This example demonstrates how to implement property editors using our ASPxCheckBox and ASPxRadioButton controls to manage simple enumeration and flags properties:

[C#]
[Flags]publicenumComboboxEnum{None= 0,Value1= 1,Value2= 2 };publicenumRadioButtonEnum{Value1,Value2};[DefaultClassOptions]publicclassSampleObject:BaseObject{publicSampleObject(Sessionsession):base(session){}privateComboboxEnum_comboboxEnumProperty;publicComboboxEnumComboboxEnumProperty{get{return_comboboxEnumProperty;}set{SetPropertyValue("ComboboxEnumProperty",ref_comboboxEnumProperty,value);}}privateRadioButtonEnum_radioButtonEnumProperty;publicRadioButtonEnumRadioButtonEnumProperty{get{return_radioButtonEnumProperty;}set{SetPropertyValue("RadioButtonEnumProperty",ref_radioButtonEnumProperty,value);}}}

How to set this example as favorite?

Added By: Mohamed AIT LAHMID at: 2/21/2013 5:37:39 AM    

Thank you for your help.

I used RadioButtonEnumPropertyEditor :

        [Flags]
        public enum TopRecherche { Taxe = 0, Redevable = 1, LieuImposition = 2 };
         //..
        TopRecherche topRecherche;
        [ImmediatePostData]
        [ModelDefault("PropertyEditorType", "iclRegie.Module.Web.Editors.RadioButtonEnumPropertyEditor")]
        public TopRecherche TopRecherche
        {
            get { return topRecherche; }
            set
            {
                if (!IsLoading && !IsSaving && value != topRecherche)
                {
                    redevable = null;
                }
             }
        }
        p_Redevables redevable;
        [ImmediatePostData]
        public p_Redevables Redevable
        {
            get { return redevable; }
            set
            {
                SetPropertyValue<p_Redevables>("Redevable", ref redevable, value);
            }
        }

But the value of the property 'Redevable' is not changed when i changed the value of 'TopRecherche' in web page.

Added By: Sabine Dijt at: 8/27/2013 2:40:20 AM    

If I add more options to the enum it doesn't save right. It automatically checks every other option.
I'm using v13.1.5 btw. Is there any reason it wouldn't work in this version?

Added By: MohammedFarooq at: 11/20/2013 8:55:09 AM    

Can you post the equivalent code for v2013 vol 1.8?

Added By: Pauline Abou haidar at: 9/3/2014 4:20:12 AM    

Hi,
Please for the lines
radioButton.CheckedChanged += New EventHandler(AddressOf radioButton_CheckedChanged)

radioButton.CheckedChanged -= New EventHandler(AddressOf radioButton_CheckedChanged)

i need the equivalent in vb.net

and why if i put immediatepostdata= true for a property of radiobuttonenumpropertyeditor, it refreshes the selected value to the default every time i try to choose one.

Thanks and best regards

Added By: Dennis (DevExpress Support) at: 9/3/2014 12:43:26 PM    

@Pauline:

Hese is the VB.NET code you are looking for:

[VB.NET]
AddHandler radioButton.CheckedChanged, AddressOf radioButton_CheckedChanged
RemoveHandler radioButton.CheckedChanged, AddressOf radioButton_CheckedChanged

  

As for the behavior you described, it looks like an issue in this implementation. However, it is now obsolete and we no longer support this example code. I suggest you refer to the latest example mentioned in example's description.

How to bind a date-time chart range control client to a datasource and customize its common settings

This example demonstrates how to set up a range control with the date-time chart client to display a chart with date-time data in the range control's background.

In order to provide data to a chart date-time range control client, you need to access the ChartRangeControlClientDataProvider object using the ChartRangeControlClientBase.DataProvider property and assign a data source to the ChartRangeControlClientDataProvider.DataSource  property. Then specify the required data fields via the ChartRangeControlClientDataProvider.ArgumentDataMember, ChartRangeControlClientDataProvider.ValueDataMember, and ChartRangeControlClientDataProvider.SeriesDataMember (optional) properties.

In the current example, a date-time chart client is bound to a simple data table containing three columns ("Argument", "Value", and "Series").

In addition, this example shows how to customize chart client common settings (e.g., change the date-time range, customize template view and grid options).

