    [CLOSED] [1.0] MenuItem Click DirectEvent

    Hi,

    I have a problem with the following code. It worked well with 0.8.2.

    It is context menu attached to TreePanel. When I click on a MenuItem it gives me "Request Failure", status code 500.

    
    ->TreePanel
    
    ...
    
    <Listeners>
     <ContextMenu Handler="#{cmenu}.node = node; node.select(); #{cmenu}.showAt(e.getPoint());" />
    </Listeners>
    
    ->Context Menu
    
    <ext:MenuItem ID="mnDisAbilita" runat="server" Text="disabilita voce di menu" Icon="ApplicationOsxDelete">
                    <DirectEvents>
                        <Click OnEvent="MB_Deny_Click">
                            <ExtraParams>
                                <ext:Parameter Mode="Value" Name="prmNodeIdDeny" Value="={#{cmenu}.node.id}">
                                </ext:Parameter>
                            </ExtraParams>
                        </Click>
                    </DirectEvents>
                </ext:MenuItem>
    
    ->Code
    
    protected void MB_Deny_Click(object sender, DirectEventArgs e)
    {
                string _id = e.ExtraParams["prmNodeIdDeny"].ToString();
                if (_id == "0") return; 
                ...
    }
    ViewState is enabled.

    Do I have to change code?

    Thanx

    Matteo

    RE: [CLOSED] [1.0] MenuItem Click DirectEvent

    Hi,

    I am sure that status code 500 is consequence of server side exception. Try to set breakpoint inside MB_Deny_Click. Do you reach it?


    Please create simple example which reproduces the problem

    Hi Vlad,

    no, I tried it, but it didn't reach server side code.

    I'll prepare a simple example and post it.

    Hi,

    You can press Alt-Ctrl-E in VS to catch all exception (check checkbox for Common Language Runtime Exceptions). Then VS will show where exceptions occur

    RE: [CLOSED] [1.0] MenuItem Click DirectEvent

    Hi Vlad,

    I reproduced the error, the event stopped before entering server side code!?

    However it was my fault, I decided to print in red the resource - treenode - not enabled.

    To do this I added a tag to the node text.

    In the code below, if you remove the tag it works fine.

    Can you suggest an error safe solution to render the text node colored?

    RE: [CLOSED] [1.0] MenuItem Click DirectEvent

    Hi,

    I see, you have "A potentially dangerous Request.Form value was detected from the client" exception.
    You can set ValidateRequest="false" for the Page or use Cls property for TreeNode to set red color

    RE: [CLOSED] [1.0] MenuItem Click DirectEvent

    Hi,

    Or you can disable selection submit (see SelectionSubmitConfig property of the TreePanel, DisableAutomaticSubmit)

    RE: [CLOSED] [1.0] MenuItem Click DirectEvent

    Perfect, thanx Vald.

    I'll post my code here:

    
    CSS
    
    .nodeDisabled .x-tree-node-anchor span{ color:Red !important; }
    
    C#
    
    ...
    asyncNode.Cls = "nodeDisabled";
