&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))">Edit</a>                        
        </td>
    </tr>

    etc.

That looks pretty normal, I'd say.

I assume the code for WebForm_DoPostBackWithOptions is also present in your page?

With your previous 1.x code, did you get <a href> tags with a JavaScript function as well?

Aha!

That was not the exact problem, but while looking over the source I noticed the js for a required field validator further up on the page. The page was not posting back because the validator was keeping it from doing so (and I had it hidden so I didn't even see it). All I needed was a tweak to that and it looks OK now...

Thanks Imar...
