    Not catching the postback event ?

    Hi
     
    Its strange. I have suddenly lost the postback event. If I make a clean example of including an editor (Editor1) in a aspx and include the following in the codebehind:
    Private Sub Editor1_PostBackCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs)
    If String.Compare(e.CommandName, "Save", True) = 0 Then
    Label1.Text = "gem KNAPPEN"
    End If
    End Sub

    Nothing happens. It seems that the event is not fired when hitting the save button.

    Any ideas ?

    regards
    Lars Kohsel

    Just wanted to say that it has worked before and also works on the production server CE v4.0.0.4.

    Re: Not catching the postback event ?

    Did the VB.NET code miss something ?
     
    Private Sub Editor1_PostBackCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) Handles Editor1.PostBackCommand

    ?

    Re: Not catching the postback event ?

    I got the catch_save_button_click working, but my application still does not catch the postbackevent. Can other usercontrols in the page interfere with a postback event ?
     
    I have put in a skmMenu in the top.

    The save button causes a postback but the sub below is not catched ????
     

    PrivateSub Editor1_PostBackCommand(ByVal Sender AsObject, ByVal e As System.Web.UI.WebControls.CommandEventArgs) Handles Editor1.PostBackCommand

    IfString.Compare(e.CommandName, "Save", True) = 0 Then

    savedata()

    'dataBinder()

    EndIf

    EndSub

    Re: Not catching the postback event ?

    Found a new bug !

    just spent half a day messing around with my code and testing your sample code just to find that the

    Editor1.DisableItemList = "InsertTextBox, InsertInputSubmit, InsertInputReset, InsertInputText, InsertInputPassword, InsertInputhidden, InsertListBox, InsertDropDown, InsertCheckBox, InsertRadioBox"







     
    in the page_load sub messes up the postback event.





    Not very happy

    Re: Not catching the postback event ?

    Lars Kohsel :
     
    Currently for this bug , you could set the DisableItemList on the page's Init event handler .

    Re: Not catching the postback event ?

    I got the same lost postback event problem but I was using
    Editor1.AutoConfigure = CuteEditor.AutoConfigure.Full_noform
     
    In my page_load event
     
    The fix worked ok but you need to use InsertForm instead of Form to get rid of the Form icon from the toolbar

    I'm not so sure we have nailed the bug nor the fix here. I lose events too, but because I
    change the property myEditor.ConfigurationPath upon an event  (SelectedNodeChanged)  caught from another control. Changing certain properties seems to do something with the editor object that causes events to lose track... I'm not very into the inner working of event handling so I don't have any explanation to why, but it sure smells like a bug in CuteEditor.
     
    I can't do a workaround in Page_Init, because other obejcts i need properties from have yet not been initialized at that stage.
     
    Tips?
     
    edit: Just to be clear, the change of configurationPath causes the event on the NEXT postback to be lost, not the one in progress. I.e. the line 'myEditor.PostBackCommand += new CommandEventHandler(myEditor_PostBackCommand);' doesn't seem to have any effect that particular cycle.

    Re: Not catching the postback event ?

    I am also having this same problem with the current version 6.5.  This is what happens.
     
    I have created a custom drop down list and added it to the editor.  This drop down list posts back, adds text to the edior, and enables or disables buttons based on the value of the drop down list.  If I remove the code which disables and enables buttons, the drop down will continue to post back.  If the code is added back, the drop down will only post back once...any subsequent post backs are lost.
     
    Has any one found a solution for this problem?  I really need to disable the save button based on the permissions of the file that was chosen by the user with the drop down.  Currently, I cannot do this because of the post back problem.

    Re: Not catching the postback event ?

    Sorry it took me so long to get back to you.  I was out of town for a week. 
     
    Here's the code behind to create the drop down as well as the events that correspond to it. 
     
     

     

    override protected void OnInit(EventArgs args)
        {
            Editor1.Initializing += new System.EventHandler(Editor1_Initializing);

            base.OnInit(args);
        }

            templateDd.Font.Size = 10;
            ListItem item = new ListItem();
            item.Text = "Select Custom File";
            item.Value = "0";
            templateDd.Items.Add(item);
            templateDd.AutoPostBack = true;
            templateDd.CssClass = "CuteEditorDropDown";
            SqlConnection conn = new SqlConnection(datasource);

    Hello Again,
      I posted my source code, do you have any feedback or a fix for this issue?  Thanks.

    Re: Not catching the postback event ?

    I am still having this issue, and have not found a work around.  In fact, the postback problem has grown in scope.  If I change the style sheet based on a custom drop down list using this code based on the style sheet chosen by the user, any subsequent postbacks are lost.
     

    Editor1.EditorWysiwygModeCss = "~/Default.css"

     
    Is there anyway at all to resolve this issue?  I've been waiting for well over a month for a response.  Thank you.
