[Solved] Invalid postback or callback argument in command item template

[mathieu]

HI,

I read a lot of articles about this problem but none answer my case :-(

So here is my problem:

I have a complex page with several user control and when i click on the linkbutton (or button) of the commanditemTemplate :

<CommandItemTemplate>

    <table class="rgCommandTable" border="0" style="width:100%;">

        <tr>

            <td style="text-align: left">

                <asp:Panel ID="MakeLotDistribution" runat="server">

                    <asp:Button ID="MakeLotDistributionButton" runat="server" CausesValidation="False" title="Faire un lot de distribution" CommandName="InitInsert" class="rgAdd" OnClientClick="if (!checkIfSelected(this)) return;" />

                    <asp:LinkButton ID="MakeLotDistributionlien" runat="server" CausesValidation="False" Text="Faire un lot de distribution" CommandName="InitInsert" OnClientClick="return checkIfSelected(this);" />

                </asp:Panel>

            </td>

            <td style="text-align: right">

                <asp:Button ID="RefreshButton" runat="server" Text=" " title="Rafraîchir" class="rgRefresh" />

                <asp:LinkButton ID="RebindGridButton" runat="server" CausesValidation="False" >Rafraîchir</asp:LinkButton>

            </td>

        </tr>

    </table>

</CommandItemTemplate>


I get this error in the javascript console:

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

i tried to add :

protected override void OnInit(EventArgs e)
{
    RadScriptManager.GetCurrent(this.Page).RegisterPostBackControl(this.DistributionItemGrid);
}

with this line i don't have the exception but that process a full postback and so the first radgrid is collapse..
i also tried with RegisterAsyncPostBackControl but i get the error like if there was nothing

here is the full hierarchy, i use dotnetnuke so i can't change the page validation
ascx ->
ascx -> radAjaxPanel -> radMultipage -> RadPageView ->
ascx -> radgrid -> Nesteviewtemplate -> 
ascx ->  radAjaxPanel -> radMultipage -> RadPageView ->
ascx -> RadAjaxPanel -> radgrid -> CommandItemTemplate -> LinkButton

Thank you very much for your time :-)

Hi Mathieu,

Based in the information provided it would be hard to determine what is causing this issue. Maybe the problem is DNN-related. To identify this, can you please check whether moving the grid outside of the DotNetNuke environment makes a difference? 

If the issue persists only in DNN, I suggest you to post your question in the DotNetNuke forums or contact the support of DNN for technical help with our products.

All the best,

i already check this but it change nothing it's not related to DNN

Hi Mathieu,

I am afraid that without a sample page in which the problem successfully replicates it would be hard to determine what is the root cause of the problem. Could you please provide additional code that could help us in reproducing the issue? Also please give us more information about your scenario.

hi,

thanks for the follow up,

but i'm sorry i currently don't have the time to export the code from my environment (DNN, my user control, DAL, etc) to send you a running project with the problem.

i found a workaround, in fact i figure out that the functionnality wasn't essential because i'n in a rush i supress the button that cause me the trouble so overkill the problem :-)

thanks