There is an error in this sample

This part sets fixed range,

// Change the date-time range of the chart range control client.
dateTimeChartRangeControlClient1.Range.Min = new DateTime(2014, 7, 6);
dateTimeChartRangeControlClient1.Range.Max = new DateTime(2014, 7, 28);

while data generation uses DateTime.Now

row["Argument"] = DateTime.Now.Date.AddDays(pointIndex);

The code should be something like this :

// Change the date-time range of the chart range control client.
dateTimeChartRangeControlClient1.Range.Min = DateTime.Now;
dateTimeChartRangeControlClient1.Range.Max = DateTime.Now.AddDays(50);

Added By: Alexander T (DevExpress) at: 8/21/2014 12:42:31 AM    

Hi Al,

Thank you for the remark. We have corrected the example.

 

Added By: Samson Bassett at: 9/3/2014 2:47:23 PM    

Just wanted to thank you, as the DX docs are pretty terrible and this helped me a ton.

One error you have though is this

'DevExpress.XtraEditors.RangeControlDateTimeGridAlignment' is a 'type' but is used like a 'variable'

Perhaps you meant something like this

dateTimeChartRangeControlClient1.GridOptions.SnapAlignment = DevExpress.XtraEditors.RangeControlDateTimeGridAlignment.Day;

How to save a layout of LayoutControl together with its child controls

By default, if you save a layout of LayoutControl, settings of layout items are saved (Save and Restore Layout ). When you load the saved layout, layout items will be created with saved settings only if LayoutControl contains child controls, whose names exist in the saved layout. Otherwise, layout items will not be created. 

This example illustrates how to save settings of the child controls, too. For this, we have created two extension methods: SaveLayoutExToXml and RestoreLayoutExFromXml. These methods allow you to save and load child controls' settings. It makes sense to use these methods if it is necessary to re-create child controls from the saved layout with the saved settings. If a child control with the same name exists in LayoutControl, it will be removed and replaced by a new one retrieved from the saved layout. This approach is based on using a custom XmlXtraSerializer class.

How to create fully custom Role, User, Event, Resource classes for use with the Security and Scheduler modules

≪ Previous: How to add a watermark with a text or image to the document

This example demonstrates how to create fully custom classes for use in our Security Module (Complex Security Strategy) and Schedule Module.
Here is the Activity class, which is an analog of our standard Event class. It is used to represent appointments in the Scheduler Control.
The Employee is an analog of the standard User class. The Group class is an analog of our standard Role class. Two last classes are used as base classes to organize Complex Security Strategy for your application.
Take special note that in addition to security purposes, the Employee class supports the IResource interface, and this allows us to use objects of this class as resources in our custom "appointment" class.
I have also implemented two popular filtering tasks here: filtering appointments by the current logged employee and also filtering resources to show only those owned by the current logged employee.

IMPORTANT NOTES
1. When you implement this solution in your project, do not forget to turn on custom security classes by setting the RoleType and UserType properties for the Security Complex component within the Application Designer.
2. The filtering appointments and resources (plus sorting of resources) is provided by the SchedulerActivityListViewControllerBase class and its descendants. Please take special note that these controllers filter resources as follows:
   a. Administrator account (Sam, to log on, leave the Password field empty) sees all the resources and appointments in the root scheduler view.
   b. Non-Administrator account (John, to log on, leave the Password field empty) sees only his own resources and appointments in the root scheduler view.
   c. Both Administrator and Non-Administrator accounts see their own resources and appointments in the nested scheduler view.

3. You can use these controllers for study purposes, since they demonstrate the most common filtering scenarios in the scheduler view. If you do not need all this specific functionality, remove these controllers and create your own ones (perhaps based on the provided example code) that will do only your specific task. For example, the controllers from this example are not suitable in the nested scheduler view because you miss some part of the default Link/Unlink functionality since the scheduler view is always filtered to show only its own resources and appointments.That may not be desired because you may want to have the capability to link appointments from other resources, but they won't be shown due to the above. Plus, these demo controllers are unnecessary for appointments filtering in the nested scheduler view, because by default, in this view only appointments from the current resources are shown.

This example illustrates how to create an appointment and resource model by using Code First development and then use the types defined in the model as data sources for the SchedulerStorage component in the XtraScheduler WinForms application.

The Color property of the Resource does not necessarily have to be split into ARGB components in the database. It is done in this project for illustrative purpose only. Note that the ColorSaving property determines how resource color value is interpreted.

For a walkthrough on data binding with Windows Forms refer to the MSDN article Entity Framework: Data Binding with Windows Forms.

To use TileBar according to the MVVM, pattern, you can generate TileBarItems from a collection. To accomplish this task, assign a collection to the TileBar.ItemsSource property. To change properties of generated TileBarItems, use the TileBar.ItemContainerStyle property. If it's necessary to build a multi-level hierarchy, put TileBar into TileBarItem.FlyoutContentTemplate.

