[Solved] ItemHierarchicalIndex

[RvdGrint]

Hello,

I've a RadGrid with a ButtonColumn of type ImageButton. When adding an CommandArgument to this column the error: 'Specified argument was out of range of valid values. Parameter name: ItemHierarchicalIndex'.

<telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="~/Images/RadGrid/16pxSearch.png" CommandName="Edit" CommandArgument="View" UniqueName="ViewColumn">
  <HeaderStyle CssClass="rgHeader ButtonColumnHeader"></HeaderStyle>
  <ItemStyle CssClass="ButtonColumn"></ItemStyle>
</telerik:GridButtonColumn>

Anyone any idea how to fix it??

I've some additional information.

I've defined an OnCommand client-event for this RadGrid. When removing the event the error doesn't occur, but I need that OnCommand event for disabling AJAX for some commands.

<ClientSettings>
  <ClientEvents OnCommand="gridCommand" />
</ClientSettings>

function gridCommand(sender, args) {

    if (args.get_commandName() == "DownloadAttachment") {

        var gridID = sender.get_id();
        var grid = document.getElementById(gridID);

        var manager = $find(grid.parentNode.parentNode.id);

        if (manager) {
            manager.set_enableAJAX(false);

            setTimeout(function () {
                manager.set_enableAJAX(true);
            }, 0);
        }
    }

Hello Jos,

When the OnCommand event is attached the command is fired from the client with the fireCommand method. It expects the argument for the Edit command to be the hierarchical index of the current edited item. It your case the argument is the string "View" which causes exception. You should either pass the correct argument to the edit command or you can use another event to cancel some of the ajax command such as the OnRequestStart of the AjaxManager.
