Nested ListView KeyProperty 'wrong'

created 7 years ago

Hello dear supporters,

I have a problem that allways at the first try in a Webapplication the Keyproperty-Value of an nested Listview is not correctly delivered by the 'ASPXGridView' which is behind and I get an ArgumentException…

Is there any 'model' setting which i have not done?

Code
The error occurred:  

    Type:       ArgumentException  
    Message:    Cannot convert the 'WPS5.Module.BusinessObjects.Schweisser(493)' value to the type of the 'WPS5.Module.BusinessObjects.Schweisser' key property type, error: Die Eingabezeichenfolge hat das falsche Format.  
    Data:       0 entries  
    Stack trace:  

   bei DevExpress.ExpressApp.Xpo.XPObjectSpace.GetObjectKey(Type objectType, String objectKeyString)  
   bei DevExpress.ExpressApp.Web.Editors.ASPx.ASPxGridViewContextMenu.SelectObject(String objectId)  
   bei DevExpress.ExpressApp.Web.Editors.ASPx.ASPxGridViewContextMenu.ProcessCommand(String args)  
   bei DevExpress.ExpressApp.Web.Editors.ASPx.ASPxGridViewContextMenu.DevExpress.ExpressApp.Web.Templates.IXafCallbackHandler.ProcessAction(String parameter)  
   bei DevExpress.ExpressApp.Web.Templates.XafCallbackManager.ProcessAction(String parameter)  
   bei DevExpress.ExpressApp.Web.Templates.XafCallbackManager.callbackControl_Callback(Object source, CallbackEventArgs e)  
   bei DevExpress.Web.ASPxCallback.OnCallback(CallbackEventArgs e)  
   bei DevExpress.Web.ASPxCallback.RaiseCallbackEvent(String eventArgument)  
   bei DevExpress.Web.ASPxWebControl.System.Web.UI.ICallbackEventHandler.RaiseCallbackEvent(String eventArgument)  
    InnerException is null

Can anyone give me a hint, why that happens.
And why it only happens at the first 'time'. When I press 'back' in the exceptionhandling message and do the 'Action' again, all works perfectly well.

Thank you
Thomas

        Hello, Thomas.

        UPDATED:
        We researched the issue and found that the optimized processing of the default list view action is broken by a syntax error in the script produced by your WebGridLookupPropertyEditor implementation. In the WebGridLookupPropertyEditor.AddClientSideEvents method, you are using the following code:

        C#
        ((WebApplication)application).PopupWindowManager.GetShowPopupWindowScript(newObjectWindowAction,GetNewObjectAddedCallbackScript(control),control.ClientID,false,true)

        The GetNewObjectAddedCallbackScript method creates a script that is inserted into the outer script without escaping single quotation marks.
        You can fix the script error and the original issue as follows:

        C#
        string cbscript = GetNewObjectAddedCallbackScript(control).Replace("'", "\\'");  
string subscript = ((WebApplication)application).PopupWindowManager.GetShowPopupWindowScript(newObjectWindowAction, cbscript, control.ClientID, false, true);

        I also recommend that you use the DevExpress.ExpressApp.Web.Utils.ClientSideEventsHelper.AssignClientHandlerSafe method to attach client side event handlers that do not overwrite scripts attached by the XAF framework.

            Thank you for your hints.
            Now it works as expected.
            But I wonder why i have to use
            DevExpress.ExpressApp.Web.WebApplication.OptimizationSettings.AllowFastProcessListViewRecordActions = false;as that is decreasing Performance.

            Is there any way how I can use 'custom' client event handler without settion the above property to true?

            Yours Thomas