The following example demonstrates how to obtain client data corresponding to a particular visual element using ASPxDashboardViewer's client-side API.

In this example, the ASPxClientDashboardViewer.ItemClick event is handled to obtain client data and invoke the dxPopup widget with the child dxChart.

In the event handler, the ASPxClientDashboardItemClickEventArgs.GetData method is called to obtain dashboard item's client data. The ASPxClientDashboardItemClickEventArgs.GetAxisPoint method returns the axis point corresponding to the clicked card while the ASPxClientDashboardItemData.GetSlice method returns the slice of client data by this axis point.
To obtain axis points belonging to the "Sparkline" data axis, the ASPxClientDashboardItemDataAxis.GetPoints method is used. Corresponding actual/target values are obtained using the ASPxClientDashboardItemData.GetDeltaValue method.

The dxChart is used to display the detailed chart showing a variation of actual/target values over time.

Hello All,

When I use this editor directly in a DevExpress.XtraBars.Ribbon.RibbonForm the Designer generates this code:

            //
            // tsEditDuration
            //
            this.tsEditDuration.EditValue = System.TimeSpan.Parse("00:00:00");
            this.tsEditDuration.Location = new System.Drawing.Point(74, 50);
            this.tsEditDuration.MenuManager = this.ribbon;
            this.tsEditDuration.Name = "tsEditDuration";
            this.tsEditDuration.Properties.Buttons.AddRange(new DevExpress.XtraEditors.Controls.EditorButton[] {
            new DevExpress.XtraEditors.Controls.EditorButton(DevExpress.XtraEditors.Controls.ButtonPredefines.Combo)});
            this.tsEditDuration.Properties.DisplayFormat.FormatString = "HH:mm:ss";
            this.tsEditDuration.Properties.EditFormat.FormatString = "HH:mm:ss";
            this.tsEditDuration.Properties.Mask.EditMask = "HH:mm:ss";
            this.tsEditDuration.Size = new System.Drawing.Size(100, 20);
            this.tsEditDuration.TabIndex = 0;

So far everythings are fine.

But when I use this editor in a custom control derived from DevExpress.XtraEditors.XtraUserControl the Designer generates this code:

            //
            // tsEditDuration
            //
            this.tsEditDuration.EditValue = System.TimeSpan.Parse("00:00:00");
            this.tsEditDuration.Location = new System.Drawing.Point(215, 110);
            this.tsEditDuration.Name = "tsEditDuration";
            this.tsEditDuration.Properties.Buttons.AddRange(new DevExpress.XtraEditors.Controls.EditorButton[] {
            new DevExpress.XtraEditors.Controls.EditorButton(DevExpress.XtraEditors.Controls.ButtonPredefines.Combo)});
            this.tsEditDuration.Properties.DisplayFormat.FormatString = "HH:mm:ss";
            this.tsEditDuration.Properties.EditFormat.FormatString = "HH:mm:ss";
            this.tsEditDuration.Properties.EditValueChangedFiringMode = DevExpress.XtraEditors.Controls.EditValueChangedFiringMode.Default;
            this.tsEditDuration.Properties.Mask.EditMask = "(0(\\R.([0-1]\\d|2[1-3])|\\d)|1(\\R.(0\\d|1[0-1])|\\d)|2\\d|3[0-5])\\R:[0-5]\\d\\R:[0-5]\\d";
            this.tsEditDuration.Properties.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.RegEx;
            this.tsEditDuration.Size = new System.Drawing.Size(89, 20);
            this.tsEditDuration.TabIndex = 14;

In the second case I can't edit the value. The EditMask string is displayed instead of the actual value. As a workaround you need to edit the designer generated code.

Regards,
Arnaud.

I have tried to replicate the issue but have not noticed any issues. If you still experience the same problem, please create a separate ticket regarding it and describe the issue in greater detail. A sample project demonstrating the problem will be very helpful.

Hi,
How can I force the format to be like 00:00:00 instead of 0:00:00?
I tried changing the culture fed to the manager or the _Hxxx in FormatInfo but they seem to be the wrong place.
Thanks.

Hello,
To accomplish this task, create a new Class Library project and then replace default code with custom control class code.

Should you have further questions, let me know.

This example demonstrates how to display a check box within column headers. If the check box is checked, the corresponding column is made read-only. Uncheck the check box to allow column values to be edited.
